This is a wonderful deep dive on what awaits us in a few long months.

For just the tip of the iceberg...

Compared to Nehalem, the Haswell core offers 4× the peak FLOPs, 3× the cache bandwidth, and nearly 2× the re-ordering window. Overall, we estimate that a Haswell core will offer around 10% greater performance for existing software, compared to Sandy Bridge. For workloads using the new extensions, the gains could be significantly higher. In theory, AVX2 and FMA can boost performance by 2×

Compared to Sandy? I hate percentages based on old tech and speculation.

So Haswell could be neutered and be a performer on another platform? 10% better than Sandy...how much is that compared to Qualcomm's latest a year ago?
