Intel Arrow Lake “Core Ultra 200” CPUs To Debut With “Fast Throttle”, Implementing Effective Thermal Management

Intel's next-gen Arrow Lake CPUs are reportedly going to debut with the "Fast Throttle" thermal management technique, ensuring optimal performance under stress.

For those unaware, Fast Throttle or "Per-Core Thermal Throttle" is a method that Intel employed with its Raptor Lake Refresh processors.

Traditionally, when your CPUs get hot, the entire processor gets slowed down, which we call thermal throttling, as well as TJMax in the professional language (used to indicate the maximum thermal threshold of the chip). While this does keep the temperatures down, it drastically affects the performance and leads to performance penalties, even if only a few cores are overheating. As an alternative, Intel introduced Fast Throttle with its 14th Gen Raptor Lake Refresh, and it looks like the feature will see a proper debut with the upcoming Arrow Lake "Core Ultra 200" Desktop CPUs as well, according to the leaker Jaykihn.

Intel Per Core Thermal Throttle will officially debut with Arrow Lake.

Diving into Fast Throttle, the mechanism focuses on dynamically adjusting the clock speed of individual cores within the CPU when one specific core gets too hot. In this manner, only the cores with higher temperatures adjust their clock, while the others run in routine, which results in overall performance compared to traditional throttling. Intel utilizes a method called "Clock Modulation," which focuses on turning the clocks off and on at a duty cycle, effectively stalling the cores with higher temperatures.

So, with the debut of Fast Throttle in Intel's Arrow Lake "Core Ultra 200" Desktop CPUs, we will certainly see improved thermal management. Interestingly, Fast Throttle enables overclockers to manage thermals on a core level as well, and Team Blue might bring in additional features with Arrow Lake, maybe providing more customization options. You can see a detailed guide by Skatter-Bencher which shows how Fast Throttle fares against other thermal management techniques/

It looks like, on the "thermal" side of things, Intel is trying to execute interesting techniques with its Arrow Lake CPUs since the firm was previously rumored to be developing an additional loading mechanism called the "RL-ILM," designed for the LGA-1851 socket type. With Fast Throttle and RL-ILM, we might witness decent thermal improvements since Arrow Lake is coming in blazing fast.
