GeForce GTX 580 vs Radeon HD 5830

Intro

Compare all of that to the Radeon HD 5830, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular card. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Radeon HD 5830		175 Watts
GeForce GTX 580		244 Watts
	Difference: 69 Watts (39%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 580 should theoretically be much superior to the Radeon HD 5830 in general. (explain)

GeForce GTX 580		192384 MB/sec
Radeon HD 5830		128000 MB/sec
	Difference: 64384 (50%)

Texel Rate

The GeForce GTX 580 will be a small bit (more or less 10%) faster with regards to texture filtering than the Radeon HD 5830. (explain)

GeForce GTX 580		49408 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 4608 (10%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 580 is a better choice, and very much so. (explain)

GeForce GTX 580		37056 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 24256 (190%)

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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
