System76 has provided the first concrete specifications for its upcoming Adder Pro 15.3 laptop, revealing a machine built around Intel's Panther Lake platform and NVIDIA's next-generation RTX 50-series graphics. This announcement matters because it confirms the availability of high-end RTX 5060 and RTX 5070 options in a Linux-native gaming chassis, offering a specific alternative to mainstream Windows rigs for enthusiasts who prefer open-source software. The device targets users who need powerful hardware for gaming or development without compromising on their preferred operating system environment.

Linux-focused brand targets gamers with next-gen NVIDIA graphics
The laptop centers on the Intel Core Ultra 7 356H processor, which System76 identifies as part of the Panther Lake platform. This 16-core chip combines four performance cores, eight efficiency cores, and four low-power efficiency cores to reach a maximum frequency of 4.7 GHz. System76 positions this configuration as the primary engine for the Adder Pro 15.3, ensuring sufficient computational headroom for demanding workloads alongside the dedicated graphics hardware.
Specifications
- Processor: Intel Core Ultra 7 356H (16 cores)
- Graphics: NVIDIA RTX 5060 or RTX 5070 (8GB GDDR7)
- Display: 15.3-inch QHD+ OLED (100% DCI-P3)
- Memory: Up to 96GB DDR5-5600
- Storage: Up to 4TB SSD (PCIe 4.0)
Graphics performance relies on optional NVIDIA GeForce RTX 5060 or RTX 5070 GPUs, both equipped with 8GB of GDDR7 video memory. The system supports up to 96GB of dual-channel DDR5-5600 memory and includes a single M.2 2280 PCIe 4.0 x4 slot for storage expansion up to 4TB. Visual output comes from a 15.3-inch QHD+ (2560×1660) OLED panel that covers 100% of the DCI-P3 color gamut, providing high fidelity for creative work or gaming.
Connectivity features include Wi-Fi 7 and Bluetooth 6, alongside a 5-megapixel webcam and Gigabit Ethernet port. The chassis measures 34.37 by 26.19 by 1.98 cm and weighs 1.52 kg, powered by a 60Wh internal battery. While the source material lists Bluetooth 6, this designation remains unconfirmed as the standard is not yet widely released, and the specification may reflect a future update or reporting error. The device is scheduled for global availability in mid-July.
We touched on System76 Lemur Pro Brings Intel Panther in our earlier System76 coverage, which highlights the vendor's broader shift toward this new processor architecture across its product line. The Adder Pro 15.3 stands as the gaming-focused counterpart to those ultrabook releases, cementing System76's entry into the Panther Lake gaming segment. Buyers can expect the hardware to ship with Linux preinstalled, aligning with the brand's established identity in the developer and enthusiast markets.
