The smart phone market and the related chipset is seeing the same jump in performance that personal computers saw in their first decade.
Could Windows 95 run on a computer from 1985?
My 2009 era Core 2 Duo Dell E6500 - that I still own (https://www.notebookcheck.net/Review-Dell-Latitude-E6500-Not...) had 8 GB of RAM, gigabit Ethernet, a 1920x1200 display, 160GB hard drive, etc. Besides the processor, those are still decent specs for today and even the processor is good enough
The iPhone of 2009 was a 3GS - 320x480 display, 256MB of RAM,802.11G, with a single core 400Mhz processor and slow video graphics by today’s standards.
Compare that to the specs of even the low end $475 iPhone 7.
The Core 2 Duo was already a 64 bit processor. The iPhone didn’t ship with a 64 bit processor until four years later.
