GeForce 8800 GS vs Radeon HD 6750

Intro

Compare those specs to the Radeon HD 6750, which uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular card. It features 720 SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Radeon HD 6750		86 Watts
GeForce 8800 GS		105 Watts
	Difference: 19 Watts (22%)

Memory Bandwidth

The Radeon HD 6750, in theory, should be a lot faster than the GeForce 8800 GS in general. (explain)

Radeon HD 6750		64000 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The GeForce 8800 GS is just a bit (more or less 1%) more effective at AF than the Radeon HD 6750. (explain)

GeForce 8800 GS		26400 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 300 (1%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 6750 is superior to the GeForce 8800 GS, by far. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 5000 (76%)

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 largest amount of information (counted in MB per second) that can be transferred over 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 memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This figure is worked out 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 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 chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
