Lenovo’s SFF RTX Spark pairs Blackwell graphics with up to 128GB of LPDDR5X unified memory and 10GbE networking in a compact desktop chassis. The small-form-factor PC was displayed during Computex 2026 and joins a growing number of desktops built around NVIDIA’s RTX Spark platform.
The desktop follows a compact black-and-silver design with all connectivity positioned on the rear panel. Unlike many mini PCs that place USB ports and card readers on the front, Lenovo has opted for a cleaner front face while moving every external connection to the back of the chassis.
The rear I/O consists of a USB-C port with Power Delivery support, two additional 20Gbps USB-C ports, an HDMI output, and a 10Gb Ethernet connection. The addition of 10GbE networking is particularly noteworthy, as it remains uncommon in compact desktops and is more frequently found on workstation and enterprise hardware.
Lenovo has not disclosed final configuration options, but the desktop is based on NVIDIA’s RTX Spark platform. According to NVIDIA’s published specifications, RTX Spark supports up to 20 Arm-based CPU cores derived from the Grace architecture alongside up to 6,144 Blackwell CUDA cores.
Memory support is up to 128GB of LPDDR5X unified memory with bandwidth of up to 300GB/s. Unlike traditional desktop designs that separate CPU and GPU memory, RTX Spark allows both processing components to access the same memory pool. This approach can help improve efficiency when working with large datasets, rendering projects, and compute-heavy workloads.
The platform is designed to support a broad range of professional applications. NVIDIA lists support for CUDA-accelerated software, rendering applications, software development workloads, simulation projects, and high-resolution media production.
Content creators working with large video files may find the platform particularly interesting. NVIDIA states that RTX Spark hardware is capable of supporting demanding production workloads, including high-resolution video editing and real-time rendering tasks.
The platform supports ray tracing, DLSS, NVIDIA Reflex, and G-SYNC technologies. NVIDIA claims RTX Spark hardware can deliver 1440p gaming performance while retaining the compute capabilities required for professional workloads.
A notable advantage of the platform is its ability to run demanding workloads locally. With up to 128GB of unified memory, RTX Spark desktops can work with far larger datasets and applications than many compact PCs. The expanded memory capacity gives developers, engineers, researchers, and content creators greater flexibility for complex projects, reducing the need to move tasks to external resources.
Lenovo has not disclosed thermal specifications for the SFF RTX Spark. ASUS previously confirmed a 140W thermal envelope for its own RTX Spark desktop, but Lenovo has yet to provide comparable details regarding cooling capacity or sustained power limits.
Storage configurations, pricing, and availability remain unknown. Lenovo has not announced when the SFF RTX Spark will reach retail channels or which hardware variants will be offered at launch.
