Arrow Lake and Panther Lake, two new series of next-generation processors that are currently in development at Intel, may run even hotter than their predecessors, according to new rumors that claim these CPUs will feature a Tjunction max temperature of 105°C. This is 5°C higher than Intel’s current lineup, including Raptor Lake, whose CPUs list a Tjunction temp of 100°C among their specification sheets.
Tjunction max values in recent generations include:
- Panther Lake: 105°C
- Arrow Lake: 105°C
- Lunar Lake: 100°C
- Meteor Lake: 100°C
- Raptor Lake: 100°C
An explainer from Intel:
- “Tjunction max is the maximum thermal junction temperature that a processor will allow prior to using internal thermal control mechanisms to reduce power and limit temperature.”
- “Activation of the processor’s thermal control system may cause performance loss as the processor typically reduces frequency and power to prevent overheating.”
- “The maximum junction temperature limit varies per product and usually is between 100°C-110°C.”
- “The goal for a system builder or a do-it-yourself (DIY) end user is to design a platform configuration that keeps the processor under the Tjunction max threshold during heavy workloads to maximize performance of the system.”

Intel on Lunar Lake, its Series 2 Core Ultra mobile processors:
New Performance-cores (P-cores) and Efficient-cores (E-cores) deliver amazing performance at up to 40% lower system-on-chip power compared to the previous generation. A new neural processing unit is up to 4x faster, enabling corresponding improvements in generative AI, versus the previous generation. And new Xe2 graphics processing unit cores improve gaming and graphics performance by 1.5x over the previous generation.
