**Samsung’s Upcoming Galaxy Book6 Pro Featuring Intel Core Ultra Series 3 “Panther Lake” CPU Leaked**

Laptop OEMs are gearing up to launch their next-generation devices based on Intel’s upcoming Core Ultra Series 3 “Panther Lake” CPUs. These new laptops promise faster performance, advanced features, and improved efficiency. Among the notable upcoming releases, Samsung is preparing to unveil its new Galaxy Book6 series, which has recently been leaked.

### Galaxy Book6 Pro Spotted on Geekbench

The Samsung Galaxy Book6 Pro has surfaced on Geekbench, confirming that it will be powered by Intel’s Core Ultra Series 3 “Panther Lake” processors. So far, only one configuration has been revealed, featuring the Intel Core Ultra 5 338H CPU — a mainstream design that balances solid compute power with capable graphics performance.

### Intel Core Ultra 5 338H Specifications

According to the leak, the Intel Core Ultra 5 338H “Panther Lake” CPU operates with a base clock of 1.90 GHz and can boost up to approximately 4.70 GHz. This chip incorporates the Arc B370 integrated GPU, which is based on Intel’s Xe3 graphics architecture and includes 4 Xe3 cores.

On the CPU side, the Core Ultra 5 338H comes equipped with a hybrid core design:

– 4 Performance Cores (P-Cores)
– 4 Efficiency Cores (E-Cores)
– 4 Low-Power Efficiency Cores (LP-E Cores)

This configuration is intended to deliver a balanced mix of power and efficiency, making it well-suited for mobile computing.

### AI Benchmarks and Performance Insights

There have also been some AI benchmarks conducted on this CPU using the ONNX framework, but since these tests were run solely on the CPU (and not utilizing the integrated GPU or dedicated neural processing units), they do not fully showcase the generational improvements expected from Panther Lake compared to Intel’s previous Arrow Lake and Lunar Lake architectures.

Overall, Intel’s Panther Lake CPUs look promising as a strong choice for mobility platforms, although it’s wise to view early benchmark data cautiously until official reviews and testing are available.

### Expected Release Timeline

Intel is projected to release its first Panther Lake SKU within this quarter, with a broader lineup and an official launch anticipated at CES 2026 in January.
