Is it true Ryzen has higher input lag than Intel? Is there conclusive data to prove this?

[Digika]

First reviews are out, not seeing any latency test tho

[Niko]

YES, even now with Zen3 they have higher Core to Core latency

mind if you show some links for that?

Inter-ccd communication is still very slow. But honestly, the core to core latency within the ccd looks quite nice, so one ccd processors like the 5800x might not be too bad. Memory latency is still pretty bad compared to intel, lowest I saw was 48ns (aida).



Sources are all linked into the pictures.

Thank you very much
Gonna throw myself on reading

Yeah, Intel always was good on some genius trickery to minimize memory latency, especially when they increase cache size.
Here is hoping ZEN 4 will address it in 2021 since it should be new platform

Ryzen 5600X having ~63ns in AIDA64 with 3200 with Corsair CMW16GX4M2C3200C16 (16-18-18-36).
Measuring in mlc (even with newer 3.9) version I get worse result than on old 2600 Ryzen. Maybe it is not good tool to measure it on Ryzen.

Have you tried 3800 mhz or better (Zen 3 should be able to reach 4000 mhz)?

[dervu]

Seems like Try it option doesn't let me use my memory with anything more then 3200 (XMP).

can you post 5600X MLC screenshot for research info and aida screenshot aswell to compare. ty
