Someone who bought into AM4 near the start would have seen gaming performance go up by over 100% over the lifetime of the platform but those buying into AM5 might only see a 10-20% gain depending on how Zen 6 goes at this point.
Good point, i never though about DDR6, that will requite a new platform for sure.
For me that just reinforces my theory about the Windows Scheduler.
MLID predicted it
MLID couldn’t predict the sun rising in the morning sky.
even talking to SMT thread on same core increased latency from 6-7ns to 15-16nsActually it looks like whatever AMD did its not just CCX to CCX latency affected, though that is the worst. A thread jumping between the CCXs has a latency penalty of 250% over Zen4, however the latency of a thread jumping from one core to another within the same CCX also has a latency increase of 40% compared to Zen4.
Meaning even single CCX Zen5 CPUs like the 9700x are suffering from higher latency between the cores. Can Windows fix that?
If it is an issue with Windows they can't really say so, last thing they want to do is pee off MS.It would be great if AMD can quickly clarify what has happened as the media is just running around trying to guess whats wrong
Latency doesn’t explain the hit and mis performance between tasks. Is it a memory flushing problem?
I’m tempted to buy a single and dual CCD chip and test. It could make me a YouTube tech journalist billionaire sensation, over night.
I actually think latency can explain all of itLatency doesn’t explain the hit and mis performance between tasks
