Intel Arrow Lake CPUs Get Increased Temperature “TJMax” & Power Ratings Versus Raptor Lake, Up To 105C

wccftech.com:

Intel's Arrow Lake & Panther Lake CPUs will feature a higher temperature limit of 105C compared to 100C on Raptor Lake CPUs.

Intel Sets Higher Temperature "TJMax" & Power "Electrical DC" Specifications For Arrow Lake CPUs

Intel's Arrow Lake CPUs will be coming to a range of platforms including high-performance Desktop "S", Enthusiast Laptops "HX", High-end Laptops "H", and low-power "U" designs. These chips will be configured with different core counts and iGPU configurations but it looks like the entire lineup will have one thing in common and those are increased temperature limits or "TJMax".

TJMax is a temperature limit that is the officially rated safe limit after which the CPU will lower its clock speed to preserve the integrity and prevent silicon from degrading or damaging itself over a prolonged use. According to @Jaykihn, Intel's Arrow Lake and Panther Lake CPUs will feature increased temperature limits of up to 105C which is 5C higher than Raptor Lake CPUs (100C). It is stated that Lunar Lake CPUs will retain the 100C TJMax design.

Some would say that the increased temperatures will prevent silicon degradation and prevent the CPU from running into the same issues that are currently affecting the 14th Gen & 13th Gen lineup but those issues happen despite the CPUs hitting their TJMax limit. Furthermore, the increased limit can be due to the higher density that the TSMC N3B process node has to offer. For comparison, the AMD Ryzen 9000 CPUs based on the N4P node have a maximum operating temperature of 95C so the blue team has a 10C higher rating which is a lot.

• Panther Lake TJMax - 105C
• Arrow Lake TJMax - 105C
• Lunar Lake TJMax - 100C
• Meteor Lake TJMax -100C
• Raptor Lake TJMax - 100C

Now temperature limits don't mean anything unless we know what the actual temperatures of these chips are. It's just a safe limit & while more recent CPUs
