well, 5870 = 6950 <= 7850, which is still on par with the best mobile graphics cards

If you get 70% gaming performance with that flexibility, not bad

If performance is really a concern, the next-generation Mac Pro with dual FirePro is the choice

To me the point of using an external graphics card is to get desktop class graphics performance from your notebook when it is docked at your desk. Now for me if I was going that route I would want to use a GTX 780 which is incredibly bottlenecked at PCIe 2.0 4x speeds (16Gb/s) and would be bottlenecked at Thunderbolt 2.

And we need to remember that 20Gb/s is the total Thunderbolt 2 bandwidth. So if you're using such a setup you're sacrificing connectivity. Perhaps you have another dock you want to use that offers Ethernet which the MacBook Pro lacks or perhaps a RAID enclosure. The point is you're using up all your bandwidth just for one card.

I know that the Retina MacBook Pro does technically have two Thunderbolt ports but from what I understand Thunderbolt 2 simply takes the 2x 10Gb bandwidth in the Thunderbolt IC and combines them in to one physical connector when a Thunderbolt 2 device is present. So it would appear at first glance that even a Retina MacBook Pro with two Thunderbolt ports could only make use of one port when using a Thunderbolt 2 external graphics chassis.

And finally we have the concern that Apple may stick with Thunderbolt 1 and bandwidth only at 10Gb/s or that chassis only ship at Thunderbolt 1. It has been a number of years since Thunderbolt was introduced and the amount of accessories available is still quite small and most of them still very expensive.
 
ehehe what about a second graphic chip from intel in crossfire that only works wen needed? that certainly would blown away any nvidia or amd discrete card
 
...and there it is. The death of the Pro in MacBook Pro. So Apple can continue their irrational obsession with stripping functionality to make thinner and thinner.

R.I.P.

Please elaborate.
If integrated graphics gets you from A to B as fast if not faster than discrete graphics then what difference does it make?

Or do you measure the size of your penis by computer specs?
 
No, the Iris Pro is far behind the GT 650. For example, go read Anandtech. I remember you from the forums, where this was already presented to you. I guess you are the ignorant one, buddy.

ok.....

Anyways, the only applications said article tested were GAMES and GAMES ARE NOT VERY "pro". :rolleyes:
 
I agree with you 100% on your sentiments. I simply wanted to add that, while obviously the subject matter should be the primary concern of the student, for me at least, I like having the latest-and-greatest machine for school. It's definitely overkill but I feel compelled to buy something nice. This is why, this past december, I bought an almost fully loaded $3,400 retina mbp for school whether i need the horse power or not.

I equate it to the same reason people live in nyc and buy ferraris. You're certainly not going to do 200 down 2nd avenue but it's nice to know the horsepower is there when you need it.

My advice: You're heading off to school - focus like a madman on the subject matter, and not on the machine.

University tuition is astronomically overpriced as it is (thanks to the fact it's subsidized and considered "mandatory"), so use the resources they have on campus.

I always found that those that focused on technology and having "the latest and greatest" - and I was in that group - didn't do nearly as well as those who focused on the core foundation of their field. (I wasn't too bad there either, but I definitely got distracted by always trying to apply the latest technology.)

For your means, any MacBook made in the last 2 years should do fine. If you're in engineering, get a big screen and/or an external monitor (which are dirt cheap). And study, study, study!

Thats like buying a god damn power drill for a screw that you need to tighten.

Its your money, but why would you burn cash like this lol
 
More Memory + 17" retina display

What is the point to set 2560x1600 on 15"? 2560x1600 on 17" makes more sense.
What is the point to name it a pro if the max. memory is only 16GB?
 
so, we get MBP with a substandard GPU as apple lose the Nvidia/Ati discrete graphics card to save weight/power consumption/cost AND they charge a premium for it ?
 
If Apple drops Dedicated Graphics (with its own dedicated RAM) they should also drop the word 'Pro' from the name and call it Macbook Casual Consumer
Better still... people should wise up and stop reading too much into marketing jargon. I think you can buy "pro" toothpaste these days.
 
Don't expect a thunderbolt-based HD7970 or even GTX Titan. But for a desktop-level card like HD7770, it should be fine

The HD7770 requires 16X lane width, but according to that thread, you can only have 8X unless it somehow works with two cables.

----------

That guy is essentially wrong. Modern GPUs don't tend to saturate pci-e 16x and they certainly don't "require" it, the old mac pro doesn't support 16x links on each of it's slots, they're 16x physically but only play with a limited number of lanes.

Thunderbolt has plenty of bandwidth to give a significant graphics performance boost, is it less than a desktop pci-e 3.0 16x slot? sure, does it matter? not really.

OK, makes sense.
 
Hang on. Why is everybody writing off dGPU for 15"? The main issue with the retinas was the 13" had an HD4000 and that it just wasn't powerful enough to drive the resolution.

Who's to say this piece of news isn't related to 13" only? Given that Apple worked with Blizzard to get Diablo 3 retinafied on the 15", I really doubt they're going to take a step back on the dGPU for the 15".

I say 13" retina with 5200 and 15" still gets a dGPU

Also the 15" would still have two gpus so the auto switching would still happen when your on battery. Apple is ignorant but they're not stupid.

I know that the Retina MacBook Pro does technically have two Thunderbolt ports but from what I understand Thunderbolt 2 simply takes the 2x 10Gb bandwidth in the Thunderbolt IC and combines them in to one physical connector when a Thunderbolt 2 device is present. So it would appear at first glance that even a Retina MacBook Pro with two Thunderbolt ports could only make use of one port when using a Thunderbolt 2 external graphics chassis.

…

Each TB 1 port has 2 10 Gbps channels. TB 2 just combines these two channels into 1 channel with an effective bandwidth of 20 Gbps.
The load on one port won't affect the load on another port.
 
Apple like always is investing in technology "in the spring" of it. Broadwell will be 40% faster than Iris Pro, and the chips from Skylake(DDR4 which is GDDR5) will bring power that is 2 times of broadwells. That can bring it to the range of... GTX680MX.

Impossible? Well we thought the same about Iris Pro.

Im pretty sure that none of AMD's and Nvidias chips will get even close to the power of future graphics from Intel at that TDP. The bigger - we know the result. But im sure to 40W TDP, Intel will blow anything in the market.

From what I understand that is only 10Gb in each direction. To combine both of them would only be 20Gb in one direction.
 
I myself have opinion. I didn't buy it (i go for 15" rMBP) & people who ask me which mac they should buy I didn't recommended rMBP 13"..

& Please don't ask for source .. I read it & don't bookmark every thing .. i have other things to do in life..

+ i am a Graphic designer /animator /programmer / tech .. so if you spend 1500+ $ and didn't get powerful PC .. then whats the point .. i am not stupid to buy what ever apple release
I'm a "creative guy" too. I do photography (with Photoshop), video capture/editing (FCPX), website design/engineering and iOS development. Having had a shot at doing such tasks on the 13" RMBP, it's absolutely capable of running all of my tasks very smoothly. The ONLY reason I want the 15" display is because it's bigger, not because it's more capable.

There's a very, very big difference in what suits you, and what suites anyone else. Just because the 13" RMBP doesn't meet YOUR needs, it doesn't mean it doesn't fit someone else's needs, and it certainly does NOT imply that the sales are any less.

And I don't run out and buy every Apple product there is. My current MacBook Pro was purchased in December 2010, and only now just starting to fall behind my needs. My iMac, purchased in 2011 takes everything I throw at it. I only bought my iPhone 5 last year because my contract was up, and was due a renewal. My only "had to buy it now" purchase was the 3rd Gen Apple TV, and I've used it pretty much every day since I bought it.

Don't judge people based on nothing. You're always wrong.
 
My Late 2008 Unibody MBP has a discreet GPU. It requires you to log off and back on to use it, and it makes the fans spin at 6000 rpm non-stop, while the computer performs slightly better at a very small number of things. Battery life also drops by 2 hours immediately. Since I never bothered switching to it, except a couple of times, I didn't notice that mine was faulty right from the start, and kernel panicked about once every 1-2 weeks. Noticed when it was too late, out of warranty, so I've never really used it.

So yeah, if there's no nVidia chips in my computer, I won't mind!

Less things in a computer = less things that can fail.
 
I agree 100% with you and do realize that this is blatent & unnecessary overkill but i still do it. i like showing off too and im honest enough to admit that i am ONE OF THOSE PEOPLE.

I dont do this with everything but mostly with tech. Also the reason i always but the newest iphone and only the 64gb model... even though i have 30+ gigs free on it at all times :-x haha

ps - the samsung 840 = FIRE. i use only intel ssd's but appreciate the samsung 840 series.

Thats like buying a god damn power drill for a screw that you need to tighten.

Its your money, but why would you burn cash like this lol

What is the point to name it a pro if the max. memory is only 16GB?

Because 16GB RAM on a LAPTOP is good enough for most people ("power users"). Users that need more than 16GB also realize they need a better CPU as well which is why they go for a desktop instead of a laptop. the rMBP with 16gb ram is good enough for the 95% of power users out there, IMO. Everyone else realizes that if this doesn't meet their needs, the next step is to move up to a desktop/imac/mac pro.
 
but who care's if the new graphics are integrated? if are more fast than the current NON integrated, who cares? integrated or non integrated the point is that is more fast than the actual.

(Im non an export, so maybe my comment is very stupid, but YOU GOT my point)
 
Well, this pretty much clears up the question about whether or not there will be a dGPU in the Haswell rMBP.

I mean, if this new "Super Iris Pro" can at least match, or outperform, the 650M, then we are looking at a serious increase in battery life. I would also have to think that eliminating having to switch between two GPUs will also be an advantage. Then again, the 650M is old tech, so this thing will really need to be equivalent to a modern dGPU to avoid pissing everyone off. Also, what happens to the extra space now that there is no dGPU? Bigger battery? More RAM?

This is definitely interesting. I just hope to hell that this isn't only for the 15", and that both the 13" and 15" will get a version of these processors.

I can't see them taking discrete graphics away from the high end MacBooks... but if they want to drop the non-retinia MacBooks having the 13" have the max horsepower possible in the 13" version will help salvage that image from the first round that weren't spectacular.

----------

It'a mistake to drop the dGPU. Iris Pro, special version or not, will never be as good... And Intel will never catch up with Nvidia. They have really nice Logan cards coming next. People who want real graphics performance, including decent gaming, will be left behind if they buy MacBook Pro's.

except Intel is using patent power to keep nvidia from releasing an integrated GPU chipset... so using Nvidia means you have to jump through multi-chip solutions with an external GPU. that kills battery life dead because intel makes it inefficient.
