I bet today's technology can do this...
What you'll need is... I dunno... 16 of those new "two GPUs on a card" Radeons (I can never remember the model names - too many, too fast) in a box.
And some arcane graphics libary to replace DirectX so you can use it on a more parallel system- I hear SGI has some left over from the good old days of Onyx 3000
and there you go, you've got yourself a box that can handle 50,000+ poly characters.
And don't forget the custom motherboard with multiple PCIe links, you don't want 16 graphics cards, 32 GPUs sharing a puny x16 link... And having eight or more CPUs to feed the hungry GPUs with data would be a good idea too... and lots of RAM, like 512 GB - remember its only 20 or so sticks of RAM with MetaRAM!
Of course, people will then complain that its noisy, uses too much power, is to big (becuase everyone knows that the Macbook Air is the future, right?), too expensive and so on...
What have I been drinking?
C. P. U. Its not a big processor... Its a series of pipes!
