Where are you getting this info btw?
Quite a few threads on reddit reporting such issues
https://www.reddit.com/r/PS5/comments/jtswtf/demons_souls_graphical_glitch/https://www.reddit.com/r/playstation/comments/jtlhar/need_help_setting_up_an_rma_for_my_defective_ps5/https://www.reddit.com/r/PS5/comments/jtbunk/ps5_overheating/https://www.reddit.com/r/playstation/comments/jtblcx/ps5_issues_visual_artifacts/The PS5 GPU runs on very aggressive yet variable clocks:
It tops out at 2.23GHz (or 2230mhz) for demanding titles.
For comparison, my Aorus RTX 2070 Super runs at 1905 mhz (+140mhz compared to the ~1770 mhz base model) and that's the highest out of the box vendor overclock, in fact it was assumed a typo when they announced it.
MSI's Gaming X version for example runs at only 1800mhz (30mhz).
The Radeon 5700XT runs at 1905mhz and a 'stable' yet agressive overclock is considered to be 2005mhz (+100 mhz is usually the norm if you have no guarantee that you have a quality chip that works beyond the advertised clockspeed).
However in some games that 100mhz overclock means up to a 10fps difference so Sony taking a risk with agressive clocks brings PS5 very close to Xbox Series X level (as Digital Foundry has shown) and their cooling solution can easily handle it (PS5 doesn't run that hot).
The Xbox Series X GPU only runs at 1825 mhz so the PS5 GPU runs an impressive 405mhz faster on what is basically the same architecture with cut down CU's (I believe it's 36(PS5) vs 52(XSX)).
However, it will lead to lower yields and more hardware defects as not every chip will be able to hit that number without issue.
Not to mention if issues are introduced on the assembly line like poorly applied thermal paste or a heat sink not properly installed it'll be noticeable sooner.
Which is why shortages of the new 6000-series GPU are also expected for the higher end models, considering AMD has moved to very high clock speeds to 'brute force' their way out of the performance difference with Nvidia.
The 6900XT will run at a boost clock of 2250mhz but that's a $999 GPU. The cheaper 6800 will run at 'only' 2105mhz.
In time their yields will get better but hence the expectation that shortages of high-end 7nm chips (Zen 3, RDNA2, PS5/XSX) will remain for the first half of 2020.
You're just not getting very good yields for a few months with these aggressive clocks but AMD doesn't mind because at 7nm they have a much bigger production volume and they can just build up stock for their 'budget' outings faster.
The Ryzen 5600X for example is easy for them to resupply considering they can use faulty 5800X/5900X//5950X chips. They're probably sitting on a stack of Ryzen 5600's already.
Oh and yesterday I read that Nvidia might adapt to TSMC 7nm processes as well so they're no longer tied to the 8nm Samsung node they're using now (to fix the 3000-series supply issues).
And that would mean all high-end in demand chips(PS5,XSX,ZEN2+,ZEN3,RDNA2/Radeon 6000,RTX3000) are sourced from TSMC's 7nm process.
