Compare any two graphics cards:
GeForce GT 220 GDDR3 vs GeForce GTX 850M
IntroThe GeForce GT 220 GDDR3 has a GPU clock speed of 625 MHz, and the 512 MB of GDDR3 memory runs at 1012 MHz through a 128-bit bus. It also is comprised of 48 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the GeForce GTX 850M, which comes with GPU core speed of 876 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 220 GDDR3 is 1% faster than the GeForce GTX 850M in general, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 850M is a lot (about 250%) faster with regards to anisotropic filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateThe GeForce GTX 850M will be a lot (more or less 180%) better at full screen anti-aliasing than the GeForce GT 220 GDDR3, and also should be able to handle 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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
