What CPUs are supported in Oracle x86 servers?
While Oracle is famous for its custom SPARC processors, its x86 server line is a high-performance home for Intel and AMD chips. Oracle doesn't just use any off-the-shelf processor; they select specific "Skus" optimized for the heavy thermal and data-throughput demands of the Oracle Database.
As of 2026, here is the breakdown of the CPUs powering the Oracle x86 lineup.
Oracle has shifted to a "best-of-breed" approach, using Intel for its flagship general-purpose servers and AMD for its high-density "scale-out" systems.
Oracle uses Intel Xeon Scalable Processors (3rd and 4th Generation) in its core X-series servers.
X9-2 Series: Uses 3rd Gen Intel Xeon "Ice Lake" (e.g., Xeon Platinum 8358). These support up to 32 cores per socket and are the backbone of the Exadata X9M.
X10 Series: Uses the latest Intel Xeon Scalable processors, pushing core counts and adding support for DDR5 memory and PCIe 5.0.
In a major architectural shift with the Exadata X10M, Oracle introduced AMD EPYC™ processors to achieve massive core density.
CPU: 4th Gen AMD EPYC (e.g., 9334 series).
Power: A single X10M database server can pack two 96-core processors, providing a staggering 192 cores in a single server.
Oracle Database Appliance (ODA) X10: Also uses AMD EPYC 9334 processors (32-core variants) to balance cost and performance.
If you are managing older hardware, Oracle’s x86 servers have followed the evolution of Intel’s Xeon roadmap:
| Server Generation | CPU Architecture | Max Cores per Socket |
| X8-2 / X8-8 | Intel Xeon Scalable 2nd Gen (Cascade Lake) | 24–28 Cores |
| X7-2 / X7-8 | Intel Xeon Scalable 1st Gen (Skylake) | 24 Cores |
| X6-2 | Intel Xeon E5-2600 v4 (Broadwell) | 22 Cores |
| X5-2 | Intel Xeon E5-2600 v3 (Haswell) | 18 Cores |
| X4-2 | Intel Xeon E5-2600 v2 (Ivy Bridge) | 12 Cores |
Oracle's hardware team selects processors based on three "Database-First" criteria:
High Frequency: Databases love "Single-Threaded" speed for complex joins. Oracle often picks chips that maintain a high base clock (e.g., 2.7 GHz to 3.0 GHz) rather than low-power variants.
Large L3 Cache: Database indexes live and die by cache hits. Oracle servers utilize the "Platinum" and "Gold" tiers of Intel and high-cache AMD EPYC models to keep more data close to the execution units.
Memory Channels: Modern Oracle x86 servers (X9 and X10) leverage 8 to 12 memory channels per CPU, ensuring the massive "Smart Scans" in Exadata aren't starved for data.
When choosing a CPU for an Oracle x86 server, you have to remember the Oracle Processor Core Factor Table.
For almost all modern x86 (Intel and AMD) processors, the core factor is 0.5.
The Math: If you buy a server with 64 cores, you generally need to pay for 32 Oracle Database licenses.
Pro-Tip: This is why "Capacity-on-Demand" is so popular on the Oracle Database Appliance (ODA). You can have a 32-core AMD chip but "disable" 28 of them in software, only paying for the 4 licenses you actually need today.
In 2026, Oracle's x86 architecture is dominated by Intel Xeon Scalable for high-performance single-thread tasks and AMD EPYC for massive, high-density consolidation. Whether it's the 64-core Intel X9-2 or the 192-core AMD X10M, the goal remains the same: provide the fastest possible path for the Oracle Database.
