Compare any two graphics cards:
Radeon R9 290 vs Radeon R9 390 8G
IntroThe Radeon R9 290 has a core clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 512-bit memory bus, and makes use of a 28 nm design. It features 2560 SPUs, 160 TAUs, and 64 ROPs.Compare those specifications to the Radeon R9 390 8G, which comes with a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 512-bit memory bus, and makes use of a 28 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 390 8G is 20% quicker than the Radeon R9 290 in general, because of its higher bandwidth. (explain)
Texel RateThe Radeon R9 390 8G should be a lot (approximately 25%) more effective at texture filtering than the Radeon R9 290. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 390 8G is superior to the Radeon R9 290, and very much so. (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 largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
