GeForce 825M vs GeForce GT 210

Intro

Compare all of that to the GeForce GT 210, which comes with GPU core speed of 589 MHz, and 512 MB of DDR3 RAM running at 800 MHz through a 64-bit bus. It also features 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce 825M should perform a 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 (approximately 189%) more effective at texture filtering than the GeForce GT 210. (explain)

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

Pixel Rate

The GeForce 825M is a lot (approximately 189%) more effective at full screen anti-aliasing than the GeForce GT 210, and should be capable of handling higher screen resolutions without slowing down too much. (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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
