GeForce 810M vs GeForce GT 210

Intro

Compare those specs to the GeForce GT 210, which makes use of a 40 nm design. nVidia has clocked the core frequency at 589 MHz. The DDR3 RAM works at a speed of 800 MHz on this particular model. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GT 210		31 Watts
	Difference: 16 Watts (107%)

Memory Bandwidth

In theory, the GeForce 810M is 13% faster than the GeForce GT 210 overall, because of its higher data rate. (explain)

GeForce 810M		14400 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 810M should be a lot (more or less 25%) faster with regards to anisotropic filtering than the GeForce GT 210. (explain)

GeForce 810M		5904 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 1192 (25%)

Pixel Rate

The GeForce 810M should be quite a bit (approximately 25%) faster with regards to AA than the GeForce GT 210, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce 810M		2952 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 596 (25%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
