GeForce 8800 GTS (G92) vs Radeon HD 6750

Intro

Compare all of that to the Radeon HD 6750, which has a GPU core clock speed of 725 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is comprised of 720 Stream Processors, 36 TAUs, and 16 Raster Operation Units.

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

The Radeon HD 6750, in theory, should perform a little bit faster than the GeForce 8800 GTS (G92) overall. (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 a lot (more or less 59%) faster with regards to texture 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 using high levels of AA is important to you, then the Radeon HD 6750 is the winner, but 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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
