Introduction Introduction Introduction Introduction
AMD's latest Quad-Core AMD Opteron processors are designed on a 65mn process technology and features new core
enhancements, including 128-bit large data bus supplying the Floating Point units, SSE4A advanced instructions, and support for
dual-channel DDR2. The architecture also features improved branch prediction and three levels of memory cache as opposed to the
two levels of cache on the Quad-Core Opteron, including 64 KB dedicated L1 cache per core, 512 KB dedicated L2 cache per
core, and 2 MB of shared L3 cache between all four cores. The Quad-Core AMD Opteron 2300 series also supports Link
unganging, doubled max sustained CPU-CPU data bandwidth in xw9400 at 16GB/s full duplex, thanks to xw9400's dual-HT link
architecture.
NOTE: NOTE: NOTE: NOTE: Quad-Core AMD Opteron processors offer 1 GHz HyperTransport™ interconnects.
