Mac-rivaling Nvidia RTX Spark Lenovo mini PC revealed: Surprise port selection, up to 128GB RAM

Notebookcheck's Martin Filipov reveals the Lenovo SFF RTX Spark mini PC at Computex 2026, one of five RTX Spark compact desktops unveiled at the show — and Lenovo's first mini PC to feature NVIDIA's Arm-based superchip. The machine sports a minimalist dual-tone design in black and silver, but notably lacks the front-facing I/O found on Dell's competing XPS RTX Spark Desktop, which offers two USB-C ports and an SD card reader on the front panel. Instead, Lenovo has opted to place all connectivity on the rear — a decision that prioritizes clean aesthetics but may frustrate users who frequently swap peripherals. Despite being officially revealed at Computex, Lenovo has remained one of the most secretive OEMs, publishing no formal press release and leaving many specifications to be inferred from NVIDIA's platform announcements and hands-on previews.

The rear port selection carries some surprises: one USB-C port with Power Delivery for charging the host device, two high-speed USB-C ports rated for 20Gbps data transfer, one HDMI port for video output, and a 10Gb LAN port — a standout inclusion that positions the Lenovo SFF RTX Spark as a serious contender for networked AI development workstations and creative studios that demand high-bandwidth local connectivity. The 10GbE port is particularly noteworthy given that it matches the connectivity specs previously confirmed for ASUS, Dell, and MSI RTX Spark mini PCs, suggesting NVIDIA has standardized high-speed networking across the compact desktop category. Combined with the RTX Spark platform's Wi-Fi 7 and Bluetooth 5.4 support, the Lenovo SFF offers comprehensive wired and wireless connectivity for professional environments.

Under the hood, the Lenovo SFF RTX Spark leverages the same platform as the newly announced Yoga Pro 9n laptop, with the RTX Spark available in two tiers: the premium N1X and the mainstream N1. Notebookcheck reports that the system supports up to 128GB of unified LPDDR5X memory with 300GB/s of memory bandwidth, enables 12K video editing workflows, and delivers up to 1 petaflop of AI performance for on-device large language model inference — specifications that position it as a direct competitor to Apple's Mac Studio for AI development and creative workloads. Unlike the ASUS and Microsoft RTX Spark designs that push up to 140W and 110W TDP respectively, Lenovo has not disclosed the thermal ceiling for the SFF, leaving open questions about sustained performance under heavy workloads. Pricing, availability, and detailed configurations remain unannounced, though the device is expected to launch alongside other RTX Spark systems in the Fall 2026 window.
