GeForce GT 210 vs GeForce GTX 660

Intro

Compare all of that to the GeForce GTX 660, which has GPU clock speed of 980 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 192-bit bus. It also is comprised of 960 Stream Processors, 80 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce GTX 660		140 Watts
	Difference: 109 Watts (352%)

Memory Bandwidth

In theory, the GeForce GTX 660 should be a lot faster than the GeForce GT 210 in general. (explain)

GeForce GTX 660		144192 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 131392 (1027%)

Texel Rate

The GeForce GTX 660 will be quite a bit (about 1564%) faster with regards to 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 is quite a bit (more or less 898%) faster with regards to anti-aliasing than the GeForce GT 210, and should be capable of handling higher resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 can be applied in one second. This figure 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 handling 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 graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
