In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 390X are very slightly better than the AMD Radeon R9 390X PowerColor Devil 8GB Edition.
The R9 390X has a 50 MHz higher core clock speed and the same number of Texture Mapping Units as the Radeon R9 390X. This results in the R9 390X providing 8.8 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The R9 390X has a 50 MHz higher core clock speed than the Radeon R9 390X and the same number of Render Output Units. This results in the R9 390X providing 3.2 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The R9 390X was released less than a year after the Radeon R9 390X, and so they are likely to have similar driver support for optimizing performance when running the latest games.
Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.
The Radeon R9 390X PowerColor Devil 8GB Edition and the Radeon R9 390X have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The R9 390X has 6.4 GB/sec greater memory bandwidth than the Radeon R9 390X, which means that the memory performance of the R9 390X is marginally better than the Radeon R9 390X.
Both the Radeon R9 390X PowerColor Devil 8GB Edition and the Radeon R9 390X have 2816 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the R9 390X has 8.8 GTexel/s better Texture Fill Rate, 3.2 GPixel/s better Pixel Fill Rate, and 6.4 GB/sec greater memory bandwidth, so should have a marginally faster performance than the Radeon R9 390X.
The Radeon R9 390X PowerColor Devil 8GB Edition requires 275 Watts to run and the Radeon R9 390X requires 275 Watts. We would recommend a PSU with at least 750 Watts for the R9 390X and a PSU with at least 600 Watts for the Radeon R9 390X. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

| Mini Review | Overview Radeon R9 390X PowerColor Devil 8GB Edition is a Special Edition of AMD's High-End Radeon R9 390X, created by PowerColor. Overclock: Central Unit The Central Unit is now of 1100MHz, instead of 1050MHz. Overclock: Memory Clock The Operating Memory Clock is now of 1525MHz, instead of 1500MHz. Frame Buffer Untouched. Cooling Solution Hybrid Cooling: Combine both air-cooling and watercooling to one perfect hybrid system to maintain higher over clock performance with lower temperature. Performance Benchmarks Indicate a 2% Performance Boost over the Reference Radeon R9 390X 8GB. | Overview Radeon R9 390X is a High-End Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture. Architecture The GCN 1.1 revision of the Graphics Core Next Architecture adds new important technologies and is largely oriented for energy efficiency. New technologies such as PowerTune and TrueAudio are the biggest additions as well as DirectX 11.2 support. GPU It equips a GPU Codenamed Grenada XT which has 44 Compute Units activated and thus offers 2816 Shader Processing Units, 176 TMUs and 64 ROPs. The Central Unit is clocked at 1050MHz. Memory The GPU accesses a 8GB frame buffer of fast GDDR5, through a 512-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1500MHz. Power Consumption With a rated board TDP of 290W, it requires at least a 750W PSU with one available 6-pin and one available 8-pin connectors. Performance Radeon R9 390X competes with GeForce GTX 980 and is essentially a Higher Clocked Radeon R9 290X with the addition of twice as much video memory (8GB against 4GB). Its Performance lies somewhere between GeForce GTX 970 and GeForce GTX 980, as does its price. However, the lack of DirectX 12.1 Support paired with the enormous Power Consumption (almost twice as much as GeForce GTX 980) and the Gimmicked 8GB Frame Buffer, makes it an extremely uncompetitive product. Still, Radeon R9 390X 8GB is around $120 cheaper than GeForce GTX 980 and performs reasonably better at 4K, though it is still best suited for 2560x1600. System Suggestions Radeon R9 390X is best suited for resolutions up to and including 2560x1600. We recommend a Very Strong Processor and 8GB of RAM for Optimal Performance. | |||
