Intel Harpertown är den kommande den processor som föra Intels serversegment in i 45nm-eran. Harpertown är en quad-core-processor som blivit optimerad för enkel- och tvåsocketsystem. I övrigt är den väldigt lik Yorkfield i sina ytliga specifikatione, t.ex. 1333MHz FSB. Harpertown är dock byggd för att arbeta tillsammans med Intels server/workstation-styrkretsar Intel 5000/5100, men det som är riktigt intressant är att Intel kommer att återinföra DDR2-stöd med billigare servrar. X-bit labs har kommit över lite mer information om den kommande processorn, medan vi också fått veta att Intel kommer med stor sannolikhet ha (minst) ett Harpertown-system redo under Computex.

"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."
