GeForce 8600 GT 512MB DDR2 vs Radeon HD 5750 1GB

Intro

Compare all that to the Radeon HD 5750 1GB, which has a clock frequency of 700 MHz and a GDDR5 memory speed of 1150 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 720(144x5) SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Radeon HD 5750 1GB		73600 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 60800 (475%)

Texel Rate

The Radeon HD 5750 1GB should be a lot (more or less 192%) faster with regards to texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon HD 5750 1GB		25200 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 16560 (192%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5750 1GB is superior to the GeForce 8600 GT 512MB DDR2, by far. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 6880 (159%)

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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
