The performance will be less than a 1MB Athlon-64, of course, probably by about 2 to 3 speed
grades (of .2 GHz in this case). But then, the smaller chip area may allow a higher clock speed to
gain back some of those speed grades.

Why would you think that? Only a very badly designed processor would have a speed path
affected by L2 cache capacity. Don't bring up heat, a 256 KB A64 would probably burn
more power than a 1024 KB A64 because it will be accessing memory nearly twice as
frequently on average.
