ATI Radeon HD 4870 X2 – Idle mode
ATI Radeon HD 4870 X2 – Under Loading
Here are the infrared pictures of a Radeon HD 4870 X2 and a GeForce GTX 285. In idle mode, we can see that one of Radeon two GPUs is hotter than the other. Maybe the second is better cooled or the first does a little bit more work (displays Windows desktop…).

The GeForce GTX 295 has an efficient cooling system and manages to keep the temperature lower than the Radeon.
To heat up both graphics cards, the author of these pictures has used the pixel shader test of 3DMark06 in loop mode. I’m curious to see the same test with FurMark 😉
