Compare any two graphics cards:
GeForce GT 230 vs GeForce GTX 850M
IntroThe GeForce GT 230 comes with a GPU core clock speed of 550 MHz, and the 1536 MB of DDR3 RAM runs at 800 MHz through a 192-bit bus. It also is comprised of 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the GeForce GTX 850M, which features a core clock frequency of 876 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 230, in theory, should be just a bit faster than the GeForce GTX 850M in general. (explain)
Texel RateThe GeForce GTX 850M is quite a bit (more or less 298%) better at AF than the GeForce GT 230. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 850M is superior to the GeForce GT 230, 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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 are processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
