Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs GeForce GTX 850M
IntroThe GeForce GT 240 GDDR5 1GB has a GPU core speed of 550 MHz, and the 1024 MB of GDDR5 memory is set to run at 850 MHz through a 128-bit bus. It also is made up of 96 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare all of that to the GeForce GTX 850M, which comes with GPU core speed of 876 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 240 GDDR5 1GB should in theory be quite a bit better than the GeForce GTX 850M in general. (explain)
Texel RateThe GeForce GTX 850M will be quite a bit (more or less 99%) faster with regards to AF than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateThe GeForce GTX 850M will be much (about 219%) faster with regards to anti-aliasing than the GeForce GT 240 GDDR5 1GB, and also should be capable of handling higher screen 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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
