Compare any two graphics cards:
Radeon HD 7950 vs Radeon RX 470
IntroThe Radeon HD 7950 comes with a GPU core clock speed of 800 MHz, and the 1536 MB of GDDR5 RAM runs at 1250 MHz through a 384-bit bus. It also features 1792 SPUs, 112 TAUs, and 32 ROPs.
Compare all that to the Radeon RX 470, which has a clock frequency of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also uses a 256-bit memory bus, and makes use of a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 7950 should be 14% quicker than the Radeon RX 470 in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon RX 470 should be much (approximately 32%) better at AF than the Radeon HD 7950. (explain)
Pixel RateThe Radeon RX 470 will be a bit (about 16%) faster with regards to AA than the Radeon HD 7950, and also 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.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
