GeForce GTX 280 vs Radeon HD 7870

Intro

The GeForce GTX 280 has a GPU core clock speed of 602 MHz, and the 1024 MB of GDDR3 memory runs at 1107 MHz through a 512-bit bus. It also is comprised of 240 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Compare all of that to the Radeon HD 7870, which has clock speeds of 1000 MHz on the GPU, and 1200 MHz on the 2048 MB of GDDR5 memory. It features 1280 SPUs along with 80 TAUs and 32 ROPs.

Texel Rate

The Radeon HD 7870 will be much (more or less 66%) better at texture filtering than the GeForce GTX 280. (explain)

Radeon HD 7870 80000 Mtexels/sec
GeForce GTX 280 48160 Mtexels/sec
Difference: 31840 (66%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 7870 is superior to the GeForce GTX 280, by a large margin. (explain)

Radeon HD 7870 32000 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 12736 (66%)

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 max amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
