GeForce 8800 GS vs Radeon HD 6750

Intro

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

GeForce 8800 GS		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The GeForce 8800 GS should be a little bit (about 1%) better 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 running with high levels of AA is important to you, then the Radeon HD 6750 is superior to the GeForce 8800 GS, by a large margin. (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 maximum amount of information (measured in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
