Intel has officially launched its first wave of "Panther Lake" mobile processors; as Core Ultra Series 3 products for deployment in laptops, notebooks, and mini PCs. A good chunk of the North American giant's CES 2026 presence was dedicated to their first AI PC platform built on the 18A process. A main talking point was the very best of "Panther Lake-H" integrated graphics solutions: Arc B390 . Utilizing "Xe3" architecture, this 12-core iGPU will compete with older RDNA 3.5-based AMD equivalents for the foreseeable future. Looking further along Intel's Arc roadmap, the more mysterious "Xe3P" technology is expected to debut within "Nova Lake" processors. Almost a year ago, Raichu linked "Xe3P" to next-gen Arc "Celestial" dGPUs.

Throughout 2025, leaks showed this architecture popping up in upcoming " Nova Lake " desktop and mobile processors, as well as " Crescent Island " data center accelerators. Last week, Raichu weighed in with another "Xe3P" prediction—proposing a 20-25% performance uplift over vanilla "Xe3." Additionally, they reckon that Intel's next-gen 12-core integrated graphics solution—presumably present in top "Nova Lake" APUs—could take things further, performance-wise. Raichu did not make a distinction between desktop and mobile parts; instead identifying "Nova Lake" as an overall processor family in a brief social media post. Interestingly, a July 2025 "Nova Lake-S" tape out-related leak suggested an unusual hybrid setup—with next-gen desktop processors supposedly utilizing Xe4 "Druid" architecture for "media and display duties."
