Compare any two graphics cards:
Radeon HD 7950 3GB vs Radeon RX 480
IntroThe Radeon HD 7950 3GB features a GPU core clock speed of 800 MHz, and the 3072 MB of GDDR5 RAM runs at 1250 MHz through a 384-bit bus. It also features 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.Compare those specs to the Radeon RX 480, which uses a 14 nm design. AMD has set the core speed at 1120 MHz. The GDDR5 RAM runs at a frequency of 2000 MHz on this specific model. It features 2304 SPUs along with 144 TAUs and 32 ROPs.

Zcash Mining Hash Rate
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon RX 480 will be 9% faster than the Radeon HD 7950 3GB overall, due to its greater data rate. (explain)
Texel RateThe Radeon RX 480 should be a lot (about 80%) more effective at anisotropic filtering than the Radeon HD 7950 3GB. (explain)
Pixel RateThe Radeon RX 480 will be much (approximately 40%) more effective at full screen anti-aliasing than the Radeon HD 7950 3GB, and will be able to handle higher 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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
