GeForce GT 210 vs GeForce GTX 660

Intro

Compare all of that to the GeForce GTX 660, which has GPU core speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 192-bit bus. It also features 960 SPUs, 80 TAUs, and 24 Raster Operation Units.

GeForce GT 210		12800 MB/sec
	Difference: 131392 (1027%)

Texel Rate

The GeForce GTX 660 is much (approximately 1564%) better at texture filtering than the GeForce GT 210. (explain)

GeForce GTX 660		78400 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 73688 (1564%)

Pixel Rate

The GeForce GTX 660 will be quite a bit (approximately 898%) better at full screen anti-aliasing than the GeForce GT 210, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 660		23520 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 21164 (898%)

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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
