GeForce 810M vs GeForce GT 220 GDDR3

Intro

Compare those specs to the GeForce GT 220 GDDR3, which comes with a clock frequency of 625 MHz and a GDDR3 memory speed of 1012 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is made up of 48 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce GT 220 GDDR3 should theoretically perform quite a bit faster than the GeForce 810M in general. (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 (approximately 69%) faster with regards to texture 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 lots of anti-aliasing is important to you, then the GeForce GT 220 GDDR3 is superior to the GeForce 810M, and very much so. (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: Bandwidth is the largest amount of information (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at 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 write to the local memory in one second - measured in millions of pixels per second. The number is worked out 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
