With regards to thunderbolt vs. USB 3.0

Thunderbolt is much more powerful with faster data transfer than USB 3.0. However, don't forget that the average person will not be using a SSD as backup. Especially as a 1 TB mechanical drive sells for less than $100. One of the main requirements for these drives is SIZE not SPEED (especially as a SSD with a capacity of greater than 256 GB is prohibitively expensive to most people). The only way thunderbolt will beat USB 3.0 is if the backup is being done to a SSD (which will not be used in 99% of the cases because of price and size restraints). You may have a Ferrari with a 500hp engine but you are limited by the speed limit (less than a third the top speed of that Ferrari). Since most don't use and SSD for backup there is not point for them to use thunderbolt. And most don't backup 100+GB of data a day (backups are perhaps every week and involve on average less than 5GB).

It does not have to be the best, it simply has to be good enough.

It seems a perfectly logical decision to postpone thunderbolt in hp computers.
 
3840x2160x60 Hz > 4096x2160x24 Hz

Show me a 3840x2160 60Hz display please. That isn't a non-consumer large HDTV.

Resolution support is a non-issue anyway, seeing as how there isn't a single Apple system that could fluidly run any non-basic graphics at such a high resolution. The Mac Pro can't even handle GPU solutions that would be able to push that sort of resolution in Windows, since the Mac Pro PSU can't supply the required power and it only has one PCIe x16 slot.

DP 1.2 is 21.6 Gbps, HDMI 1.4a is 10.2 Gbps

Doesn't change the fact that HDMI supports higher resolutions and has more features.

DP also supports the Blu ray lossless audio codecs. The reason HDMI is dominant is because it was around first and is good enough right now, not because it is superior to DP.

In PCs? Not quite. DisplayPort was approved in May 2006, before HD DVD and blu-ray drives were available for PC.

HDMI won because it is the better connector.

Not so. Most high-end PC graphics cards are shipping with either DisplayPort or Mini DisplayPort among their connectors.

Some Radeon. Virtually no nvidia. If you go to newegg, you see 109 results for 1 full size DisplayPort, 4 1x mini DisplayPort, 59 2x mini DisplayPort. Yet there are 404 GPUs with HDMI output and 140 with mini HDMI.

Max Resolution
Display Port 1.2 = 3840x2400 = 9,216,000 pixels
HDMI 1.4a = 4096*2160 = 8,847,360 pixels

Display Port has ~4% higher resolution at over twice the frequency

Can you really not comprehend this? 3840x2400>4096x2160

I really did not think I had to explicitly show the math.

Before you cite a number, it helps to understand what the number is referring to

The max resolution for display port can be found in my previous links and countless others on the web and you will find it is 3840x2400 across the board

Well, I hate to prove you wrong again, but heres another link: http://www.reghardware.com/2009/01/13/displayport_1dot2_basics/

And another one http://www.hdtvinfo.eu/news/hdtv-articles/displayport-1.2-specification.html

And another http://xtreview.com/addcomment-id-7551-view-DisplayPort-1.2-specification.html

And, yet again, if DisplayPort 1.2 supported a DVDs worth of extra pixels over HDMI 1.4, why does it matter when there isn't a single Apple computer on the planet that could push that sort of resolution fluidly beyond basic text display? Again, the Mac Pro doesn't support GPUs that would be capable of that kind of pixel pushing. So…………..

By the time Apple has systems capable of pushing that sort of resolution smoothly, in 10 years or so considering how far behind the curve Apple is when it comes to GPU power, HDMI and DisplayPort will have both been updated several times.

The discrete graphics chips in the MBPs support 4 or 6 displays.

Hah! Yeah, they might "support" it, but considering Apple uses low end parts, you're not going to get anything other than basic web browsing stale photo viewing out of it.

You'd have to go a step further and go SSD to SSD. Even SATA III SSDs aren't close to fully saturating USB 3.0 bandwidth. They're only currently around half that speed.

So as it is now, if you're going from the fastest SATA III SSD to another one, Thunderbolt offers absolutely no benefit over USB 3.0.

