Benchmarking 18 Years Of Intel Laptop CPUs: Panther Lake As Much As 95x The Speed Of Penryn

For those curious how far Intel laptop CPU performance has evolved over the past nearly two decades, here are power and performance numbers when re-benchmarking all of the Intel-powered laptop CPUs I have on hand that are still operational from Penryn to Panther Lake. A ThinkPad from 2008 with the Core 2 Duo T9300 "Penryn" was still firing up and working with the latest upstream Intel open-source Linux driver support on Ubuntu 26.04 development. On a geo mean basis over the past 18 years from Penryn to Panther Lake, the performance was at 21.5x in over 150 benchmarks. At the most extreme was a 95x difference going from Intel's 45nm Penryn to the 18A Panther Lake.
