Let's see how good GeForce GTX 950M and Iris Pro Graphics P580 are for gaming. Particular gaming benchmark results are measured in FPS.
Advantages of NVIDIA GeForce GTX 950M
29.6% faster in synthetic tests
More pipelines (640 vs 576)
Battery Boost (saves energy while gaming by lowering FPS to a still acceptable level. Can make a laptop working on battery twice as long, depending on the particular game)
ShadowPlay (allows recording and streaming video during gaming on NVIDIA GPUs)
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)
Advantages of Intel Iris Pro Graphics P580
Somewhat newer (1 September 2015 vs 13 March 2015)
Finer manufacturing process technology (14 vs 28 nm)
Less power hungry (15 vs 75 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)
