In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 390 are significantly better than the AMD Radeon R9 380 PowerColor PCS+ 4GB Edition.

The Radeon R9 390 has a 20 MHz higher core clock speed and 48 more Texture Mapping Units than the R9 380. This results in the Radeon R9 390 providing 50.2 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 Radeon R9 390 has a 20 MHz higher core clock speed and 32 more Render Output Units than the R9 380. This results in the Radeon R9 390 providing 32.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

Both the Radeon R9 380 PowerColor PCS+ 4GB Edition and the Radeon R9 390 were released at the same time, so are likely to be quite similar.

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 390 has 4096 MB more video memory than the R9 380, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon R9 390 also has superior memory performance overall.

The Radeon R9 390 has 195.2 GB/sec greater memory bandwidth than the R9 380, which means that the memory performance of the Radeon R9 390 is massively better than the R9 380.

The Radeon R9 380 PowerColor PCS+ 4GB Edition has 1792 Shader Processing Units and the Radeon R9 390 has 2560. However, the actual shader performance of the R9 380 is 1493 and the actual shader performance of the Radeon R9 390 is 2176. The Radeon R9 390 having 683 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R9 390 delivers a massively smoother and more efficient experience when processing graphical data than the R9 380.

The Radeon R9 380 PowerColor PCS+ 4GB Edition requires 190 Watts to run and the Radeon R9 390 requires 275 Watts. We would recommend a PSU with at least 500 Watts for the R9 380 and a PSU with at least 600 Watts for the Radeon R9 390. The Radeon R9 390 requires 85 Watts more than the R9 380 to run. The difference is significant enough that the Radeon R9 390 may have an adverse affect on your yearly electricity bills in comparison to the R9 380.

GPU Mini Review

Mini ReviewOverview
Radeon R9 380 PowerColor PCS+ 4GB Edition is a Special Edition of AMD's Performance Radeon R9 380, created by PowerColor.

Overclock: Central Unit
The Central Unit is now of 980MHz, instead of 970MHz.

Overclock: Memory Clock
The Operating Memory Clock is now of 1475MHz, instead of 1375MHz.

Frame Buffer
The Frame Buffer was doubled to 4GB: a gimmick which doesn't yield any performance boost and can be considered marketing to lure consumers into paying more for the same product.


Cooling Solution
PCS-Professional Cooling System: The unique cooling technology can decrease operating environment temp. Effectively, and enhance headroom for OC capabilities.

Performance
Benchmarks Indicate a 1% Performance Boost over the Reference Radeon R9 380.
Overview
Radeon R9 390 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 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.

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 275W, it requires at least a 750W PSU with one available 6-pin and one available 8-pin connectors.

Performance
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.

System Suggestions
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.
