よくある質問（FAQ）

Q1: Hyperscaler Cobalt 100 / Axion 進出影響 Ampere customer base は？ A: Microsoft Azure Cobalt 100 transition 2024年Q3予定 + Google Cloud Axion transition 2024年Q3予定 → Ampere customer base partial loss risk (Microsoft + Google = Ampere customer Top 5 → Top 5から2社 loss potential)・Multi-cloud customer diversification critical strategy + Oracle Cloud Infrastructure + Hetzner + 多Multi-tenant Cloud platforms + Enterprise on-premise deployment expansion + Long-term customer base evolution。

Q2: 192 cores Industry-leading core density 持続性は？ A: 192 cores Aurora (2024年Q4・Industry-leading) → 次世代AmpereOne family successor (2025-2026年 future generations) で更多cores potential (256 cores + 等)・但しCore count race Industry-wide (Intel Sierra Forest E-core 288 cores + AMD EPYC Bergamo 128 cores・AWS Graviton next-gen + Microsoft Cobalt next-gen + Google Axion next-gen) で Industry catch-up + Aurora Industry-leading position 期限あり + 継続evolution必要。

Q3: Custom cores vs Neoverse IP licensing 長期影響は？ A: Custom cores (Ampere + AWS Graviton custom approach) = Differentiation + Custom architecture deep optimization + IP licensing fees savings + Long-term cost optimization・但しCustom architecture design risk + Long-term sustainability concerns + Higher design cost・Neoverse IP licensing (Microsoft Cobalt 100 + Google Axion) = Risk minimization + Time-to-market faster + Industry-standard alignment・Long-term Architecture flexibility + Custom approach evolution potential。
