GeForce 9600 GT 1GB vs Radeon HD 6750

Intro

Compare all of that to the Radeon HD 6750, which has a GPU core clock speed of 725 MHz, and 512 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 720 SPUs, 36 Texture Address Units, and 16 ROPs.

The Radeon HD 6750 is a lot (approximately 25%) better at AF than the GeForce 9600 GT 1GB. (explain)

Radeon HD 6750		26100 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 5300 (25%)

Pixel Rate

The Radeon HD 6750 will be a bit (approximately 12%) faster with regards to anti-aliasing than the GeForce 9600 GT 1GB, and will be capable of handling higher screen resolutions better. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 9600 GT 1GB		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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, 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 card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
