A fresh leak claims Intel's upcoming Panther Lake family will launch with a dozen SKUs spanning Core Ultra X, regular Core Ultra, and U-series chips. The rumor highlights varied iGPU configurations, new naming quirks and at least one surprising low-end X variant.
Inside the leak: what changed from earlier rumors
Earlier chatter hinted that only the Core Ultra X models would carry the highest iGPU counts. The latest screenshot circulating online largely confirms that idea — while also introducing an unexpected Core Ultra X5 model. The leak shifts the naming style too: instead of suffixing an "X", some entries place the "X" before the model (for example, Core Ultra 7 X368H vs Core Ultra X7 368H).
That naming ambiguity matters for cataloging and marketing, but the more useful takeaway is the hardware split. The leak outlines three tiers in the initial Panther Lake batch: top-tier Core Ultra X 3X8H parts with beefy iGPUs, mid-tier Core Ultra 3X5H chips with much smaller iGPUs, and low-power PTL-U models aimed at battery-efficient laptops.
Why the iGPU numbers matter
Intel’s Xe3 iGPU core count determines integrated graphics performance and affects thin-and-light gaming, content creation, and display-output capabilities. According to the leak, three flagship X models will sport 12 Xe3 cores, while a surprising X5 entry is limited to 10 Xe3 cores — suggesting Intel is willing to mix performance tiers inside the X family.

- Core Ultra 3 320U — P:2, E:0, LP-E:4, Xe3 iGPU: 4
What this means for laptops and buyers
If true, Intel’s segmentation is straightforward: X-designated parts aim for noticeably better integrated graphics, standard 3X5H chips focus on balanced CPU performance with modest iGPUs, and the U-series targets long battery life with conservative graphics. In practice, that means thin-and-light laptops could ship with four-Xe3-core iGPUs, while premium creator laptops will be able to advertise 10–12 Xe3 cores.
One caveat: leaked screenshots and early lists help paint a picture, but they’re not final. Naming conventions, SKU counts and exact core configurations may still shift before Intel’s official reveal. Treat these specs as a helpful roadmap — not an invoice.
Expect more details — and likely corrections — as additional leaks surface and Intel moves toward a formal announcement.
