Radeon R9 390 Game Requirement Analysis
Radeon R9 390 is a High-End Graphics Card based on the First Revision of the Graphics Core Next (GCN) 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.
It equips a GPU Codenamed Grenada PRO which has 60 Compute Units activated and thus offers 2560 Shader Processing Units, 160 TMUs and 64 ROPs. The Central Unit is clocked at 1000MHz.
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.
With a rated board TDP of 275W, it requires at least a 750W PSU with one available 6-pin and one available 8-pin connectors.
Radeon R9 390 8GB competes with GeForce GTX 970 and is essentially a Higher Clocked Radeon R9 290 with the addition of twice as much video memory (8GB against 4GB).
It proves to be slower than GeForce GTX 970 at resolutions up to 1920x1080 but takes the lead beyond that.
However, the lack of DirectX 12.1 Support paired with the enormous Power Consumption (almost twice as much as GeForce GTX 970) and the Gimmicked 8GB Frame Buffer, makes it an extremely uncompetitive product.
Radeon R9 390 is best suited for resolutions up to and including 2560x1440. We recommend a Very Strong Processor and 8GB of RAM for Optimal Performance.
