GeForce 9600 GT 512MB vs Radeon HD 6770

Intro

The GeForce 9600 GT 512MB has a GPU core speed of 650 MHz, and the 512 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also is made up of 64 Stream Processors, 32 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon HD 6770, which comes with GPU core speed of 900 MHz, and 512 MB of GDDR5 RAM running at 1050 MHz through a 128-bit bus. It also is made up of 800 SPUs, 40 TAUs, and 16 Raster Operation Units.

Radeon HD 6770 67200 MB/sec
GeForce 9600 GT 512MB 57600 MB/sec
Difference: 9600 (17%)

Texel Rate

The Radeon HD 6770 is much (approximately 73%) more effective at anisotropic filtering than the GeForce 9600 GT 512MB. (explain)

Radeon HD 6770 36000 Mtexels/sec
GeForce 9600 GT 512MB 20800 Mtexels/sec
Difference: 15200 (73%)

Pixel Rate

The Radeon HD 6770 is quite a bit (more or less 38%) better at anti-aliasing than the GeForce 9600 GT 512MB, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 6770 14400 Mpixels/sec
GeForce 9600 GT 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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This 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 video 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 most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
