What does "low-ASP" mean? by: Anonymous on 12/7/2009
This is a great article. Very informative. It may be that I am too much of a software guy, but what does the term "low-ASP" mean with regards to hardware?

I am guessing "average selling price"?

Thanks for the clarification.
RE: LRB by: Theo Valich on 12/5/2009
Unfortunately for Intel, the worst case scenario in this analysis came true - the company had no other choice but to cancel the consumer version of the product.

We will closely follow what develops afterwards and future products that may come of project LRB.

" Both have drivers that will take Intel years to catch up with, and in that time AMD and NVIDIA will not be sleeping. How long until NVIDIA release a quad-core 2GHz ARM A9 chip with 1TFLOPS integrated graphics? "

Don't think we'll saw nVidia 1TFlops integrated graphic anytime soon, well not based on ARM Cortex chips i hope cause they wanna go with 250mW chips per core and then some 100W TDP "integrated monster" from envy doesn't seem to have any sense.

And as far as driver goes Intel at least had enough money to buy time to wrote _some drivers_ when they could afford to publish crappy integrated graphic chip w/o proprietary firmware in case of Imagenation Tech just to avoid ImaTech make some money on their chipsets. Poor job intel but pople *bought it* unfortunately for them ... marketing done a great job promoting Craptom chip to pay out for intel tick-tock rapid node development


btw. this article carries out a lot of misinformation :)(


[I]"ATI's Radeon 5870 GPU comes with [B]160KB of L1 cache, 160KB [/B]of Scratch cache and 512KB of L2 cache. The L1 cache features a bandwidth of around 1TB/s, while L1 to L2 cache bandwidth is 435GB/s. This flat out destroys any CPU cache bandwidth figures, and we're talking about a chip that works at "only" 850 MHz. "[/I]

What GPU he's really talking about that's numbers for rv770 so called HD4870 just MHz frequency doesn't add up :cool:
While oth rv870/Cypress has 32 L1 + 32 scratch per 16 SIMD core x20 came out as 640kb L1 and 640kb scratch!! And about L2 cache hasn't rv770 have much more L2 cache up to few MB as the wise speculations on die shot weer telling? And rv870at least has a double amount of that L2 cache if it's really rv770 x2 w/ dxx11 compliance on single die


[I]"AMD [B]Sexa-Core Shanghai[/B] = [B]640KB L1[/B] [64KB Instruction + 64KB Data per core]"[/I]

And just a line above it he successfully do the math for Quad core :wink: And last time i hear a news from AMD hexa-core D0 revision is called [B]Istanbul[/B]


[I]"Intel [B]Sexa-Core Dunnington = 96KB L1[/B] [16KB Instruction + 16KB Data per core]"[/I]

Theo, directly copy-pasted this reliable info from Wikipedia source
[IMG]http://imageshack.dk/imagesfree/2Bi09043.png[/IMG]

And as far as i know Dunnington is 45nm Penryn based CPU and Penryn had 32kB(L1I)+32kb(L1D) cache. Thus giving also 64kbL1 total x6= 384kB L1 on all six cores. ntm if 16kB is true then the number is 192kB and not 96kB (130nm Northwood already had 12kb+12kb L1 cache :grin:)
terrible writing by: Anonymous on 11/3/2009
Could you possibly babble any more? Quite possibly the most poorly written article I have ever read.
it's the factories ... by: Anonymous on 10/21/2009
Craig Barrett was all about building more factories ... the idea being to compete and win, no matter what, with manufacturing might, not design brillance. He succeeded and that's what Intel is today. Time will tell if it was/is a winning move.

The Larrabee project is in deep shit: delay after delay, lackluster rasterizing performance, extreme power hungry. By the time it will be out, Nvidia's GPUs will beat it in rasterizing and raytracing performance (Fermi's architecture with caches, atomic ops and divergent threads benefits raytracing much more than GT200).
128-bit by: Michael A. McKenney on 10/14/2009
We don't even have much in the way of 64-bit software. Office 64-bit is scary enough. Office 128-bit is a nightmare worthy of film. I don't see what the fuss is. I just want more CAD and A/V apps to go 64-bit so I can work on larger projects in 16-24GB of RAM.
Linux drivers by: Anonymous on 10/13/2009
The only reason I will buy larabee is for its linux drivers, I lost count of how many times i've had to reinstall or switch back to windows 7 because the nvidia driver screwed up my X server... I havent had a single problem with the intel drivers on my Acer Aspire one. Intel: give me a stable driver that performs decently (equilivalent to a 8800gt) for ubuntu and I will buy.
Another Itanium by: Anonymous on 10/13/2009
At it's worse Larrabee might be stuck in the niche Super computer department just like it's overhyped forerunner Itanium.

