Blogger Jaykihn, who allegedly has access to samples of future processors and company documentation, reported that Intel has increased the maximum temperature (TJMax) for its future processors codenamed Arrow Lake and Panther Lake to 105°C.
Tjunction max is the highest temperature a processor can reach before its internal thermal control kicks in to reduce power and limit temperatures, potentially resulting in a loss of performance. Intel processors typically have a maximum temperature (TJMax) of around 100°C, which is typical for Alder Lake and Raptor Lake processors, and will likely be the same for the next-generation Lunar Lake processors. However, the TJMax of Intel Core Ultra processors (codenamed Meteor Lake) is set at 105°C or 110°C, depending on the version, and the upcoming Arrow Lake and Panther Lake processors are likely to have the same maximum temperature.
Developers should design systems so that the processor does not drop much below this threshold under heavy loads in order to maximize performance, so increasing TJMax is a good thing. However, if a laptop processor is running at 100°C to 105°C for a long time, the laptops will get hot. Apart from that, increasing TJMax may indicate that Intel has confidence in its silicon. Specifically, that it can withstand 105°C without degrading, which is also a good sign.
