SMT Proves Very Advantageous For AMD Ryzen AI MAX Strix Halo Performance
While Intel opted against implementing Hyper Threading for their latest Arrow Lake and Lunar Lake processors, Simultaneous Multi-Threading (SMT) still proves very effective on the AMD side.
Even though the top-end AMD Ryzen AI MAX " Strix Halo" SoCs provide 16 Zen 5 cores, the presence of SMT for 32 threads still proves worthwhile from both a performance and power efficiency perspective. Curious about the performance and power efficiency impact, I ran some benchmarks of SMT enabled/disabled on the HP ZBook Ultra G1a with the AMD Ryzen AI MAX+ PRO 395 under Ubuntu Linux. Beyond laptops and mini PCs, even testing on high core count AMD EPYC 9005 CPUs show SMT being a significant win.
