🧠 Food for thought

Implications, context, and why it matters.

SoftBank paid less despite Ampere’s wider customer list

SoftBank bought Ampere for $6.5 billion 1. That price sat below the roughly $8 billion valuation when it weighed a minority stake in 2021 1. Customers include Google Cloud and Microsoft Azure 1. HPE and server maker Supermicro join Alibaba and Tencent as customers 1.
Pricing likely reflects pressure from hyperscalers (very large cloud providers) building in-house Arm CPUs 2 3. Microsoft’s Azure Cobalt offers 8.8% lower cost than Ampere-based Azure instances 2. AWS Graviton spurred rivals to design custom silicon 3.
Ampere’s share of Arm-based cloud instances fell from over 20% to 18.2% by December 2024 after Azure Cobalt and Google Axion launched 2.

Enterprise software makers should port to Arm on Oracle Cloud A4

Oracle’s A4 instances were expected to launch in November 2025 4. Regions include Ashburn and Phoenix 4. Frankfurt and London are also planned 4. They bring up to 45% higher per-core performance than A2 and about 30% better price-performance than AMD EPYC-based Oracle Cloud Infrastructure (OCI) E6 shapes (instance types) 5. That gives more than 1,000 A1/A2 customers a reason to move in over 65 regions 4.
Independent software vendors selling into Oracle’s customer base should tune for A4’s 12-channel Double Data Rate (DDR) 5 memory and 3.6 GHz cores 4. Oracle is expanding internal use of Ampere processors for Fusion Applications (Oracle’s enterprise app suite) and Block Storage (its cloud storage service) 4.
Teams can use Oracle’s developer images (preconfigured virtual machine images) for Java, Python, and Node.js 6 plus Ampere’s AI Playground (a developer resource with pre-built demos) 4 to speed Arm-native builds.
