7700x best choice for latency for right now (low c2c latency and usb cpu port)
Can anyone personally attest to CPU handled USB ports vs chipset handled USB ports? Purely from an input response perspective.
Not interested about speeds or anything technical, but rather the feel.
As I’m aware Intel don’t tend to do cpu handled usb ports any more whereas AMD do, so I’m wondering if it’s worth the comparison as a potential culprit for these issues.
From watching this guys gameplay, you can clearly see he doesn’t have the issue

im sure amd cpu usb more responce then all intel i have (z390/z490/z690/z790).
i had 5800x + unify x570s (cpu usb 2.0 port)
Interesting. I guess another way to check would be to ask whether or not PS4 native runs through a chipset or direct to cpu. As the issue was also present there. Any idea?
i think if ps4 have same weird behaivor that not usb, that is emi.

No. It's not EMI.
Do you know if PS4 runs through a chipset or direct to CPU?

I have 12900k and ddr4 4000 mhz cl14 rams.
Should i upgrade to 14700k/kf or 7800x3d?

Yeah, downgrade to 14700KF which will stop working after some time
Of course, NOPE. Wait for 9800X3D this year release, if you desperately need/want to upgrade, 12900K is not such an issue. 7800X3D is very tiny upgrade and 14th gen Intel is just a joke botched generation which gets malfunctional very often, avoid at any cost.

From experience, ps4 controllers (overclocked to 1000hz) feel horrid & slow on AMD systems. Every pro/cracked content creator that uses a DualShock 4 uses Intel. Although AMD may have more frames & on paper is better, they have a ton of bugs, inconsistencies & issues that affect in game performance; even with a ton of frames. I myself ran into issues aiming & winning fights on pc & I couldn’t figure it out until I did some deep diving & noticed patterns amongst my friends. We’re all on AMD & the best players were on an Xbox controller or Dualsense. Fortnite, apex & cod/warzone pros & content creators are 90% on intel despite what the on paper performance says; to narrow things down, any of them using a DualShock 4 is 100% on intel. Intel just has better chipset latency of atleast consistent performance for HID devices. AMD has a bug pertaining to DualShock 4 controllers only where usb ports that were cpu connected were faster than chipset. But the polling data shows a ton of spikes & jitters (this guy shows the input lag difference pointing to AMD & DualShock 4 users only:
https://youtu.be/82K3Pb0178g?si=KzaW65Zs4RHpiPdd). If you’re gonna be on AMD, only use a dualsense or Xbox controller, otherwise get Intel. This coming from someone with a 9800x3d & 5080. My next upgrade will likely be Intel since it’s ludicrous how most pros are on Intel despite what numbers & critics may say.

I sold my 7800X3D and switched to a 14700KF — and even though the FPS numbers are technically lower, the overall experience is much smoother. I didn’t want to start a new thread until I had something concrete, but after testing and comparing two motherboards (ASRock Z790 Nova and Gigabyte Z790 AORUS Elite AX), I’m increasingly convinced that this issue is caused by motherboard power delivery behavior — not CPU throttling, not BIOS bugs, but something happening within the VRM and how the board handles current reporting and loadlines. The ASRock Nova has a 20+1+1 VRM setup and costs significantly more in my country, but despite that, I couldn't get stable behavior out of it. I had constant downclocking that I couldn’t disable (because the board won’t let you run without Speed Shift and turbo simultaneously), RAM wouldn't hold CR1, and I had random FPS drops even on a tuned BIOS. The advertised “Lightning Gaming Ports” didn’t show any measurable difference either. Switching to the Gigabyte AORUS Elite AX (which has an 8+8 phase VRM with Renesas RAA229130 controller) made a noticeable difference in responsiveness and overall smoothness. It led me to dig deeper into the VRM configuration, and here’s what I found helped a lot: I set IA AC and DC Loadline to 1 mOhm, all three IA VR Current Thresholds to 512, IA VR Current Limit to unlimited, IMON Slope to 100, and IMON Offset to 100 with negative prefix (so -25A), which effectively reports to the CPU that it’s drawing less current than it actually is. I also changed the setting "VR Power Delivery Design" from AUTO to a fixed value based on the VRM controller (in my case Renesas RAA229130) and board layout. So far the system feels noticeably snappier and doesn’t exhibit the sluggish behavior I was chasing for weeks. Not saying this 100% solves everything, but the improvement is real and repeatable. Let me explain what this setup actually did: by reporting lower current (via IMON offset), I’ve effectively relaxed the internal current protection behavior, which combined with tight loadline (1 mOhm) prevents unnecessary vdroop, and avoids triggering unnecessary internal limits that slow the CPU down even if thermals and power limits are otherwise fine. It's not classic overclocking — more like VRM behavior tuning to remove artificial regulation. i will probably always choose intel over amd just because when it comes to tuning there is no limit, u cant really tune amd bios, its agesa locked.

can confirm every word you say, I have tried 3 motherboards, 3 RAMs, out of 9 possible combinations, only with the msi board which has a good vrm with g-skill RAM I can play without being distracted by technical problems
the fact that the built-in pbo optimization presets change sensitivity beyond belief drives me insane, I plan to switch to 14700k, I was baited raw by the performance of 7800x3d

i never go again to intel anymore after new cpu amd.
