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.



Looking over the results between 1680x1050 and 1920x1280 resolution, it appears the that Radeon HD 4770 matches performance with the GeForce 8800 GT and HD4850 in all SM 2.0 tests. Moving to the SM3/HDR tests, the HD4770 easily out-performs the GeForce 8800 GT, and trails slightly behind the HD4850 and GTX 260. The Radeon HD 4870 trails right behind the HD4890, and the GeForce GTX 285 comes in both above and below the Radeon HD 4890, depending on the test.

The verdict for 3dMark06: HD4770 matches a GeForce 8800 GT and Radeon HD 4850 in shader model 2.0 tests, which appear to favor NVIDIA GeForce products over ATI Radeon GPU's. Shader Model 3.0 / High Dynamic Range tests are more unbiased, and have the HD4770 well-ahead of the 8800 GT, and slightly behind a Radeon HD 4850.

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...



# Video card in minicomputerJaap J. van Veen 2011-08-31 01:49
I own a Shuttle XPC from 2004. It has an FN41 motherboard with an Vidia GeForce MX Integrated GPU (32MB). I had to buy a new screen which has 1920x1080 pixels. Now my internal graphics card is running short of capacity (flickering). I bought an AGP8x Videocard but the size of the computer does not allow to install the card (cooling ribs too high, MSI NX6200AX-TD512H). I have also a half PCE slot empty. The computerpower is 250Watt. Please advise for which Videocard I have to look for.
