intel x amd inpug lag.

I went from i5 3330 to a 5700x3d and oddly enough my i5 3330 seemed more responsive than the 5700x3d. I couldn't stand it and had to buy a 12600k to see if it was really a difference in platforms or the old processors were more responsive due to having less RAM latency, less bios settings, etc... and no, the 12600k is much better in terms of latency and mouse sensation. the 5700x3d was less responsive and the mouse seemed a bit floaty to me, now my performance has improved 100% after having an intel ddr5 kit.

To get great low lag on AMD systems (lower IPC numbers, better low-thread-count game performance), try temporarily turning off half or three-quarters of the cores temporarily for games that don't require many threads. You can also use utilities that temporarily turn off cores when specific software launches (favourite esports software). This can get AMD as performant as Intel for certain critical lag things.

The "temporarily disable excess cores for certain games" advice is hugely popular even in Google

The latency between half of the cores on an AMD CPU is usually horrible, so temporarily turning them off or configuring thread affinities for specific games -- can do big wonders in improving performance in certain games.

Also, don't forget chipset can add some latencies (e.g. very bad USB chipsets). Some chipset Ethernet/audio/etc produce lots of lags, so try external / PCIe methods, or even a PCIe USB3 card, to bypass any inferior chipset, if you've swapped motherboards.

There's some really odd tweaks that has worked for some of us
- Separate PCIe USB port card, to bypass crappy AMD motherboard chipset ports that easily get congested by more than one high-Hz device
- USB roulette (trying different USB ports for high-pollrate devices) or making sure 1-USB-chip-per-high-pollrate device
- Switching between vendor drivers and Microsoft drivers for audio
- Even weird fixes have occured such as
....Changing Ethernet adaptors (away from the chipset one)
....Using external USB-C "audio card" to bypass a chipsets' crappy laggy audio adaptor (NOTE: Can make things worse, see USB chip congestion)
- Etc.

Occasionally unorthodox fixes can fix floaty mouse problems quite well on AMD systems (etc). The sad reality is that there's more lag-crappy AMD motherboards than lag-crappy Intel motherboards (which happens too). The "weak link in chain" adage applies, and sometimes the AMD CPU is note quite fully to blame!

Please verify that your chipset isn't making things worse if temporarily disabling half of the cores on a massively-multicore CPU doesn't help. The reason is that the silicon for half of the cores are on the opposite edge of the chip than the other half, adding nanoseconds of latency. But figuratively, a million nanoseconds can build up to a millisecond if too much cross-core dependancies occur in critical loops, etc -- death by a thousand cuts.

Personally I use Intel but I acknowledge you have to do a bit more legwork to fix some lags on AMD systems, but it is (largely) fixable if you know what you're doing. And definitely don't cheap out on the motherboard, you want good USB latency for concurrent high-Hz keyboard and high-Hz mouse. Some crappy chipsets can't do both simultaneously and you have to offload one of two to a PCIe USB port on an expansion card.

And prepared to purchase $20 hardware from Amazon or other store to bypass inferior chipset stuff (like a specific chipset's inefficient audio adaptor, or inefficient/limited USB). I run into this way more often on AMD motherboards than Intel motherboards, and many incorrectly blame the AMD CPU (even after failing to fix things by temporarily turning off half of its cores).

connect mouse to cpu usb (only mouse in cpu, another in chipset).
3dx cpu have less responce then usual amd cpu.
try put 5600x or 5700x/5800x (b2) and try it.
