GeForce GTX 460 SE vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which has a core clock speed of 810 MHz and a GDDR5 memory speed of 1001 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 560 should theoretically be just a bit faster than the GeForce GTX 460 SE in general. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GTX 460 SE		108800 MB/sec
	Difference: 19328 (18%)

Texel Rate

The GeForce GTX 560 will be quite a bit (about 45%) better at texture filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 14160 (45%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 560 is the winner, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 5120 (25%)

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 data (counted in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
