GeForce 9600 GT 512MB vs Radeon HD 6750

Intro

Compare that to the Radeon HD 6750, which uses a 40 nm design. ATi has set the core speed at 725 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this specific card. 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		86 Watts
GeForce 9600 GT 512MB		95 Watts
	Difference: 9 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 should be 11% quicker than the GeForce 9600 GT 512MB in general, due to its greater data rate. (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 much (more or less 25%) better at texture 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 will be a small bit (more or less 12%) better at anti-aliasing than the GeForce 9600 GT 512MB, and also should be capable of handling higher screen resolutions without slowing down too much. (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 max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed 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. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