But USB 3.0 does offer the real world benefit of being available EVERYWHERE other than Apple computers.

Wow! Talk about owning someone!
 

Then how do you explain the multiple of sites that state otherwise saying the max resolution is by 2400 and not 2160?

http://www.ngohq.com/news/17076-vesa-introduces-displayport-1-2-a.html
http://nerdlogger.com/category/displayport/
DP 1.2 supports a maximum of 5.4Gbps per lane, with 4 lanes providing a whopping 21.6Gbps throughput, more than enough for 10-bit 4xHD resolution (3840×2160). To achieve the 21.6 Gbps rate, the per-lane data rate is doubled from 2.7 Gbps to 5.4 Gbps max, over the four lanes that exist in the standard cable. For a single display, this enables up to 3840 x 2400 maximum resolution at 60Hz, or a 3D display (120Hz) at 2560 x 1600.

[Cutting-edge integrated display support
DisplayPort 1.2
Max resolution: 3840x2400

There are multiple other sites that contradict what you claim. You claim a max resolution for 16:9 displays and mine is for 16:10 as well (which are still prevalent in many niches).
And, yet again, if DisplayPort 1.2 supported a DVDs worth of extra pixels over HDMI 1.4, why does it matter when there isn't a single Apple computer on the planet that could push that sort of resolution fluidly beyond basic text display?

Would that not also extend to hdmi in that case of no mac being able to push out the resolution fluidly? :cool:

Thank you for a sane analysis on this. I'm sure that when the prices on SSDs start to come down significantly HP will incorporate Thunderbolt.

We are skating where puck will be.
Quad-hd-displays can be just around the corner.
Retina displays are now in fashion and we are just waiting when this moves to bigger screens.
Doesn't change the fact that HDMI supports higher resolutions and has more features.
Doesn't matter, they are both pretty much in par with tech specs or what do mean by "features"?
Saying that dp's 49 Mbit/s for audio isn't enough sounds pretty funny?
Also dp can be (and many times are) "Dual-mode DisplayPort" when it includes hdmi.
DisplayPort was approved in May 2006, before HD DVD and blu-ray drives were available for PC.
First dp product arrived in 2008. First hdmi product arrived in 2003. Gigantic time gap. CE giants can't change interconnect standards every now and then. And when new option doesn't offer significant upgrade, they just neglect it.
IIRC big names had their whole tv lineup converted to hdmi just about when dp arrived.
They had no change to tell the customer that "Hdmi is the next great interconnect which you can use the whole year to future and then buy everything again with dp".
HDMI won because it is the better connector.
Hdmi won because it was way before and it has cheaper signalling method, not because it is somehow more advanced.
Maybe both are replaced by HDbaseT.
 
I'm sure that when the prices on SSDs start to come down significantly HP will incorporate Thunderbolt.
By the time when cheap consumer ssd's will saturate usb3 (2020?) there will be already usb4 coming, and so on...

It shouldn't be too hard even for fanboys to accept that nothing can stop usb.
It is simply ubiquitous. Just like power sockets, etc.
It will take dacedes to get it out of mainstream.

This is why all improvements should rely on backwards compability to usb and eg. external hard drives should connect logically with eSATAp. That way they have full advantage of real sata connection. And sony's idea of implementing tb to usb will also work.

PCWorld reports that while Hewlett-Packard (HP) had considered using Thunderbolt in its newest desktop PCs, for now it's sticking with USB 3.0.According to Lauwaert, everone seems to be content with USB 3.0 so they don't see the value of including Thunderbolt in their desktop machines.

[url=http://cdn.macrumors.com/article-new/2011/05/thunderbolt.jpg]Image

Thunderbolt is the high speed interconnect system that was introduced by Intel in February. Apple was the first customer to adopt the new connector with the launch of its early 2011 MacBook Pros. Apple has since released new iMacs also supporting Thunderbolt. Due to the newness of the connector, there is presently little 3rd party support, though Intel is said to be opening up Thunderbolt development this quarter.

