GeForce 810M vs GeForce GT 130

Intro

Compare that to the GeForce GT 130, which makes use of a 55 nm design. nVidia has clocked the core frequency at 500 MHz. The DDR2 memory is set to run at a frequency of 250 MHz on this specific card. It features 48 SPUs along with 24 Texture Address Units 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

Theoretically speaking, the GeForce 810M should be a small 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 quite a bit (approximately 103%) better at AF than the GeForce 810M. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 130 is superior to the GeForce 810M, by a large margin. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
