In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 480X 4GB are massively better than the Nvidia GeForce GT 940 2GB.

The GT 940 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The RX 480X was released less than a year after the GT 940, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The RX 480X has 2048 MB more video memory than the GT 940, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GT 940 has superior memory performance.

The GT 940 has 80 GB/sec greater memory bandwidth than the RX 480X, which means that the memory performance of the GT 940 is much better than the RX 480X.

The Radeon RX 480X 4GB has 4096 Shader Processing Units and the GeForce GT 940 2GB has 512. However, the actual shader performance of the RX 480X is 5325 and the actual shader performance of the GT 940 is 0. The RX 480X having 5325 better shader performance and an altogether better performance when taking into account other relevant data means that the RX 480X delivers a massively smoother and more efficient experience when processing graphical data than the GT 940.

The RX 480X transistor size technology is 14 nm (nanometers) smaller than the GT 940. This means that the RX 480X is expected to run slightly cooler and achieve higher clock frequencies than the GT 940.

The Radeon RX 480X 4GB requires 175 Watts to run and the GeForce GT 940 2GB requires 60 Watts. We would recommend a PSU with at least 500 Watts for the RX 480X and a PSU with at least 300 Watts for the GT 940. The RX 480X requires 115 Watts more than the GT 940 to run. The difference is significant enough that the RX 480X may have an adverse affect on your yearly electricity bills in comparison to the GT 940.

GPU Mini Review

Mini ReviewOverview
Radeon RX 480X 4GB is an Upcoming High-End Graphics Card based on the Third Revision of the Graphics Core Next (GCN) Architecture.

Architecture
N/A.

GPU
N/A.

Memory
The GPU accesses a 4GB frame buffer of Second Generation HBM, through a 4096-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 500MHz.

Power Consumption
N/A.

Performance
N/A.

System Suggestions
Radeon RX 480X 4GB is best suited for resolutions up to and including 2560x1600. We recommend a High-End Processor and 8GB of RAM for Optimal Performance.
Overview
GeForce GT 940 2GB is an upcoming middle-class Graphics Card based on the first revision of the Maxwell architecture.

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.

GPU
It equips a GPU codenamed ???? which has 8 SM activated and thus offers 512 Shader Processing Units, 32 TMUs and 16 ROPs, on a 128-bit memory interface of fast GDDR5. The central unit runs at XXXXMHz and goes up to XXXXMHz, in Turbo Mode, while the memory clock operates at 1250MHz.

Features
DirectX 12.0 Support (11.0 Hardware Default) and support for GameStream, G-SYNC, GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Cooling Solution
Coming Soon!

Power Consumption
With a rated board TDP of 60W, it requires at least a 300W PSU and relies entirely on the PCI Slot for power.
