In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 390X Gigabyte G1 Gaming 8GB Edition are significantly better than the AMD Radeon R9 380X.

The R9 390X has a 90 MHz higher core clock speed and 48 more Texture Mapping Units than the Radeon R9 380X. This results in the R9 390X providing 62.4 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 90 MHz higher core clock speed and 32 more Render Output Units than the Radeon R9 380X. This results in the R9 390X providing 36.8 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 Radeon R9 380X was released less than a year after the 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 R9 390X has 4096 MB more video memory than the Radeon R9 380X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 390X also has superior memory performance overall.

The R9 390X has 201.6 GB/sec greater memory bandwidth than the Radeon R9 380X, which means that the memory performance of the R9 390X is massively better than the Radeon R9 380X.

The Radeon R9 380X has 2048 Shader Processing Units and the Radeon R9 390X Gigabyte G1 Gaming 8GB Edition has 2816. However, the actual shader performance of the Radeon R9 380X is 1689 and the actual shader performance of the R9 390X is 2537. The R9 390X having 848 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 390X delivers a massively smoother and more efficient experience when processing graphical data than the Radeon R9 380X.

The Radeon R9 380X requires 190 Watts to run and the Radeon R9 390X Gigabyte G1 Gaming 8GB Edition requires 300 Watts. We would recommend a PSU with at least 500 Watts for the Radeon R9 380X and a PSU with at least 600 Watts for the R9 390X. The R9 390X requires 110 Watts more than the Radeon R9 380X to run. The difference is significant enough that the R9 390X may have an adverse affect on your yearly electricity bills in comparison to the Radeon R9 380X.

GPU Mini Review

Mini ReviewOverview
Radeon R9 380X 2GB is a Performance Graphics Card based on the Second Revision of the Graphics Core Next (GCN) Architecture.

Architecture
Radeon R9 380X equips the GPU Codenamed Antigua XT which is a GCN 1.2 GPU and has 32 Compute Units activated, offering 2048 Shader Processing Units, 128 TMUs and 32 ROPs.

GPU
The Central Unit is Clocked at 970MHz.

Memory: Speed
The GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 256-bit Memory Interface. The Memory Clock Operates at 1425MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 4GB.

Power Consumption
With a rated board TDP of 190W, it requires at least a 500W PSU with two available 6-pin connectors.

Performance
Essentially, Radeon R9 380X is a Power Optimized Radeon R9 280X. As of November 2015, Radeon R9 380X has no Direct Competitor because the awaited GeForce GTX 960 Ti is yet to be released.
Benchmarks Indicate Solid Performance at 1440p but Radeon R9 380X is still best suited for 1080p Gaming, as most modern demanding games will run with FPS ranging between 20 and 40 at 1440p.

System Suggestions
Radeon R9 380X is best suited for resolutions up to and including 1920x1080. We Recommend a Performance Processor and 8GB of RAM for Optimal Performance.
Overview
Radeon R9 390X Gigabyte G1 Gaming 8GB Edition is a Special Edition of AMD's High-End Radeon R9 390X, created by Gigabyte.

Overclock: Central Unit
The Central Unit is now of 1060MHz, instead of 1050MHz.

Overclock: Memory Clock
None.

Frame Buffer
Untouched.

Cooling Solution
WINDFORCE 2X Cooling System: The airflow is spilt through the triangle design at the fan edge, and is guided smoothly through the fan by special 3D stripe curve design. At the same time, it effectively enhanced the cooling capacity while reducing air turbulence.

Performance
Benchmarks Indicate no Performance Boost over the Reference Radeon R9 390X 8GB.
