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 380 (OEM).

The R9 390X has a 142 MHz higher core clock speed and 64 more Texture Mapping Units than the R9 380. This results in the R9 390X providing 83.8 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 142 MHz higher core clock speed and 32 more Render Output Units than the R9 380. This results in the R9 390X providing 38.4 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 R9 380, 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 6144 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 R9 390X also has superior memory performance overall.

The R9 390X has 208 GB/sec greater memory bandwidth than the R9 380, which means that the memory performance of the R9 390X is massively better than the R9 380.

The Radeon R9 390X Gigabyte G1 Gaming 8GB Edition has 2816 Shader Processing Units and the Radeon R9 380 (OEM) has 1792. However, the actual shader performance of the R9 390X is 2537 and the actual shader performance of the R9 380 is 1398. The R9 390X having 1139 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 R9 380.

The Radeon R9 390X Gigabyte G1 Gaming 8GB Edition requires 300 Watts to run and the Radeon R9 380 (OEM) requires 190 Watts. We would recommend a PSU with at least 600 Watts for the R9 390X and a PSU with at least 500 Watts for the R9 380. The R9 390X requires 110 Watts more than the R9 380 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 R9 380.

GPU Mini Review

Mini ReviewOverview
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.
Overview
Radeon R9 380 (OEM) is an OEM only, Performance Graphics Card based on the second revision of the Graphics Core Next Architecture.

Architecture
The GCN 1.2 revision of the Graphics Core Next Architecture improves memory bandwidth performance which allows AMD to produce Graphics Cards with smaller data transfer rates without causing too much impact on the overall performance. This is done by using lossless delta color compression.
GCN 1.2 also adds improved Tesselation and video encoding/decoding performance as well as DirectX 12.0 Support.

GPU
It equips a GPU codenamed Tonga PRO which is essentially a cut-down version of the Tahiti PRO GPU previously used on Radeon HD 7950. It offers 1792 Shader Processing Units, 112 TMUs and 32 ROPs. The central unit runs at 918MHz.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1375MHz.

Features
DirectX 12.0 Support (11.0 Hardware Default) and support for Crossfire, Mantle, PowerTune, TrueAudio, Eyefinity, ZeroCore, HD3D, App Acceleration and other technologies.

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

Performance
Radeon R9 380 (OEM) is a direct rebrand of Radeon R9 285. Therefore, it offers exactly the same performance.
Gaming benchmarks prove that at 1080p (1920x1080) Radeon R9 380 (OEM) is almost as fast as GeForce GTX 670 and surpasses GeForce GTX 760 considerably.

System Suggestions
We recommend a decent Quad Core Processor (Intel Core i5 Quad Core/AMD FX Six Core) and 8GB of RAM for a system with Radeon R9 380 (OEM).
