Testing was conducted on Ubuntu 26.04 across 150+ benchmarks on 15 different laptops. On a geometric mean basis, Panther Lake delivers 21.5x the performance of Penryn, with the most extreme individual benchmark showing a 95x speedup. The comparison also tracks CPU power consumption (via RAPL/PowerCap) from Sandy Bridge onward to evaluate performance-per-watt improvements across generations. ## Full article daily.dev links to this article rather than hosting it.
