Poor performance metrics for i7-8700 paired with NH-D15 processor
The system indicates power throttling due to a limit on maximum performance. To achieve optimal CPU speed, raise both PL1 and PL2 turbo settings in the BIOS. The standard limits will restrict performance and slow down the processor. Tools like ThrottleStop or Intel XTU can help adjust these limits within Windows. HWiNFO displays PL1 at the default 65W, which is insufficient for an 8th Gen CPU to operate at full capacity.
Absolutely confirmed, the numbers show a significant improvement—from about 80W to 125W and better performance overall. Thanks for sharing!
The brief PL2 power cap was established at 81.3W, which aligns with a peak usage of around 80W. Intel previously advised matching PL1 to its rated TDP—just 65W for an i7-8700. They also suggested PL2 should be about 25% higher than PL1. PL2 equals PL1 multiplied by 1.25, resulting in roughly 81.25W. These guidelines are not ideal. Both figures restrict performance noticeably. In extended tests using default settings, the CPU will automatically lower its clock speed to stay under 65W, sacrificing speed compared to the chip’s true potential. More users should consult HWiNFO data when experiencing throttling issues. Most enthusiast builds include a BIOS setting to push power limits to the maximum, 4095W—essentially unlimited. After enabling that, further throttling should cease. If the BIOS lacks such options, tools like ThrottleStop can help access turbo capabilities.
