Intel Arrow Lake / Panther Lake processor 'temperature wall' exposed to 105 degrees Celsius

News from this website on July 17th. Source @Jaykihn posted a tweet on the X platform yesterday (July 16th), revealing that the "temperature wall" temperature (TJmax) of Intel's Arrow Lake and Panther Lake processors is 105 degrees Celsius. 5 degrees Celsius higher than Raptor Lake processors.

Previous news said that Lunar Lake CPU will retain the 100 degrees Celsius TJMax design.

Note from this site: TJmax is the maximum temperature that the CPU can withstand. However, the TJMAX of each CPU will be different due to VID (physical constitution), so this "temperature wall" temperature is only used as a reference. In actual scenarios, it still depends on the specific CPU. constitution.

As you can see from the group table, VccCore (CPU voltage) has increased from 1.72V to 1.77V, while the GPU voltage has increased from 1.50V to 1.52V.

The rated current has also increased slightly, with the highest unlocked SKU increasing by 13-21%, the 65W SKU increasing by 5-18%, and the 35W SKU increasing by 49-79%.
