GeForce GTX 460 2GB vs GeForce GTX 570

Intro

Compare all of that to the GeForce GTX 570, which makes use of a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 RAM runs at a speed of 950 MHz on this particular model. It features 480 SPUs as well as 60 Texture Address Units and 40 Rasterization Operator Units.

GeForce GTX 570		43920 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 6120 (16%)

Pixel Rate

The GeForce GTX 570 will be quite a bit (about 36%) better at anti-aliasing than the GeForce GTX 460 2GB, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 7680 (36%)

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 max amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of 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 worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
