Beyond Gaming - NVIDIA GeForce GTX 280 1GB GDDR3

Temperature and Power Consumption

Temperature

The GeForce GTX 280 performed much like NVIDIA claimed as we recorded a core temperature of around 72 degrees Celsius during our temperature test. This was slightly better than the GeForce 9800 GX2 and comparable to the other high-end GPUs. Note that this was conducted with the GTX 280 smart fan in automatic mode, so it wasn't noisy.

Power Consumption

With a power meter, we could measure the power draw of the entire system and the results below are what we got for the various high-end cards, on Windows Vista running 3DMark Vantage Performance preset. A 1200W Thermaltake PSU was used for this. While our test was unable to isolate the specific power draw of the GeForce GTX 280, the idle power draw of the entire system with that card was lower than all the other cards here, which showed that NVIDIA had indeed improved the dynamic power management on the GTX 280. At peak however, the GTX 280 was as power hungry as the high-end GPUs nowadays and our readings more or less correlate with what we know about this card (236W maximum TDP).
