GeForce 9600 GSO 512MB vs Radeon HD 6770

Intro

Compare all that to the Radeon HD 6770, which has GPU clock speed of 900 MHz, and 512 MB of GDDR5 RAM set to run at 1050 MHz through a 128-bit bus. It also features 800 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce 9600 GSO 512MB		57600 MB/sec
	Difference: 9600 (17%)

Texel Rate

The Radeon HD 6770 should be just a bit (more or less 15%) better at AF than the GeForce 9600 GSO 512MB. (explain)

Radeon HD 6770		36000 Mtexels/sec
GeForce 9600 GSO 512MB		31200 Mtexels/sec
	Difference: 4800 (15%)

Pixel Rate

The Radeon HD 6770 is a lot (approximately 38%) faster with regards to AA than the GeForce 9600 GSO 512MB, and capable of handling higher resolutions without losing too much performance. (explain)

Radeon HD 6770		14400 Mpixels/sec
GeForce 9600 GSO 512MB		10400 Mpixels/sec
	Difference: 4000 (38%)

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 (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
