GeForce GT 210 vs GeForce GT 420

Intro

Compare that to the GeForce GT 420, which comes with core clock speeds of 700 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR3 RAM. It features 48 SPUs as well as 8 Texture Address Units and 4 ROPs.

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

The GeForce GT 420, in theory, should perform much faster than the GeForce GT 210 in general. (explain)

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

Texel Rate

The GeForce GT 420 should be just a bit (approximately 19%) more effective at anisotropic 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 it probably won't make a huge difference. (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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
