GeForce GTX 460 1GB vs GeForce GTX 570

Intro

Compare those specifications to the GeForce GTX 570, which comes with clock speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 RAM. It features 480 SPUs as well as 60 Texture Address Units and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX 570 should be 32% faster than the GeForce GTX 460 1GB in general, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GTX 570 is just a bit (about 16%) more effective 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 high levels of AA is important to you, then the GeForce GTX 570 is superior to the GeForce GTX 460 1GB, and very much so. (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: Bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
