HP Dev One with Ryzen 7 PRO 5850U competes well against Intel's Core i7 1280P Alder Lake P on Linux

The Core i7 1280P is Intel's current top-of-the-line chip for the Alder Lake P series. The Core i7 1280P is a 20 thread processor made up of six performance cores (plus HT) and then eight power efficient cores. This 6 P + 8 E core laptop SoC has a maximum turbo frequency of 4.8GHz and a efficient-core max turbo frequency of 3.6GHz. The i7-1280P has a 28 Watt TDP base power and 64 Watt maximum turbo power rating and the chip has a 24MB cache. The HP Dev One as a reminder uses the year-old Ryzen 7 PRO 5850U Zen3-based mobile processor. The Ryzen 7 PRO 5850U has eight cores / sixteen threads but all Zen 3 cores and no "efficiency" cores against the 6 P + 8 E design of the i7-1280P. The 5850U has a maximum boost clock of 4.4GHz and base clock of 1.9GHz along with a 16MB cache. The default TDP on the Ryzen 7 PRO 5850U is 15 Watts. The Ryzen 7 PRO 5850U had an average SoC power consumption of 14.1 Watts and a peak of 30 Watts while the Core i7 1280P had a 29.5 Watt average and a maximum power draw of 76 Watts. The Core i7 1280P came out overall inline with the Ryzen 7 PRO 5850U performance. Even the Ryzen 7 PRO 5850U as launched last year can compete with today's flagship Alder Lake P processor on Linux. The Ryzen 7 PRO 5850U certainly was far better when it came to power efficiency as well with a much better performance-per-Watt.
