GeForce GTX 570 vs Radeon HD 5830

Intro

Compare all of that to the Radeon HD 5830, which makes use of a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this particular card. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 ROPs.

Memory Bandwidth

As far as performance goes, the GeForce GTX 570 should in theory be a little bit superior to the Radeon HD 5830 in general. (explain)

GeForce GTX 570		152000 MB/sec
Radeon HD 5830		128000 MB/sec
	Difference: 24000 (19%)

Texel Rate

The Radeon HD 5830 should be a bit (more or less 2%) faster with regards to anisotropic filtering than the GeForce GTX 570. (explain)

Radeon HD 5830		44800 Mtexels/sec
GeForce GTX 570		43920 Mtexels/sec
	Difference: 880 (2%)

Pixel Rate

The GeForce GTX 570 will be much (more or less 129%) more effective at FSAA than the Radeon HD 5830, and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 16480 (129%)

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 largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
