Oracle’s Processor Core Factor Table is crucial in determining how many licenses you need for your Oracle software deployments. Whether you’re operating Oracle on physical servers or in cloud environments, understanding core factors can save you hundreds of thousands or even millions of dollars while avoiding costly audit findings. With Oracle’s May 2025 updates, staying updated with the core factors is even more essential. To ensure you’re following the latest guidelines, refer to our Oracle Processor License Counting Cheat Sheet here.

In this guide, we’ll walk you through all the vital information you need to know about the Oracle Processor Core Factor Table in 2025, including the latest updates, cloud environment basics, and easy ways to calculate the correct licenses to avoid costly errors.

Key Highlights:

These are the key facts that every Oracle customer should know before diving into the details:

• The Core Factor Table directly affects licensing costs – a 0.25 core factor means 75% fewer licenses than a 1.0 core factor. For more on Oracle’s licensing metrics, visit Oracle Legacy License Metrics.
• Oracle’s May 2025 updates introduced new AMD EPYC and Intel Xeon processors with favorable 0.5 core factors.
• Cloud environments, such as Oracle Cloud Infrastructure, require different calculations than on-premises deployments.
• Miscalculating core factors is one of the leading causes of costly Oracle audit findings.
• Choosing the right processor can reduce your Oracle licensing costs by half.

What Is The Oracle Processor Core Factor Table?

The Oracle Processor Core Factor Table is a system that adjusts licensing requirements based on different CPU types. Instead of a simple license per physical core, Oracle uses core factors to determine how many licenses are needed based on the processing power of each core. For more understanding of Oracle’s core factor tables, see the Oracle Processor License Counting Cheat Sheet.

Here’s how it works:

• Intel Xeon Platinum processors have a 0.5 core factor, meaning you need half the licenses compared to a 1.0 factor.
• IBM Power systems typically have a 1.0 core factor – requiring full licensing per core.
• Ampere Altra processors have a favorable 0.25 core factor, meaning you only need a quarter of the licenses.
• The table adjusts for the fact that modern processors, like Intel Xeon, deliver significantly more processing power than older architectures. For further insights, review the Complete Guide to Oracle Unlimited License Agreements (ULA).

How to Calculate Oracle Processor Licenses Using Core Factors

The formula is simple:
Required Processor Licenses = (Total Physical Cores × Core Factor), rounded to the nearest whole number.

Examples:

1. Intel Xeon Platinum:
   • Server: Dell PowerEdge with 2 × Intel Xeon Platinum 8380 processors
   • Physical cores per processor: 40
   • Total physical cores: 80
   • Core factor: 0.5
   • Calculation: 80 × 0.5 = 40 Processor licenses required
2. IBM Power10 System:
   • Server: IBM Power10 system with 2 processors
   • Physical cores per processor: 15
   • Total physical cores: 30
   • Core factor: 1.0
   • Calculation: 30 × 1.0 = 30 Processor licenses required
3. Ampere Altra Processors:
   • Server: System with 4 × Ampere Altra processors
   • Physical cores per processor: 80
   • Total physical cores: 320
   • Core factor: 0.25
   • Calculation: 320 × 0.25 = 80 Processor licenses required

2025 Updates to the Oracle Core Factor Table

Oracle continuously updates the Core Factor Table to include new processor architectures. The May 2025 updates included several key additions:

• AMD EPYC Processors (May 2025)
  • AMD EPYC 9xx5, 9xx5F, 9xx5P (5th generation) – Core factor: 0.5
  • AMD EPYC 9xx4F, 9xx4P (4th generation expansion) – Core factor: 0.5
  • AMD EPYC 7xx3P (3rd generation expansion) – Core factor: 0.5
• Intel Processor Updates (April 2025)
  • Intel Xeon 69xxP, 67xxE, 67xxP, 65xxP – Core factor: 0.5
  • Intel Xeon E-24xx – Core factor: 0.5

These updates continue Oracle’s trend of providing favorable core factors for modern processors, helping you to achieve better price-performance when upgrading your infrastructure. For more on processor updates, refer to our Oracle Processor License Counting Cheat Sheet here.

Oracle Cloud Infrastructure (OCI) Special Considerations

In Oracle Cloud, licensing differs from conventional on-premises deployments.

• OCPU to Processor License Mapping:
  • x86 Platform (Intel/AMD): 1 Processor license = 2 OCPUs
  • Ampere Platform (Altra/AltraMax): 1 Processor license = 4 OCPUs
• Named User Plus Minimums:
  For programs requiring 25 NUP per Processor:
  • x86: Minimum 25 NUP per 2 OCPUs
  • Ampere: Minimum 25 NUP per 4 OCPUs

Common Mistakes and Pitfalls in Core Factor Calculations

1. Using Incorrect Core Factors
   • Always use the current Oracle Processor Core Factor Table to avoid miscalculations.
2. Miscounting Physical Cores
   • Avoid confusing logical cores with physical cores. Verify actual physical core counts using hardware specifications.
3. Overlooking Cloud-Specific Rules
   • Cloud deployments like Oracle Cloud have different rules, so make sure to follow specific cloud licensing guidance.

Oracle Audit Implications

Incorrect core factor calculations are among the most common findings in Oracle audits. To protect your organization:

• Keep detailed documentation of core counting methodologies.
• Regularly conduct compliance reviews using the current core factor table.

Conclusion

Understanding Oracle’s Processor Core Factor Table is essential for optimizing Oracle software licensing. The 2025 revisions offer significant benefits for those upgrading to modern processors.

Always stay updated with the latest changes, and ensure your hardware selection aligns with the most cost-effective licensing options. If in doubt, consider scheduling a consultation with an Oracle licensing specialist.
