GeForce 9600 GSO 768MB vs Radeon HD 6750

Intro

Compare that to the Radeon HD 6750, which has core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.

The GeForce 9600 GSO 768MB will be a little bit (approximately 1%) better at AF than the Radeon HD 6750. (explain)

GeForce 9600 GSO 768MB		26400 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 300 (1%)

Pixel Rate

The Radeon HD 6750 should be quite a bit (more or less 76%) better at FSAA than the GeForce 9600 GSO 768MB, and will be able to handle higher screen resolutions more effectively. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 9600 GSO 768MB		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 data (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units 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 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 ability to get to the max fill rate.
