Compare any two graphics cards:
Radeon HD 7950 3GB vs Radeon RX 480
IntroThe Radeon HD 7950 3GB uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory works at a speed of 1250 MHz on this model. It features 1792 SPUs along with 112 TAUs and 32 ROPs.Compare those specs to the Radeon RX 480, which features a GPU core clock speed of 1120 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also is made up of 2304 Stream Processors, 144 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon RX 480 is 9% quicker than the Radeon HD 7950 3GB in general, because of its higher data rate. (explain)
Texel RateThe Radeon RX 480 is much (about 80%) faster with regards to AF than the Radeon HD 7950 3GB. (explain)
Pixel RateThe Radeon RX 480 should be much (more or less 40%) faster with regards to full screen anti-aliasing than the Radeon HD 7950 3GB, and also should be capable of handling 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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
