So... A somewhat unbalanced OoO design (gshare predictor, only 96 physical regs), a pair of massive vector units, tiny total caches per core (1MB is fine as an L2, but in the absence of a dedicated L3 it's awfully small unless 32+ cores are inactive, isn't it?), clock targets that can politely be described as optimistic, and a memory interface far slower than those present in GPUs in a similar FLOPS range?
What am I missing?
