GeForce 810M vs GeForce GTX 580

Intro

Compare those specifications to the GeForce GTX 580, which has GPU core speed of 772 MHz, and 1536 MB of GDDR5 memory set to run at 1002 MHz through a 384-bit bus. It also is comprised of 512 Stream Processors, 64 Texture Address Units, and 48 ROPs.

GeForce 810M		14400 MB/sec
	Difference: 177984 (1236%)

Texel Rate

The GeForce GTX 580 will be much (approximately 737%) more effective at AF than the GeForce 810M. (explain)

GeForce GTX 580		49408 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 43504 (737%)

Pixel Rate

The GeForce GTX 580 is a lot (more or less 1155%) better at FSAA than the GeForce 810M, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 580		37056 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 34104 (1155%)

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 data (measured in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If 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 can be processed in one second. This is worked out by multiplying the total texture units of the card by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
