AMD Fires Back at Intel with 6-Core Opteron

AMD Socket F (1207) Opteron owners have reason to rejoice, as it looks like the chip maker's upcoming Istanbul chip is on target for a 2H 2009 release and won't require any new hardware. A 6-core chip built on a 45nm manufacturing process with 6MB of L3 cache, Istanbul will go head-to-head with Intel's 6-core Dunnington-based Xeon released in September 2008. AMD had some heavy criticism for Dunnington following its release, saying it's just a glued together triple-dual core processor with 50 percent more cores than the quad-core and costing 50 percent more, among other complaints. We'll have to wait for Istanbul's release to see how it stacks up against Intel's 6-core solution, but in the meantime, AMD did demonstrate a 24-core Istanbul configuration pitted against a 16-core Shanghai rig using the same parts, both with HyperTransport 3 enabled. With 50 percent more cores, the Istanbul machine produced almost double the bandwidth at 42,000 MB/s versus 25,000 MB/s for the Shanghai setup. No ... (link)
