CPUs ... why are they so far behind?

post #1 of 24
Thread Starter 
I read this on wikipedia today, and if it isn't totally true, let it at least start a conversation.

Quote:
General purpose GPU

NVIDIA has created the Compute Unified Device Architecture (CUDA) technology. This is an interface for the GeForce 8 cards that provides general purpose functionality for the processors within the GPU, which is a developing technique, known more generically as General Purpose GPU (GPGPU). With regards to performance in the general purpose computing realm, the NVIDIA GeForce 8800 GTX provides up to 197 times the performance of an Intel Core 2 Duo E6700 dual-core processor [5].
This makes me think about something I've been thinking for a long time. Why are CPU's so far behind GPU's?

I know that GPU's ar leaps and bounds ahead of any CPU, but just, why? Now that AMD has ATI up their sleeve, why won't they slap an old radeon gpu onto an x86 chip? I'm willing to bet my x1950xt can perform more highly than a kentsfield. It's common knowledge. I don't understand why a single GPU is able to perform so much greater than any quad-core we have right now. Is x86 that much of a limitation? Is there some conspiracy? Can GPU's not do the work CPU's are required to do?


Just a thought.

P.S.

http://en.wikipedia.org/wiki/GeForce_8_Series

That is where I read this. After the paragraph quoted, it explains a little what I'm wondering, but still ... couldn't these problems be ironed out with a bit of work? It looks like Nvidia is already doing this, in fact.

I would be pleased to see Nvidia or ATi throw in a surprise entry to the CPU market and blow away anything we've seen or speculated of so far.

This is not true, if it was nVidia would have already released a Processor that is ~2000 faster than a Core 2 Duo.

Obviously, if it was easy, it would have been done already.

I know there are technical terms... but GPUs are better at one thing, and CPUs are better at another (wow how vague haha!)

Anyway, I have seen a thread like this before. It has something to do with the type of data they move. Someone with more knowledge will come in and explain soon hehe

Something about flops, and, uh, textures, and uh, bits...

Probably because the applications the two cores utilize are different. CPUs need to be able to adapt to different applications, and programs, and what not. GPUs do one thing. Render graphics. So they don't have to be so wide-range
'bout time.

GPUs and CPU's do different functions (like adding or multiplying) so you can't really compare them or make the gpu do the work of a cpu (and vice-versa)

GPU's seem capable of much more than rendering graphics, though. New GPU's are able to process sound, and physics, and many GPU's can be used for folding.

like the others said. Conroes are general purpose processors and GPUs are specialists. GPUs are great number crunchers for folding, but that doesn't mean they would have to depth to do all the things we ask of them in daily use.

"Also limiting is the fact that G80's stream processors are not capable of performing well with nearly as wide of a range of instructions as a general purpose CPU"

gpu's are very specific in what they can process. cranking out the framerates for a very specific set of code (directx usually) doesn't take a full set of instructions and thus can be severely optimised for doing just what directx needs it to do. Pretty much any type of processing unit will be able to do basic math, which is what the GPGPU does. nvidia just created a way for people to be able to use that math power through their gpu's. That's why it's only used for crunching numbers and such...very basic stuff.
