GeForce GTX 570 vs Radeon HD 5750 1GB

Intro

Compare that to the Radeon HD 5750 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 700 MHz. The GDDR5 memory works at a frequency of 1150 MHz on this specific model. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 18720 (74%)

Pixel Rate

The GeForce GTX 570 is quite a bit (approximately 161%) faster with regards to AA than the Radeon HD 5750 1GB, and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 18080 (161%)

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 maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
