Hi - regarding consoles - both playstation and xbox variants use and have always used AMD cpu and gpu's (as far as I know - latest ones at least for sure). Regarding stutter and that goes for all games - there is a reason ! Could be gpu stutter, could be cpu stutter - you need to figure out which one is stuttering. You cannot just assume it is the gpu - you need to verify this. Most often with dx 12 titles you have cpu stutter because of the way it works and the way it builds up the shaders in cache. Could be mismatch between what gpu render and what cpu render - they need to be at same pace here otherwise one will pause and you get stutter. Often you need cpu to render ahead if you have very powerfull gpu vs slower cpu. Try to cap frames to something like 120 and see how it runs.
Do you have gsync or freesync monitor ?
Did you disable ULPS (registry or use msi afterburner) ?
Did you raise min. clock to 100 / 200 mhz below max clock in the performance section / custom ?
Do you use one of the presets in game section - like esports or game ?
Anti lag on vs off - I have mixed results here depending on the game. If gpu is at 99% = maxed out - it make sense to have it on - if not - often set it to off make better result.
Do not use enhanced sync - I have freesync and on my end it is not good - but read about others here it works fine - try on or off.
I have warzone and I have zero stutters and also have a 6900 xt and freesync monitor and a 3800 x cpu.
I will admit I did have problems from start - but that was before I made a DDU of geforce drivers. I also use parkcontrol and lasso from bitsum and also the ISLC from Wagnardsoft (this one fixed my stuttering in BF 2042) - so had nothing to do with driver from AMD !
I also use game mod = on in windows
Again there is a reason for stuttering !
