It never gets as hot, and it stays at 22W for 15 minutes instead of blowing through its STAPM limit in under 10m.Ryzen Controller allows you to tweak settings that will alter your laptops STAPM, or Skin Temperature Aware Power Management. My 2700U came with a 25W boost and 20W STAPM limit, I dramatically improved temperatures and medium-term performance by reducing Boost to 22W. I would reduce your boost TDP so that it doesn't cook the CPU and also takes longer to reach the STAPM limit. IMO, a 2500U runs optimally with about 22Watts and the restrictive 12W STAPM enforced by some designs is too strict. Look for a utility called Ryzen Controller that will let you adjust your STAPM limit, as well as your boost limit. To me it looks like your laptop's cooling isn't enough to handle the boost TDP and you are hitting 92C, resulting in thermal throttling. Mobile Ryzen will boost at a peak TDP until it approaches an STAPM limit, and it will power-throttle the whole CPU package down to the STAPM limit until you give it idle time to recover. 2500U can easily use >15W on 4C/8T loads if it's a synthetic load designed for stress testing at maximum power draw. You may be hitting the TDP limit configured by HP for that model. You'll want to look at socket power draw compared to boost TDP and STAPM limits.
