Does anyone know exactly what SIMD intructions were sped up how in Core Duo, I've been waiting for the Processor Optimization manual, but data on the Core Duo was not released last month or this month. I guess all will be revealed in time, but what are the reported improvements to multimedia processing instructions supposed to be?
Core Duo is a dual core PIII with 2 extra pipeline stage and more cache, the same optimization guide you used for PIII you can use with Core Duo/Solo, but Duo is dual core, search for SMP otimizations.
