GeForce 825M vs GeForce GT 210

Intro

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

In theory, the GeForce 825M is 13% faster than the GeForce GT 210 in general, due to its greater data rate. (explain)

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

Texel Rate

The GeForce 825M should be a lot (more or less 189%) more effective 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

The GeForce 825M should be quite a bit (about 189%) more effective at AA than the GeForce GT 210, and also capable of handling higher resolutions more effectively. (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 max amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its 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 the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 get to the maximum fill rate.
