The major micro-architectural improvements for new Intel Core 2 processors, besides SSE4 instruction set, include the so-called Unique Super Shuffle Engine and Radix 16 technique. The Super Shuffle Engine is a full-width, single-pass shuffle unit that is 128-bits wide, which can perform full-width shuffles in a single cycle. This significantly improves performance for SSE2, SSE3 and SSE4 instructions that have shuffle-like operations such as pack, unpack and wider packed shifts. This feature will increase performance for content creation, imaging, video and high-performance computing. Radix 16 technique, according to Intel, roughly doubles the divider speed over previous generations for computations used in nearly all applications. In addition, Intel also improved virtualization technology as well as added some features to dynamic acceleration technology, which is supposed to boost single-threaded applications’ performance on multi-core chips.

Will these 'improvements' increase the throughput of PRIME95?

Super Shuffle will be a minor help. I use shuffle operations at beginning and end of FFT pass 2.

SSE4 has a new round instruction that may provide a small benefit once I buy a quad-core machine and write some new assembly code.
