In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 540X 4GB Mobile are marginally better than the Nvidia GeForce GTX 675M SLI.

The RX 540X has a 504 MHz higher core clock speed than the GTX 675M, but the GTX 675M has 96 more Texture Mapping Units than the RX 540X. As a result, the GTX 675M exhibits a 43.4 GTexel/s better Texture Fill Rate than the RX 540X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 540X has a 504 MHz higher core clock speed than the GTX 675M, but the GTX 675M has 48 more Render Output Units than the RX 540X. As a result, the GTX 675M exhibits a 21.7 GPixel/s better Pixel Fill Rate than the RX 540X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 540X was released over three years more recently than the GTX 675M, and so the RX 540X is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 675M when running the latest games.

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 Radeon RX 540X 4GB Mobile and the GeForce GTX 675M SLI have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 675M has 192 GB/sec greater memory bandwidth than the RX 540X, which means that the memory performance of the GTX 675M is massively better than the RX 540X.

The Radeon RX 540X 4GB Mobile has 512 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the RX 540X is 624 and the actual shader performance of the GTX 675M is 952. The GTX 675M having 328 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 675M delivers a massively smoother and more efficient experience when processing graphical data than the RX 540X.

The RX 540X transistor size technology is 26 nm (nanometers) smaller than the GTX 675M. This means that the RX 540X is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M. While they exhibit similar graphical performance, the RX 540X should consume less power than the GTX 675M.

The Radeon RX 540X 4GB Mobile requires 50 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. We would recommend a PSU with at least 350 Watts for the RX 540X. The GTX 675M requires 150 Watts more than the RX 540X to run. The difference is significant enough that the GTX 675M may have an adverse affect on your yearly electricity bills in comparison to the RX 540X.

GPU Mini Review

Mini ReviewOverview
The new AMD Radeon RX 500X series are an OEM version of the current RX 500 series. The Radeon RX 540X 4GB Mobile is a Low to Middle-Class laptop Graphics Card based on the 4th Generation of the Graphics Core Next (GCN) Architecture. The specs of the Radeon RX 500X series graphics cards are identical to the standard Radeon RX 500 series.

GPU
It equips a GPU Codenamed Lexa Pro which has 14 Compute Units activated and thus 512 Shader Processing Units, 32 TMUs and 16 ROPs.

Memory
The GPU accesses a 4GB frame buffer of Fast GDDR5, through a 128-bit memory interface, while the Memory Clock Operates at 1500MHz.

Power Consumption
With a rated board TDP of 50W, it requires at least a 350W PSU and relies entirely on the PCI Slot for Power, meaning no Extra Connectors are required.

Performance
This graphics card was designed and marketed towards the competitive MOBA gamers with laptops. A light weight, small form factor GPU solution that offers mobility. The Radeon RX 54X0 4GB Mobile can play most modern games at medium graphics selection on a 1080p screen res and expect around 45+FPS. Performance is exactly the same as the Radeon RX 540.

System Suggestions
Radeon RX 540 4GB is best suited for resolutions up to and including 1600x900. We recommend a Performance Processor and 8GB of RAM for Optimal Performance.
GeForce GTX 675M SLI is a solution of two GeForce GTX 675M put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 675M to know more about its chip.
As usual, SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, about 35% better than a single GeForce GTX 675M performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce GTX 675M.
Even the most demanding games will run at the highest settings.
