GeForce 810M vs GeForce GTX 285 2GB

Intro

Compare all that to the GeForce GTX 285 2GB, which features core clock speeds of 648 MHz on the GPU, and 1242 MHz on the 2048 MB of GDDR3 memory. It features 240 SPUs as well as 80 Texture Address Units and 32 ROPs.

GeForce 810M		14400 MB/sec
	Difference: 144576 (1004%)

Texel Rate

The GeForce GTX 285 2GB is quite a bit (more or less 778%) more effective at AF than the GeForce 810M. (explain)

GeForce GTX 285 2GB		51840 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 45936 (778%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 285 2GB is the winner, by far. (explain)

GeForce GTX 285 2GB		20736 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 17784 (602%)

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 max amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the max fill rate.
