3DMark06 Test Results

3DMark is a computer benchmark by Futuremark (formerly named Mad Onion) to determine the DirectX 9 performance of 3D game performance with graphics cards. 3DMark06 uses advanced real-time 3D game workloads to measure PC performance using a suite of DirectX 9 3D graphics tests, CPU tests, and 3D feature tests.

3DMark06 tests include all new HDR/SM3.0 graphics tests, SM2.0 graphics tests, AI and physics driven single and multiple cores or processor CPU tests and a collection of comprehensive feature tests to reliably measure next generation gaming performance today. Some enthusiasts may note that Benchmark Reviews does not include CPU-bound tests in our benchmark battery, and that only graphic-bound tests are included.

Here at Benchmark Reviews, we believe that synthetic benchmark tools are just as valuable as video games, but only so long as you're comparing apples to apples. Since the same test is applied in the same controlled method with each test run, I believe 3DMark is a very reliable tool for comparing graphic cards against one-another.

Shader Model 2.0

Our first series of synthetic tests are performed at 1680x1050, and demands only 1.764 megapixels from the graphics card. Beginning with Shader Model 2.0 tests, Return to Proxycon and Firefly Forest are two fast-paced fast-moving scenes that put strain on the GPU's efficiency by calling for large amounts of low-demand graphics in need of high-speed output. Shader Model 2.0 tests have historically performed at slower frame rates when compared to Shader Model 3.0; at least this is the case on newer, more complex, video cards with larger overhead.



Shader Model 3.0 / HDR

The Shader Model 3.0 and HDR (High Dynamic Range) test series in 3dMark06 includes the Canyon Flight and Deep Freeze. Both of these test scenes demand intense graphical computations from the GPU, and when paired with newer (AMD Phenom or Intel Nehalem) processors can actually produce better frame rates than Shader Model 2.0 scenes with the same hardware (and overhead). At 1920x1200 the graphics card is called-on to produce 2.3 megapixels, which is enough to separate the weak from the strong.



Usually our frame rate performance test results do well enough to speak for themselves, but allow me to add a bit of commentary if you will. The GeForce 8800 GT was included to add low-end perspective, and while it's an excellent video card for low-resolution 1024x768 gaming and still fine at 1280x1024, really falls beneath the 30 FPS range at 1650x1200 and drops down into the low teens at 1920x1200. The Radeon HD 4850 is the most affordable video card to handle 3DMark06 graphics within acceptable range, with the reference GeForce GTX 260 performing a few frames better at each scene. The overclocked ASUS GeForce GTX 285 managed only 33.5 FPS at 1920x1200 resolution, which was easily outdone by Radeon counterparts. Sapphire's Toxic HD4890 scored an impressive 37.5 FPS, while the CrossFireX pair of reference 4770's pushed 38.9 FPS. The GeForce GTX 295 offered 45.3 FPS to illustrate the high-end comparison.

Take the 3DMark06 tests at face value (as you should any synthetic benchmark), because in our next section we begin real-world testing on a cadre of popular video games known for taxing the graphics processor, and the performance curve is expected change. Our first up is Call of Duty 4, so please continue on...
