AMD Six-Core Opteron Microprocessors
AMD announced today in AMD Opteron Upgrade Program that it will start shipping its six-core Opterons, codenamed Istanbul, in May this year.
AMD’s six-core Opteron processors code-named Istanbul feature 6MB of L3 cache, dual-channel DDR2 memory controller and are compatible with socket F infrastructure. The only tangible improvement over the quad-core Shanghai processors that the Istanbul chips have is HyperTransport Assist feature, which works the same way as Intel’s snoop filter inside high-end chipsets for Intel Xeon processors.
In addition to Istanbul is that it is a drop in replacement for existing Opteron based systems. Since the chip utilizes Socket F, the only other items Istanbul will require to be an upgrade is that the system supports split power planes and a BIOS update.
The new AMD Opteron processor will provide a fast upgrade path to improve performance and energy efficiency within the data center without needing to replace and buy entirely new systems1.
