GeForce GTX 285 2GB vs Radeon HD 6970

Intro

The GeForce GTX 285 2GB comes with a GPU clock speed of 648 MHz, and the 2048 MB of GDDR3 memory is set to run at 1242 MHz through a 512-bit bus. It also is comprised of 240 Stream Processors, 80 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon HD 6970, which features a clock speed of 880 MHz and a GDDR5 memory speed of 1375 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is comprised of 1536 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.

Radeon HD 6970 176000 MB/sec
GeForce GTX 285 2GB 158976 MB/sec
Difference: 17024 (11%)

Texel Rate

The Radeon HD 6970 should be quite a bit (more or less 63%) faster with regards to AF than the GeForce GTX 285 2GB. (explain)

Radeon HD 6970 84480 Mtexels/sec
GeForce GTX 285 2GB 51840 Mtexels/sec
Difference: 32640 (63%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6970 is superior to the GeForce GTX 285 2GB, by far. (explain)

Radeon HD 6970 28160 Mpixels/sec
GeForce GTX 285 2GB 20736 Mpixels/sec
Difference: 7424 (36%)

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 maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must 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 anti-aliasing, 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 number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant 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.
