AMD had a mixed show at Computex 2022 last week, but quickly, and very efficiently, controlled the situation with technical marketing director Robert Hallock extinguishing Internet fires with his Zen 4 fire extinguisher.
Lisa Su, CEO of AMD, came up with a marketing slide that said Zen 4 would have a higher “> 15%” IPC (clock instructions), while watching CPU clocks increase at maximum “5GHz +”. But then, an engineering sample of 16 Zen 4 cores running at more than 5.5 GHz (5520 MHz to be exact) was shown on Ghostwire: Tokyo.
But now we have Tom @ Moore’s Law is Dead with a great new and very long video (40 minutes) that covers it all. At around 11am, he talks about AMD and the work they have been doing to get ahead of leaks and crazy expectations, saying: “Apparently other filters have been saying that (CPI) will be above 25%, 30%, 40% CPI and it just won’t be that high. “
Tom continues: “So if AMD looks around and sees that some of these fake filters still have a lot of air time on websites … they don’t want people to be disappointed to say a single thread increase 20% to 30% higher on high-end SKUs, a single thread increase of 15% or more or higher on low-end SKUs … they want you to get excited because this is a big generation increase over generation “.
“AMD wants to reject the craziest performance suggestions because that’s something AMD suffers from some of these fake filters, generation after generation every year, that some people are always disappointed with AMD’s numbers … like when you they say “RDN3 will triple the performance” even though I tell you no and I tell you it’s not for a year … there are people who tell you these estimates … you’ll be disappointed when it doubles the performance and AMD wants to advance it, they simply over-corrected what was needed to set expectations. “
