Intel’s Next-Gen Nova Lake-H Mobile CPUs Leak: Ultra X7, Ultra 5, and X9 Models
Intel’s Next-Gen Mobile CPUs Leak: Ultra X7, Ultra 5, and X9 Models
A new leak has surfaced detailing Intel’s upcoming high‑performance mobile processors under the Core Ultra brand — including Ultra X7 368H, Ultra X7 358H, Ultra 5 338H, and X9 388H. With P‑core clocks reportedly reaching 5.0–5.1 GHz and integrated GPU speeds up to 2.5 GHz, these chips could represent Intel’s biggest mobile performance leap in years, targeting gamers, creators, and power users alike.
The Leaked Lineup
| Model | Max P‑core Clock | Max iGPU Clock | Notes |
|---|---|---|---|
| Ultra X7 368H | Up to 5.0 GHz | Up to 2.5 GHz | High‑end mobile SKU with strong iGPU performance |
| Ultra X7 358H | Not specified | Not specified | Slightly lower‑tier X7 variant |
| Ultra 5 338H | Not specified | Not specified | Mid‑range performance laptop SKU |
| X9 388H | Up to 5.1 GHz | Not specified | Flagship mobile SKU; highest reported P‑core clock |
Why This Likely Belongs to Nova Lake‑H
Although some early chatter linked these parts to Panther Lake, the specifications and branding align more closely with Intel’s high‑TDP Nova Lake‑H roadmap for 2026:
- Performance envelope: 5.0–5.1 GHz P‑core clocks and high‑frequency iGPU are consistent with Nova Lake‑H targets, not Panther Lake’s efficiency‑first design.
- Market positioning: “H”‑class chips power gaming laptops and mobile workstations, whereas Panther Lake is expected to focus on thin‑and‑light systems.
- Branding: Ultra 5 / Ultra 7 / Ultra 9 tiers with “H” suffix match Intel’s current high‑performance mobile naming scheme.
Architecture Expectations (Unconfirmed)
- CPU cores: Next‑gen P‑cores and E‑cores with improved efficiency and scheduling.
- Graphics: Xe3 “Celestial” iGPU architecture with higher clocks for stronger integrated performance.
- Platform: Advanced process node (rumored 2 nm for compute tile), modern I/O, AI acceleration, and upgraded media engines.
Speculative Performance Tiers
These configurations are informed estimates based on typical H‑series scaling from desktop parts. Actual specs may differ at launch.
| Model | Likely Core Focus | Target Segment | Notes |
|---|---|---|---|
| X9 388H | High P‑core clocks, ample E‑core capacity | Flagship gaming/creator laptops | Top bin; optimized for peak single‑thread and heavy multitasking |
| Ultra X7 368H | Balanced P‑core clocks with strong iGPU | High‑end creator/gaming laptops | Suited to dGPU‑optional designs and media workloads |
| Ultra X7 358H | Slightly reduced P‑core emphasis for thermals | Upper‑mid performance laptops | Targets efficient performance with sustained clocks |
| Ultra 5 338H | Moderate P‑core clocks, balanced E‑cores | Mainstream productivity/gaming | Focus on value; strong everyday performance |
Why It Matters
If accurate, this leak suggests Intel is preparing one of its most significant mobile CPU overhauls in years. Higher single‑thread ceilings, stronger integrated graphics
