GeForce 9600 GT 512MB vs Radeon HD 6750

Intro

Compare all that to the Radeon HD 6750, which uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific card. It features 720 SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.

Radeon HD 6750		86 Watts
GeForce 9600 GT 512MB		95 Watts
	Difference: 9 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 should perform a bit faster than the GeForce 9600 GT 512MB in general. (explain)

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

Texel Rate

The Radeon HD 6750 should be a lot (more or less 25%) better at AF 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

If using a high screen resolution is important to you, then the Radeon HD 6750 is superior to the GeForce 9600 GT 512MB, though only just barely. (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 (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must 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 texture map elements (texels) that are applied in one 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
