In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M365X 4GB are noticeably better than the Nvidia GeForce 840M 2GB.

The GeForce 840M 2GB has a 404 MHz higher core clock speed than the R9 M365X, but the R9 M365X has 16 more Texture Mapping Units than the GeForce 840M 2GB. As a result, the R9 M365X exhibits a 0.3 GTexel/s better Texture Fill Rate than the GeForce 840M 2GB. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce 840M 2GB has a 404 MHz higher core clock speed than the R9 M365X, but the R9 M365X has 8 more Render Output Units than the GeForce 840M 2GB. As a result, the R9 M365X exhibits a 1.8 GPixel/s better Pixel Fill Rate than the GeForce 840M 2GB. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 M365X was released over a year more recently than the GeForce 840M 2GB, and so the R9 M365X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 840M 2GB.

The R9 M365X has 2048 MB more video memory than the GeForce 840M 2GB, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 M365X also has superior memory performance overall.

The R9 M365X has 48 GB/sec greater memory bandwidth than the GeForce 840M 2GB, which means that the memory performance of the R9 M365X is noticeably better than the GeForce 840M 2GB.

The Radeon R9 M365X 4GB has 640 Shader Processing Units and the GeForce 840M 2GB has 384. However, the actual shader performance of the R9 M365X is 340 and the actual shader performance of the GeForce 840M 2GB is 583. The GeForce 840M 2GB having 243 better shader performance is not particularly notable, as altogether the R9 M365X performs better when taking into account other relevant data.

The Radeon R9 M365X 4GB requires 50 Watts to run and the GeForce 840M 2GB requires 33 Watts. The R9 M365X requires 17 Watts more than the GeForce 840M 2GB to run. The difference is not significant enough for the R9 M365X to have a noticeably larger impact on your yearly electricity bills than the GeForce 840M 2GB.

GPU Mini Review

Mini ReviewOverview
Radeon R9 M365X 4GB is a Fast-Middle-Class Mobile Graphics Card based on the First Generation of the Graphics Core Next Architecture (GCN).



Architecture
Radeon R9 M365X 4GB Features a GPU Codenamed Venus PRO which is a First Gen GCN GPU and is identical to the Cape GPU used on the Desktop Radeon R7 250X.
Venus PRO has 10 Compute Units Unlocked and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs.

GPU
The Central Unit is Clocked at 625MHz.

Memory: Speed
The GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 128-bit Memory Interface. The Memory Clock Operates at 1000MHz.

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 50W, it is suited for large laptops.

Performance
Radeon R9 M365X 4GB is a Direct Rebrand of Radeon R9 M265X.
Performance is Comparable to the Desktop Radeon R7 250.

System Suggestions
Radeon R9 M365X 4GB is best suited for resolutions up to and including 1600x900. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
Overview
GeForce 840M 2GB is a Middle-Class Mobile Graphics Card based on the First Revision of the Maxwell architecture.

Architecture
The Maxwell architecture features many improvements and among them is the 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.

GPU
It equips a GPU codenamed GM108 which has 3 SM activated and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The central unit runs at 1029MHz and goes up to 1124MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 64-bit memory interface. The Frame Buffer is exaggerated and in no way benefits the GPU. The memory clock operates at 1001MHz.

Features
DirectX 11.2 Support (11.0 Hardware Default) and support for GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Power Consumption
With a rated board TDP of 33W, it will only be equipped in average sized notebooks.

Performance
Benchmarks indicate its performance is over 20% faster than the older GeForce GT 740M. Therefore, it should match GeForce GT 750M.

System Suggestions
We recommend a modest processor (Intel Core i5 Mobile) and 4GB of RAM for a notebook with GeForce 840M 2GB.
