CPU-Z devs confirms SKU names of upcoming Panther Lake chips

Looks like rumors were indeed true.

When the Core Ultra 300 SKUs names were first shared more than a week ago, we kept our natural skepticism, given that only one source casually listed them without further details. However, that information partially matched what other sources have been saying. Now it appears that the list is confirmed by developers of CPU‑Z software, their updates are rarely incorrect.

HWMonitor and CPU‑Z are not frequently updated, and apart from very few (often obvious) mistakes in SKU names in their changelog, a software update normally suggests that devs are certain. If that’s the case, then the last update for HWMonitor  1.6 confirms the SKU lists for the Core Ultra 300 series, codenamed Panther Lake.

The changelog confirms there are three series: two H‑Series and one U‑Series. The main difference between the so‑called X‑series is that they feature 12 or 10 Xe cores, whereas the SKUs without X have 4 Xe cores.

Panther Lake Series (according to CPU‑Z):

• H‑Series:
  • Intel Core Ultra X9 388H, Core Ultra X7 368H and 358H, Core Ultra X5 338H (Panther Lake‑H).
  • Intel Core Ultra 9 375H, Core Ultra 7 355H and 345H, Core Ultra 5 325H (Panther Lake‑H).
• U‑Series:
  • Intel Core Ultra 7 360U, Core Ultra 5 350U and 340U, Core Ultra 3 320U (Panther Lake‑U).

Last week Intel shared full architecture details on Panther Lake, confirming it uses Cougar Performance Cores and Dark Motor Efficient cores. Aside from the CPU architectures, the most interesting part for us is the new graphics called Xe3 . Interestingly, it looks like Intel will stick to B‑Series naming for integrated graphics, while everyone expected them to be part of the C (as in Celestial) family. That’s for next‑gen Xe3p series as we explained in this article .

In other words, the upcoming Core Ultra 300 series will have new SKU names: X9, X7 and X5, as opposed to 9/7/5. Such SKUs will have “8” as a third letter; Intel might add others like “6” later. This change will only apply to ‘premium’ chips with more powerful GPUs, presumably successors to the Lunar Lake series.

The gaming variants will use standard naming without X, and SKU names ending in “5”. The low‑power U‑Series variants stick to the “3_0U” naming scheme, so not much of a change there. The full list of SKUs and their rumored specs are as follows:
