Sorry for the serial posts, but I wanted to break them up a little bit at least...

Can Intel and AAPL really balance the gap between power saving and CPU power? I mean with lithium-ion battery, this is the main obstacle? just

like the laptop speed can't have a breakthrough without resolving the hardrive speed problem

Well, Intel actually does a good job by making all kinds of different power/performance combinations available. The real problem is how Apple "chooses" hardware for you. I guess I am just used to the PC market where I can get whatever I want. I mean If Apple were more flexible with customization, you could order a new macbook with a low power processor, like a:
Core 2 Duo SL940: 1.86Ghz Penryn - 6MB L2 - 17W TDP

It's similar to the chip in the Air, but based on Penryn. Versus the normal 25 watt or 34 watt chips in the MB/MB Pro, It would definitely get better battery life. Even so, Nehalem is more efficient than Penryn and is supposed to have new power optimizations and lower power states. Also, it will really reduce the amount of L2 cache, which I'm sure eats a lot of power. Wikipedia says 30% less power use for Nehalem compared to Penryn.

Since the mobile versions of Nehalem won't have an IMC, won't this update be yet another average 10-15% speed bump as has been the norm?
I get that there are refinements in the arch that will help encoding, probably something similar to the Yonah -> Merom upgrade, but can anyone with more knowledge

explain why Nehalem would be such a meaningful upgrade to MB/MBP users?

Mobile Nehalem does have an IMC, it only doesn't have quickpath. There will be *native* one-die quad cores chips and it also brings support for DDR3 SDRAM, SSE4.2,
and SMT/2 threads per core. In short, It's a new microarchitecture with major improvements, and part of it's primary focus is on improving real-world performance from the previous generation. I would be very disappointed if Merom->Nehalem were to be anything like Yonah->Merom.



Frequent worthless upgrades really. The one thing I never see on this forum are people touting how blazingly fast their new Penryn is after waiting

for sooooooo long then they buy and do not report numbers.
It's really a waste for Apple to allow Intel to dictate their upgrade cycles.

Worthless? Why would people tout how much faster their Penryn processor is? Most of the improvements were in power efficiency, and the primary increase in performance (up to 45%) comes when software updates are made available that support SSE4.1, which are not out for the majority of benefitting applications AFAIK.


Someday (in my copious free time) I'll take an architecture class and find out what the heck you people are talking about with all this low level hardware stuff.

Nah, you don't need a hardware class. I followed all this computer hardware nonsense closely when I was younger and only recently jumped back in before the release of Core Duo "Yonah". All you need is the internet. Between Wikipedia, Arstechnica archives, and Anandtech, I've learned everything I know... alas, you will waste a LOT of time on this stuff. It get's quite addicting, just like macrumors :) :) :)


As someone else also up-thread pointed out, Apple doesn't introduce a product and then incrementally reduce the price on it. A friend of mine and I were actually talking about this very thing a few weeks ago, and at that time (since I really don't pay any attention to PC computer vendors, their products or business practices) I didn't realize this was the case. But yes, lo and behold, this is how things are. But not in Steve Jobs land. Nope, you introduce a product and keep selling it at the same price, month after month, quarter after quarter, even though your volume-discount wholesale prices drop like a stone. Great strategy for Apple, but a really lousy one for us, their customers....

Yeah, as you said, Apple does have a large design/R&D budget and software budget and they do sell their OS for a decent price, but at the same time they limit the amount of hardware options and stick to a pretty narrow spectrum of hardware for efficiency. Couple this when their always premium hardware prices, and I don't think it's an excuse. In fact, it really pisses me off that so many hardware-naive consumers end up getting so ripped off from Apple when they buy hardware late in the cycle. The more I think about it, the more I can't believe that they don't even discount hardware that is ancient in PC terms. They could at least reduce prices by a couple of hundred dollars or replace the oldest components. I mean how long did we see the Mac Pro with only a geforce 7300 or Radion X1900? The Radeon card was outdated when it was introduced!

I think Apple enthusiasts should do everything they can to discourage buyers from buying computers from apple after the first 4-5 months after introduction without seeing a price reduction. Consumers giving in to this crap is the only reason it continues. People should demand more.
 
Montevina has built-in GigE according to MacRumors own Intel Mobile Chip Roadmap.

Yep, I saw that.

I have a different question. I usually know my stuff, but I'm not sure about this one, and I looked it up on wikipedia, and I still can't find the answer.

Do the current and past Centrino platforms actually specify/include an ethernet LAN controller? Or is Montevina's built-in GigE the first time a Centrino has included one?

I assume they always have because Centrino specifies an Intel motherboard, and I assume the ethernet chip is built right into the motherboard. My current Laptop, a Core Duo from Dell (~mid 2006) has a Centrino sticker, but the 10/100 LAN identifies in Windows as a Broadcom chip. Is this just because Intel uses a broadcom chip on the motherboard?

I've looked at Wikipedia, Intel's Centrino site, Arstechnica, etc and NONE of them mention ethernet/LAN as part of Centrino. But thats just because its supposed to be implicit, right?
 
Ok so let me get this straight. In the desktop/server Nehalem, the processors use QP to connect to each other and to connect to the Tylersburg I/O hub, which is a replacement for the "memory controller/northbridge". The Tylersburg I/O chip connects to the PCIexpress controller/slots and also connects using DMI to the ICH (southbridge) for usb/networking/etc.

That all makes sense. Now in the laptop architecture, you say there is no need for a northbridge (as the memory controller is now integrated) and thus no need for quickpath; and that the PCI express controller is built into the processor as well. So basically, you are saying that there is no need for a laptop equivalent of "Tylersburg I/O Hub"? If i'm following this right, the consequences of this are as followins:

1) mobile Nehalem connects directly to the PCI express slot (and expresscard) using it's integrated PCI express controller.
2) mobile Nehalem connects directly to the southbridge (ICH) using DMI
3) mobile Nehalem connects directly to a bank of RAM using onboard memory controller.

Am i right? and by the way, what is the interface that connects the on-chip memory controller to the actual SDRAM slots?
Actually, from my understanding of the slides, Intel isn't putting the memory controller on die. They specifically say on package (see page 7) for the dual core desktop and mobile processors.

and Thank god Apple doesn't do the whole Centrino. Even with Santa Rosa, INTEL STILL HAS 10/100 ETHERNET CHIPS! Thats right folks, Go customize a brand new Dell Inspiron --- 10/100 NIC is all you get!

Hasn't Apple had 1000/GigE standard for like 2-3 years now?
Yeah that was my bad, I keep forgetting that Intel isn't doing LAN yet. Even so, I would think Apple wouldn't use it anyways. I still base it on Apple not using Intel WiFi. But it is possible that I could be wrong. I really would like to know if larrabee will be ready for mobile use. I am curious to see if Intel followed down AMD/ATI footsteps.

...
The memory controller is "on package" for the DUAL core desktop and mobile Nehalem processors, called Havendale and Auburndale, which also have integrated graphics cores. The QUAD core Nehalem processors, including Clarksfield mobile processor, have the memory controller on die.

That's what I get from both page 7 and from the Nehalem Wikipedia:

http://en.wikipedia.org/wiki/Nehalem_(microarchitecture)

I believe this is right for the Clarksfield mobile Nehalem processor. The wikipedia link above says Clarksfield has dual channel DDR3.

Right, I wasn't talking about the Quads or the server CPU's as they all have it on die.
I am pretty sure the CPU's won't have Larrabee integrated in them. Especially since Larrabee alone is supposed to have a 150W TDP.

Yup.

Wow I thought I was looking in a mirror for a second. Been reading tech stuff since I first got the internet and wanted to know the specs on a computer I was about to buy. Bam found Anandtech and Toms Hardware (which was 100x better back in the day) and accidently got hooked on reading about mhz and the #s of tech...Then I started to dig deeper and read more and discovered roadmaps and codenames and got HOOOOOOKED.

Yet to own a mac, but always been an avid reader of macrumors (my tech thirst wasnt biased I followed the G4, G5 etc), just recently started to chime in on the forums...

ah... the old tomshardware.. I totally agree, it was MUCH better back in the day. I used to spend hours and hours on websites like that.
Funny thing, I still remember being back in junior high and waiting for months and months for my pre-ordered 3Dfx Voodoo 2 graphics card to be released. I honestly think I was failing all my classes at one point from spending all my time reading forums! :) :) good times..
 
Wait didn't intel just come out with penryn so how can they so quicly come out with a new processor.
Won't this eventually make penryn obsolete faster!!
and we haven't even seen that many computer adopt this new technology yet!!

Because that is what Intel does. Plus they are trying to make sure Shanghai doesn't catch on.

There is a rule if you want to run a successful business: Someone will make your stuff obsolete. You will be more successful if _you_ make your stuff obsolete, before your competitors do. Many companies that were leaders in their field died or lost significantly because they didn't listen to this rule and tried to prevent progress from happening, until someone else took over.
 



On Tuesday, Intel provided the first official information about the Nehalem microarchitecture -- the successor to the Core microarchitecture. Intel plans on phasing out the Core microarchitecture starting in late 2008 with the introduction of Nehalem-based server processors. Laptop and desktop processors based on Nehalem are not expected until 2009.

Kinda new to understanding this but does this mean that the 8 cores out now will basically be junk?

Thanks Laz

Well the 8 core systems out now use two 4 core chips. But those won't necessarily be obsolete. Processors fail less frequently than most types of hardware (ie hard drives and video cards). There are government servers that use non-core architecture chips. Until the hardware you currently have cannot perform the tasks you need it to perform, there's no real reason to upgrade your system. Its mainly the individual consumer that tries to keep up with the latest in technology. So the word junk is kinda relative.

I wonder if some professional artists really worked on their g4 powerbooks. I got a 1.5 (2004?)and I've never used it for serious work since it's too slow from the get go. I use it now for safari but it was always that way since I first got it. always worked on desktop cpu.... so for me, it was always "junk" and is good to "wow" your friends for it's cool design.

tho with newer macbooks, it's a different story... based on the reviews, I think they are real workhorses and I can't wait for the new case design:)

Yes, some professional artists do work on their very old G4 1GHz PB's with only 4 GB's of RAM. I use PS, Illustrator, Dreamweaver, Sketchup, Nikon Capture Editor, work with RAW/NEF files, and numerous other programs. I usually have a minimum of 7 programs always open. Do I see the spinning wheel more than I'd like? Yes. Does my PB feel zippy? No. Is the PB "junk"? No.

I can't wait to update MBP sometime this summer. Same with my printer. And the same with my Airport Extreme and Airport Express. However, all have served me very well in my life as an artist. And my old PB is the definition of a work horse.

I guess I should've spent more money on ram during that time....(it was pricey then)... Macbook Pro 2.0 here I come!!!!:)
 
I am so with you on this one!!! :)

cool! honestly, I was very tempted to buy the recent penryn macbooks but patience is a virtue so I will wait....:) a 5 year old design, even if real cool is still a 5 year old design... hehe...

I need to ask you, what is it like owning a 17 inch? are you still planning to get a 17? I'm used to having 15s but since I plan on making this my all around pc, might as well get the giant 17 right?

The 17" PB is my only computer and I constantly travel with it. I love the 17" because of the larger screen as I do a lot of visual apps work on it often when I'm not home. What I don't like is the weight. And I know some people on the forum say it's not so heavy, but I'm always traveling with art supplies, cameras, external HD, and other peripherals like clothing and a toothbrush, lol.

If I thought it would work for me, I would buy a MBP 15" to cut down on weight (actually I wish I could just get away with owning a MBA), but I won't. My next will also be a 17" - I just hope it's slimmed down a bit (without losing the superdrive and firewire).

Thanks for the insight, man... honestly, even the 15 incher is already heavy for me to be carried around in meetings and such. (and I'm not a wimp:).... hehehe....

BTW, You are an awesome artist, bro! nice site you got there:)
