Intel's Panther Lake has finally shown up in a shipping mini PC, and Wendell at Level1Techs put one of the first through its paces: the MSI Cubi NUC AI+ 3MG, running the new Core Ultra 9 386H. We watched the full review so you don't have to — here's the buyer's-eye summary, plus what owners of Panther Lake hardware are actually saying on Reddit.
Full review: "Finally! Panther Lake! A Quick Look at the Cubi NUC AI+ 3MG" — Level1Techs (Wendell)
What the review covers
The MSI Cubi NUC AI+ 3MG is a genuinely tiny box built around the Core Ultra 9 386H — 16 cores (4 performance + 8 efficiency + 4 low-power) — with 32 GB of upgradeable DDR5, two Thunderbolt 4 ports, dual HDMI, and dual 2.5 GbE. Wendell highlights the business-friendly touches: a locking power connector, Kensington lock, an included remote power button, HDMI-CEC wake, and a VESA mount bracket to build a tidy upgradeable "all-in-one."
How it performs
The headline is a real generational jump: over 2,000 single-core and ~17,000 multi-core in Cinebench, and a class-leading 82 GB/s memory bandwidth that beats the older NUC platforms in the comparison. It's not a gaming box — but it surprised even Wendell, managing 62 FPS average in Shadow of the Tomb Raider at 1080p low. Thunderbolt 4 (not 5) means an eGPU is possible, though he'd cap it around a 5070-class card. The standout for this audience: Intel has gone "all in" on Linux support for Panther Lake, with Ubuntu LTS well supported out of the box.
What viewers are saying
The comments under the review are a useful temperature check. The platform enthusiasm is real:
"I'd love to see Panther Lake in a mini-ITX form factor so I can add a 100GbE NIC for a proxmox cluster." — @KenTechAdventures
So is the skepticism — and it's the kind worth heeding. Several viewers flagged that this specific 386H chip has the weakest iGPU of the Panther Lake range (@jenesuispasbavard noted it carries 4 Xe cores versus 12 on higher SKUs), and the perennial mini-PC gripe showed up too: "I see an external DC supply and immediately don't want it… please, have the power supply built in" (@lukeskywalker8107). One AMD loyalist was blunt — "quite expensive for what it is, I'll stick with AMD" (@nebadon2025).
What Panther Lake owners on Reddit are saying
Beyond this one box, Panther Lake silicon is landing well with early adopters. In r/pcmasterrace, u/Cicada-Tang's "Panther Lake CPU is pretty goated" post showed Borderlands 4 holding ~70 FPS on a Panther Lake handheld's integrated graphics:
"It's incredible to be able to carry that much power into a Starbucks… preferable to a traditional gaming laptop in almost every way." — u/FlanTamarind
But note that thread used a higher-iGPU Panther Lake chip than the 386H in this NUC — and the price skeptics are loud for a reason, with one commenter calling the gaming-handheld version "nearly a £2,000 tablet." On efficiency, r/laptops owners give Intel the nod over AMD's Strix Halo for battery life, while conceding Apple's M5 still leads. The honest read: Panther Lake is a legitimately strong, Linux-friendly platform — just buy the iGPU tier that matches your workload.
The bottom line
If you want a tiny, quiet, fleet-friendly Intel mini PC with modern I/O and excellent Linux support, the MSI Cubi NUC AI+ (Panther Lake) is a compelling 2026 upgrade — especially over a mini PC that's three-plus years old. Just go in clear-eyed: the 386H is the CPU-focused SKU, not the gaming one, and you're paying an early-adopter premium. Shoppers who want more graphics muscle should wait for, or seek out, the higher-Xe-core Panther Lake models.
