A few highlights from the talk:Multiple primitive pipelines for setup, etc.
Real caching in L1, L2, separate color/z caches for graphics and atomics
Concurrent tasks
Out of order resource allocation
ECC on srams and drams
Shaders
No vliw, just multiple issue simd
Branch, scalar, vector, vector memory, export units
4x16 wide vector ALUs Some of the GPGPU improvements include:
1. Real caches
2. Graphs of data parallel kernels
3. Exceptions, recursion, function calls
4. Better branching, predication, masking, control flow
5. No more VLIW, instead a scalar+vector arch with fewer scheduling rules and more regular code generation
6. Acquire/release consistency model
7. ECC support for some SKUs
8. Substantially better DP performance for some SKUs
9. Faster global atomics
