GeForce GTX 570 vs Radeon HD 5570

Intro

Compare that to the Radeon HD 5570, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this model. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Radeon HD 5570		13000 Mtexels/sec
	Difference: 30920 (238%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 570 is the winner, and very much so. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 24080 (463%)

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 largest amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs 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 of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
