Compare any two graphics cards:
Radeon HD 6970 vs Radeon RX 470
IntroThe Radeon HD 6970 makes use of a 40 nm design. AMD has set the core speed at 880 MHz. The GDDR5 RAM is set to run at a speed of 1375 MHz on this specific card. It features 1536 SPUs along with 96 Texture Address Units and 32 ROPs.
Compare all of that to the Radeon RX 470, which has GPU clock speed of 926 MHz, and 8192 MB of GDDR5 RAM set to run at 1650 MHz through a 256-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 470, in theory, should be a bit faster than the Radeon HD 6970 in general. (explain)
Texel RateThe Radeon RX 470 will be quite a bit (approximately 40%) more effective at texture filtering than the Radeon HD 6970. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon RX 470 is superior to the Radeon HD 6970, though not 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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should 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 high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
