GeForce GTX 460 SE vs GeForce GTX 560

Intro

Compare all that to the GeForce GTX 560, which has a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 RAM running at 1001 MHz through a 256-bit bus. It also features 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 560 should perform a small 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 should be quite a bit (about 45%) more effective at anisotropic 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 560 is the winner, and very much so. (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 information (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
