More proof that Conroe is a one trick pony: cache
Now, we have the most direct comparison of the Core 2 and K8 microarchitecture.
DailyTech tested the Conroe-L, which is a single core Conroe with 512KB of cache. The Conroe-L 440 is rated at 2GHZ. Comparing to Athlon 64 3500+ (2.2GHZ, 512KB L2), the Conroe-L is definitely an undedog.
As you can see from the gaming benchmarks, the Conroe-L trails Athlon 64 in all tests. In one game, the Conroe-L is 13% slower. Clearly, the inherent average IPC advantage of Core 2 over K8 in desktop environment is less than 10%. I pointed out this long long time ago.
As we have seen previously, the 3GHZ Opteron frags the 3GHZ Woodcrest in both integer and floating point peformance.
K10 will simply kill Core 2.
PS: those who compare the prices of Conroe-L and Athlon 64 must note that Conroe-L is a future Intel chip no one has seen in the wild yet.
