GeForce 9600 GSO 768MB vs Radeon HD 7950

Intro

Compare all of that to the Radeon HD 7950, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this specific card. It features 1792 SPUs as well as 112 TAUs and 32 ROPs.

GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 201600 (525%)

Texel Rate

The Radeon HD 7950 will be a lot (about 239%) faster with regards to AF than the GeForce 9600 GSO 768MB. (explain)

Radeon HD 7950		89600 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 63200 (239%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 7950 is the winner, by far. (explain)

Radeon HD 7950		25600 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 19000 (288%)

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 data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a 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 - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
