GeForce GT 210 vs GeForce GTX 850M

Intro

Compare that to the GeForce GTX 850M, which comes with GPU core speed of 876 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce GTX 850M		40 Watts
	Difference: 9 Watts (29%)

Memory Bandwidth

In theory, the GeForce GTX 850M should perform much faster than the GeForce GT 210 overall. (explain)

GeForce GTX 850M		32000 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 19200 (150%)

Texel Rate

The GeForce GTX 850M will be quite a bit (about 644%) faster with regards to texture filtering than the GeForce GT 210. (explain)

GeForce GTX 850M		35040 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 30328 (644%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 850M is a better choice, and very much so. (explain)

GeForce GTX 850M		14016 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 11660 (495%)

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 max amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
