My math seems to be way different
1e9 / 45000= 22,222 cycles per playout

According to my math, that comes out to around 205 cycles per
playout move. Pretty damn good, I'd say.

I get
g++-4.1 35 kpps/GHz
g++-4.2 45 kpps/GHz
g++-4.3 40 kpps/GHz
I'm happy it's quite consistent on core2
I'm curious about 4.4 as well.
g++-4.4 45 kpps/GHz
package gcc-snapshot on ubuntu
$ /usr/lib/gcc-snapshot/bin/g++ --version
g++ (Ubuntu 20081024-0ubuntu1) 4.4.0 20081024 (experimental) [trunk
revision 141342]
so quite old.
