GeForce GTX 460 vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which comes with GPU core speed of 810 MHz, and 1024 MB of GDDR5 RAM set to run at 1001 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 560 should be 48% quicker than the GeForce GTX 460 in general, because of its greater data rate. (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 (more or less 20%) better at 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

The GeForce GTX 560 should be much (more or less 60%) faster with regards to AA than the GeForce GTX 460, and also will be capable of handling higher screen resolutions better. (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 largest amount of information (in units of MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
