This translates to a significant performance boost, delivering up to 13% higher base frequency, 33% faster memory, and double the network bandwidth per bare metal instance.
- X12 Standard Acceleron: Replacing the X9 Standard, these instances are powered by the cutting-edge Intel Xeon 6 processors (specifically the 6900 series with P-cores). For bare metal instances, engineers can expect up to 2.5x CPU performance, while VM instances see up to a 50% improvement. Furthermore, X12 offers 42% higher memory bandwidth, crucial for high-performance and latency-sensitive applications. Key enhancements include double the core density for greater workload consolidation and improved per-core performance with enhanced IPC and up to 12% higher max turbo frequency. Built-in AI acceleration is provided by Intel AMX (Advanced Matrix Extensions), boosting performance for inference and AI-driven applications.
Oracle Acceleron SmartNIC: The Network Advantage
A pivotal innovation within the new Acceleron shapes is the introduction of the Oracle Acceleron SmartNIC. This represents OCI’s first host network accelerator capability from the broader Oracle Acceleron suite. The SmartNIC delivers two fundamental benefits:
- Higher Throughput and Advanced Capabilities: It significantly enhances network performance, crucial for distributed applications and data-intensive tasks.
- Enhanced NVMe Storage Attachments: By offloading network and storage processing from the main CPU, the SmartNIC improves the efficiency and performance of NVMe-based storage.
- Automated HostNIC Patching: This feature simplifies maintenance and improves security posture by automating updates to the network interface, reducing operational overhead.
Cost Efficiency and Transparent Pricing
Beyond raw performance, OCI is committed to transparent and competitive pricing. The new Oracle Acceleron family boasts OCPU-hour prices that are up to 70% lower than the previous generation. While memory pricing now reflects the market reality of increasing memory costs, OCI maintains separate visibility into OCPU/hr and memory/hr pricing. This granular transparency allows customers to more accurately evaluate workload fit, price-performance, and the trade-offs between compute and memory, ensuring stronger efficiency across a broad range of use cases.
