The really new trendâ€"the one that just recently began and that will only accelerateâ€"is the increasing presence of game-oriented hardware on the list. At the top of the list is IBM's Roadrunner, which first rode the power of the Cell chip to the top spot in June. Roadrunner epitomizes both trends in that it combines a modified version of the processor used in the PlayStation 3 with AMD's Opteron. But the Cell isn't the only coprocessor on the list that has its roots in gaming.

An NVIDIA GPU has finally made its way onto the Top 500 list, in a 170 TFLOP machine based at the Tokyo Institute of Technology. The TSUBAME was upgraded recently with NVIDIA's Tesla S1070, a math coprocessor that's essentially a specialized version of the same GPU that the company sells to gamers. Like its gaming sibling, the Telsa is programmable with CUDA, and when paired with a general-purpose processor, it makes for a great, data-parallel, floating-point machine

yea, it's more for parallel processing

What do you think graphics processing is?

but it's not primarily used for graphics processing on the PS3 is it...

read this yesterday and hooray for IBM being number one again.

Just because it's not normally used for gaming doesn't mean it shouldn't be. If anything you'd think CPU's should be more like GPU's. In the aspect of parallel processing that is.
They should be able to calculate simultaneously the physics, game AI and whatever you're doing in the game without batting an eye. The video card has to spit out all of those pixels at the same time and it's very hard for a CPU to do something similar to that.

data dependencies are parallelism's worst nightmare and there are a lot of them in gaming.

heck, most things us end users do have high amounts of dependencies(unless we're running multiple apps)

there's a reason why intel, AMD, IBM and others always focused on single threaded performance. Multicore architectures are a last resort. In the past we could add 10% more silicon and double the clock speed and all would be well, that is no longer happening, silicon is reaching its limit.

I wish the cell WAS PS3's GPU instead of CPU.

Or that PS3 was a single processing machine like PS2 was. PS2 was just one giant video card.

It's quite clear that Cell is more powerful than Xenon both in theory and practice gaming and otherwise, so the flamers can go ahead and shut up now.

I have always loved the cell processor. I hope PS4 comes with even a better version of Cell or pherhaps TWO cell clusters. One for CPU and the other for GPU. Although I guess coding for it is hard enough lol.
