A recent technical comparison highlights how the modern iPhone 17’s A19 processor matches the raw computational speed of the 1980s-era Cray 2 supercomputer in specific performance benchmarks.

Key points

• The Cray 2, released in the mid-1980s, achieved a peak performance of 1.9 GFLOPS using four specialized vector processors.
• Modern iPhone 17 devices utilize the A19 processor, which offers comparable or superior raw processing power for general-purpose computing tasks.
• The Cray 2 utilized vector processing architecture, providing a distinct advantage for rapid calculations on large, specific data sets.
• The Cray 2 operated on a modified version of UNIX System V, offering users significant freedom to modify software and hardware configurations.
• Apple’s iOS maintains a restrictive "walled garden" ecosystem, contrasting with the open-access nature of the Cray 2’s original operating environment.

This comparison illustrates the exponential growth of consumer hardware capabilities while highlighting the trade-off between raw processing power and software accessibility. It underscores how modern mobile devices have surpassed the performance of historical supercomputers, even as proprietary ecosystems limit user control compared to legacy systems.
