Our Verdict on Each
A solid mainstream workstation CPU with strong per-core performance, generous PCIe 5.0 lanes, and modern platform features, though it is locked and faces tough competition from higher-core Xeon W and AMD Threadripper Pro parts in heavily threaded workloads.
Best for: Building a single-socket workstation for CAD, 3D rendering, or AI development where you need high single-thread performance, ECC memory, and lots of PCIe 5.0 lanes, but do not require more than 8–12 cores.
Read the full reviewA capable 18-core workstation chip with strong I/O and memory bandwidth, suited for professionals who value PCIe 5.0 expansion and ECC DDR5. However, efficiency and platform costs make it less appealing versus mainstream desktops for lighter workloads.
Best for: Buy for professional workstations that need multiple high-speed expansion cards, large ECC memory, and sustained multi-core compute.
