GeForce GTX 460 SE vs GeForce GTX 570

Intro

Compare that to the GeForce GTX 570, which uses a 40 nm design. nVidia has set the core speed at 732 MHz. The GDDR5 memory runs at a speed of 950 MHz on this specific model. It features 480 SPUs as well as 60 TAUs and 40 ROPs.

GeForce GTX 460 SE		108800 MB/sec
	Difference: 43200 (40%)

Texel Rate

The GeForce GTX 570 will be a lot (more or less 41%) more effective at AF than the GeForce GTX 460 SE. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 12720 (41%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 570 is the winner, by far. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 8480 (41%)

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 (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
