The CPU isn't increasing performance and is running at low frequency for unclear reasons.
I'm using an Intel Core i5-8250U with a base frequency of 1.60GHz and turbo up to 3.4GHz. The issue is that during 3D rendering, the CPU only reaches 83% of its capacity and doesn't meet expectations. The displayed frequency drops to 1.49GHz, then returns to 3.4GHz only when the CPU isn't under load. I've set my power plan to Windows Ultimate Performance, but the problem persists. Please help identify the cause.
It's acting like it's slowing down. Not sure if this is typical for your laptop, but you should look at the CPU temperatures. Checking tools like Core Temp can help. Make sure it doesn<|pad|>, it should stay under about 100°C. Also, keep an eye on maximum power usage!
Set up the Intel Power module and keep an eye on your temperatures. My 8250U tends to heat up a lot when under stress.
it's either thermal or power constraints (i think power is the issue since usage stays steady). The task manager checks CPU based on base frequency, so your base is 1.8, while your CPU maxes out at 1.5. That’s why you see "83%" usage—actually, it’s around 0.83 for the thermal limit. Your CPU speed will vary, but since your load stays consistent, it’s likely a power restriction.
I check the central temperatures and all cores show about 60°C. If power limits are an issue, I need to figure out how to address it. It’s worth noting that I used the Intel XTU app, but I only adjusted its power usage settings. Later I removed the app because I thought it might have caused the problem.
It seems the text is restricted by your laptop's maker. It doesn't make sense to continue without clarification.
wew that sucks, though it makes sense. seems like op has plenty of thermal headroom to work with, theres no way to unlock the usual boost clocks as a "permanently" allowed boost frequency? i forget the terminology
