GPUs in Base Stations? AI-RAN Debate

🔑 Enhanced Key Takeaways

• •MSI unveiled GPU-accelerated servers like CG480-S6053 (up to 8 GPUs) and CG290-S3063 (2U edge-optimized) at MWC 2026 for unified AI-vRAN across O-RAN and private 5G[1].
• •SoftBank and Nokia's Japan experiment uses GPUs in base stations for 5G during day and third-party AI inference at night via AITRAS orchestrator[2].
• •SK Telecom demonstrated AI-RAN with Nokia and HFR, processing comms and AI on GPUs or hybrid with dedicated accelerators in real networks[4].
• •SynaXG achieved 36 Gbps throughput and <10ms latency on NVIDIA GH200 for FR2 mmWave AI-RAN with 20 component carriers[3].