HP is notable for being the largest U.S. computer manufacturer accounting for 26% of the market in the 1st quarter 2011.

Article Link: Hewlett Packard Not Convinced of the Value of Thunderbolt

I fail to see why it has to be a "one or the other" thing, why not support both? Especially on a desktop? I can see why they'd want to hold off for now, but making it be an issue versus USB 3 seems ridiculous.

Remember when mini displayport was supposed to be the next big thing?

Once again apple will trot out how they are setting an 'industry standard' when hardly anyone else uses it. Here we go again...

Uh, I've seen Dell laptops, and a plethora of video cards all come with MDP. I'd even go so far as to say that I see MDP more than I see DP and almost as often as I see VGA (on currently shipping machines, that is).

Thunderbolt has value as a backplane extender, even if noone else adopts it.

Desktop PCs arguably have a lot less use for it, as they are very easily expandable anyway. iMacs, laptops and other 'sealed' units will benefit most - particularly when the manufacturer (Apple!) chooses not to include other high speed ports like eSATA.

External Video cards? Lots of them? Lots of external video cards combined with lots of internal? Gajillion-way SLI/CrossFireX? A pipe-dream, I know, but still, when you put PCI-E on a port, a lot of previously impossible things become possible.

Well, by having 1-2 TB ports one would NOT need to have:
- VGA
- DVI
- HDMI
- DisplayPort
- eSATA
- ExpressCard

Just think about the reduced size and thickness. Isn't that alone an excellent reason?

That alone is actually a stupid reason unless you were talking about an ultra-portable. I don't need this port on my MacBook Pro to decrease thickness. I need it on my MacBook Pro to eliminate the need to ever own a desktop Mac ever again.

It sucks that the latest Macbook Pro could have had USB 3.0.
Instead we got Thunderbolt which you still can't use for anything.
If Apple wanted to include Thunderbolt so bad why did they not give us USB 3.0, too?

Apple won't adopt USB 3.0 until support is native in the chipset. Incidentally, this is supposedly coming with the chipsets designed to run Ivy Bridge. Same with Thunderbolt, if I'm not mistaken.

Sounds like a PC is the best choice for you! Apple should lower their prices?? Hey, so should Ferrari...... then they would sell like hot-cakes. We don't need that fast engine, speed limit is 65mph over here. Dump the big engine and lower the price. Thats the mentality correct? I'm glad Jobs is making the big decisions.

Apple uses logic boards with the same basic components that HP uses. Shocker, I know. And they're all made by Foxconn in China. The same cannot be said of Ferrari and its engines in comparison to normal people cars. At best, you pay for Apple's superior internal layout and chassis engineering, along with the privilage to run OS X, and even that is marked up. But hey, way to be exclusive and prove most anti-Mac-user sentiments correct! As a Mac user, I object, but what do I know, right?

When Apple starts including Thunderbolt on iPhones, iPads and iPods - allowing folks to sync in seconds - HP's machines will look like the junk they typically are.

They won't be prime candidates as they're not the type of devices that would even connect via PCI-E to use that kind of bandwidth anyway; or so I've been told. The idea of Thunderbolt on an iOS device sounds nice, but really, USB 3 is more likely to take that one.

Hopefully iOS Devices will soon go TB. This would boost TB a lot. For those who do not (yet) have it there should be an USB alternative.

Time Machine Backups are already mentioned. Why do I need SATA III with SSDs everywhere when my backup device is slowed down by the connector?

I think HP fears the licensing costs (other than Intel Motherboard vendors have to pay for it, or am I mistaken?) and want to put some pressure on Intel to lower its costs. This move seems to be a tactical one.

Mac User will use TB and everyone processing media is hoping industry adopts it. Just take a look at musicians who used FW800 to connect their recording equipment or movie makers with huge 1080p files.

There will be TB in future peripheral equipment and every Computer Tech Company who does not implement it will lose some margin to apple and those who have it.

