GeForce 810M vs GeForce 830M

Intro

Compare those specifications to the GeForce 830M, which features clock speeds of 1029 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 256 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce 830M		25 Watts
	Difference: 10 Watts (67%)

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce 830M is quite a bit (more or less 179%) better at AF than the GeForce 810M. (explain)

GeForce 830M		16464 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 10560 (179%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 830M is the winner, by far. (explain)

GeForce 830M		8232 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 5280 (179%)

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 megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