It all depends on how much Intel has invested in the project to make this work.
If it's good but it costs many dollars of investments and also costs many dollars to produce I won't think we'll see an affordable mainstream version of this anytime soon with performance to match it's competitors.

And in the meantime both AMD and Nvidia won't sit still either.
re by: Anonymous on 10/13/2009
"I just don´t understand why Intel did´t try to buy Nvidia before/instead of investing so much money on Larrabee... "

I remember reading a rumor about Nvidia being aproached by Intel for a buyout years ago but Nvidia wasn't interested.

"The BIG problem is creating a x86 GPU. That was the hellishly idiot decision that they imposed... "

I was wondering the exact same thing too when I heard about the LRB concept.

The big problem isn't building a GPU. Intel can build a GPU with time, and could easily buy someone who makes GPUs.

The BIG problem is creating a x86 GPU. That was the hellishly idiot decision that they imposed...
S*** on me by: Anonymous on 10/13/2009
Thanks God, Buddha, Allah and all the other deities for not being in that mess anymore.
How much money did those f*ckers earned at Braunschweig? My salary was half that.

Let us hope that the end of X86 proprietary architecture is coming soon; the whole concept evolved today in an obstacle for the progress.

The end of this concept will have profound changes on the OS systems, especially Windows.
Failabee by: Anonymous on 10/13/2009
I thought that the Imagination/PowerVR SGX535 was only used in the GMA500, which is itself only used within the Paulsbo chipset for Atom. Of course, I don't know why they didn't use a cut-down variant of the current Intel Integrated Graphics (which as far as I know are not based in any form upon Imagination/PowerVR technology) - presumably it takes up too much die space or uses too much power.

Aside from that, the article is perfectly reasonable and explains the train wreck that is Larrabee. Hopefully it will put things in perspective for a lot of Intel hypebots.

Problem for Intel is that AMD have a 2.7TFLOPS board out now (HD5870), a 3TFLOPS chip out soon (HD5890), and an X2 product that could get 6TFLOPS, never mind the 32nm/28nm product out in a year's time with their new GPU architecture (4-5TFLOPS per chip?). NVIDIA aren't hurting for FLOPS either, with excellent DP figures for Fermi. Both have drivers that will take Intel years to catch up with, and in that time AMD and NVIDIA will not be sleeping. How long until NVIDIA release a quad-core 2GHz ARM A9 chip with 1TFLOPS integrated graphics?
Great article! by: Anonymous on 10/13/2009

That is a great article! Very interesting to read.

I just don´t understand why Intel did´t try to buy Nvidia before/instead of investing so much money on Larrabee...
Itanium by: Anonymous on 10/13/2009
This overhype of a phantom product already happened before with the Itanium.
The CPU to end all CPUs in the mid 1990s.

People believed the hype.
and as a result some companies went belly up after waiting for the final product.
(SGI)

LRB hype reminded me of the Itanium hype about a decade ago.
Hopefully this time people are wiser.
Dear me. by: Anonymous on 10/13/2009
There are so many factual errors in the referenced to Imagination Technologies, PowerVR and the relationship between Intel and Imagination it is hard to view the rest of the article without a severely jaundiced eye.

If there's one thing to Intel fangirls is their religious fanatism, stupendus loyalty and inherent fascism. Global Domination, x86 Everywhere, etc etc. We got Microsoft, we certainly dont want another hardware dictator around.

If there's one thing that can unite ATI and Nvidia fanboys it is the mutual hatred of Larrabee
by: Anonymous on 10/12/2009
LRB is Intels Netburst GPU. Still they havent learned their lessons, it will be their downfall.
by: Anonymous on 10/12/2009
Damn Theo, you summed it up pretty well.

Let's hope Intel learns their lesson and gets a more competent team on the Larrabee.
