Oracle Has One Last Ampere Hurrah - New Cloud Platforms Offer up to 192 Custom Arm Cores, and Aren't OCI Exclusive, Unlike Graviton or Cobalt

Why It Matters

Oracle’s non‑exclusive Arm offering expands choice for enterprise workloads and pressures rivals to open their proprietary silicon, while its chip‑neutral stance could reshape cloud supplier dynamics.

Key Takeaways

• Oracle offers up to 192 Arm cores per chip.
• A4 instances available both virtualized and bare‑metal, non‑OCI exclusive.
• Up to 35% performance boost over previous A2 generation.
• Pricing starts at $0.0138 per OCPU‑hour, $0.0027 per GB‑hour.
• Oracle adopts chip‑neutrality, selling Ampere stake for flexibility.

Pulse Analysis

Arm‑based processors have become a cornerstone of modern cloud strategies, delivering energy efficiency and competitive performance for a range of workloads. Oracle’s decision to introduce AmpereOne M‑powered A4 instances marks a notable shift, as the company moves from proprietary silicon to a more open, multi‑vendor approach. By offering up to 192 custom Arm cores per chip, Oracle positions itself to attract customers seeking high‑core density without being locked into a single cloud ecosystem, a contrast to Amazon’s Graviton and Microsoft’s Cobalt which remain exclusive to their platforms.

The technical specifications of the A4 line underscore Oracle’s focus on raw performance and flexibility. Virtual machines can provision up to 45 OCPUs (90 cores) with 700 GB of memory, while bare‑metal options push the envelope to 48 OCPUs, 96 cores, 768 GB DDR5, and 3.84 TB of onboard storage, all backed by up to 100 Gbps network bandwidth. Oracle claims a 35 % core‑for‑core uplift over the A2 generation, driven by a 20 % higher clock speed and a 12‑channel memory controller. At $0.0138 per OCPU‑hour and $0.0027 per GB‑hour, the pricing is competitive for enterprises looking to scale Arm workloads cost‑effectively.

Strategically, Oracle’s chip‑neutrality policy signals a broader industry trend toward diversified silicon supply chains. By divesting its stake in Ampere and pledging to work with multiple CPU and GPU vendors, Oracle reduces dependency risk and opens the door for cross‑cloud collaborations. This stance may compel other cloud providers to reconsider exclusive silicon roadmaps, potentially accelerating the availability of high‑core Arm instances across the market and fostering greater competition on performance, price, and openness.
