Benchmark Configuration | |
CPU Load | Prime95 v25.8. 64-bit executable, Small FFTs, Eight Threads |
GPU Load | FurMark 1.6.5 Stability Test, 1920x1200, 4x AA |
Combined Load | Prime95 (Seven CPU Threads) plus FurMark (One CPU Thread) |
Assembled for an upcoming overclocking article, our test system pulls 407 W under Prime95, 676W under FurMark, and 870W with both programs running at full force. FurMark requires one dedicated CPU thread to reach full GPU load.
Less-aggressive overclockers can get similar power consumption at far lower clock speeds using higher-cost hardware, such as Intel’s Core i7-980X processor and a pair of Nvidia’s GeForce GTX 580 graphics cards.
