OneXPlayer X1 leak with Intel Panther Lake Core Ultra 5 338H and Arc B370

OneXPlayer looks poised to be among the first manufacturers to ship a handheld gaming console built on Intel’s next‑generation Panther Lake mobile platform. A leak from the Geekbench database reveals a new OneXPlayer X1 variant with a Core Ultra 5 338H processor, effectively confirming the device is in the works.

According to the test sample, the Core Ultra 5 338H carries a 12‑core configuration with a 1.90 GHz base clock and boost up to 3.68 GHz. Earlier reports described the chip as a 4P+8E+4e layout, and for a portable console that core count looks particularly ambitious.

The graphics side stands out as well: the Core Ultra 5 338H integrates a new Arc B370 GPU based on the Xe3 architecture, with 10 Xe cores and frequencies up to 2.4 GHz. Early leak data puts this iGPU near the Radeon 880M in Vulkan performance, clearly outpacing the previous Xe2 generation from Lunar Lake.

The OneXPlayer X1 has long embraced a 3‑in‑1 concept: a tablet, a mini‑laptop, and a handheld console with a 10.95‑inch 2560×1600 display at 120 Hz and detachable controllers. Earlier models shipped with AMD Ryzen and Intel Core Ultra V chips; now the line appears to be shifting to Panther Lake.

In Geekbench, the device posted 2,428 points in single‑core and 13,265 in multi‑core tests, pointing to a solid jump in compute performance. If the numbers hold, the X1 would be among the first gaming handhelds on Intel’s new mobile platform. OneXPlayer has not issued official comments, but the scope of the leak suggests an announcement could arrive in the coming months.
