GeForce 8800 GTS (G92) vs Radeon HD 6750

Intro

The GeForce 8800 GTS (G92) comes with core speeds of 650 MHz on the GPU, and 970 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare all of that to the Radeon HD 6750, which makes use of a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific model. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Radeon HD 6750 86 Watts
GeForce 8800 GTS (G92) 135 Watts
Difference: 49 Watts (57%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 is 3% quicker than the GeForce 8800 GTS (G92) overall, due to its greater bandwidth. (explain)

Radeon HD 6750 64000 MB/sec
GeForce 8800 GTS (G92) 62080 MB/sec
Difference: 1920 (3%)

Texel Rate

The GeForce 8800 GTS (G92) is much (about 59%) more effective at anisotropic filtering than the Radeon HD 6750. (explain)

GeForce 8800 GTS (G92) 41600 Mtexels/sec
Radeon HD 6750 26100 Mtexels/sec
Difference: 15500 (59%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 6750 is a better choice, though not by far. (explain)

Radeon HD 6750 11600 Mpixels/sec
GeForce 8800 GTS (G92) 10400 Mpixels/sec
Difference: 1200 (12%)

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 maximum amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
