GeForce GT 220 GDDR3 vs GeForce GTX 560 Ti

Intro

Compare all of that to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 memory runs at a speed of 1002 MHz on this model. It features 384 SPUs as well as 64 Texture Address Units and 32 ROPs.

	Difference: 95872 (296%)

Texel Rate

The GeForce GTX 560 Ti is quite a bit (more or less 426%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 42608 (426%)

Pixel Rate

The GeForce GTX 560 Ti is quite a bit (about 426%) faster with regards to FSAA than the GeForce GT 220 GDDR3, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 21304 (426%)

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 (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 in one second. This figure is calculated by multiplying the total number of texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 memory bandwidth is, the lower the ability to get to the max fill rate.
