AMD in its architecture deep-dive Q&A session with the press, confirmed that the "Zen 5" and "Zen 5c" cores on the "Strix Point" silicon only feature 256-bit wide FPU data-paths, unlike the "Zen 5" cores in the "Granite Ridge" Ryzen 9000 desktop processors. "The Zen 5c used in Strix has a 256-bit data-path, and so does the Zen 5 used inside of Strix," said Mike Clark, AMD corporate fellow and chief architecture of the "Zen" CPU cores. "So there's no delta as you move back and forth [thread migration between the Zen 5 and Zen 5c complexes] in vector throughput," he added.
