GeForce 9600 GSO 512MB vs Radeon HD 6750

Intro

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

GeForce 9600 GSO 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 9600 GSO 512MB will be just a bit (approximately 20%) faster with regards to anisotropic filtering than the Radeon HD 6750. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6750 is superior to the GeForce 9600 GSO 512MB, but only just. (explain)

Radeon HD 6750		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: Memory bandwidth is the max amount of information (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 card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
