Ryzen vs Intel Input Lag/Latency

[boxszs]

Are there any up-to-date benchmarks on this? I'm looking to build a new computer and I was thinking about getting the new X3D chips in the Ryzen 7000 series.

There are a bunch of comparisons between Intel vs Ryzen Setups that have identical performance. It showed no Difference at all. On paper, if you compare identical performing Ryzen vs Intel Cpus, Ryzen tend to have around 10 Nano Seconds more lag. That doesnt affect your performance at all.

I have two systems. One AMD and one Intel.
The Intel one surely is more responsive with less DPC latency than AMD.
I have the 5950x and 13900k.

Well, it would be good to know whats your AMD parts in the AMD system.

32gb DDR4 3600

This is on Intel.
This is the lowest i can go. I cant find any tweaks that will help the latency to go lower.
On AMD i was on 0.52-0.53 avg.

These results are self explaining given the fact your AMD System cant keep up performance wise with your intel System, due to better and more expensive CPU and better ram!

Its a well-known fact that AMD systems have higher latency than Intel.
Even by disabling one CCX on the 5950X i couldnt bring down the dpc latency like Intel on AMD.

If you care about testing input latency and low price go for AMD… If you want gaming CPU there is only Intel….
I bench CPU like gamer not synthetic testing measure ns (its kinda nonsense)

I’ve had the following systems:
- 9900k + 3070 with 3200cl16 (basic XMP)
- 5900x + 3080ti with 3600cl14-14-14-28 bdie
- 13700k + 3080ti with 3800c14-15-15-30 (same ram as above)

The Intel based systems feel snappier and have more stable frame rates in game, especially at 1080p. I noticed the 5900x produced higher highs but lower lows. I experienced more stutters and just overall stability issues on AMD. Something to do with the chiplet architect I’m sure.

I actually swapped my mobo and cpu to the i7 and kept everything else the same. If you’ve only ever used ryzen you might not know the difference.

This was another tech subject in which I fell for the techtuber jargon and general consensus that AMD is just as good as intel now. Similar to the IPS vs TN debate.

If you want the fastest stuff with most stability and driver support, and like overclocking and tinkering, go Intel + nvidia.

Also if you’re on ryzen, don’t use PBO outside of games like Valorant or Csgo. Games that require multiple cores/threads benefit from a manual static clock speed. Once I disabled PBO and ran a static clock of like 4.6 all core, I noticed my games ran a bit smoother with less stutters.
