Barence writes "A senior vice president of Nvidia has denied rumours that the company is planning an entry into the x86 CPU market. Speaking to PC Pro, Chris Malachowsky, another co-founder and senior vice president, was unequivocal. 'That's not our business,' he insisted. 'It's not our business to build a CPU. We're a visual computing company, and I think the reason we've survived the other 35 companies who were making graphics at the start is that we've stayed focused.' He also pointed out that such a move would expose the company to fierce competition. 'Are we likely to build a CPU and take out Intel?' he asked. 'I don't think so, given their thirty-year head start and billions and billions of dollars invested in it. I think staying focused is our best strategy.' He was also dismissive of the threat from Intel's Larrabee architecture, following Nvidia's chief architect calling it a 'GPU from 2006' at the weekend."

Technology: Nvidia Claims Intel's Larrabee Is "a GPU From 2006" 278 comments
Barence sends this excerpt from PC Pro:
"Nvidia has delivered a scathing criticism of Intel's Larrabee, dismissing the multi-core CPU/GPU as wishful thinking — while admitting it needs to catch up with AMD's current Radeon graphics cards. 'Intel is not a stupid company,' conceded John Mottram, chief architect for the company's GT200 core. 'They've put a lot of people behind this, so clearly they believe it's viable. But the products on our roadmap are competitive to this thing as they've painted it. And the reality is going to fall short of the optimistic way they've painted it. As [blogger and CPU architect] Peter Glaskowsky said, the "large" Larrabee in 2010 will have roughly the same performance as a 2006 GPU from Nvidia or ATI.' Speaking ahead of the opening of the annual NVISION expo on Monday, he also admitted Nvidia 'underestimated ATI with respect to their product.'"

x86 rumors origin ? (Score:4, Interesting)
Currently nVidia is partnering with VIA for small form factor x86 boxes. And they have made several presentation about a combination of (VIA's) x86-64 Issaiah and (their own) embed GeForce.
Touting that the platform would be the first small form factor able to sustain Vista in all DX10 and full Aero glory.
Maybe that is where some journalist got mixed and where all this "nVidia is preparing a x86 chip" rumor began ?

This is what happens when technical information is filtered through the brain of a salesperson, manager, or executive. It comes out completely mangled on the opposite side or, even worse, it morphs into something which while technically correct is NOT the information that the non-technical person thought they were conveying (i.e. they have unknowingly modified the requirements specification in a way that is logically consistent from a technical standpoint, but will result in the wrong product being built).

Anyone Surprised? (Score:5, Interesting)
Is anyone actually surprised that the CEO is denying this? Even if the rumors were true, letting news out to market about it would give Intel time to prepare a response (and legal action).
Re:Anyone Surprised? (Score:5, Insightful)
Not at all. As you say, he would have denied it even if NVidia WAS planning a CPU. What actually speaks volumes IMHO, is the vehemence with which he denied it. Any CEO who's cover-denying a market move is not going to close his own doors by stating that the company could never make it in that space. He would give far weaker reasons so that when the announcement comes the market will still react favorably to their new product.
In other words: stick a fork in it, because this bit of tabloid reporting is dead.

I don't get the legal action part. Is the x86 architecture patented by Intel? Even if it is, wouldn't the patent have expired by now? After all, its more than 30 years old. Do AMD, VIA etc. pay licensing fees to Intel for building processors using the x86 architecture? If so, why cant NVidia?
Yes. Various pieces of parts of the x86 architecture that have been developed within the last 20 years (noteably, stuff related to the IA32 architecture of the 386, 486 and Pentium and later lines) are all still under patent.
Patents filed before June 8, 1995 get the greater of 17 past the patent grant date or 20 years total, whichever is greater.

Reprogrammable GPU? (Score:5, Interesting)
Difficult (Score:4, Informative)
Microcode-upgrade are possible for CPU that have a huge big complex reprogrammable pipeline like the current top of the line CPUs, or CPU where the pipeline is handled in software (like the Transmeta chips).
GPU, on the other hand, have a very short and simplistic pipeline which is hard-fixed. They draw their tremendous performance, from the fact that this pipeline drives ultra-wide SIMD units which process a fuck-load of identical threads in parallel.
But there nothing much you could reprogramm currently. Most of the die is just huge cache, huge registry files, and a crazy amount of parallel floating point ADD/MUL blocks for the SIMD. The pipeline is completely lost amid the rest.
(Whereas on CPU, even if the cache dwarfs the other structure, there are quite complex logic blocks dedicated to instruction fetching and decoding).

