The deal is the largest single investment in AI‑accelerated hardware by a Japanese conglomerate and marks a decisive pivot toward monetizing generative‑AI infrastructure at enterprise scale. Why Ampere’s Silicon Is a Game Changer for Generative AI Arm‑based efficiency: The Ampere Altra S1000 , built on a 12 nm process, delivers 1.6 TFLOP/s of FP16 throughput at just 60 W per core—outpacing NVIDIA’s A6000 in power‑per‑performance for inference. Quantization readiness: Ampere’s cores natively support 4‑bit quantized transformer workloads, enabling models such as GPT‑4o , Claude 3.5 , and Gemini 1.5 to run with sub‑30 ms latency on a single 1k‑token prompt. Edge‑to‑cloud integration: The company’s “Ampere Cloud” stack couples silicon with open‑source container orchestration, allowing seamless scaling from edge nodes to public cloud backends. Deal Mechanics and Upside Levers SoftBank paid $75 per share in cash, valuing Ampere at roughly $6.5 B. The transaction includes a $500 M earn‑out tied to the delivery of three new silicon variants (Altra S1100, Altra A800, and a custom “Ampere Enterprise” line) by Q4 2026. SoftBank also secured a 10% stake in Ampere’s forthcoming
