GeForce 9600 GT 512MB vs Radeon HD 6750

Intro

Compare all of that to the Radeon HD 6750, which has a core 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 features 720 SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

GeForce 9600 GT 512MB		95 Watts
	Difference: 9 Watts (10%)

Memory Bandwidth

Performance-wise, the Radeon HD 6750 should in theory be just a bit superior to the GeForce 9600 GT 512MB overall. (explain)

Radeon HD 6750		64000 MB/sec
GeForce 9600 GT 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The Radeon HD 6750 will be a lot (about 25%) better at anisotropic filtering than the GeForce 9600 GT 512MB. (explain)

Radeon HD 6750		26100 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 5300 (25%)

Pixel Rate

The Radeon HD 6750 is a little bit (approximately 12%) more effective at AA than the GeForce 9600 GT 512MB, and also capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 9600 GT 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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends 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.
