Compare any two graphics cards:
GeForce 840M vs GeForce GT 210
IntroThe GeForce 840M comes with a GPU core clock speed of 1029 MHz, and the 2048 MB of DDR3 memory runs at 1000 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.Compare that to the GeForce GT 210, which features core speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 16 SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 840M should in theory perform quite a bit faster than the GeForce GT 210 overall. (explain)
Texel RateThe GeForce 840M should be quite a bit (approximately 424%) better at anisotropic filtering than the GeForce GT 210. (explain)
Pixel RateThe GeForce 840M is quite a bit (approximately 249%) better at anti-aliasing than the GeForce GT 210, and also will be capable of handling higher resolutions better. (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 largest amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated 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 applied in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
