Samsung's upcoming Galaxy Book6 Pro featuring the Intel Core Ultra Series 3 "Panther Lake" CPU has leaked out.
Samsung Preps Next-Gen Galaxy Book6 Pro Laptops With Intel's Core Ultra Series 3 "Panther Lake" CPUs
Laptop OEMs are now preparing their next-gen offerings based on Intel's upcoming Core Ultra Series 3 "Panther Lake" CPUs. These next-gen laptops will offer faster performance, advanced features, & higher efficiency. We will be looking at a range of new designs from laptop vendors, and Samsung is one of them, which is preparing its new Galaxy Book6 series.
The Samsung Galaxy Book6 Pro laptop has leaked on Geekbench, and confirms that it will feature Intel's Core Ultra Series 3 "Panther Lake" CPUs. Currently, just one configuration has been spotted, which packs the Intel Core Ultra 5 338H CPU. This is a mainstream design with decent compute and graphics.
In terms of specifications, the Intel Core Ultra 5 338H "Panther Lake" CPU is listed with a 1.90 GHz base clock, while the boost clock is expected to be around 4.70 GHz. The chip packs the Arc B370 iGPU, based on the Xe3 graphics architecture, and comes packed with 4 Xe3 cores. The CPU itself has 4 P-Cores, 4 E-Cores & 4 LP-E cores. We covered the performance of this CPU yesterday, which you can check out over here.
The leak confirms that Samsung's Galaxy Book6 Pro and Galaxy Book6 laptops will feature Intel Core Ultra Series 3 "Panther Lake" CPUs. There are some new AI benchmarks, but they were run on the CPU using the ONNX framework, so not much to see here. If it were tested on the iGPU or the NPU, then we could've seen a better representation of generational uplifts from Arrow Lake and Lunar Lake.
So, it looks like the Intel Panther Lake CPUs should turn up to be a decent offering for mobility platforms. As always, take these numbers with a grain of salt. Intel is expected to release its first Panther Lake SKU in this quarter, with more SKUs and an official launch slated for CES 2026 in January.
