GeForce GT 220 GDDR3 vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which has core clock 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.

GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 95744 (296%)

Texel Rate

The GeForce GTX 560 will be a lot (about 354%) more effective at texture filtering than the GeForce GT 220 GDDR3. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 35360 (354%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 is superior to the GeForce GT 220 GDDR3, and very much so. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 20920 (418%)

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 MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
