A new entry in the FurMark database sheds more light on an early sample of a portable gaming device built on Intel’s Panther Lake. The specifications suggest hardware closely related to the upcoming OneXPlayer X1, even though the report does not mention a specific name.
The tested chip, an Intel Core Ultra 5 338H from the lower tier of Panther Lake, uses integrated Intel Arc B370 graphics with 10 Xe3 compute units and clock speeds ranging from 400 MHz to 2.3 GHz. An engineering driver, version 32.0.101.8188, is also listed, underscoring how early this unit is.
The layout and the stated native display resolution of 2560×1440 line up with earlier OneXPlayer X1 details, which indirectly ties these tests to that device. A new and telling metric appears here as well: a 36 W TDP, almost identical to the MSI Claw 8 AI Plus. For a compact handheld, that target suggests an effort to squeeze the most from the cooling system while keeping the device portable, hinting at ambitions beyond casual play if thermals cooperate.
In FurMark, the system scored 2383 points at 39 FPS, roughly in the ballpark of a GeForce GTX 1060. Given that FurMark is geared toward stress testing rather than real-world gaming, this looks like a push for stable, sustained performance rather than chasing the highest possible frame rates at this stage.
