GeForce 810M vs GeForce GT 130

Intro

Compare all that to the GeForce GT 130, which has a clock frequency of 500 MHz and a DDR2 memory speed of 250 MHz. It also uses a 192-bit memory bus, and uses a 55 nm design. It features 48 SPUs, 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 20% faster than the GeForce GT 130 in general, 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 will 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

The GeForce GT 130 is much (more or less 171%) more effective at anti-aliasing than the GeForce 810M, and will be able to handle higher screen resolutions more effectively. (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 largest amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to reach the maximum fill rate.
