1. Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip and 16GB of RAM. Performance per watt refers to the ratio of peak CPU performance to average power consumed using select industry-standard benchmarks. Comparison made against high-performing CPUs for notebooks and desktops commercially available at the time of testing. Performance tests are conducted using specific computer systems and reflect the approximate performance of MacBook Pro.

2. Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip, as well as production 1.7GHz quad-core Intel Core i7-based 13-inch MacBook Pro systems, all configured with 16GB RAM and 2TB SSD. Open source project built with prerelease Xcode 12.2 with Apple Clang 12.0.0, Ninja 1.10.0.git and CMake 3.16.5. Performance tests are conducted using specific computer systems and reflect the approximate performance of MacBook Pro.

Performance tests are conducted using specific computer systems and reflect the approximate performance of MacBook Pro.

4. Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip, as well as production 1.7GHz quad-core Intel Core i7-based 13-inch MacBook Pro systems, all configured with 16GB RAM and 2TB SSD. Tested with prerelease Xcode 12.2 and Create ML 2.0, with an Action Classification model created in the app. Performance tests are conducted using specific computer systems and reflect the approximate performance of MacBook Pro.

5 Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip, 8GB of RAM and 512GB SSD. The Apple TV app movie playback test measures battery life by playing back HD 1080p content with display brightness set to 8 clicks from bottom. Battery life varies by use and configuration. See apple.com/ca/batteries for more information.

6. 1TB = 1 trillion bytes; actual formatted capacity less.

7. Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip, configured with 16GB RAM and 2TB SSD.
