In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 540 4GB Mobile are noticeably better than the Nvidia GeForce GTX 770M.

The RX 540 has a 313 MHz higher core clock speed than the GeForce GTX 770M, but the GeForce GTX 770M has 48 more Texture Mapping Units than the RX 540. As a result, the GeForce GTX 770M exhibits a 28.9 GTexel/s better Texture Fill Rate than the RX 540. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 540 has a 313 MHz higher core clock speed than the GeForce GTX 770M, but the GeForce GTX 770M has 8 more Render Output Units than the RX 540. As a result, the GeForce GTX 770M exhibits a 1.5 GPixel/s better Pixel Fill Rate than the RX 540. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 540 was released over three years more recently than the GeForce GTX 770M, and so the RX 540 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce GTX 770M when running the latest games.

The RX 540 has 1024 MB more video memory than the GeForce GTX 770M, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GeForce GTX 770M has 96.2 GB/sec greater memory bandwidth than the RX 540, which means that the memory performance of the GeForce GTX 770M is massively better than the RX 540.

The Radeon RX 540 4GB Mobile has 512 Shader Processing Units and the GeForce GTX 770M has 960. However, the actual shader performance of the RX 540 is 624 and the actual shader performance of the GeForce GTX 770M is 779. The GeForce GTX 770M having 155 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 770M delivers a significantly smoother and more efficient experience when processing graphical data than the RX 540.

The RX 540 transistor size technology is 14 nm (nanometers) smaller than the GeForce GTX 770M. This means that the RX 540 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 770M.

The Radeon RX 540 4GB Mobile requires 50 Watts to run and the GeForce GTX 770M requires 75 Watts. We would recommend a PSU with at least 350 Watts for the RX 540. The GeForce GTX 770M requires 25 Watts more than the RX 540 to run. The difference is not significant enough for the GeForce GTX 770M to have a noticeably larger impact on your yearly electricity bills than the RX 540.
