GeForce GTX 280 vs GeForce GTX 285 1GB

Intro

The GeForce GTX 280 comes with a GPU clock speed of 602 MHz, and the 1024 MB of GDDR3 memory is set to run at 1107 MHz through a 512-bit bus. It also is made up of 240 Stream Processors, 80 TAUs, and 32 Raster Operation Units.

Compare that to the GeForce GTX 285 1GB, which comes with a GPU core clock speed of 648 MHz, and 1024 MB of GDDR3 memory running at 1242 MHz through a 512-bit bus. It also features 240 Stream Processors, 80 Texture Address Units, and 32 ROPs.

GeForce GTX 285 1GB 158976 MB/sec
GeForce GTX 280 141696 MB/sec
Difference: 17280 (12%)

Texel Rate

The GeForce GTX 285 1GB will be a bit (approximately 8%) more effective at AF than the GeForce GTX 280. (explain)

GeForce GTX 285 1GB 51840 Mtexels/sec
GeForce GTX 280 48160 Mtexels/sec
Difference: 3680 (8%)

Pixel Rate

The GeForce GTX 285 1GB should be a little bit (about 8%) better at anti-aliasing than the GeForce GTX 280, and also able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 285 1GB 20736 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 1472 (8%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
