DOOM 3 is a game that needs no introduction, and continues in a long line of id Software Quake and DOOM first-person shooters. This latest installment is one serious 3D game test, including some of the highest-end graphics yet seen on the PC. It is also a different type of game benchmark, especially compared to Quake 3, and it has an almost total reliance on the 3D video card for high-end framerate results. This limits its use in certain system or CPU testing, but makes DOOM 3 a killer 3D video card benchmark.
DOOM 3 represents our newer crop of gaming benchmarks, and this is really the first big test to see how the Biostar GeForce 7900 GT 256MB stacks up. As expected, it placed just ahead of the GeForce 7800 GTX, and sits right at the top of our chart. This is using standard detail settings, which allows some of the mainstream cards - like the GeForce 7600 GT 256MB - to stay relatively close to the GeForce 7900 GT. These are still excellent DOOM 3 results for the Biostar GeForce 7900 GT, and once again prove that it is a smaller, cooler-running and slightly-faster revision of the GeForce 7800 GTX.
The DOOM 3 benchmark results with 4X AA and 8X AF settings activated show much the same trends, and the Biostar GeForce 7900 GT remains the top performer, just ahead of the GeForce 7800 GTX. But unlike some other game tests, DOOM 3 does not give the Biostar GeForce 7900 GT an inherent advantage at the higher detail settings, and the relative chart position stays very consistent.
Half-Life 2 is another in a long line of serious first-person shooters from Valve, and the game has really taken FPS graphics to the next level. This is a great opportunity to really push our graphics cards to the limit, as well as proving a point-counterpoint to DOOM 3. As with DOOM 3, there is also some CPU-reliance present in the scores, but in terms of relative performance, we still find the top-performing cards breaking away from the pack.
While DOOM 3 offers an inherent advantage for NVIDIA cards, so too does Half-Life 2 offer the same kind of performance increase for the ATI side. The Radeon X1800 XL shows this off quite clearly, and posts framerates that are equal to, or even faster than, the Biostar GeForce 7900 GT.. The overall Half-Life 2 scores are still very bunched up at the default details, and it usually takes anti-aliasing and anisotropic filtering to get some separation between the comparison video cards.
The Biostar GeForce 7900 GT manages to maintain the majority of its original performance when the higher-end 4X anti-aliasing and 8X anisotropic filtering setting are enabled, while the other cards fall back by varying degrees. It is certainly easier to tell the mainstream cards from the higher-end models in this chart, than in the preceding one.
