For most of those benchmarks,regardless if they are real or fake, the key thing is SIMD performance. Integer SIMD is handled also by the new FPU inside bulldozer. So this will be the key for good or bad reviews. If it doesn't beat K10 in single thread or poorly thread integer SIMD workloads,it may not get so favorable reviews. If it manages to do this it will be both faster and more efficient than K10,in both single thread and multi thread benchmarks. Now,how all these "leaks" correlate to real performance is anybody's guess. At least in single thread workloads,when both halves of the flexfp are working on one thread,Bulldozer should be faster than K10 at similar clock. We don't see this in any of the leaks. It is actually slower by 15-20%,which goes against what we know about its FPU.
