Reversi Benchmark: AMD64 X2 vs INTEL CORE DUO vs OTHERS

This round we manage to get an Intel Core Duo 2.16GHz with Shared 2MB L2, Mac Book Pro, to benchmark. Thanks CopperBlue for contributing his laptop. How does it compare to AMD64 X2 4200+ (2.2GHz) with 2 x 512KB Private L2 which has almost the same clock speed? However, AMD64 X2 is able to run in both 32bit mode and 64bit mode, whereas Core Duo runs only 32bit mode. Does it matter?

Let's see the first benchmark xversi-c-benchmark-v0.1 which utilizes only one core.


Intel Core Duo 2.16GHz has slight advantage over AMD64 X2 4200+ in 32bit mode. Interestingly, AMD64 X2 running in 64bit mode boost up the performance almost by 2x. Itanium II with much lower clock speed is clearly out of the game.

What about the Parallel Reversi? Let's see the next benchmark xversi-java-parallel-benchmark-v0.1.


AMD64 X2 4200+ clearly has an advantage running in 64bit mode. The 64bit JVM definitely helps in boosting the performance. Hence, if you own a 64bit processor, use a 64bit OS, and 64bit components such as Sun Java for x86_64.
