Compare any two graphics cards:
Radeon R9 390X 8G vs Radeon RX 580
IntroThe Radeon R9 390X 8G features a core clock frequency of 1050 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 512-bit memory bus, and makes use of a 28 nm design. It is made up of 2816 SPUs, 176 TAUs, and 64 Raster Operation Units.Compare all that to the Radeon RX 580, which features a core clock frequency of 1257 MHz and a GDDR5 memory speed of 2000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 14 nm design. It features 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 390X 8G should theoretically be much faster than the Radeon RX 580 overall. (explain)
Texel RateThe Radeon R9 390X 8G will be a bit (about 2%) faster with regards to anisotropic filtering than the Radeon RX 580. (explain)
Pixel RateThe Radeon R9 390X 8G should be a lot (about 67%) better at AA than the Radeon RX 580, and also capable of handling 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 can be applied per second. This number is worked out by multiplying the total number of texture units by the core 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 applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

One Response to “Radeon R9 390X 8G vs Radeon RX 580”I have them both.
The 390 is a dual dissipation and the 580 is a triple dissipation model.
While the 580 obviously has an edge with three fans, my 390 runs pretty hot. But its actually considered normal for the card.
I'm liking the 580 design more, it can take the punishment but it has 256 vs 512 bus speed. This cut down is also what allows the 580 to stay cooler, but as a consequence you get 32 rops instead of 64 vs the 390.
It's much easier to overclock the 580 in case anyone is wondering. If you do pick one up make sure to get the triple dissipation model, dual models are not worth it. You obviously need a mid tower for this fyi. It uses a single connector vs the double for the 390.
The card currently comes in two distinct models one is their OC line the other is for 4k users, which is kind of stupid but that's how their selling it. I OC mine by 20% (4000mhz) it stays stable and quite around 50-60c in fact you don't notice much of a difference.
