GeForce 810M vs GeForce GT 220 GDDR3

Intro

Compare that to the GeForce GT 220 GDDR3, which features GPU clock speed of 625 MHz, and 512 MB of GDDR3 memory running at 1012 MHz through a 128-bit bus. It also features 48 SPUs, 16 TAUs, and 8 ROPs.

GeForce 810M		15 Watts
GeForce GT 220 GDDR3		58 Watts
	Difference: 43 Watts (287%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 220 GDDR3 will be 125% quicker than the GeForce 810M in general, due to its greater bandwidth. (explain)

GeForce GT 220 GDDR3		32384 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 17984 (125%)

Texel Rate

The GeForce GT 220 GDDR3 should be much (about 69%) better at anisotropic filtering than the GeForce 810M. (explain)

GeForce GT 220 GDDR3		10000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 4096 (69%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 220 GDDR3 is superior to the GeForce 810M, by a large margin. (explain)

GeForce GT 220 GDDR3		5000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 2048 (69%)

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 (in units of megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
