Advantages of NVIDIA GeForce GTX 980 SLI Mobile

Much newer (22 September 2015 vs 5 January 2013)
Cheaper ($301.00 USD vs $5781.00 USD)
More pipelines (4096 vs 2496)
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 NVIDIA Tesla K20m

Wider memory bus (320 vs 256 bit)
Less power hungry (225 vs 330 watts)
