iPhone
The iPhone 15 Pro's A17 Pro chip contains 19 billion transistors, executing instructions at speeds measured in teraflops. The neural engine alone performs 35 trillion operations per second, a figure so staggering that it would have seemed like science fiction mere decades ago. Data transfers occur at 5G speeds exceeding 1 Gbps, information coursing through invisible waves at velocities approaching the theoretical limits of wireless communication.
Yet this speed remains fundamentally abstract. One cannot witness an iPhone running; one merely observes the results of its labour. The device sits motionless whilst performing computational miracles invisible to the naked eye.
Sonic
Sonic's canonical running speed has been documented at 767 miles per hour - precisely the speed of sound, hence his name. This represents Mach 1, the velocity at which air molecules cannot move aside quickly enough, creating a sonic boom. When equipped with power-ups, official SEGA documentation confirms speeds approaching Mach 5, or roughly 3,800 miles per hour.
Unlike computational speed, Sonic's velocity is viscerally observable. Players have witnessed this blue blur circumnavigating loops, outrunning missiles, and leaving afterimages across Green Hill Zone for over three decades. His speed is not merely functional; it is identity itself.
