About this tag
The threadripper 9980x tag on WindowsForum.com collects discussion of AMD's 64-core, 128-thread Ryzen Threadripper 9980X workstation processor and how it compares with Intel's competing Xeon 678X. Supplied coverage centers on Phoronix workstation testing that measured simultaneous multithreading, finding aggregate gains of roughly 16% to 18% for AMD SMT and about 11% for Intel Hyper-Threading when the second hardware thread per core stays enabled. The practical takeaway for developers, render farms, and CPU-based AI or content-creation workstations is to leave SMT on unless a specific measured workload proves otherwise.

    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...
