Compare any two graphics cards:
Radeon HD 7950 3GB vs Radeon RX 580
IntroThe Radeon HD 7950 3GB has a clock speed of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 384-bit bus, and makes use of a 28 nm design. It is comprised of 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.Compare those specs to the Radeon RX 580, which features a clock speed of 1257 MHz and a GDDR5 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 14 nm design. It features 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Zcash Mining Hash Rate
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon RX 580 should be 9% quicker than the Radeon HD 7950 3GB in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon RX 580 will be much (more or less 102%) faster with regards to AF than the Radeon HD 7950 3GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon RX 580 is the winner, by far. (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 (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
