PCGH: exclusive benchmarks from AMDs Quad Crossfire
PCGH had the chance to do some hands-on sessions with a Quad Crossfire system in Munich with AMD. In our test system, two HD 3870 X2s worked together hand in hand.
The benchmarks were done by our graphics card editor Daniel Waadt in AMD's offices. Although we had some AMD bodyguards with us, we were totally free in deciding with benchmarks and which settings we would like to test. To measure the performance of four chips - you might remember that the HD 3870 X2 has two GPUs - we used several programs like Crysis in DX10, UT3, Call of Duty 4 and 3DMark 06.

The testbed we used was the yet to be released Phenom 9900 with 2.6 GHz, two GiByte RAM and Windows Vista x64. The average performance gain with Quad Crossfire was 38,7 percent which is quite good. In some cases, especially when the CPU didn't limit the performance like in UT3, we got an impressive gain of 119 percent. All benchmarks and pictures of the tested are to be found in our image gallery. We offer you as well some video impressions of the card.
It's safe to assume that the final Radeon driver with Quad Crossfire support is to be released soon. If so, we will update our tests on Intel systems.
