GeForce 9600 GT 512MB vs Radeon HD 6750 1GB

Intro

Compare those specs to the Radeon HD 6750 1GB, which makes use of a 40 nm design. ATi has clocked the core frequency at 725 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular model. It features 720 SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750 1GB		86 Watts
GeForce 9600 GT 512MB		95 Watts
	Difference: 9 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 1GB should perform a bit faster than the GeForce 9600 GT 512MB overall. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce 9600 GT 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The Radeon HD 6750 1GB is quite a bit (approximately 25%) better at AF than the GeForce 9600 GT 512MB. (explain)

Radeon HD 6750 1GB		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 1GB is superior to the GeForce 9600 GT 512MB, but it probably won't make a huge difference. (explain)

Radeon HD 6750 1GB		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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
