Compare any two graphics cards:
GeForce 820M vs Radeon R9 Nano
IntroThe GeForce 820M has a GPU core speed of 719 MHz, and the 2048 MB of DDR3 memory runs at 1000 MHz through a 64-bit bus. It also features 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.Compare those specs to the Radeon R9 Nano, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The HBM memory runs at a speed of 500 MHz on this specific model. It features 4096 SPUs as well as 256 Texture Address Units and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 Nano should be quite a bit faster than the GeForce 820M overall. (explain)
Texel RateThe Radeon R9 Nano will be quite a bit (approximately 2125%) faster with regards to AF than the GeForce 820M. (explain)
Pixel RateThe Radeon R9 Nano should be a lot (more or less 2125%) more effective at FSAA than the GeForce 820M, and also will be 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 max amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
