In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M395X 4GB are very slightly better than the Nvidia GeForce GTX 880M 8GB.

The GTX 880M has a 231 MHz higher core clock speed and the same number of Texture Mapping Units as the R9 M395X. This results in the GTX 880M providing 29.6 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 GTX 880M has a 231 MHz higher core clock speed than the R9 M395X and the same number of Render Output Units. This results in the GTX 880M providing 7.4 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 M395X was released over a year more recently than the GTX 880M, and so the R9 M395X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 880M.

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 GTX 880M has 4096 MB more video memory than the R9 M395X, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The memory bandwidth of the Radeon R9 M395X 4GB and the GeForce GTX 880M 8GB are the same, which means the R9 M395X and the GTX 880M have equal limitations when it comes to graphical data transfer.

The Radeon R9 M395X 4GB has 2048 Shader Processing Units and the GeForce GTX 880M 8GB has 1536. However, the actual shader performance of the R9 M395X is 1259 and the actual shader performance of the GTX 880M is 1525. The GTX 880M having 266 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 880M delivers a marginally 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 GeForce GTX 880M 8GB requires 122 Watts. The R9 M395X requires 3 Watts more than the GTX 880M 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 GTX 880M.

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.
GeForce GTX 880M 8GB is a high-end mobile graphics card and the fastest as of Spring 2014.
It is based on a full variant of the GK104 Core of the 28nm Kepler architecture and thus offers 1536 Shader Processing Units, 128 TMUs and 32 ROPs, on a 256-bit memory interface of fast GDDR5. While the central unit runs at 954MHz and goes up to 993MHz, in Turbo Mode, the memory clock operates at 1250MHz. The rated TDP is clearly above 100W and 122W, on average.
It is thus just a faster clocked GeForce GTX 780M. Theoretically, its performance might be up to 15% better than its predecessors, but since its memory bandwidth remains the same, expect at most a 10% performance boost, depending on the 3D Game.
Therefore, GeForce GTX 880M will only be seen on very large note books and it needs to be paired with at least 8GB of RAM and a Strong Quad Core. The card is suited for 1080p and even the most demanding games should run fluently at high settings.
