HP showed a prototype mini PC at Computex 2026 that runs on Nvidia's RTX Spark platform. The machine targets creative professionals and gamers who want a compact system with workstation-class performance.
Prototype features dual ConnectX-7 ports
The unnamed mini PC uses Nvidia's Grace CPU and Blackwell GPU architecture. It packs up to 20 Arm-based CPU cores and up to 6,144 CUDA cores. The system also includes two Nvidia ConnectX-7 network ports, though HP has not confirmed whether those will ship on retail units.
Specifications
- AI performance: Up to 1 petaflop (FP4 precision)
- Unified memory: Up to 128 GB LPDDR5X
- Memory bandwidth: Up to 300 GB/s
- GPU cores: Up to 6,144 Blackwell CUDA cores
- CPU cores: Up to 20 Arm-based cores (Grace microarchitecture)
HP rates the mini PC at up to 1 petaflop of AI performance using FP4 precision. It supports up to 128 GB of LPDDR5X unified memory with 300 GB/s of bandwidth. HP claims the system can handle 12K video editing and 1440p AAA gaming.
The design is bold, according to HP, but the final name has not been decided. The ports on the prototype are unlabeled, suggesting it is still a work in progress. HP has not announced pricing or availability.