It's a new port with no adoption, cut HP some slack and wait for it to actually prove its own mettle.

We should all be well aware by now that one thing Apple is TERRIBLE at is setting industry standards.

Firewire was a fail and only ever existed on Macs and a very, very select number of desktops.

DisplayPort hasn't even made it onto any non-Apple product

Thunderbolt so far exists on a small selection of Apple hardware with no clear push or motivation to getting it adopted wider. Apple should be meeting with the Dell's and HP's of the world - they are the only people that have the volume and power to force the standard into the industry.

Apple simply sucks at getting new ports onto computers, period.

You, sir, have no idea what you're talking about. Please go correct this matter and then come back to present your newly educated opinion.

What people and HP seem to be forgetting is this; Thunderbolt is an enabling technology as well because it clicks straight into the PCIe chipset which means that it is only a matter of time before someone makes a USB3 break out box that hooks straight into thunderbolt just as there are already ethernet and firewire adapters already (based on some quick searching). The point being is that in the future Apple can get rid of USB/Firewire/etc and just have a set of thunderbolt ports on the back and then sell the required adapters for those who need them thus drastically simplifying their motherboard designs.

As for HP, they've always been a has been of a company who does zero innovation - name the last innovative thing that came out of HP that didn't involve downloading a 300MB driver package or a piece of buggy bloatware that slows down the system and sprawls crap from one end of the hard disk to the other. HP quite frankly should be the very last company being asked when it comes to anything innovative or pushing the envelop.

While I know that it's cheating to cite their Palm division, but the stuff that they're doing with WebOS makes the things that Apple is doing with iOS seem boring and unimaginative by comparison.

Hope Thunderbolt doesn't end up like Mini DisplayPort: adopted by no one, compatible with nothing :D

Dell has started using miniDP on their laptops, and NVIDIA and ATI/AMD are using it on their video cards. Adopted by no one? Compatible with nothing? Behind the times much?

Do you think we will see Apple scrapping it's old docking connector on the iPhone, iPad and iPod touch, make a clean start and replace it with a single Thunderbolt connector?

So that, from next year, all Apple devices can connect to each other at the same high speed using this same new connector?

No. Nice idea though.

It requires a huge external controller on the motherboard, space that could have been better used by Apple for a discrete GPU in the 13" MBP or for an actual useful controller in the form of USB3.

A USB 3 controller, I'll grant you, but there's no way the space used by the Thunderbolt controller could be used for a discrete GPU on the 13" and really that's more likely than not due to heating requirements.

I find it funny that the resident Apple Fan boys are touting the benefits of the NEW hardly adopted connection, saying people need this and this is the future.

Those same people hammer google/microsoft/verizon/samsung/dell/hp for things they do that "doesnt really matter, or has no use"

NFC?
LTE?
Bluray?
Voice Recognition?

and so on... :rolleyes:

All of those technologies, Thunderbolt included with them, are "The Future", or at least vast improvements over present day tech. Will they succeed, I don't think anyone can safely say now; but make no mistake, they are all improvements.

One exclamation mark can easily make the point that you are a cheapskate who pays too much for his tech.

Kinda reminds me of this: http://theoatmeal.com/blog/apps

Not to pick on you...but why do people feel a need to substantiate their opinion (which by itself is always going to be subjective and bias) with a reference to professional life?

Perhaps Im conveying my own ignorance of what Biotech Engineers do everyday...but I dont think you fine folks at Umbrella represent the majority of electronic consumers;)

Resident Evil much? :p

The PC gaming market is still bigger than Apple's world wide market share, so PCs will continue to have a place significantly longer than Apple or Apple fans would like to have you believe.

And outside of the PC gaming market, theres plenty of people who still prefer a traditional desktop PC over anything else because of price, speed, and expandability. There isn't another device on the planet that can currently match a desktop PC in any of those ways.

Yeah, laptops are "more popular" and sell more than desktops, but only by a few percentage points. You're greatly overlooking the fact that desktop PCs still sell in the tens of millions every year and will continue to do so for years and years to come.

