AMD Radeon RX 540X vs NVIDIA GeForce GTX 980 vs AMD Radeon RX 560 (Laptop)

AMD Radeon RX 540X

The AMD Radeon RX 540X is mobile mid-range graphics card for laptops based on the Polaris 12 chip (most likely). It is manufactured in an improved 14 nm FinFET process and technically similar to the older Radeon RX 540. The only difference so far is a 4% higher theoretical peak performance (1.25 versus 1.2 TFLOPS according to AMD). Compared to Nvidia graphics cards, the gaming performance should be between the GeForce GTX 950M and GTX 960M.

The similar named Radeon 540X (without RX) offers a smaller memory bus and therefore also a slightly reduced performance.

The features of the Radeon RX 540X are identical to the faster RX 460 and all other Polaris chips. See more details on the Polaris architecture here.

The power envelope of the faster Radeon Pro 460 is rated at 35 Watt according to the AMD blog post. Due to the slower specs, the Radeon RX 540 use slightly less.

NVIDIA GeForce GTX 980

The NVIDIA GeForce GTX 980 is a high-end desktop graphics card based on the second generation Maxwell architecture. The GM204 chip is manufactured in 28 nm at TSMC. Compared to the older GeForce GTX 780Ti, the 980 offers similar performance levels but at reduced average power consumption. The similarly named Nvidia Geforce GTX 980M for notebooks is based on the same chip, but uses less shader cores and slower clock speeds for reduced performance. Since end of 2015, the GTX 980 is also used in laptops (same chip with same clocks and branding).

The Geforce GTX 980 supports a range of unique features like CUDA, 3D Vision, PhysX, GeForce Experience, GameStream, GPU Boost 3.0, Adaptive Vertical-Sync / G-Sync, SLI, DSR, MFAA and Virtual Reality latency improvements.

AMD Radeon RX 560 (Laptop)

The AMD Radeon RX 560 for laptops (RX 560M) is a mid-range Polaris 11 / 21 gaming graphics card for laptops. It was first shown at CES 2017 in the Lenovo Legion Y520 as the "AMD RX 560M" with up to 4 GB GDDR5 VRAM. As the desktop RX 560 it can be based on the Polaris 21 and 11 chip (RX 560 and RX 460) with 986 or 1024 shaders. The performance should be similar to the desktop variants, with slightly reduced clock speeds.
