GeForce 810M vs GeForce GT 220 GDDR3

Intro

Compare those specs 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 is comprised of 48 Stream Processors, 16 Texture Address Units, and 8 ROPs.

GeForce 810M		14400 MB/sec
	Difference: 17984 (125%)

Texel Rate

The GeForce GT 220 GDDR3 should be a lot (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

The GeForce GT 220 GDDR3 will be quite a bit (more or less 69%) more effective at AA than the GeForce 810M, and also should be able to handle higher resolutions better. (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 information (counted in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
