GeForce 920M vs GeForce GT 210

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 920M should perform just a 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 will be a lot (approximately 548%) faster with regards to texture filtering than the GeForce GT 210. (explain)

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

Pixel Rate

The GeForce 920M is a lot (about 224%) faster with regards to full screen anti-aliasing than the GeForce GT 210, and should be able to handle higher screen resolutions more effectively. (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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at 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 that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
