Compare any two graphics cards:
GeForce 930M vs GeForce GT 315
IntroThe GeForce 930M comes with a clock speed of 928 MHz and a DDR3 memory frequency of 900 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.Compare all of that to the GeForce GT 315, which has GPU clock speed of 625 MHz, and 512 MB of DDR3 RAM running at 790 MHz through a 128-bit bus. It also is comprised of 48 Stream Processors, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the GeForce GT 315 should be much faster than the GeForce 930M in general. (explain)
Texel RateThe GeForce 930M should be quite a bit (approximately 123%) more effective at texture filtering than the GeForce GT 315. (explain)
Pixel RateThe GeForce 930M should be quite a bit (approximately 48%) more effective at AA than the GeForce GT 315, and will be able to handle higher resolutions without slowing down too much. (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 (measured in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once 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 high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed 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 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 that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
