Compare any two graphics cards:
GeForce GT 440 1.5GB vs GeForce GTX 870M
IntroThe GeForce GT 440 1.5GB comes with a clock frequency of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It is comprised of 144 SPUs, 24 TAUs, and 24 ROPs.Compare all that to the GeForce GTX 870M, which makes use of a 28 nm design. nVidia has set the core speed at 941 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific card. It features 1344 SPUs along with 112 TAUs and 24 Rasterization Operator Units.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 870M should in theory be a lot faster than the GeForce GT 440 1.5GB in general. (explain)
Texel RateThe GeForce GTX 870M should be a lot (more or less 639%) more effective at AF than the GeForce GT 440 1.5GB. (explain)
Pixel RateThe GeForce GTX 870M should be much (approximately 58%) more effective at full screen anti-aliasing than the GeForce GT 440 1.5GB, and also will be capable of handling higher resolutions while still performing well. (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 data (measured in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, 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 most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
