For the first time, the Lemur Pro ships in two sizes, giving System76's featherweight Linux notebook a 16-inch sibling alongside the 14-inch model that has anchored the line for six years. Both run on Intel's newest Panther Lake silicon, and both arrive with the company's own Linux stack rather than Windows.
The refreshed Lemur Pro scales up to a 16-core Intel Core Ultra X7 358H, a Panther Lake part paired with 12-core Intel Arc B390 integrated graphics. The 14-inch version starts with an 8-core Core Ultra 325 and 4-core integrated graphics but can be configured with the faster chip, while the 16-inch model comes exclusively with the X7 358H. That matters for anyone who wants to game or push GPU-accelerated workloads on Linux: the Arc B390 rides on Intel's open-source graphics drivers, and recent Phoronix testing found the Panther Lake SoC delivering strong generational gains and notably better performance-per-watt on Ubuntu, with titles like Cyberpunk 2077 hitting playable frame rates at 1080p on the integrated GPU.
The two machines share most of their spec sheet. Each ships with 32GB of LPDDR5x-7467 memory, an M.2 2280 slot for up to 4TB of PCIe 4.0 NVMe storage, a 73 Wh battery with a 65W USB-C adapter, WiFi 7, Bluetooth 6, and a matte, backlit-keyboard build with a multitouch trackpad. Ports include Thunderbolt 4, HDMI, USB 3.2 Gen 2 Type-C and Type-A, USB 3.2 Gen 1 Type-A, a 3.5mm jack, and a microSD reader. The 14-inch panel runs at 1920 x 1200 while the 16-inch steps up to 2560 x 1600, and the larger chassis adds a numeric keypad. The smaller model stays true to the Lemur Pro's ultraportable roots at 1kg (2.2 pounds) and 17mm (0.67 inches) thick, while the 16-inch version weighs 1.34kg (3 pounds) and measures 20mm (0.77 inches).
System76 pre-installs either Ubuntu or its own Pop!_OS, which shipped its 24.04 LTS release in December 2025 built around the Rust-based COSMIC desktop. COSMIC is Wayland-native and, thanks to Rust's memory safety, sidesteps entire classes of bugs like buffer overflows and use-after-free; it has also spread well beyond Pop!_OS to Fedora, Arch, openSUSE Tumbleweed, NixOS, and others. Buyers who want a harder security posture can order a Lemur Pro with the microphone and webcam disabled, the WiFi and Bluetooth card removed, or both, at no change in price. Both models ship with System76's open firmware, a stack built on coreboot and EDK2 that replaces the proprietary BIOS found on most laptops and disables the Intel Management Engine by default. The embedded controller firmware, which governs keyboard input, fan control, and battery management, is published separately under the GPLv3 at github.com/system76/ec.
Retail pricing starts at $2,000 (€1,840) for the entry-level 14-inch configuration and $2,360 (€2,170) for the 16-inch model. A launch promotion drops those to $1,920 (€1,770) and $2,280 (€2,100) respectively.
