Intel joins the Confusing Name Challenge with AMD
Just today we learned that AMD is preparing two additional Ryzen AI MAX SKUs: 392 and 382 . It turns out these names are not the most confusing ones around. Apparently Intel has updated its preliminary specs for upcoming mainstream and premium laptops, and here’s what we know.
The first thing we learned today is that the max boost for Panther Lake is 5.1 GHz . Some leakers claimed it would be higher, but it seems Intel has decided to lower expectations. This figure may still depend on the power settings and on how well the laptop can be cooled for single-threaded boost, notes Jaykihn, who revealed the full list of Panther Lake SKUs today.
Now, when it comes to naming, things get complicated. We previously saw premium SKUs such as 3_8H in leaks. This list has now been reshuffled, and there are also 3_6H SKUs. The premium 16-core SKUs will include variants like Core Ultra X9 386H but also Core Ultra X7 368H . So if you avoid using the Ultra tiers, you end up comparing 386H with 368H, which is hard to understand.
4+8+4
388H 5.1
386H 4.9
368H 5.0
366H 4.8
358H 4.8
356H 4.74+4+4
338H 4.7
336H 4.64+0+4
365 4.8
355 4.7
335 4.6
325 4.52+0+4
332 4.4
322 4.4— Jaykihn (@jaykihn0) November 5, 2025
The flagship SKU has a 5.1 GHz boost, 4 P-Cores, 8 E-Cores and 4 LP-Cores. The X9 and X7 SKUs will also ship with Arc B390 integrated graphics featuring a full 12 Xe3 configuration. Additionally, there is one part with an Arc B370 10 Xe3 core variant: Core Ultra 5 338H. The remaining SKUs have either 4 Xe3 cores, aimed at systems with discrete graphics (gaming laptops), or 2 Xe3 cores, aimed at the low-end segment.
When asked, Jakkihn clarified that there are changes to the TDP metrics for Panther Lake. Apparently there are two TDP specs. The high-end models will ship with a 25W default TDP and an optional max TDP of 65W or 80W (chosen by the OEM). The 8-core and 6-core variants use a default TDP of 25W and a max TDP of 55W.
Intel is also said to introduce a new metric called “ Experience Based PL1” , which was not mentioned in the architecture preview at Tech Tour in September.
No, all 4+4+4 and 4+8+4 have both 65W & 80W configurations.
OEMs choose. (preliminary)
Because PTL is hard to cool for ST boost.Experience Based PL1 will also debut on PTL. More info in the future.

I find the “new” list of Core Ultra 300 variants somewhat troubling. I am not sure how variants like Core Ultra 7 365 will compare to HX 370 from AMD in terms of “marketing power”.
Looking for a new laptop will be quite a challenge, given we have very similar-sounding names: HX 370, 365, B390, B370, 386H, 365H, MAX 392 and so on. It is an absolute mess that neither AMD nor Intel has tried to fix, unfortunately.
