GeForce 9600 GT 1GB vs Radeon HD 5670

Intro

Compare those specifications to the Radeon HD 5670, which has clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Texel Rate

The GeForce 9600 GT 1GB should be much (more or less 34%) better at AF than the Radeon HD 5670. (explain)

GeForce 9600 GT 1GB		20800 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 5300 (34%)

Pixel Rate

The GeForce 9600 GT 1GB will be much (about 68%) more effective at full screen anti-aliasing than the Radeon HD 5670, and should be able to handle higher screen resolutions better. (explain)

GeForce 9600 GT 1GB		10400 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 4200 (68%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
