Compare any two graphics cards:
Radeon R9 280 vs Radeon RX 470
IntroThe Radeon R9 280 features core clock speeds of 933 MHz on the GPU, and 1250 MHz on the 3072 MB of GDDR5 memory. It features 1792 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.
Compare all that to the Radeon RX 470, which comes with a clock speed of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also makes use of a 256-bit bus, and uses a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon R9 280 should be a little bit faster than the Radeon RX 470 in general. (explain)
Texel RateThe Radeon RX 470 should be a little bit (approximately 13%) faster with regards to texture filtering than the Radeon R9 280. (explain)
Pixel RateThe Radeon R9 280 is just a bit (approximately 1%) more effective at full screen anti-aliasing than the Radeon RX 470, and able to handle higher resolutions without losing too much performance. (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 maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This 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 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 number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
