https://community.intel.com/t5/Software-Tuning-Performance/Wattage-and-performance/m-p/1706862#M8560 I’m seeking clarification regarding the expected power requirements and stability thresholds for 12th Gen Intel Core i5 laptop processors, specifically the H-series (e.g., i5-12450H / i5-12500H).<BR /><BR />I recently purchased a laptop using one of these CPUs, and I’ve been experiencing severe performance instability, including:<BR />• Crashing and freezing under moderate load<BR />• Lag and stuttering during multitasking or gaming<BR />• Inability to maintain stable internet or Discord calls<BR />• Frequent CPU throttling and sub-1.0 GHz clock speeds under load<BR /><BR />The manufacturer has configured the CPU to operate at a fixed 20W power limit (PL1/PL2), which they claim is sufficient for “normal use,” although “normal” is not defined and it was advertised for gaming.<BR />However, an independent technician has tested the device and confirmed that these issues are a direct result of power delivery limitations, not software or thermal concerns. When the CPU is allowed to use 35W or more, the instability vanishes or becomes bearable to play.<BR /><BR />Given Intel’s own specifications for these processors (which list Base Power around 35W and Turbo Power often exceeding 60W), I would appreciate clarification on the following:<BR />1. Is a fixed 20W PL1/PL2 setting sufficient for stable performance in gaming and multitasking scenarios on 12th Gen i5 H-series CPUs?<BR /><BR />2. Does operating such CPU at only 20W angainst Intel’s intended design envelope for normal usage?<BR /><BR />3. Could forcing this CPU to run at 20W cause performance below expected thresholds, or instability such as freezing, underclocking, or stuttering?<BR /><BR />4. Would this be consider a design deployment outside the processor’s recommended operating parameters?<BR /><BR />Thank you in advance for any insight. I’m trying to determine whether this is a power configuration issue or if the CPU itself may be faulty.
