Compare any two graphics cards:
GeForce 920M vs GeForce GT 210
IntroThe GeForce 920M uses a 28 nm design. nVidia has set the core speed at 954 MHz. The DDR3 RAM runs at a frequency of 900 MHz on this particular model. It features 384 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.Compare those specs to the GeForce GT 210, which comes with a core clock frequency of 589 MHz and a DDR3 memory frequency of 800 MHz. It also features 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 BenchmarksMemory BandwidthThe GeForce 920M should theoretically be just a bit faster than the GeForce GT 210 overall. (explain)
Texel RateThe GeForce 920M should be a lot (more or less 548%) faster with regards to AF than the GeForce GT 210. (explain)
Pixel RateThe GeForce 920M is much (more or less 224%) faster with regards to AA than the GeForce GT 210, and also should be capable of handling higher resolutions more effectively. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock 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 per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock 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 fill rate is also dependant 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.
