Intel has consistently pushed processor technology boundaries, delivering some of the best CPUs seen. A recent test by Phoronix examined 15 mobile Intel processors spanning 18 years, from the 45nm Penryn architecture to the cutting-edge Panther Lake. The results are astonishing, with Panther Lake delivering up to 95 times higher performance than Penryn in specific workloads like OpenSSL and AI tasks.
The oldest chip tested, the 2008 Core 2 Duo T9300 in a Lenovo ThinkPad T61, highlights remarkable longevity. From dual-core being the standard then, modern mobile Intel CPUs now feature up to 16 cores, benefiting from a hybrid architecture combining performance and efficiency cores.
Phoronix ran 150 benchmarks on each processor under Ubuntu. The geometric mean of all results showed the Panther Lake-based Core Ultra X7 358H outperforming the Core 2 Duo T9300 by 21.5 times. In more modern comparisons, it was up to 9.7 times faster than a Sandy Bridge chip while consuming less power on average.
The performance gains are quantitative proof of Intel's architectural progress. Equally impressive is Linux's support for legacy hardware, allowing a 2008 processor to run modern benchmarks on a development version of Ubuntu.
