In context: Intel’s Thirteenth-generation Raptor Lake CPUs introduced many efficiency enhancements but in addition had a couple of points, together with operating sizzling. To assist fight the warmth issue, Intel baked in a brand new thermal throttling know-how referred to as Quick Throttle. Nevertheless, it was a quiet launch – barely even talked about within the flurry of Raptor Lake protection.
An X person who goes by “Jaykihn” claims that “Intel Per Core Thermal Throttle” formally debuts with Arrow Lake. Quick Throttle provides Intel’s CPUs some added thermal headroom by offering extra granular efficiency throttling when temperatures get too excessive. Somewhat than simply bluntly dialing again clock speeds throughout the entire processor, it will probably exactly goal the person CPU cores which might be getting too sizzling.
A per-core thermal throttling method is totally different from the everyday temperature safety strategies used earlier than. These principally have a look at the general chip temperature and take broader actions like capping frequencies, downclocking turbo increase habits, or adjusting voltages.
Intel Per Core Thermal Throttle will formally debut with Arrow Lake.
I’ve linked a third-party article written by @skatterbencher, showcasing this function’s efficiency throughout its restricted debut on Raptor Lake Refresh.https://t.co/MnYLeUAVZM

With Quick Throttle, Intel is utilizing a intelligent thought referred to as clock modulation. As an alternative of adjusting clock hastens or down, it briefly turns off the bodily CPU clock to explicit cores for tiny splits of time. The result’s way more nuanced thermal administration. If only one core or two is spiking in temperature, Quick Throttle can selectively dial them again with out disturbing the efficiency of the opposite cores, that are nonetheless operating cool.
Nevertheless, when Raptor Lake launched, Quick Throttle was locked down. Intel hadn’t uncovered any controls for customers to configure it manually. That modified with the late 2023 Raptor Lake refresh, lastly giving overclockers and PC lovers the keys to tinker with it. If Jaykihn’s tip is legitimate, Arrow Lake could provide handbook controls proper out of the gate.
For a lot of of as we speak’s overclocked gaming rigs and workstations, thermal constraints are one of many largest limiters on uncooked efficiency. So, having finer throttling levers like Quick Throttle to squeeze out further headroom could possibly be big.
Intel expects to launch its Fifteenth-generation Arrow Lake processors within the second half of 2024, possible between October and December. Nevertheless, some rumors recommend that laptops with the brand new CPU could not arrive till early 2025. Jaykihn not too long ago reported that motherboards sporting 800-series chipsets will accompany the brand new chips.
