Compare any two graphics cards:
Radeon R9 390 8G vs Radeon R9 390X 8G
IntroThe Radeon R9 390 8G comes with a core clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 512-bit bus, and uses a 28 nm design. It features 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.Compare that to the Radeon R9 390X 8G, which uses a 28 nm design. AMD has set the core frequency at 1050 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this specific model. It features 2816 SPUs along with 176 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have the exact same bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe Radeon R9 390X 8G is just a bit (approximately 16%) faster with regards to anisotropic filtering than the Radeon R9 390 8G. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 390X 8G is superior to the Radeon R9 390 8G, but 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
