Compare any two graphics cards:
GeForce 840M vs GeForce GT 210
IntroThe GeForce 840M features a GPU core clock speed of 1029 MHz, and the 2048 MB of DDR3 RAM is set to run at 1000 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 ROPs.Compare 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 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 840M should in theory be much faster than the GeForce GT 210 in general. (explain)
Texel RateThe GeForce 840M should be a lot (approximately 424%) more effective at anisotropic filtering than the GeForce GT 210. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 840M is superior to the GeForce GT 210, by far. (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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