Really, Mac desktops are flawwed by design in a way that PC desktops aren't. The most optimal Mac to get IS a laptop. Why? Because the whole point of a Windows desktop is expansion and even on a Mac Pro, your expansion is limited. Not to mention the lack of SLI or CrossFireX. I can't upgrade the motherboard? I can't upgrade the CPUs without voiding the warranty? What kind of "desktop" is that? Yeah, I do get Xeons and that is rad. But I get a mid-range consumer video card at best.

At least Mac laptops are, Mac Pro aside, just as unupgradable (if not less so) than their iMac and Mac mini counterparts. And frankly, that's why I could see Mac users poo-pooing the idea of desktops; for their platform desktops make little sense unless you need storage and pre-Thunderbolt expansion.
 
little value for a "desktop"

I fail to see why it has to be a "one or the other" thing, why not support both? Especially on a desktop?

I see this from the other side of the coin - since a desktop already has PCIe slots and spare drive bays, what is the value of TBolt?

If HP introduced a new design of high end laptops without TBolt, I'd consider that lame. The user of a high end laptop is much more likely to want to connect to devices that cannot be inside the laptop.

On a price-sensitive commodity desktop, however - TBolt doesn't make sense now. When TBolt is on the Intel chipset, and adding TBolt means simply adding the connector on the bulkhead - then it would be silly not to support TBolt.

Today though, HP is making the right decision. Put the tiny NEC USB 3.0 controller on the system, and wait for TBolt to "sink or swim".

Apple's history: usb half slower than in pc's to promote macs & fw. No eSata on macs, even when chipsets support it.
So in that light, there's pretty good change that Apple will try to keep differentiating macs from other pc's by touting that they have TB, which is better than usb3, and therefore won't put usb3 in their macs even when chipset natively supports it. Otherwise users might notice that usb3 is cheaper and more usable.

"Good enough is good enough"

"perceived acceptability"


No wonder companies put out cheap rubbish and get away with it.

But HP's line has never been known for quality, either...

Somebody could say "Macs should run Windows because Windows is more usable" as well.

USB3 is faster than USB2, but thunderbolt is much faster than USB3.

Ideally, both would be nice. I see no reason to summarily nix USB3 from Macs, but each new USB is hampered by building on an old standard. Thunderbolt is a new standard.

(And just to make sure to preempt this tangent, Apple isn't going to move exclusively to ARM because ARM, for a number of applications (memory-intensive, 64-bit, etc), is inferior to Intel and those who know they need the power know what a "backwards step" is. I can see a purpose for lower-end Macs, yeah, but not high-end.)
 
In perspective....

USB3 is faster than USB2, but thunderbolt is much faster than USB3.

This would have been more objectively phrased as:
USB3 is much faster than USB2, but thunderbolt is much faster than USB3.

USB3.0 is about ten times faster than USB 2.0, but TBolt is only two times faster than USB 3.0.

Anyway, the only TBolt item that I've seen priced is $299 more than the same device without TBolt. (There are no TBolt items being sold today, and most of the "pre-announced" devices have not disclosed prices.)

The HP systems that didn't add TBolt are priced $299, $329 and $599.

Does anyone see any value in adding a port for which each device will cost from 50% to 100% of the price of the computer system or more? (If a TBolt connection costs $299, then a $100 USB disk drive with TBolt would be $399.)

The "TBolt tax" is going to make the "FireWire tax" seem like pennies.... That's the cost of going with a proprietary single-sourced port.

How can anyone who values "standards" embrace Thunderbolt? How can Apple talk about the value of standards (for example HTML5), and then ship systems with Thunderbolt? TBolt is "Apple's Flash".

Wrong. PCIe has almost no overhead, whereas USB's is at least 50%.

Links? Bandwidth overhead? CPU overhead? For which controllers?

It's dangerous to extrapolate worst case USB 1.1 issues to USB 3.0. Yesterday's demons can be exorcized from today's offerings.

