GeForce GT 310 vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which features a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 RAM running at 1001 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
GeForce GTX 560		150 Watts
	Difference: 119 Watts (384%)

Memory Bandwidth

In theory, the GeForce GTX 560 should be 701% quicker than the GeForce GT 310 in general, because of its higher data rate. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 112128 (701%)

Texel Rate

The GeForce GTX 560 should be quite a bit (about 863%) faster with regards to AF than the GeForce GT 310. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 40648 (863%)

Pixel Rate

The GeForce GTX 560 is a lot (more or less 1000%) faster with regards to anti-aliasing than the GeForce GT 310, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 23564 (1000%)

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 max amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
