GeForce 920M vs GeForce GT 210

Intro

Compare those specifications to the GeForce GT 210, which uses a 40 nm design. nVidia has clocked the core speed at 589 MHz. The DDR3 memory runs at a frequency of 800 MHz on this model. It features 16 SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 920M should in theory be a small bit faster than the GeForce GT 210 overall. (explain)

GeForce 920M		14400 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 920M should be quite a bit (more or less 548%) faster with regards to anisotropic filtering than the GeForce GT 210. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 25816 (548%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 920M is a better choice, by a large margin. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 5276 (224%)

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 transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed in one second. This 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
