I admit, my 'evidence' is only anecdotal. I used to have an iMac core2 with 2 Ghz. Then I got a MacPro with 2.8Ghz two years later (two years ago). That one was about 50%-60% faster per core, which is marginally faster than the clock-speed implies. Now I have a spanking new iMac with a 2.66 Ghz i5 at work, which is the same speed as the 2.8Ghz MacPro. I don't have a computer with an i7 in it, so I can't say anything about how it performs with respect to the computers I worked with the past few years. But unless the i7 is dramatically faster than the i5, I haven't seen much progress over the past four years. But even if the i7 is twice as fast as a Core2, as you say, it took four years to get there. And it was not four years ago when Lukasz reported his numbers. When I look at published benchmark tests, the MacPro should be more than three times faster than the Core2 iMac. But my own benchmarks for several Go-related tests don't show that at all. In that case I go with my own numbers, instead of some published pie in the sky. If an Intel i7 can do 200K playouts, let's show it. :) Should be relatively easy to verify. Anyone have an i7? >The strongest programs have the slowest playouts :-) I don't know if that's exactly true. But we were discussing light playouts. We all know that that by itself does not give the strongest program.
