GeForce GTX 580 3GB vs Radeon HD 5570

Intro

Compare that to the Radeon HD 5570, which comes with GPU core speed of 650 MHz, and 512 MB of DDR3 memory set to run at 900 MHz through a 128-bit bus. It also features 400(80x5) Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Radeon HD 5570		13000 Mtexels/sec
	Difference: 36408 (280%)

Pixel Rate

The GeForce GTX 580 3GB is a lot (about 613%) more effective at FSAA than the Radeon HD 5570, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 580 3GB		37056 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 31856 (613%)

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 information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
