Just for kicks : Bobcat's performance in superpi and wprime. This is a mind experiment since bobcat can't reach this clock,but bulldozer can be clocked down to 1.6Ghz.
1.6Ghz Bobcat in super pi gets a score of 49s => 4.2Ghz should get ~18.7s
1.6Ghz Bobcat in wprime (2 thread/cores) gets a score of 72.1s => 4.2Ghz should get ~55s in single core test
So 4.2Ghz Bulldozer core which in single thread workload such as super pi has 128bit fmac on its disposal is slower than Bobcat @ 4.2Ghz by 6% and in wprime is faster by 6%. Bobcat has 64bit FPU. It does look weird. So even if someone has a hardware that posts those scores (real hardware,not faking benchmarks),it may not be final platform.
