Re: Probably the biggest areas for NGMA related optimizations are in SIMD/streaming/FP type apps. A 3 GHz NGMA chip has a peak FP performance (both cores) of 24 DP or 48 SP GFLOP/s. There is no way most current apps are coded in a way that even begins to tap that potential. Even most scalar integer code out there is probably far from optimal for a four issue wide x86 chip with three integer units.
Hopefully, some optimized apps start showing up prior to K8L. It would be disappointing to have an untapped competitive advantage that gets neutralized by the competition as soon as developers start tapping it.
