Intel is said to raise the TJMax to 105 degrees Celsius for the upcoming Arrow Lake and Panther Lake chips. It wants to achieve higher processor performance, according to the leaks.
Intel has reportedly raised the maximum thermal junction temperature (TJMax) for its upcoming Arrow Lake and Panther Lake processors to 105 degrees Celsius, according to leakster Jaykihn, who is said to have access to internal documents. The Alder Lake and Raptor Lake processors have TJMax set to 100°C, as do the new generation Lunar Lake processors. Intel Core Ultra processors (Meteor Lake) already have a TJMax of 105 or 110 °C depending on the version, which will probably be the case with Arrow Lake and Panther Lake as well.
The maximum temperature of the thermal junction (TJMax) is an important parameter that indicates the highest possible temperature of the processor before the protection mechanisms are activated. These mechanisms will reduce consumption and limit processor performance to prevent overheating.
Although higher TJMax means higher performance, laptops could get uncomfortably hot at around 100-105°C. The increase in TJMax indicates that Intel believes its new processors can handle higher temperatures without long-term degradation.
Jaykihn also released the specifications of the Panther Lake-H and Panther Lake-U processors. Panther Lake-U will have up to four high-performance cores, four low-power cores and four Xe graphics clusters with PBP 15W. The more powerful version will have up to eight powerful cores, four low-power cores and 12 Xe graphics clusters, with a maximum consumption of 25W.
