>>Fermi has a 384-bit GDDR5 memory interface and 512 cores. That’s more than twice the processing power of GT200 but, just like RV870 (Cypress), it’s not twice the memory bandwidth.<<
And Vista will still be a dog on it.
Sort of brings up the question, if something sucks with a lot of power, does it blow?
***********************EXCERPT***************************
When matched with the right algorithms and programming efforts, GPU computing can provide some real speedups. Much of Fermi's architecture is designed to improve performance in these HPC and other GPU compute applications.
Ever since G80, NVIDIA has been on this path to bring GPU computing to reality. I rarely get the opportunity to get a non-marketing answer out of NVIDIA, but in talking to Jonah Alben (VP of GPU Engineering) I had an unusually frank discussion.
From the outside, G80 looks to be a GPU architected for compute. Internally, NVIDIA viewed it as an opportunistic way to enable more general purpose computing on its GPUs. The transition to a unified shader architecture gave NVIDIA the chance to, relatively easily, turn G80 into more than just a GPU. NVIDIA viewed GPU computing as a future strength for the company, so G80 led a dual life. Awesome graphics chip by day, the foundation for CUDA by night.
To describe VISTA I will quote Bart Simpson “I didnt think it was physically possible, but this sucks and blows at the same time”
same for Microsoft Office with the new ‘ribbon’ bar that takes up 1/3 of your screen with commands you never use, and moves all the commands somewhere that you can’t find them
