GeForce GTX 460 vs GeForce GTX 560

Intro

Compare all that to the GeForce GTX 560, which has GPU core 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 Stream Processors, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the GeForce GTX 560 should in theory be quite a bit superior to 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 should be a small bit (approximately 20%) faster with regards to anisotropic 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 high levels of AA 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		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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
