Ok,from what I read at AT live blog, Haswell will be a beast of a chip. Th thing can do 2x256bit load and 1x256bit store per cycle per core. It can do 8ops per cycle in execution units and it can do 2x256bit FMA ops per cycle per core. It also can do 1 read from L2 per cycle which is double of what IB can do. In every respect,power,performance and perf./watt this chip will be a marvel. I'm impressed.
As for AMD,I'm sad to say this but no matter how good the SR core is and no matter how much it improves over BD core(even the mythical 45% that vr-zone claims) ,it will be probably crushed by Haswell. Intel just widened the gap in SSE/AVX workloads to more than 2x and I have no clue how can a SR based Opteron(even with 24-28 cores!) chip even start to compete with 10-14 core Haswell in HPC workloads. The gap will be massive I'm afraid. Kudos to intel.
