AMD Ryzen 7000 Series performs better with Spectre V2 Mitigations enabled
“As for why the Ryzen 7000 series performance is actually slower if disabling the Spectre V2 mitigations, that's likely something only AMD can effectively answer but presumably…”<p><i>Just ask!</i><p>Seriously. You can ask AMD. Maybe they won’t tell you, but <i>they might</i>. It might be really good info. Why not ask someone who is really knowledgeable about this stuff like a kernel developer who works on x86-64 or worked on the mitigations?<p>This is what I never understand about Phoronix. People link to them all the time but they run a bunch of benchmarks and then end on “there you go”. I’d like investigation into <i>why</i>. You won’t always get an answer but you should try.
