GeForce 810M vs GeForce GT 130

Intro

Compare all of that to the GeForce GT 130, which uses a 55 nm design. nVidia has clocked the core frequency at 500 MHz. The DDR2 RAM works at a speed of 250 MHz on this card. It features 48 SPUs as well as 24 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GT 130		75 Watts
	Difference: 60 Watts (400%)

Memory Bandwidth

The GeForce 810M should in theory perform a bit faster than the GeForce GT 130 overall. (explain)

GeForce 810M		14400 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 2400 (20%)

Texel Rate

The GeForce GT 130 is a lot (more or less 103%) faster with regards to texture filtering than the GeForce 810M. (explain)

GeForce GT 130		12000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 6096 (103%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 130 is the winner, by far. (explain)

GeForce GT 130		8000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 5048 (171%)

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 megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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.
