The slides unveil the GPU of 2013 will embrace many features found in the CPU, five years from now GPUs are expected to have full support for C++, complete pointer support, adaptive workload partitioning, preemption and virtual pipeline.
Here are some performance figures, lots of tera figures here. NVIDIA expects a high-end GPU in 2013 will offer over 20 teraFLOPS of computing power, that's 20x as much as today.
GPU 2013:
Arbitrary dataflow General purpose programming model Special purpose hardware Hardware managed threading and pipelining Freely intermingle "graphics" & computation
