Xeon Gold 6438Y+ Details

As of March 2026, the Intel Xeon Gold 6438Y+ remains a high-end server processor, showcasing the company's commitment to performance in multi-threaded workloads. Launched in January 2023, this processor is built on the Sapphire Rapids-SP architecture and is designed for demanding server and workstation environments. With a base clock of 2.0 GHz and a turbo frequency reaching 4.0 GHz, the Xeon Gold 6438Y+ is optimized for sustained high-throughput computing, though its 205 W TDP demands robust cooling and power delivery. The processor features 32 cores and 64 threads, leveraging Intel Hyper-Threading to deliver exceptional parallel processing capabilities.

The Xeon Gold 6438Y+ operates on a 10 nm manufacturing process and uses the Socket 4677 platform, supporting up to two CPUs in a symmetric multiprocessing (SMP) configuration. This makes it suitable for high-density server deployments where scalability is critical. The processor supports DDR5 memory at up to 4800 MT/s through an eight-channel memory interface, enabling a peak memory bandwidth of 307.2 GB/s. It also includes 60 MB of L3 cache, which enhances data access speed for memory-intensive tasks. While it lacks integrated graphics, the absence of a GPU is typical for server-focused CPUs, allowing system designers to allocate resources to dedicated graphics solutions.

Intel’s inclusion of advanced instruction sets such as AVX-512, AVX2, and SSE extensions ensures the Xeon Gold 6438Y+ is capable of accelerating scientific computing, data analytics, and virtualization workloads. It also supports hardware virtualization technologies like Intel VT-x and VT-d, along with Intel vPro for enhanced manageability in enterprise environments. The processor supports PCIe 5.0 with 80 lanes directly from the CPU, facilitating high-speed connectivity for storage and accelerators.

In benchmark testing, the Xeon Gold 6438Y+ achieves an Overall Score of 6,433, placing it at #128 among 2,060 processors. Its Singlecore Score of 5,872 ranks it #320, indicating strong performance in single-threaded applications, though it trails behind the latest consumer-grade CPUs like the Core Ultra 9 285K. The Multicore Score of 7,275 positions it at #75 in the multicore category, highlighting its strength in parallel processing. This performance gap is particularly evident when compared to top-tier processors like the Ryzen Threadripper PRO 9995WX, which scores 12,029 in multicore tests.

Despite its strong multicore performance, the Xeon Gold 6438Y+ is outperformed by newer Intel and AMD processors in both single-threaded and overall performance categories. Its positioning suggests it is best suited for data centers, cloud computing, and professional workstations where high thread counts and memory bandwidth are prioritized over raw single-core speed. While it may not be the fastest CPU available, its combination of scalability, ECC memory support, and enterprise-grade features makes it a reliable choice for mission-critical applications.
