AMD Radeon RX 580 (Laptop) vs NVIDIA GeForce GTX 980 Ti vs AMD Radeon RX 560 (Laptop)

AMD Radeon RX 580 (Laptop)

The AMD Radeon RX 580 is a high-end graphics card for laptops. It is based on the Polaris 20 chip. Compared to the Polaris 10 in the similar RX 480, the Polaris 20 is manufacted in an improved 14nm process (LPP+) for higher clock speeds and some power efficiency improvements in idle. The performance in laptops depends on the used clock speeds and should be similar to the desktop RX 470 (see for gaming benchmarks) or even RX 480.

NVIDIA GeForce GTX 980 Ti

The Nvidia GeForce GTX 980 Ti is a High-End desktop graphics card based on the Maxwell architecture. It uses the big GM200 chip with 2,816 CUDA cores (versus 2048 of the GTX 980) and is manufactured in 28 nm. Together with the NVidia Titan X (that uses the same chip with more graphics memory), the 980Ti was the fastest single chip graphics card for desktops in 2015. In 2016 the new Pascal based GeForce GTX 1070 and 1080 however were faster while using less energy thanks to the new architecture and the 16 nm process.

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.
