Advantages of NVIDIA GeForce 940MX

Somewhat newer (28 June 2016 vs 1 September 2015)
More pipelines (512 vs 384)
GPU Boost 2.0 (increases NVIDIA GPU voltage and frequency when there's a temperature headroom. Similar to AMD PowerTune)
Optimus (lowers energy usage by automatically switching between integrated and discrete NVIDIA GPU. Similar to AMD Enduro)
PhysX (hardware acceleration of physical simulation engine named PhysX)
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)
GeForce Experience (software suite built to manage NVIDIA GPU parameters, and to record and stream game video)
GameWorks
Optimus Support
NVIDIAGameWorksSupport

Advantages of Intel Iris Graphics 540

42.8% faster in synthetic tests
Finer manufacturing process technology (14 vs 28 nm)
Less power hungry (15 vs 23 watts)
Quick Sync (hardware acceleration of video encoding and decoding for Intel CPUs. Speeds up video encoding by times, but at the cost of somewhat lower quality)
