Advantages of NVIDIA GeForce GTX 980 SLI Mobile

Wider memory bus (256 vs 128 bit)
More pipelines (4096 vs 2048)
CUDA (Compute Unified Device Architecture - an API for video card computing power usage in tasks different from 3D graphics processing. Can be used for physics simulation for instance)
PhysX (hardware acceleration of physical simulation engine named PhysX)
G-SYNC (removes screen tearing by telling the display when to renew the image. Only works with G-SYNC compatible displays)

Advantages of AMD Radeon RX 6500 XT

Much newer (28 October 2020 vs 22 September 2015)
Finer manufacturing process technology (7 vs 28 nm)
Less power hungry (125 vs 330 watts)
