[b3d] The future of the CPU-GPU war

post #1 of 17
Thread Starter 
Quote:
After a fairly standard review of CPU development over the last thirty years, a serpent is detected in the CPU boys' garden of eden, threatening their supremacy. "CPU profit margins are decreasing. GPU margins are increasing." As the old saying goes, "Follow the money!" and you'll rarely be lead astray. But where has this serpent come from?

Intel will make it so that you don't need two separate processors for rendering and general purpose with Larrabee.

hopefully that will be good for midrange and low end computing

but at least for now, i see the CPU/GPU war continuing for enthusiasts for some time.

Yeah usually a CPU is good for 2 years but a GPU cant go that far in order to max games and they are easy to upgrade.

One of larrabee engineers said that when they launch the discrete parts, that it will be 'high-end.' Not really reassuring since hes an Intel fanboy but it should be interesting anyway.

Not at all. Larrabee will be with reduced instruction set of x86, thus not a good decision of general purpose computing. It will be mostly strong in SIMD instructions.
A good thing is that it can be incorporated in CPU die and you can have CPU+GPU in a single package. But won't be soon, more like 2010.

The reason they choose x86 architecture for Larrabee is because x86 is common instruction set, and already there have been software renderers in games prior to Quake 2, Half-life 1. And Intel already has experience with x86.

Larrabee is GPU, despite it's Pentium 1 nature, It will be GPU, and can't work as CPU.

I thought that was what I was saying I heard we were getting a CPU+GPU on-die in fall 2009 with westmere or something.

I also hear that Intel is trying to pitch Larrabee to MSFT to use in the next Xbox as a CPU+GPU all in one package.

Do you honestly think Intel will take over the GPU market anytime soon? Judging by what Intel has done for the GPU world so far, I don't think Intel will be moving in on the high-end GPU market anytime soon.

Larrabee is still a dedicated video card. AMD Fusion will put the GPU on the CPU
