HD 3850 Crossfire vs. 8800GTS 512MB G92

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.



As you would expect, the second card (furthest from the CPU) manages to heat up a bit more than the first, but really it's not by a huge amount and certainly nothing we would really worry about.


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).



Noise levels are only slightly up for the dual card setup, and still better than the smaller 8800GT which pumps out 70+dB when under load.
