In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 940MX 2GB are massively better than the AMD Radeon HD 8240.

The GeForce 940MX 2GB has a 722 MHz higher core clock speed and 16 more Texture Mapping Units than the Radeon HD 8240. This results in the GeForce 940MX 2GB providing 23.7 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 GeForce 940MX 2GB has a 722 MHz higher core clock speed and 4 more Render Output Units than the Radeon HD 8240. This results in the GeForce 940MX 2GB 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 GeForce 940MX 2GB was released over a year more recently than the Radeon HD 8240, and so the GeForce 940MX 2GB is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 8240.

The GeForce 940MX 2GB has 2048 MB video memory, but the Radeon HD 8240 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 940MX 2GB has 384 Shader Processing Units and the Radeon HD 8240 has 128. However, the actual shader performance of the GeForce 940MX 2GB is 644 and the actual shader performance of the Radeon HD 8240 is 33. The GeForce 940MX 2GB having 611 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 940MX 2GB delivers a noticeably smoother and more efficient experience when processing graphical data than the Radeon HD 8240.

The GeForce 940MX 2GB requires 25 Watts to run and the Radeon HD 8240 requires 15 Watts. The GeForce 940MX 2GB requires 10 Watts more than the Radeon HD 8240 to run. The difference is not significant enough for the GeForce 940MX 2GB to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 8240.

GPU Mini Review

Mini ReviewOverview
GeForce 940MX 2GB is a Middle-Class Mobile Graphics Card based on the Maxwell Architecture.

Architecture
GeForce 940MX 2GB Features a GPU Codenamed GM108-N16S-GTR which is a First Gen Maxwell GPU and is identical to the GM108-N16S-GT-S used on GeForce 940M but with the addition of GDDR5 Support.
GM108-N16S-GTR has 3 Compute Units Unlocked and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs.

GPU
The Central Unit is Clocked at 1122Hz and goes up to 1242MHz, in Turbo Mode.

Memory: Speed
The GPU is equipped with DDR3 and Accesses the Frame Buffer through a 64-bit Memory Interface. The Memory Clock Operates at 1001MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 2GB.

Power Consumption
With a rated board TDP of 25W, it is suited for small and medium sized laptops.

Performance
Equipped with DDR3, GeForce GT 940MX is only slightly faster than GeForce GT 940M.

System Suggestions
GeForce 940MX 2GB is best suited for resolutions up to and including 1366x768. We Recommend a Middle-Class Processor and 8GB of RAM for Optimal Performance.
Radeon HD 8240 is an integrated graphics card on some of the Kabini APUs.
It is based on the Graphics Core Next Architecture and shares the main system memory of up to 667MHz, on a 128-bit memory interface, whereas the memory bandwidth and performance will depend heavily on the laptop configuration.
The codenamed Kalindi Core offers 128 Shader Processing Units, 8 TMUs and 4 ROPs.
Assuming the best combination possible, expect performance similar to an Intel HD 3000 and never below an Intel HD 2500. Thus, the card is only suited for modest 3D games and titles like BF4, AC4 and CoD: Ghosts are unplayable.
