AMD's ATI Radeon HD 5870 vs. HD 4890 GPU Comparison - Temperature and Sound Tests

Temperature Tests



With the TES 1326 Infrared Thermometer literally in hand we found ourselves getting real-world temperatures from the products we test at load (3D clock speeds).


There are two places we pull temperature from - the back of the card directly behind the core and if the card is dual slot and has an exhaust point we also pull a temperate from there, as seen in the picture.




The better temperature seems to be a combination of better cooling, 40nm technology and an overall better design on the said cooler.


Sound Tests



Pulling out the TES 1350A Sound Level Meter we find ourselves quickly yelling into the top of it to see how loud we can be.


After five minutes of that we get a bit more serious and place the device two CM away from the fan on the card to find the maximum noise level of the card when idle (2D mode) and in load (3D mode).




The drop in temperature has fortunately been able to be done with no increase in noise, which is always pleasant.
