so, since the BIOS works a bit better, i for the first time since i have this PC (2 years minimum) was in an experimental mood, and i put my best thanos face on and thought to myself "fine, i'll do it myself!"
i played around with destiny 2, and the options of core parking.
i run a dual monitor set up, cause i'm ADHD like that. i had firefox running with twitch, and a 4K video next to it in VLC on one screen, and destiny 2 on the main screen. i played all those strikes so many times, that yesterday, i dozed off whilst playing, and watching a video, and i woke up at the end of the strike, and it took us maybe a minute more than when i'm fully awake. i'm a multitask master.
so for starters windows with no aid besides gamebar and the new driver from AMD. reliable in changing the CCD. but doesn't allow for both to really be used. it throws everything on the gaming CCD once a game is on, and if it peaks, it throws things on the parked CCD, which caused stutters, mostly just one noticable one every minute give or take, depends on the amount of action on screen, annoying. pretty smooth tho, when it works.
now the new mainboard solution for CCD parking. when it works, it definitly feels the smoothest, but it sometimes forgets that there's also a game running, and without restarting the game, it stays on the none X3D CCD, dunno what causes it, sometimes in orbit (which is basiclly a hub area in some sense) which is sad, cause it somehow even managed to throw some of the workload of the none gaming tasks, on the CCD which is literally just idling in the system, which is what you'd expect the system to do. why else would you have a second CCD in the system, when one could be focused on only gaming, and the rest is on the CCD which is far better for tasks. that lax workload should be no issue at all, as destiny is not really that CPU bound, and i have a 4090, so it's moreso GPU bound, at 3440x1440p.
process lasso. feels the worst, after having tried the other solutions, but it can keep everything on the right CCD cause you can literally chose where what runs. it's not unplayable mind you, it's just, that the new mainboard CCD solution when it works, feels buttery smooth, with barely any frametime spikes, when it doesn't forget that you're playing a game. lasso even in heavy action scenes, stays the exact same with minimal frametime wobbles, whilst both other solutions, are making the gaming CCD spike too high with too many tasks which are not games, and throw parts of the game on the non gaming CCD, when you'd expect it to throw tasks on there.
i currently have an ingame build perfect for stressing thee system, which is triggering so many effects, that the CPU is starting to sweat with process lasso, but it continiously stays below 90 in usage, and uses all lanes. both other solutions sadly, often even have 1 or 2 gaming lanes asleep on the gaming CCD, and instead of utilizing those, suddenly throw things on the non gaming CCD. in ryzen master, there's also on both CCD a best and a second best lane, and those were sometimes the ones sleeping on the X3D CCD XD
conclusion. this double chip design is not it for AMD. they either need to put a scheduling chip which can handle two lanes simultaniously on this chip, with an AI solution or something to keep the schedules in lane (cause when it is scheduled correctly, not even pure graphics insanity can overwork it), or stop the cap, and release a real 9950X3D, where both CCDs are X3D.
as it is, it's a bit of a false advertisment, cause the whole chip is more of a work chip, cause that works well on it, with a second mode for gaming, but highly restricted.
why am i being so picky? cause my intel 8086k didn't have any of those issues. it could easily carry all that stuff, with destiny 2, without having even a noticable impact, besides of course, being far weaker and having generally lower overall FPS.
as for the wobble, i'd chalk that up to the lack of a real scheduling chip which can feed both CCDs correctly, and one CCD being bothered by the other. i never had a none X3D chip, so i can't really say if those issues exist on those, but problem here is, a reviewer is of course always gonna try to create the most favorable testing enviroment, and every bench you see in videos, is after a fresh boot, to see the max power of the system.
i didn't try turning off the CCD yet, but there's like 500 videos about it online, just not in my usecase, but i doubt it would be much diffrent if the tasks make it peak with scheduling multiple tasks at once. the main problem here is how it is scheduled, and probably how many lanes there are for simoultanious tasks on both CCDs and/or how they interact.
which solution will i go for? tough choice to make. if i could turn of the CCD without having to do it in BIOS, i'd go for that or the onboard mainboard scheduler. but, for now it's probably gonna stay lasso, until the next update, cause like with all things gaming, consitency is key, and the frametime wobble in lasso, is so consitent, that you grow accustome to it. but switching back to buttery smooth is hella jaring.
i know, it's a bit off topic, but it also is on topic as most ppl have been vocal about wanting changelogs, so i guess since ppl throw their overclock metrics on here, a bit of a dirty quick review, also has some validity to be here, when it comes to testing a new feature.
i don't know how deep the BIOS can even aid a usecase like mine, without a dedicated solution on the chip itself. all i know is, that intel has their chips and chiplets under better control in multitasking. AMD definitly has to put in some over time here. i was actually hoping that the new 9950X3D is gonna have a solution like mentioned on it, and not just a "we put the X3D under the chip for better termals" solution in it. they said they have exciting news, needing a bit less juice, and a bit better termals, is not even remotly exciting, cause games don't stress the CPU into peak temperatures anyway. for me, the termals with a decent 360 AIO from ASUS ryujin 2, never even go over 75C, and that is only when the CPU is like under real pressure, with a fanprofile on normal.
yadda yadda strix x670e-f, Aorus waterforce 4090, some g.skill ram 64GB, obviously a 7950X3D.
also wanted to say i'm glad that the BIOS is becoming fun now. my best friend is gonna be hella excited once i hand him the mainboard, as soon as i get my new one. he's also not even remotly as picky as i am, after 13 years now in the pro PC space. guess his birthday is gonna come a bit early this year.
