GeForce 8800 GTS (G92) vs Radeon HD 6750

Intro

The GeForce 8800 GTS (G92) comes with a GPU core clock speed of 650 MHz, and the 512 MB of GDDR3 memory runs at 970 MHz through a 256-bit bus. It also features 128 SPUs, 64 TAUs, and 16 ROPs.

Compare those specifications to the Radeon HD 6750, which features core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 720 SPUs along with 36 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 should be 3% quicker than the GeForce 8800 GTS (G92) in general, because of its higher data rate. (explain)

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

Texel Rate

The GeForce 8800 GTS (G92) should be quite a bit (approximately 59%) better 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

The Radeon HD 6750 is a little bit (more or less 12%) faster with regards to anti-aliasing than the GeForce 8800 GTS (G92), and will be able to handle higher screen resolutions while still performing well. (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 data (in units of MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