Let me guess: you've never read anything about microprocessor engineering, have you ?
What you describe is what every non-engineer dreams of. You want a chip that any idiot can reprogram, without knowing the "less simple" ways of FPGAs. That's kind of like saying you want a car that gets 200 miles to the gallon, can park in a shoebox and carry 20 kids in the back seat - oh, and it drives itself automagically so your kids can take themselves to soccer practice without bugging you.
The reason why no one ever builds such monstrosities is because there is simply no point to it, when you can have purpose-built chips designed and fabbed for a fraction of the cost. People don't stop breathing just because their device needs 2 distinct chips instead of one jesus-truck.

Who said price is the most interesting issue? I'd definitely choose the versatility of an open-source microcode GPU that could be dynamically reprogrammed to have any of several different instruction sets.
As long as they're Turing complete, any of them can in principle do anything. Yes, then at least to me it comes down to price - if it's cheaper to have a car, boat and plane than making a tranasformer that can do all three at it, suck at all three and cost a bajillion more I'll go for traditional chips, thank you very much.

Transmeta tried that. It was slow, expensive, and inconsistent. Also, nobody ever used any other 'instruction sets' besides x86, mostly because that's the most-common-denominator in the computing world.
It sucks, it's not the -best- way to do it, but it's the way the market seems to favor. Just ask Apple, Sun, DEC, and HP.

"A GPU from 2006" sounds a lot like famous last words.
I wonder if anyone at DEC made comments in a similar vein about Intel CPUs, when the Alpha was so far ahead of anything Intel was making? NVidia's architect should not underestimate Intel, if he does, he does it at his company's peril.
Re:From 2006 (Score:4, Interesting)
The alpha failed because the motherboards were $1300.00 and the processors were $2600.00 nobody in their right mind bought the stuff when you could get Intel motherboards for $400 and processors for $800.00 (dual proc boards, high end processors)
DEC died because they could not scale up to what the intel side was doing. you had thousands of motherboards made per hour for Intel with maybe 4 a day for Alpha. It's game over at that point.
I loved the Alphas, I had a dual alpha motherboard running windows NT it rocked as a server.

How nVidia "Survived" (Score:5, Insightful)
3DFx was the first company to publish Open Source 3D drivers for their 3D cards. nVidia sued them, then bought them at a discount, and shut down the operation. So, we had no Open Source 3D for another 5 years.
That's not "staying focused". It's being a predator.

What on earth are you talking about? 3DFx died because it was horribly mismanaged and ran out of money. There were lawsuits, but 3dfx sued NV first in 1998 and then in 2000 NV counter-sued (source [bluesnews.com]). True NV's countersuit was right before 3dfx died, but a simple lawsuit that's gone nowhere in the courts yet doesn't cause a company to go bankrupt overnight.
Personally I'll believe one of my (ex-3dfx Austin) friend's explanation for their downfall: the fully stocked Tequila bar that was free to all employees. Or there's a whole list of problems leading to their decline on wikipedia [wikipedia.org].

3dfx's problem was they could never figure out how they sold their cards. they flipped flopped from themselves to having others make the cards like Nvidia does. after so many times no one wants anything to do with you because it's bad for business planning.
nvidia has had it's current selling model for 10 years and only its partners have changed. if you want to sell video cards you can trust that if you sell cards based on nvidia's chips they won't pull the rug out from under you next year and decide to sell the cards themselves

How is a "GPU" different from a "CPU"?
The GPU is a specialized (vector) processor, while the CPU is a general purpose one. What the GPU does, it does great. But its reach ends pretty much there.
The nVidia is programmed with a specific higher-order assembly language, We rely solely on the hardware vendor for tools. I think that this is UNIQUE in the (mass-market) processor world. And this is why Intel, with an x86 compatible GPU is such a threat.
You're confused. Intel is not working on a "x86 GPU". Intel is working on a new GPU design - the kicker being that this is a relatively high performance one, instead of the kind of GPUs they offered so far (feature packed, but lacking in performance). The x86 instruction set has nothing to do with it, and in fact, has nothing to do with GPU programming, which is a completely different beast.
Can anyone else produce an OpenGL shader compiler for the nVidia? Or, better yet, extend it to do NON-shader tasks. How about for the AMD?
If i'm no mistaken, nVidias CG compiler is now open sourced. So yes.
