Intel Tiger Lake-U CPUs have a PL2 Value (Max Boost Power) of 64W

Recently, we shared a post explaining how Intel’s Tiger Lake CPUs primarily perform on par with the existing Renoir chips when set to 15W TDP mode. Today, we have some more info on the same front, thanks to a video by LTT. In the video, we get to see the power draw of the Core i7-1185G7 under heavy load, as well as the other stats such as temps and voltage.

Note the temps

As you can see, while the maximum package power of the CPU doesn’t exceed 35W, the maximum allowed PL1 (stock clock power) is 41W while the PL2 value is a rather significant 64W!

That’s the same as the H series parts that range from 35W to 45W at stock clocks. Now, you may argue that the CPU doesn’t actually reach that 64W figure but thanks to that ADT review, we have an answer to that as well:

Both the 15W and 28W variants of the Core i7-1185G7 cross the 50W and get to around 54W under boost clocks. That just 10W under that 64W PL2 limit. In contrast, the Ryzen 7 4800U doesn’t cross 38W. It’s also possible that the unit sent to ADT had a slightly lower PL2 value than the one sent to LTT due to their in-depth reviews, but 54W is still quite a bit for a device with a rated stock TDP of 15W.
