GeForce GTX 460 1GB vs GeForce GTX 570

Intro

Compare those specifications to the GeForce GTX 570, which makes use of a 40 nm design. nVidia has set the core frequency at 732 MHz. The GDDR5 memory is set to run at a frequency of 950 MHz on this model. It features 480 SPUs as well as 60 TAUs and 40 ROPs.

GeForce GTX 460 1GB		160 Watts
GeForce GTX 570		219 Watts
	Difference: 59 Watts (37%)

Memory Bandwidth

The GeForce GTX 570, in theory, should perform a lot faster than the GeForce GTX 460 1GB overall. (explain)

GeForce GTX 570		152000 MB/sec
GeForce GTX 460 1GB		115200 MB/sec
	Difference: 36800 (32%)

Texel Rate

The GeForce GTX 570 should be a little bit (more or less 16%) better at texture filtering than the GeForce GTX 460 1GB. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 6120 (16%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 570 is the winner, by far. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GTX 460 1GB		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: Memory bandwidth is the largest amount of data (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 type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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