In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M390X 4GB are significantly better than the Nvidia GeForce GTX 950M 2GB.

The GTX 950M has a 14 MHz higher core clock speed than the R9 M390X, but the R9 M390X has 40 more Texture Mapping Units than the GTX 950M. As a result, the R9 M390X exhibits a 35.4 GTexel/s better Texture Fill Rate than the GTX 950M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 950M has a 14 MHz higher core clock speed than the R9 M390X, but the R9 M390X has 16 more Render Output Units than the GTX 950M. As a result, the R9 M390X exhibits a 14.2 GPixel/s better Pixel Fill Rate than the GTX 950M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 M390X was released less than a year after the GTX 950M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The R9 M390X has 2048 MB more video memory than the GTX 950M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 M390X also has superior memory performance overall.

The R9 M390X has 80 GB/sec greater memory bandwidth than the GTX 950M, which means that the memory performance of the R9 M390X is much better than the GTX 950M.

The Radeon R9 M390X 4GB has 1280 Shader Processing Units and the GeForce GTX 950M 2GB has 640. However, the actual shader performance of the R9 M390X is 1034 and the actual shader performance of the GTX 950M is 858. The R9 M390X having 176 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 M390X delivers a massively smoother and more efficient experience when processing graphical data than the GTX 950M.

The Radeon R9 M390X 4GB requires 100 Watts to run and the GeForce GTX 950M 2GB requires 50 Watts. The R9 M390X requires 50 Watts more than the GTX 950M to run. The difference is significant enough that the R9 M390X may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 950M.

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).

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.

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.

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.
GeForce GTX 950M 2GB is a Performance Mobile Graphics Card based on the first variant of the Maxwell architecture.

The first variant of the Maxwell Architecture succeeds the Kepler Architecture. Despite being also manufactured with a 28nm technology, it has an extremely large L2 Cache which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

It equips a GPU codenamed GM107-N16P-GT which has 5 SM activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs. The central unit runs at 914MHz and goes up to 993MHz, in Turbo Mode.

The GPU accesses a 2GB frame buffer of fast GDDR5, through a 128-bit memory interface. The memory clock operates at 1253MHz. The size of the frame buffer is adequate.

DirectX 12 Support (11.0 Hardware Default) and support for GameStream, G-SYNC, GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Power Consumption
With a rated board TDP of 50W, it may be equipped in average sized notebooks.

Because GeForce GTX 950M 2GB is just a higher clocked GeForce GTX 850M v2 2GB, its performance is only about 5% faster than its predecessors and so GeForce GTX 860M 2GB is still faster.
Still, it still offers decent gaming at 1920x1080 and most modern games should run fluently at high settings.

System Suggestions
We recommend a strong processor (Intel Core i5 Mobile) and 8GB of RAM for a notebook with GeForce GTX 950M 2GB.