Please show the 50% overhead in the following benchmark data:

image005.png
(click to enlarge)

When I look at that graph, it seems to show almost identical performance for chipset SATA, eSATA, and USB 3.0. Where's the 50% overhead?

Also note that nobody has announced or proposed TBolt disk drives. Everything that's been pre-announced is SATA disk drives on a PCIe-SATA bridge.

Because Thunderbolt will go the way of firewire unless it becomes popular and is used in a majority of computers.

It might be because the drive is too slow to start running into overhead problems. But that is an industry standard drive and what most consumers would buy, if there is no difference then all is well. No increases in speed would be seen if that drive used a Tbolt interface.

...
No increases in speed would be seen if that drive used a Tbolt interface.

And therefore almost nobody will pay a premium for TBolt, and it will go the way of FireWire.

By the way, it's interesting to see FireWire acknowledged as a failure on an Apple-centric board. Also interesting to see the acknowledgement that "nearly as fast, but a lot cheaper" is realized to be a killer proposition.

I doubt that TBolt will fail, but I also doubt that it will be common. It will be "that port that we can connect really expensive things to if we need a ton of bandwidth".
 
Ideally, both would be nice. I see no reason to summarily nix USB3 from Macs, but each new USB is hampered by building on an old standard. Thunderbolt is a new standard.
Yep,
a new standard that has already hampered displayport
and if hanging to it means there will be no usb3 in macs,
it has already hampered future macs.

I have 2 hdd's that use usb3 and both are way faster than any tb hdd, that does not even exist.
 
Those favouring USB3 over Thunderbolt are suffering from a lack of imagination.

Thunderbolt just isn't comparable. It's a much lower level interface, exposing PCIe - and therefore capable of acting as a transport for a lot of other interface types. It's more valuable in this usage than as its own interface standard (which I can't see it succeeding in).

For an expandable HP PC, I can't see the point of it. Any sort of expansion you need, you can put in a PCIe card and end up with eSATA, USB3, Fibrechannel etc.

On the Mac, unless you buy a MacPro, you're stuck with what Apple gives you, and you're also stuck with Apple's plan of forced obsolescence (no Firewire on the MBA, or the current MacBook).

Thunderbolt gives us both a much more flexible interface that's capable of supporting other standards, and also protects us from Apple's removal of Firewire. USB3 satisfies neither of these criteria.

I don't care if Thunderbolt peripherals are relatively expensive, or if the standard gains little traction outside the Apple world. It's still a worthwhile standard - precisely because Apple hardware is so locked down, and this circumvents that to provide much needed expansion possibilities. USB3 would not.
 
Yeah, I much prefer my electronics to be tangible than imaginary though. ;)

Whatever.

Show me a planned USB3 to external PCIe adapter.
Show me a USB3 to Firewire 800 adapter.
Show me a USB3 to Fiberchannel adapter.

That's what I mean by a lack of imagination. USB3 can't do most of these things.

USB3 will be fine for what it is. But it's not the flexible expansion standard that single-box Macs desperately need.

Show me TB anything, buyable today and received in 1-2 days shipping. ;)

I've covered what I think of TB. It's basically a solution in search of a problem. host-based storage (or Direct-Attached storage as some call it) has been dying for years. As for the rest of the "adapters", why would I want FC on a laptop ? And if in a server or workstation, why waste space on a dongle, when I can simply throw in a HBA card ?

Same for the other ports, why not just have the port there instead of YADA (Yet Another Dongle Adapter).

Sure, if I close my eyes and throw out any common sense and apply pixie dust, I can see it... glimmering in the distance...

Still a couple of months off.

But we've been waiting years for a decent high speed interface on single-box Macs... even consumer grade mechanical hard drives have been faster than FW800 for 3 or 4 years.

It's worthwhile waiting a few more months for something that solves all single-box expansion problems, not just a souped-up HDD connector.

Creative industries (especially motion picture) are super excited about FiberChannel support for iMacs. There's a big cost benefit right there (why have a MacPro, if you're using remote storage, and iMacs provide plenty of power).
