| AMD Athlon64 "Venice" May Low Power be with you! | |

DOOM3
What about real games? We used DOOM3 to look at the CPU power during the opening trailer and in the second iteration of Demo1. For comparison, we also show the frame rates achineved in Demo1 at low quality 640 x 480 pixels resolution.
Power consumption during the lead-in trailer and a run of Demo1 compared to the average frame rate: The Venice core-based 3800+ has the lowest power consumption and is coming in as close runner-up to the 4000+ taking first place. Note that, everything else being equal, the Venice core is about 4% faster than the Newcastle
The Ultimate Power Hog: Prime95
We ran a gazillion benchmarks that all showed more or less the same pattern but who cares anyway. What we were interested in, though, was what benchmark would beat up the CPU most - one might have guessed, it is Prime95 TortureTest.
Power dissipation values taken immediately after starting Prime95 and during the 4th iteration of the Lucas-Lehman tests, some 6 minutes into Prime95. Even though the difference to e.g. 3DMark'05 is not huge, Prime95 is and remains the one application with the overall highest load on the CPU as shown by the power numbers.
