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

In total 80+ performance tests were carried out on this set of laptops for seeing how well the Intel Core i7 1280P "Alder Lake P" performs under Linux. All of the individual benchmark results can be found via this OpenBenchmarking.org result page.

Here is a look at the CPU power consumption over the entire span of all the benchmarks conducted. 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 i7-1280P showed a 15% higher average power consumption over the i7-1185G7 Tiger Lake and a 7% higher peak power consumption.

When taking the geometric mean of the 81 individual raw performance benchmark results, the Core i7 1280P came out overall inline with the Ryzen 7 PRO 5850U performance. But as shown by the diverse range of benchmarks it largely depends upon your workloads for how competitive Cezanne / Zen 3 mobile is with Alder Lake P. The Intel Core i7 1280P performed very well for browser workloads, Python scripting, and other areas while the Ryzen 7 PRO 5850U was strong for code compilation and many other creator workloads with its eight core / sixteen thread design.

So while it would have been even more enticing to find the HP Dev One with an AMD Ryzen 6000 "Rembrandt" APU with the refreshed Zen 3+ design, 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.

The Core i7 1280P came out around 30% faster than the prior generation Core i7 1185G7 "Tiger Lake" processor, which isn't surprising at all given the higher core/thread count. The Tiger Lake SoC still stood its ground well though for workloads with AVX-512 support.

With just having the Intel Core i7 1280P in my lab a short time so far, stay tuned for more Linux testing to come from this Alder Lake P laptop.
