Intel plans an entry-level Panther Lake chip with 4 Xe3 cores for handhelds

Intel's handheld lineup might be about to get a cheaper little sibling. According to leaker Jaykihn, who has a solid track record with Intel spec leaks, the company appears to be prepping a Panther Lake handheld chip with a "4+0+4+4" layout, which apparently means four P-cores, zero E-cores, four LPE cores, and four Xe3 graphics cores.

That's a noticeably smaller setup than the Arc G3 and Arc G3 Extreme chips Intel already ships in handhelds like the MSI Claw 8 EX AI+, which pair a 14-core design (2 P-cores, 8 E-cores, 4 LPE cores) with 10 or 12 Xe3 graphics cores depending on the SKU.

What's interesting is that this smaller 4+0+4+4 configuration has been seen before. It's already shipping in Panther Lake U laptop chips like the Core Ultra 7 355 and Core Ultra 5 325, currently found in machines like the Dell XPS 14 and XPS 16. So it looks like Intel, or possibly an OEM partner, is simply repurposing an existing laptop chip for a cheaper handheld tier rather than designing something new from scratch.

We don't have handheld-specific clock speeds yet, but based on how the Ultra 7 355 performs in laptops, we can get a rough idea of what to expect. According to Notebookcheck, in Cinebench R20, it's roughly twice as fast as the Steam Deck OLED's Zen 2 chip in single-core work and nearly three times as fast in multi-core.

Compared to AMD's Ryzen Z1 Extreme in the ROG Ally X, it's more of a mixed bag: about 10% faster in single-core but roughly 25% behind in multi-core. On the GPU side, Geekbench numbers put it around 19% behind the Ally X's Radeon 780M, though it comfortably beats the Steam Deck's integrated graphics by about 34%.

Of course, this isn't official yet, and Intel hasn't confirmed pricing, clocks, or even that this chip is destined for a handheld at all. As for price, Arc G3 and G3 Extreme handhelds like the Claw 8 EX AI+ and Predator Atlas 8 comfortably cross $1,000, and a smaller, cheaper Panther Lake chip could open the door to something closer to $800 or even less.

It probably won't touch the flagship Arc G3 Extreme chips powering this year's premium handhelds, but if it lands anywhere near what current Panther Lake U laptops deliver, it should still be a solid step up from budget options and a real alternative to AMD in a segment Valve and its partners have owned for years.
