GeForce GTX 460 SE 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 RAM. 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

Performance-wise, the GeForce GTX 560 should in theory be a little bit better than the GeForce GTX 460 SE overall. (explain)

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

Texel Rate

The GeForce GTX 560 will be quite a bit (about 45%) better at AF 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 will be quite a bit (more or less 25%) more effective at full screen anti-aliasing than the GeForce GTX 460 SE, and also able to handle higher screen resolutions better. (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: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
