Key Takeaways
1. New gaming handhelds are being developed using Intel’s Panther Lake processors, with the Arc B380 as the intended integrated GPU (iGPU).
2. One-Netbook is working on the OneXPlayer X1, which will use the Core Ultra 5 338H processor and the Arc B370 iGPU.
3. The Arc B370 iGPU is rumored to feature 10 Xe3 cores and a boost clock of 2.4 GHz, with a configuration of 4 Performance and 8 Efficient clusters.
4. Early Geekbench tests show that the Panther Lake-based OneXPlayer X1 hasn’t yet outperformed previous models in single-core or multi-core benchmarks.
5. The OneXPlayer X1 is expected to launch around CES 2026, with specifications like a TDP of 65-80 W and an option for 32 GB of RAM.
Almost a month ago, there were rumors about new gaming handhelds being developed with Intel’s Panther Lake processors. To summarize, VideoCardz shared that the Arc B380, featuring 12 Xe3 cores, was the intended integrated GPU (iGPU). Earlier leaks suggested that the possible processors could be the Core Ultra X7 356H or the Core Ultra X7 358H, but VideoCardz thought that this might be a different processor specifically for handheld devices.
New Developments in Panther Lake Handhelds
Recent findings on Geekbench indicate that not all Panther Lake handhelds are following the earlier speculation. It looks like One-Netbook is in the process of creating its next OneXPlayer X1, which will use the regular Core Ultra 5 338H along with an Arc B370 iGPU. This iGPU is said to have 12 cores split into 4 Performance and 8 Efficient clusters, while the Arc B370 is rumored to have 10 Xe3 cores and a boost clock of 2.4 GHz.
Previous Models and Performance Expectations
For context, One-Netbook has previously launched OneXPlayer X1 series handhelds equipped with Intel’s Lunar Lake and Meteor Lake processors, in addition to AMD’s Hawk Point and Strix Point models (currently priced at $1,399 on Amazon). Up to now, the new Panther Lake-based OneXPlayer X1 hasn’t surpassed any of its earlier versions in Geekbench 6’s single-core or multi-core tests. Nevertheless, we are skeptical that this reflects the final performance, and it is unclear what wattage was used during these tests.
Key Specifications and Future Release
Putting the scores aside, the Core Ultra 5 338H is expected to have a thermal design power (TDP) of 65-80 W and can boost up to 4.7 GHz. Additionally, Geekbench notes that the upcoming OneXPlayer X1 will include 32 GB of RAM as a potential memory option. It’s likely that the first Panther Lake gaming handhelds will be officially revealed next month, during or just after CES 2026, which takes place from January 6 to January 9 in Las Vegas. Sadly, other specifics about the next OneXPlayer X1 are still not available at this time.
