You can check it out over here.The Core 2's IPC is about 5-10% higher than the K8 for our set of games. The K8 has 20% fewer uops per instruction than the Core 2 for our set of games. The Core 2's branch predictors are vastly more accurate, with about 50% fewer mispredicted branches per instruction retired for our set of games. The Core 2's instruction cache is slightly more effective, with ~20% fewer misses per instruction retired for our set of games. Misaligned instructions are very infrequent for both CPUs - approximately one out of every thousand retired instructions is a misaligned memory access for our set of games. 60% of x86 instructions access memory for our set of games. The K8's L1D cache is more effective, with about 20% fewer misses per instruction retired for our set of games. The Core 2 Duo's L2 cache is much more effective, with about 50% fewer misses per instruction retired for our set of games.

Real World Technologies has written an indepth analysis of the performance and efficiency of Intel's Core 2 and AMD's K8 architecture. The hardware they tested is relatively old, but the article may still be pretty interesting for some of you. Here's a quick summary of their conclusions:
