GeForce GTX 560 vs Radeon HD 5830

Intro

Compare all of that to the Radeon HD 5830, which comes with GPU clock speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also features 1120(224x5) SPUs, 56 TAUs, and 16 Raster Operation Units.

The GeForce GTX 560 should be a small bit (more or less 1%) better at texture filtering than the Radeon HD 5830. (explain)

GeForce GTX 560		45360 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 560 (1%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 is the winner, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 13120 (103%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
