Compare any two graphics cards:
Radeon HD 3850 1GB vs Radeon RX 580
IntroThe Radeon HD 3850 1GB has a GPU core speed of 668 MHz, and the 1024 MB of GDDR3 memory runs at 828 MHz through a 256-bit bus. It also is made up of 320(64x5) Stream Processors, 16 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon RX 580, which makes use of a 14 nm design. AMD has set the core frequency at 1257 MHz. The GDDR5 RAM runs at a frequency of 2000 MHz on this specific model. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon RX 580 will be 395% faster than the Radeon HD 3850 1GB in general, because of its higher data rate. (explain)
Texel RateThe Radeon RX 580 should be much (approximately 1594%) better at AF than the Radeon HD 3850 1GB. (explain)
Pixel RateThe Radeon RX 580 will be much (approximately 276%) more effective at anti-aliasing than the Radeon HD 3850 1GB, and also should be able to handle higher screen resolutions more effectively. (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 information (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must 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 anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
