Geforce GTX 680 vs Radeon HD 5870

Intro

The Geforce GTX 680 comes with a clock frequency of 1006 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It features 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Compare that to the Radeon HD 5870, which features core clock speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 RAM. It features 1600(320x5) SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Radeon HD 5870 153600 MB/sec
Difference: 38656 (25%)

Texel Rate

The Geforce GTX 680 will be much (approximately 89%) better at anisotropic filtering than the Radeon HD 5870. (explain)

Geforce GTX 680 128768 Mtexels/sec
Radeon HD 5870 68000 Mtexels/sec
Difference: 60768 (89%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 680 is superior to the Radeon HD 5870, not by a very large margin though. (explain)

Geforce GTX 680 32192 Mpixels/sec
Radeon HD 5870 27200 Mpixels/sec
Difference: 4992 (18%)

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 MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
