Compare any two graphics cards:
GeForce 830M vs GeForce GTX 970M
IntroThe GeForce 830M has a clock speed of 1029 MHz and a DDR3 memory frequency of 900 MHz. It also features a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 256 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare all that to the GeForce GTX 970M, which uses a 28 nm design. nVidia has clocked the core frequency at 924 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this specific card. It features 1280 SPUs along with 80 TAUs and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 970M will be 567% faster than the GeForce 830M overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 970M is much (approximately 349%) more effective at AF than the GeForce 830M. (explain)
Pixel RateThe GeForce GTX 970M should be a lot (more or less 439%) faster with regards to full screen anti-aliasing than the GeForce 830M, and also will be capable of handling higher resolutions without losing too much performance. (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 largest amount of data (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
