Power Consumption and Temperatures
Power Consumption & Temperatures
The Phenom II processor tested today has a respectable TDP (peak wattage) of 125 Watts. Today's test setup used uses an ASUS M4A88TD-V EVO/USB3 motherboard on which we seated a dedicated graphics card (Radeon HD 5870), you'll notice that the end-result overall for idle and peak wattage remains good.
Have a look below to see how we measure and traumatize the processor. As you can see, once we stress all CPU cores with Prime95 (stress test).
We notice our test platform peak out at roughly 190 Watts power consumption when we stress the six CPU cores of the Phenom II X6. Our system idles under 100 Watts depending on the OS energy saving setting. This is a complete PC with a high-end graphics card inserted (GPU isn't being stressed).
CPU + R5870 | IDLE (Balanced) | Idle (High perf) | 100% CPU |
890FX + Athlon II X4 645 | 73 | 88 | 152 |
890GX + X4 965 | 75 | 96 | 164 |
890FX + X4 970 | 81 | 92 | 175 |
890FX + X6 1055T | 85 | 104 | 183 |
890FX + X6 1075T | 87 | 109 | 182 |
890FX + X6 1095T | 87 | 107 | 187 |
890GX + X6 1095T | 87 | 108 | 188 |
H55 +Core i7 870 | 115 | 170 | 218 |
X58 + Core i7 980X | 139 | 150 | 272 |
When we place a couple of platforms in a chart and look at peak power consumption, we see the Phenom II X6 1100T BE push onwards to 188 Watts when fully stressed, not bad really. Let's put the processor under heavy load and see how temperatures behave as well. BTW bear in mind that these tests are all very motherboard dependant and results can (and will) vary from PC to PC.
Processor temperatures while idle remain below 30 Degrees C / 86 F based on air cooling the processors. We are cooling the processor with an OCZ Vendetta heatpipe based cooler only. Very mainstream cooling and very cheap.
Peak temperatures remain really good as well, the temperatures of the Phenom II X6 1100T processor are just phenomenal at under 45 Degrees C CPU and even lower measured per core on the coretemp. Let's go the next page and see where we end with our overclock.
