3DMark is a popular synthetic gaming benchmark used by many gamers and overclockers to gauge the performance of their PC's. All 3DMark runs were performed a total of 5 times with the highest and lowest results being removed and an average calculated from the remaining 3 results.
Quake 4 is a game built on the Doom 3 engine. Benchmarking was performed using Quake4Bench and a custom timedemo recording along with 4xAA, 4xAF settings at a resolution of 1600x1200 for maximum stress on the GPU. The benchmark was set to run a total of 5 times, with Quake4Bench automatically calculating an average result at the end of the run.
F.E.A.R. is a game based on the Lithtech Jupiter EX engine. It has volumetric lighting, soft shadows, parallax mapping and particle effects. Included in the game is a benchmark facility that taxes the entire PC system. This benchmark was run a total of 5 times, with the highest and lowest results being excluded and an average being calculated on the remaining 3 results.
Bioshock is a recent FPS shooter by 2K games. Based on the UT3 engine it has a large amount of advanced DirectX techniques including excellent water rendering and superb lighting and smoke techniques. All results were recorded using F.R.A.P.S with a total of 5 identical runs through the same area of the game. The highest and lowest results were then removed, with an average being calculated from the remaining 3 results.
Result Observations
While we would have ideally liked the place the Trinity against several other cards, performing a head-to-head comparison with the Asus 3850X2 gives us a clear indication of just how much use games are able to make out of that third GPU. As we can see from the graphs above, the Trinity pretty much slaughters the 3850X2, taking a 27% lead in BIOSHOCK and an almost unbelievable (but thoroughly re-producible) 34% increase in F.E.A.R. Quake 4 on the other hand, didn't seem to take much advantage of the extra GPU/memory and only showed a 4FPS increase.
