Page 2 of 2 According to Intel, "The move from 65nm to 45nm involves more than just a shrink of current chip designs. The processors include such additional features as new Intel Streaming SIMD Extensions 4 (SSE4), which are 47 new instructions that speed up workloads including video encoding for high-definition and photo manipulation, as well as key HPC and enterprise applications. Software vendors supporting the new SSE4 instruction set include Adobe, Microsoft and Symantec A fast divider roughly doubles the speed over previous generations for computations used in nearly all applications through a technique called Radix 16. The ability to divide instructions and commands faster increases a computer's performance. Intel has released a total of 16 new processors: • The Intel Core 2 Extreme QX9650 quad core desktop processor, is designed for games support. It features a larger L2 cache and support for new Intel SSE4 media instructions to "help bring desktop performance to 'extreme' new levels." • There are 15 server dual-core and quad-core 45nm Hi-k Intel Xeon processors. The 12 new quad-core chips boast clock speeds ranging from 2GHz up to 3.20GHz, with front side bus speeds (FSB) up to 1600MHz, and cache sizes of 12MB. The three new dual-core chips feature clock speeds of up to 3.40GHz, an FSB of up to 1600MHz, and cache sizes of 6MB. The 45nm Hi-k Intel Xeon processors are compatible with server platforms using the Intel 5000 chipset family. In addition, Intel is launching three platform solutions to support 45nm processors, including: - The Intel 5400 chipset-based platform (previously codenamed Stoakley) optimised for high-bandwidth applications such as high-performance computing; • The Intel 5100 memory controller hub chipset and Intel ICH-9R I/O controller (previously codenamed 'Cranberry Lake'). These are cost-optimised solutions that support either one or two processors and also provide reduced power consumption using native DDR2 memory. • The Intel 3200 chipset-based platform (previously codenamed 'Garlow') that is specifically designed for single-processor entry servers.{moscomment} |
