GeForce 9600 GSO 512MB vs Radeon HD 6750 1GB

Intro

Compare all that to the Radeon HD 6750 1GB, which has a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 720 SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

	Difference: 6400 (11%)

Texel Rate

The GeForce 9600 GSO 512MB will be a bit (about 20%) better at AF than the Radeon HD 6750 1GB. (explain)

GeForce 9600 GSO 512MB		31200 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 5100 (20%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6750 1GB is a better choice, though only just barely. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce 9600 GSO 512MB		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 max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
