GeForce GTX 570 vs Radeon HD 6950 2GB

Intro

The GeForce GTX 570 uses a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 memory is set to run at a speed of 950 MHz on this specific model. It features 480 SPUs as well as 60 Texture Address Units and 40 ROPs.

Compare that to the Radeon HD 6950 2GB, which has core speeds of 800 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 RAM. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.

Radeon HD 6950 2GB 200 Watts
GeForce GTX 570 219 Watts
Difference: 19 Watts (10%)

Memory Bandwidth

The Radeon HD 6950 2GB should in theory be just a bit faster than the GeForce GTX 570 overall. (explain)

Radeon HD 6950 2GB 160000 MB/sec
GeForce GTX 570 152000 MB/sec
Difference: 8000 (5%)

Texel Rate

The Radeon HD 6950 2GB is a lot (more or less 60%) more effective at anisotropic filtering than the GeForce GTX 570. (explain)

Radeon HD 6950 2GB 70400 Mtexels/sec
GeForce GTX 570 43920 Mtexels/sec
Difference: 26480 (60%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 570 is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 570 29280 Mpixels/sec
Radeon HD 6950 2GB 25600 Mpixels/sec
Difference: 3680 (14%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.

These benchmarks are poor. I get better average frames with my 6950 in these games (roughly 10 more in each)

In 3dsmax viewport rendering. GTX570 is poor performance. HD6950 is very smooth performance !
