Beyond RaspberryPi: What are all the other SoC vendors up to *summarised* (sbcwiki.com)

Q4 2025 brought a flurry of ARM SoC momentum that’s pushing SBCs into more capable, AI-ready territory and squeezing x86 niches. NVIDIA shipped the DGX Spark powered by the GB10 (Grace Blackwell) Superchip — 20 Arm cores (10x Cortex‑X925 + 10x A725), 128 GB unified memory and a Blackwell GPU with 6,144 CUDA cores, 5th‑gen Tensor Cores and FP4 support — at a $3,999 MSRP; higher‑end Blackwell Ultra systems (72 CPU cores, massive LPDDR/HBM pools) promise trillion‑parameter model reach. Qualcomm confirmed Snapdragon Oryon X2 (first mainstream Arm at ~5 GHz) and expanded its footprint with Dragonwing QCS boards (Radxa Dragon Q6A) offering full mainline support, a $599 Radxa Airbox Q900 (200 TOPS) and a surprise Arduino UNO Q SBC ($44) using QRB2210. Rockchip unveiled RK3688/RK3668 roadmaps (RK3688: 12 cores 8x A730+4x A530, 8‑channel LPDDR5/6 ~200 GB/s, >2 TFLOPS GPU, 32 TOPS NPU, 16K decode) while MediaTek focused on upstream support and shipped the Dimensity 9500 (strong GeekBench6 scores, Mali‑G1 Ultra MC12 GPU). Raspberry Pi updated the Pi 500+ with an M.2 slot. Software and ecosystem work is the other headline: mainline kernel updates, PanVK Vulkan progress on Mali, and device‑tree moves for CIX’s Orion chips are improving long‑term support and interoperability. This quarter shows two trends: AI acceleration is getting affordable at the edge (hundreds, not tens of thousands of dollars) and vendor emphasis on upstream drivers is reducing BSP fragmentation — a meaningful shift for developers building production or hobbyist AI/ML workloads on SBCs.
