No Cheap Quad-Cores from Intel
Even though there are not a lot of single-core chips in Intel’s microprocessor lineup now, quad-core processors are not going to become really affordable soon enough.
After Intel introduces its new 45nm central processing units in January, 2008, the company will not cut pricing of its Intel Core 2 Quad below $266.
The fact that Intel has no plans to reduce pricing of its quad-core chips signals that the company feels itself comfortable selling products with four processing engines at price-points starting at $266 and expects no substantial competition from Advanced Micro Devices, who is struggling to deliver quad-core enthusiast-class chips in late 2007 and quad-core and tri-core desktop processors in Q1 2008.

The new Q9000-series/45nm microprocessors are projected to have greater instructions per clock (IPC) execution compared to today’s chips, which means that they will be faster and more efficient even at the same clock-speeds with the current generation chips.
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.
