GeForce GTX 460 vs GeForce GTX 560

Intro

Compare those specs to the GeForce GTX 560, which features GPU clock speed of 810 MHz, and 1024 MB of GDDR5 memory set to run at 1001 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the GeForce GTX 560 should perform much faster than the GeForce GTX 460 overall. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 41728 (48%)

Texel Rate

The GeForce GTX 560 is just a bit (about 20%) faster with regards to texture filtering than the GeForce GTX 460. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 7560 (20%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 is superior to the GeForce GTX 460, and very much so. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 9720 (60%)

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 largest amount of information (in units of MB 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 its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
