Just spent the better part of a day playing with a 3900XT and came to pretty much the same conclusion I came to with the 3700X and 3600 processors....

Turning off PBO and offsetting the vcore by -.0875V nets me low temps and benchmarks that are within 4 -5% of what I see when I lock all cores @ 4350.

I dunno... maybe I've been spoiled over the years, but pushing an OC for anything less than 10 - 15% improvements doesn't make sense to me.

I can run my 5600X at 4600 all core @ 1.225, like an Intel. I can boot into windows at 4900 and do some stuff.. But I cannot nail down anything between 4600 and 4900. I gave up and ran PBO + 200. But.. for the most part a solid 4600 is the better performer. My 3600XT couldn't overclock either. I could run it at 4500, but not 4600. At stock it was hitting 4475 on 3 and 4625 on the other 3, with a hard load @ 4300. No point in ocing these things really. Maybe IF and mems but that's abut it.

This was brought up on another site. Should make finding your PBO2 curves a tad easier.

5900x with -30 CO yields that range of improvement (12%), minframerates are higher as well for what single core boosts are achieved. Most wont really care about 5-10% in this day and age but gamers (under 4k res) and some various other groups will. I read up on the previous zen chips and apparently OCing those generations is a bit of a waste of time and yield minimal gains like the 1800x I had.

Only minor drawback is the heat/voltage running to the chip, apparently PBO2 has some beefy thermal tolerance as the power draw sometimes spikes thermals to 88-92c for a moment when hitting 5100mhz boosts even on a noctua d15
