GeForce 825M vs GeForce GT 210

Intro

Compare all that to the GeForce GT 210, which comes with core clock speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 16 SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce 825M		33 Watts
	Difference: 2 Watts (6%)

Memory Bandwidth

The GeForce 825M, in theory, should perform a small bit faster than the GeForce GT 210 in general. (explain)

GeForce 825M		14400 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 825M should be much (about 189%) better at anisotropic filtering than the GeForce GT 210. (explain)

GeForce 825M		13600 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 8888 (189%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 825M is a better choice, by far. (explain)

GeForce 825M		6800 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 4444 (189%)

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 maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out 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 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 most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
