GeForce 810M vs GeForce GTX 260 Core 216

Intro

Compare that to the GeForce GTX 260 Core 216, which features GPU clock speed of 576 MHz, and 896 MB of GDDR3 memory running at 999 MHz through a 448-bit bus. It also is comprised of 216 SPUs, 72 TAUs, and 28 ROPs.

GeForce 810M		14400 MB/sec
	Difference: 97488 (677%)

Texel Rate

The GeForce GTX 260 Core 216 should be much (approximately 602%) more effective at texture filtering than the GeForce 810M. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 35568 (602%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 260 Core 216 is the winner, by far. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 13176 (446%)

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 (measured in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number 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 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 video card can possibly write 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 core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
