GeForce 8800 GTX vs Radeon HD 6950

Intro

The GeForce 8800 GTX makes use of a 90 nm design. nVidia has set the core frequency at 575 MHz. The GDDR3 memory works at a frequency of 900 MHz on this specific card. It features 128 SPUs as well as 64 TAUs and 24 ROPs.

Compare those specs to the Radeon HD 6950, which features core speeds of 800 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

GeForce 8800 GTX 86400 MB/sec
Difference: 73600 (85%)

Texel Rate

The Radeon HD 6950 should be a lot (more or less 91%) better at anisotropic filtering than the GeForce 8800 GTX. (explain)

Radeon HD 6950 70400 Mtexels/sec
GeForce 8800 GTX 36800 Mtexels/sec
Difference: 33600 (91%)

Pixel Rate

The Radeon HD 6950 is quite a bit (about 86%) better at AA than the GeForce 8800 GTX, and capable of handling higher resolutions while still performing well. (explain)

Radeon HD 6950 25600 Mpixels/sec
GeForce 8800 GTX 13800 Mpixels/sec
Difference: 11800 (86%)

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 max amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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