Notes: MBP refers to the newest MacBook Pro. The R9 M370x is the upgraded GPU in the latest Macbook Pro 15". The Iris Pro is the standard GPU. We used the upgraded GPU in BlenchMark because the Iris Pro was incapable of running the tool. Heaven Benchmarks were run on an external display. Because of hardware limitations in Thunderbolt 2, performance increases are lower on the internal display (this is not an issue for Thunderbolt 3 computers).
