GeForce 825M vs GeForce GT 210

Intro

Compare those specifications to the GeForce GT 210, which features a core clock frequency of 589 MHz and a DDR3 memory speed of 800 MHz. It also uses a 64-bit bus, and makes use of a 40 nm design. It features 16 SPUs, 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

In theory, the GeForce 825M is 13% faster than the GeForce GT 210 overall, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce 825M is a lot (more or less 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

If using a high resolution is important to you, then the GeForce 825M is superior to the GeForce GT 210, by a large margin. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 are applied in one second. This figure is calculated by multiplying the total 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 most pixels the video card can possibly write to the local memory in a 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
