HP Dev One With Ryzen 7 PRO 5850U Competes Well Against Intel's Core i7 1280P "Alder Lake P" On Linux

First up is a look at the integrated graphics performance for this set of Intel/AMD laptops under the Pop!_OS Linux distribution.

The graphics performance of Alder Lake P for the i7-1280P with 96 EUs was rather mixed. In some of the gaming benchmarks the Core i7 1280P successfully outperformed the Ryzen 7 PRO 5850U with its Radeon Vega graphics while in other instances the aging Vega graphics were still faster than this ADL-P laptop. At least though there were very nice gains on the Intel side in moving from prior generation Tiger Lake to Alder Lake P.

But even when the Alder Lake P graphics came ahead of the Ryzen 7 PRO 5850U Radeon graphics, the AMD Cezanne laptops were delivering better power efficiency than the i7-1280P with the SoC power monitoring via the PowerCap sysfs interface. But the HP Dev One after all is focused on "developers", so let's move on to more serious workloads.

While the Core i7 1280P has 20 threads to the Ryzen 7 PRO 5850U at 16 threads, the intel chip has only six performance cores that still leads to the Zen 3 5850U performing well against Intel's new laptop chips even though the 5850U launched back in March 2021.

With Alder Lake P there isn't AVX-512 support, unlike the prior generation Tiger Lake. So for workloads like simdjson that do have AVX-512 kernel support, this actually led to the new Intel processor performing much worse than the Tiger Lake Core i7 1185G7.

Even on a power efficiency basis, the Tiger Lake i7-1185G7 with AVX-512 came out ahead of the i7-1280P.
