AMD has improved on their 45nm process to release 3.2GHz part at retail and it shows in our overclocking, hitting 4GHz with 1.55v. We wouldn't say this was 100% stable but 3.9GHz was much more so. For comparison, the 940 hit 3.9GHz top on high-end air.

We revised our power numbers and tested using only the onboard video of our 790GX. Idle numbers were taken 5 minutes into the Windows desktop, load stressed all cores under Valve's map creation benchmark. The Phenom II runs much faster yet also uses less power than the original Phenom.
