Compare any two graphics cards:
GeForce 820M vs GeForce 920M
IntroThe GeForce 820M has a core clock frequency of 719 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit bus, and uses a 28 nm design. It features 96 SPUs, 16 TAUs, and 4 ROPs.Compare all of that to the GeForce 920M, which uses a 28 nm design. nVidia has set the core frequency at 954 MHz. The DDR3 memory works at a speed of 900 MHz on this specific card. It features 384 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce 820M is 11% faster than the GeForce 920M overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce 920M should be quite a bit (more or less 165%) better at texture filtering than the GeForce 820M. (explain)
Pixel RateThe GeForce 920M should be a lot (approximately 165%) better at anti-aliasing than the GeForce 820M, and able to handle higher screen 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
