GeForce GTX 460 2GB vs GeForce GTX 560

Intro

Compare those specs to the GeForce GTX 560, which has core speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560		150 Watts
GeForce GTX 460 2GB		160 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 560 should in theory be just a bit superior to the GeForce GTX 460 2GB overall. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GTX 460 2GB		115200 MB/sec
	Difference: 12928 (11%)

Texel Rate

The GeForce GTX 560 should be a bit (approximately 20%) more effective at AF than the GeForce GTX 460 2GB. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 7560 (20%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 560 is a better choice, though not by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 4320 (20%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
