GeForce GTX 460 (OEM) vs GeForce GTX 560

Intro

Compare that to the GeForce GTX 560, which features core clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 should be a little bit faster than the GeForce GTX 460 (OEM) in general. (explain)

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

Texel Rate

The GeForce GTX 560 should be a lot (about 25%) more effective at anisotropic filtering than the GeForce GTX 460 (OEM). (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 8960 (25%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 560 is superior to the GeForce GTX 460 (OEM), by a large margin. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 460 (OEM)		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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
