Compare any two graphics cards:
GeForce GT 420 vs Radeon RX 560
IntroThe GeForce GT 420 comes with a clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It features 48 SPUs, 8 Texture Address Units, and 4 ROPs.Compare those specifications to the Radeon RX 560, which features a clock speed of 1175 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit bus, and makes use of a 14 nm design. It is made up of 1024 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon RX 560 should in theory be much superior to the GeForce GT 420 overall. (explain)
Texel RateThe Radeon RX 560 should be a lot (more or less 1243%) better at anisotropic filtering than the GeForce GT 420. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon RX 560 is the winner, and very much so. (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 (measured in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
