Compare any two graphics cards:
Radeon R9 390X 8G vs Radeon RX 580
IntroThe Radeon R9 390X 8G makes use of a 28 nm design. AMD has clocked the core speed at 1050 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this particular model. It features 2816 SPUs along with 176 TAUs and 64 ROPs.
Compare those specifications to the Radeon RX 580, which comes with GPU core speed of 1257 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Theoretically speaking, the Radeon R9 390X 8G should perform quite a bit faster than the Radeon RX 580 overall. (explain)
Texel RateThe Radeon R9 390X 8G will be a bit (more or less 2%) more effective at anisotropic filtering than the Radeon RX 580. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 390X 8G is superior to the Radeon RX 580, 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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling 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 video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 ability to reach the max fill rate.
