What has actually surfaced
Notebookcheck reports that YouTuber Cary Golomb has shared hands-on photos of the Win Mini Ultra ahead of GPD's official announcement. The same report says Retro Game Corps indicates GPD is sending units to reviewers in large numbers. That suggests reviews could arrive soon, but nobody has given a launch date.
Notebookcheck says GPD has not published official specifications. Golomb did confirm two things:
- Display: The screen is an IPS panel with variable refresh rate (VRR) support.
- Chassis: His photos show a taller, wider and thicker body than earlier Win Mini models. That makes room for a larger display and a revised keyboard.
Leaked figures: treat as provisional
Notebookcheck cites a recent leak for an 8-inch display in a 182.5 x 133 x 30 mm body weighing 845 g. These are not GPD figures. The preview report also doesn't give a resolution or refresh-rate range.
An earlier Notebookcheck report, from October 28, covered a different leak. It pointed to a 1200p, 120 Hz IPS panel with Adaptive Sync, 32 GB of LPDDR5X, a 2280 M.2 SSD slot and two USB4 v2 ports. It also pointed to cooling for a 45 W TDP mode, 100 W USB-C PD charging and a 56 Wh battery. GPD confirmed none of this. In that report the company only confirmed the Intel Arc G3 Extreme chip, via a Weibo post.
The silicon: Arc G3 Extreme and Arc B390
The chip is the part with the firmest public documentation, because Intel has published its specs. Tom's Hardware's coverage of the Arc G3 launch lists the Arc G3 Extreme as 14 cores (2 P-cores, 8 E-cores and 4 LP E-cores), a 4.7 GHz max P-core turbo, 12 MB of L3 cache and a configurable TDP of 8–35 W. The chips are built on Panther Lake (Core Ultra Series 3) silicon. The Extreme pairs this with the Arc B390 iGPU. The B390 has 12 Xe3 cores, against 10 on the cheaper Arc B370. Wccftech's coverage of the launch adds that the B390 runs at up to 2.3 GHz and that the chip supports LPDDR5X-8533 memory.
One caveat matters for buyers. Intel's 35 W ceiling is a configurable range for the chip. It doesn't tell us what GPD will allow in each profile. A 45 W figure from a leak would exceed Intel's listed range, so I'd wait for GPD's confirmation before believing it.
How big is the performance jump?
The Win Mini line currently tops out at AMD's Ryzen AI 9 HX 370 with Radeon 890M graphics. Notebookcheck says its own benchmarks suggest the Intel chip should give the Win Mini Ultra more than 50% faster in-game performance than the Win Mini 2025. Golomb called the performance "awesome."
Before you lean on those numbers:
- The Notebookcheck figure is an expectation drawn from chip benchmarks. It is not a measurement of the Win Mini Ultra.
- The report doesn't name the games, settings or power limits behind it.
- Sustained performance, fan noise, surface temperatures and battery life in a small chassis are all unknown.
- Handheld results depend heavily on the power limit. A 50% lead at one wattage can shrink or grow at another.
Why Windows users should care
This is a full x86 Windows machine, not a console-style closed device. A Panther Lake handheld brings Intel's Xe3 graphics stack to the Windows handheld category, which AMD-based devices have largely dominated. The keyboard also stays, which matters for people who want a pocketable machine for light desktop work as well as gaming. Reported Arc G3 features include XeSS 3 upscaling and Intel precompiled shaders. Tom's Hardware's coverage of the launch lists both.
What's still unknown
- Official launch date, regional availability and pricing. Notebookcheck's October report said the device is expected to cost less than the HX 370 Win Mini 2025. That is an expectation, not a price.
- Final display resolution, refresh rate and brightness.
- Battery capacity, charging behavior and configurable power modes.
- Thermals and fan noise under sustained load.
Bottom line
The picture is clearer than a rumor but short of a spec sheet. The confirmed items are the Arc G3 Extreme chip (confirmed by GPD), a VRR-capable IPS screen and a bigger body with a revised keyboard (both from Golomb's hands-on). Everything else is leak or projection. With review units reportedly shipping, independent benchmarks and teardowns may arrive soon. Anyone considering one should wait for those and for official pricing.
