K10 performance estimates
INQ had some rough numbers. On SPECint_rate_2006, a 2.3GHZ K10 is 21% faster than a 2.66GHZ Clovertown. On SPECfp_rate_2006, the 2.3GHZ K10 is 50% faster than a 2.66GHZ Clovertown.
These numbers translates to 40% IPC advantage in integer and 73% IPC advantage in FP performance.
I expect at 4P level, the 2GHZ K10 should be close to Intel's 2.93GHZ quad in integer performance and will be 50% faster than the Intel 2.93GHZ quad in floating point.
