GeForce 920M vs GeForce GT 210

Intro

Compare all that to the GeForce GT 210, which uses a 40 nm design. nVidia has clocked the core frequency at 589 MHz. The DDR3 memory works at a speed of 800 MHz on this specific card. It features 16 SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 920M should be a bit faster than the GeForce GT 210 in general. (explain)

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

Texel Rate

The GeForce 920M will be a lot (about 548%) faster with regards to AF than the GeForce GT 210. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 920M is a better choice, and very much so. (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 max amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
