Samsung appears to be gearing up a major refresh of its premium laptops, with the Galaxy Book6 Pro poised to debut Intel’s next-generation Core Ultra Series 3, codenamed Panther Lake. A fresh Geekbench listing points to Samsung joining other OEMs in readying thinner, faster, and more efficient machines powered by Intel’s new mobile chips.
The leaked configuration shows the Galaxy Book6 Pro running the Intel Core Ultra 5 338H, a mainstream Panther Lake part that should offer a strong balance of CPU and integrated graphics performance for everyday productivity and creative workloads. According to the listing, the chip carries a 1.90 GHz base clock with an expected boost around 4.70 GHz, and it features Intel’s Arc B370 iGPU built on the Xe3 graphics architecture. The CPU topology includes 4 Performance cores, 4 Efficiency cores, and 4 Low-Power Efficiency cores, a hybrid design aimed at delivering speed when you need it and excellent battery life when you don’t.
Early AI benchmarks attached to the leak were run through the ONNX framework on the CPU, so they don’t tell the full story of what Panther Lake’s NPU and Xe3 iGPU can do for AI-accelerated tasks. Expect more meaningful generational comparisons once tests tap into the integrated graphics and neural processing unit, where much of Intel’s mobile AI uplift is expected to shine versus Arrow Lake and Lunar Lake systems.
The leak also suggests both the Galaxy Book6 Pro and the standard Galaxy Book6 will ship with Intel Core Ultra Series 3 options. As always with pre-release data, treat early numbers as provisional. Firmware, drivers, and power profiles can significantly influence results, especially this far ahead of retail availability.
What to expect from Intel’s Panther Lake mobile stack
– H-series performance chips target 45W TDP, with configurations commonly featuring 4 P-cores, 4–8 E-cores, and 4 LP-E cores, plus Xe3 graphics that can scale up to a dozen compute clusters on higher-end models.
– U-series efficiency chips target 15–28W TDP, prioritizing battery life while keeping the hybrid core layout and next-gen integrated graphics.
– The Core Ultra 5 338H, spotted in the Galaxy Book6 Pro, is listed with a 45W TDP and Arc B370 graphics. Preliminary lineups indicate higher-tier H-series parts, such as Core Ultra X9 and X7 variants, with larger iGPU configurations for creators and light gaming.
Timing is lining up for an incremental rollout. Intel is expected to begin releasing its first Panther Lake SKU this quarter, with more models to follow and a broader unveiling slated for January at CES 2026. If Samsung maintains its usual cadence, the Galaxy Book6 family should be among the first wave of premium Windows laptops to showcase these chips.
Bottom line: If the early indicators hold, the Samsung Galaxy Book6 Pro with Intel Core Ultra Series 3 looks set to deliver a meaningful step forward in performance per watt, upgraded Xe3 graphics, and improved on-device AI capabilities. Keep an eye on upcoming benchmarks that leverage the NPU and iGPU to get a clearer picture of real-world gains.
