ATI Radeon HD 4850 Versus NVIDIA GeForce 9800 GTX+Thu, Jun 19, 2008 - 12:00 AM
Since video card temperatures and the heat generated by next-generation cards have become an area of concern among enthusiasts and gamers, we want to take a closer look at how these cards generate heat under load.
In order to get proper temperature readings we used the Precision Overclocking Utility along with GPU-Z on the NVIDIA cards and the Catalyst Control Center along with GPU-Z on the ATI card. Both utilities showed the same temperature, so it seemed pretty valid as you can see above.
Test Results: The NVIDIA GeFOrce 9800 GTX+ has great temperatures, but remember that it is a dual slot graphics card. The Sapphire Radeon HD 4850 was a bit warm for our tastes and was found to be 85C at load.
