To some extent Fermi looks like more of the same, only bigger and faster.

What's really interesting about it is that they've added L1 and L2 cache, they've gone to a global memory model so you can pass pointers around and they've put some effort into making branches less expensive. I didn't yet spot whether it supports recursion, but it's implied that it does. I expect to see a lot more GPU-raytracing projects start popping up in the near future thanks to this...

I'd be very interested to see how this compares to Larrabee, if/when it actually comes out.

There's a pile more information on nvidia's site for fermi at http://www.nvidia.com/object/fermi_architecture.html

The big change is certainly the support for indirect jump instructions and the exception handling support. Quite a big leap in GPU programmability. The only piece still missing is fully coherent caches.

Good find.
