GeForce 810M vs GeForce GT 130

Intro

Compare those specifications to the GeForce GT 130, which comes with clock speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 memory. 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

Theoretically speaking, the GeForce 810M should be 20% faster than the GeForce GT 130 overall, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GT 130 should be much (more or less 103%) faster with regards to AF than the GeForce 810M. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 130 is the winner, 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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 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 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 is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
