A Three-Way AMD Opteron Server
Abdul tips a thin little review up at The Inquirer of the Themis Slice. "The Slice is a three socket Opteron machine with two PCIe slots and two Infiniband 4x ports... Why would you want three sockets rather than four? Easy, latency. Any CPU in a 3S system is one hop away from any other CPU. In a 4S system, you can be two hops away. This adds latency, and more importantly, you take a big hit on cache coherency latency. This kills performance."
You don't need a million dollars. I know Microsoft is a rip-off, but 1 million for the Xbox 360? Don't think so... But then again they use PowerPC CPUs.
