GeForce GTX 260 vs Radeon HD 5830

Intro

The GeForce GTX 260 features a GPU core clock speed of 576 MHz, and the 896 MB of GDDR3 RAM is set to run at 999 MHz through a 448-bit bus. It also is comprised of 192 Stream Processors, 64 TAUs, and 28 Raster Operation Units.

Compare all of that to the Radeon HD 5830, which features a clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It is comprised of 1120(224x5) SPUs, 56 TAUs, and 16 ROPs.

The Radeon HD 5830 will be a lot (more or less 22%) faster with regards to AF than the GeForce GTX 260. (explain)

Radeon HD 5830 44800 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 7936 (22%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 260 is the winner, by a large margin. (explain)

GeForce GTX 260 16128 Mpixels/sec
Radeon HD 5830 12800 Mpixels/sec
Difference: 3328 (26%)

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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
