In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M395X 4GB are very slightly better than the AMD Radeon R9 M390X 4GB.

The R9 M390X has a 177 MHz higher core clock speed than the R9 M395X, but the R9 M395X has 48 more Texture Mapping Units than the R9 M390X. As a result, the R9 M395X exhibits a 20.5 GTexel/s better Texture Fill Rate than the R9 M390X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R9 M390X has a 177 MHz higher core clock speed than the R9 M395X and the same number of Render Output Units. This results in the R9 M390X providing 5.7 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 M390X 4GB and the Radeon R9 M395X 4GB 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 M390X 4GB and the Radeon R9 M395X 4GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the Radeon R9 M390X 4GB and the Radeon R9 M395X 4GB are the same, which means the R9 M390X and the R9 M395X have equal limitations when it comes to graphical data transfer.

The Radeon R9 M390X 4GB has 1280 Shader Processing Units and the Radeon R9 M395X 4GB has 2048. However, the actual shader performance of the R9 M390X is 1034 and the actual shader performance of the R9 M395X is 1259. The R9 M395X having 225 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 M395X delivers a slightly smoother and more efficient experience when processing graphical data than the R9 M390X.

The Radeon R9 M390X 4GB requires 100 Watts to run and the Radeon R9 M395X 4GB requires 125 Watts. The R9 M395X requires 25 Watts more than the R9 M390X to run. The difference is not significant enough for the R9 M395X to have a noticeably larger impact on your yearly electricity bills than the R9 M390X.

GPU Mini Review

Mini ReviewOverview
Radeon R9 M390X 4GB is a High-End Mobile Graphics Card based on the Second Generation of the Graphics Core Next Architecture (GCN).

Architecture
Radeon R9 M390X 4GB Features a GPU Codenamed Neptune XT which is a Second Gen GCN GPU and is identical to the Curacao XT GPU used on the Desktop Radeon R9 270X.
Neptune XT has 20 Compute Units Unlocked and thus offers 1280 Shader Processing Units, 80 TMUs and 32 ROPs.

GPU
The Central Unit is Clocked at 900MHz and goes up to 950MHz, in Turbo Mode.

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 1250MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 4GB. Under most circumstances, this only proves useful in certain 3D Games whose Settings Require Large Amounts of Memory.
However, because the GPU itself is too weak to work under other circumstances in which 4GB of Memory are needed - such as 4K Gaming, a Large Frame Buffer is mostly a Gimmick.

Power Consumption
With a rated board TDP of 100W, it is suited for very large laptops.

Performance
Radeon R9 M390X 4GB is essentially a fast Radeon R9 M290X 4GB.
Performance is Comparable to the desktop Radeon HD 7870.

System Suggestions
Radeon R9 M390X 4GB is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
Overview

Architecture
Radeon R9 M395X 4GB Features a GPU Codenamed Amethyst XT which is a Third Gen GCN GPU and is identical to the Tonga XT GPU used on the Desktop Radeon R9 380X.
Amethyst XT has 32 Compute Units Unlocked and thus offers 2048 Shader Processing Units, 128 TMUs and 32 ROPs.

GPU
The Central Unit is Clocked at 723MHz.

Performance
Radeon R9 M395X 4GB is a Direct Rebrand of Radeon R9 M295X 4GB.
Performance is Comparable to the desktop Radeon R9 280. Therefore, even GeForce GTX 970M is still faster.

System Suggestions
Radeon R9 M395X 4GB is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
