In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7970M Crossfire are very slightly better than the AMD Radeon R9 M395X 4GB.

The HD 7970M has a 127 MHz higher core clock speed and 32 more Texture Mapping Units than the R9 M395X. This results in the HD 7970M providing 43.5 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 HD 7970M has a 127 MHz higher core clock speed and 32 more Render Output Units than the R9 M395X. This results in the HD 7970M providing 31.3 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 M395X was released over three years more recently than the HD 7970M, and so the R9 M395X is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 7970M 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 Radeon R9 M395X 4GB and the Radeon HD 7970M Crossfire have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 7970M has 147.2 GB/sec greater memory bandwidth than the R9 M395X, which means that the memory performance of the HD 7970M is massively better than the R9 M395X.

The Radeon R9 M395X 4GB has 2048 Shader Processing Units and the Radeon HD 7970M Crossfire has 2560. However, the actual shader performance of the R9 M395X is 1259 and the actual shader performance of the HD 7970M is 1850. The HD 7970M having 591 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7970M delivers a massively smoother and more efficient experience when processing graphical data than the R9 M395X.

The Radeon R9 M395X 4GB requires 125 Watts to run and the Radeon HD 7970M Crossfire requires 200 Watts. The HD 7970M requires 75 Watts more than the R9 M395X to run. The difference is significant enough that the HD 7970M may have an adverse affect on your yearly electricity bills in comparison to the R9 M395X.

GPU Mini Review

Mini ReviewOverview
Radeon R9 M395X 4GB is a High-End Mobile Graphics Card based on the second revision of the Graphics Core Next Architecture (CGN).

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.

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 125W, it is suited for very large laptops.

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.
Radeon HD 7970M Crossfire is a solution of two Radeon HD 7970M put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7970M to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to twice as better as a single Radeon HD 7970M performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon HD 7970M.
Even the most demanding games will run at the highest settings.
