GeForce GT 210 vs GeForce GT 420

Intro

Compare those specs to the GeForce GT 420, which features GPU clock speed of 700 MHz, and 2048 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also is comprised of 48 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce GT 420		50 Watts
	Difference: 19 Watts (61%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 420 will be 125% faster than the GeForce GT 210 overall, due to its greater data rate. (explain)

GeForce GT 420		28800 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 16000 (125%)

Texel Rate

The GeForce GT 420 will be a little bit (about 19%) more effective at texture filtering than the GeForce GT 210. (explain)

GeForce GT 420		5600 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 888 (19%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 420 is the winner, but only just. (explain)

GeForce GT 420		2800 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 444 (19%)

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 largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount 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 number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
