Linux recognizes Starfire’s memory-controller ID. Intel’s newer brochure lists up to 80 total TOPS, while radiation characterization remains explicitly in progress.

The correction assigns Family 1Ah models D0-D7 to Zen 5. Family/model classification is distinct from marketing names, shipping products and measured performance.
