GeForce GTX 460 SE vs GeForce GTX 560

Intro

Compare those specs to the GeForce GTX 560, which has a core clock speed of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 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 will be 18% quicker than the GeForce GTX 460 SE overall, because of its higher bandwidth. (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 (approximately 45%) better 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

The GeForce GTX 560 should be quite a bit (approximately 25%) faster with regards to FSAA than the GeForce GTX 460 SE, and should be capable of handling higher screen resolutions without losing too much performance. (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 largest amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
