To me basically Intel is dead after i9-9900KS, the efficiency doesn't make sense in full load.
Imagine my CPU core temp is @ 96-98'C even with my custom loop.
So i know AMD is the only way can go if i want something immediately.

Eh.. intel 10th and 11gen actually have a pretty big OC headroom and very fine tuning features which AMD lack with OCTVB(10th)ABT(11th) and MCE, provided you can tame 250W and up to 400W if you wanna go crazy and not use AVX offset. Those you see online especially gamer nexus are a bunch of noob just put the multiplier numbers and run those CPU close to 1.4V. Of course will seem very limited. This is why some OC Enthusiasts still prefer to play with intel at the moment because the platform has more things to touch and tweak.

for AMD yeah... it's pretty much plug and play and it will opportunistically extract its max performance out of the box automatically based on thermal and power limit... that's where the PBO2 and undervolting comes in

avx offset, per core overclocking, or even set a power limit... well pretty much undervolting. if you dont hold AMD back and let it unleash, it will also hit 200-300W easily.
kinda depends on how you view efficiency. intel is draw alot at max but average is low. AMD is draw lower at max but average is high.

like me, I set up my 10600K to 125W max as that was the limit to my 120mm aio do some optimization. Overall, it's much faster and much cooler than my Ryzen3600. my i5 gaming always below 60C while 3600 above 75C. (also due to AMD have higher power draw at low load situations like gaming)

Zen3 (or any Zen generations) cannot idle at 1ghz. The CPU will simply cease and BSOD. You can further lower clock down state by lowering the minimum CPU state in Windows power plan. But if you ask me, there really isn't that much of difference because the CPU will keep boosting to beyond 4ghz anyway the moment you do something on the desktop, even as much as opening a folder.

As for cold boot issue, you have 2 choices:
1) Flash to an older known working BIOS.
or
2) Tweak the LLC and voltages + RAM timings manually.

Zen 2 and 3 has great so far for me too. The kind of multi core perf that simply can't be had with Intel atm, yeah - few minor irritating issues here and there that plagues some users (touch wood I don't have them) outweighs it. I save time doing work and earn more with it to buy the next best thing, be it Intel or AMD.

This AGESA bios is something really missing in HW review everywhere. I always read HW review like Toms, TechpowerUp, Anandtech etc., but no one mentioned all the weakness but just end up with 'highly recommended' 'gold award'...So it give an impression to me AMD is 'perfect'. (me too native huh).

Regarding the cold boot issue, i'm not going to fix it as i will just left my rig to standby/sleep 24/7 without plug out AC will do. Or i can disable DOCP before i do so sometimes like away from home more than few days.
With that money, i should have go for Gigabyte B550/570 Aorus Master rather than this Asus crap if i'm not prejudice due to my misjudgment last week (i thought is 3rd time the same board failed me). I lost the front QC3 USB charge, back panel clear CMOS button, onboard reset button by changing from my Z390 Aorus Master to this Asus B550, those are quite useful/important features for me.

Anyway, is this cold boot issue widespread in AMD platform but not Asus alone? Changing motherboard is one of my thought last week, but scraped after further survey, basically left no choice and stuck with this, not worth it for such tiny cold boot issue.

Haha, I totally lost in RAM memory chip, and i don't think seller disclose the information (they don't even know maybe). So i just choose whatever capacity i want with reasonable speed (3200MHz is baseline).

My RAM stick just went for RMA yesterday and stuck with 32GB with me now, at the same time i just ordered 2 x 32GB GSkill Trident Z Neo 3600 due to my work nature need for electronics/CAD simulation, so min 64GB RAM is needed.

Sadly, idle power management is crap for Ryzen. Read starting from here.

https://forum.lowyat.net/topic/4192804/+7800

I don't know whether the cold boot is Asus limited or widespread as AMD platform, but solution for Asus is:
1. Run the speed 1 rank lower than rated XMP. 3600 -> 3200 etc..
2. Change the CL from rated to few clock lower. CL16 -> CL18

Both are HELL NO solution to me, is not end of the world by put my rig standby in full time rather than to sacrifice the RAM performance.

all i can say is, they are probably short handed on the inhouse implementation side aka the software. The hardware is all outsourced especially to TSMC that's why it is so damn high quality and good. So it's actually the software side is struggling to catch up to the hardware.... but the hardware is progressing way faster.

AMD idle 24/7 will draw a lot of power to your monthly bills siot

Hey, you finally appear...someone meantioned you on this idle management issue but i can't found anywhere, thanks.

Haha, nonono, what i mean is i won't turn OFF my AC plug 24/7 but just put in sleep.
The cold boot issue only occur after shutdown and AC switch OFF, no issue without doing that.

your coldboot is ram stability issue la tu.... better run some memtest and see. You will not want data to be corrupted on ram and then stored to disk. you can potentially brick your OS like this... or ruin your work files. Even more so if you gonna run 64GB..AMD memory controller is weak. Going 2X dual ranks will be a huge challenge. While single rank 32GB are sadly samsung C, micron RevB which AMD dont really cooperate well.

I didn't manual overclock my RAM at all, what i did was enable the XMP profile (Asus called DOCP) only without adjust any timing manually, not stable? I have use that RAM with my Intel rig for more than 1 year without any issue.

Just to be sure, many Asus user use their QVL RAM also facing the issue.

My idle power consumption right now.

XMP is not guaranteed to work. even if it's on the QVL, regardless of intel or AMD. (altho AMD is much more sensitive)

Haiz, so damn much constraint...will just sell it if really not working well. Hopefully Intel can bounce back anytime sooner. (I doubt so)

5 loops without issue. Or need more?

Try to find memtest pro and then run overnight to about 10passes.. those usually will take more than an hour for a single pass.

Depends on your usage. If you need alot of cpu cores, there's no competition. All the benefits far outweigh the setbacks as ben mentioned.

U didn't read the OCN forums and Reddit where it matter most.
All the reviews are totally gold on Ryzens for those popular review sites. They didn't tell users the potential issues & problems especially with zen 3.
Nowadays review sites are impartial, what matters to them is which product gives the highest output/performance instead of doing a overall/balance review on all aspects that any users should be concerned about.

I mentioned this issue before.
Strange that Zen 2 3950X idle power consumption (including SOC and CPU, see below) is way better than Zen 3 5950X (Same as your results of 25 - 30 watts)

This is mine with undervolt, otherwise it could be higher.
