This is not what I see; for me and Pachi, i7 performs about 15% faster
than Core2 in single thread. This is "Q9300 @ 2.50GHz" vs. "i7 920 @
2.67GHz" so the clock difference certainly is not the sole reason.
Pachi:
[i7] 2.3kpps
[core2] 1.9kpps
I also just did a quick test with latest libego:
[i7]
27.2497 kpps
10.2013 kpps/GHz (clock independent)
[core2]
23.043 kpps
9.26901 kpps/GHz (clock independent)
...and Erik's ancient libego build:
[i7]
Performance:
1000000 playouts
7.69283 seconds
129.991 kpps
[core2]
Performance:
1000000 playouts
8.46945 seconds
118.071 kpps
