1. Testing conducted by Apple in February 2020 using pre-production 1.2GHz quad-core Intel Core i7–based MacBook Air systems with Intel Iris Plus Graphics, 16GB of RAM and 2TB SSD, as well as shipping 1.6GHz dual-core Intel Core i5–based MacBook Air systems with Intel UHD Graphics 617, 16GB of RAM and 1TB SSD. Simulation of dynamical systems tested with MATLAB and Simulink R2019b Update 4 and  Parallel Computing Toolbox using a vehicle dynamics model. Performance tests are conducted using specific computer systems and reflect the approximate performance of MacBook Air.
2. Compared with non-Retina MacBook Air.
3. Testing conducted by Apple in February 2020 using pre-production 1.2GHz quad-core Intel Core i7–based MacBook Air systems with Intel Iris Plus Graphics, 16GB of RAM and 2TB SSD, as well as shipping 1.6GHz dual-core Intel Core i5–based MacBook Air systems with Intel UHD Graphics 617, 16GB of RAM and 1TB SSD. 3D title render speed tested with Final Cut Pro 10.4.8 using a 10-second project with Apple ProRes 422 video at 3840x2160 resolution and 30 frames per second. Performance tests are conducted using specific computer systems and reflect the approximate performance of MacBook Air.
