About this tag
The xeon 678x tag on WindowsForum.com collects discussion of Intel's 48-core, 96-thread Xeon 678X workstation processor and how it compares with competing high-core-count CPUs. Coverage centers on Phoronix workstation testing that measured simultaneous multithreading, finding an aggregate gain of about 11% for Intel Hyper-Threading when SMT stays enabled. The practical takeaway for developers, render farms, and CPU-based AI or content-creation workstations is to leave the second hardware thread per core enabled unless a specific, measured workload proves otherwise. Related threads also touch AMD's Ryzen Threadripper 9980X and HP Z4 G6i and System76 Thelio Major configurations.

    Xeon 678X and Threadripper 9980X: Keep SMT On

    Phoronix’s new workstation testing finds that leaving simultaneous multithreading enabled delivers a meaningful aggregate gain on both Intel’s Xeon 678X and AMD’s Ryzen Threadripper 9980X: 11% for Intel Hyper-Threading and 16% to 18% for AMD SMT across its test suite. For developers, render...
