Yes ryzen tends to semi idle at much higher voltage than it loads. The argument behind it was to be able to allow it to boost on demand very quickly from a sleep state and not suffer instability or crashing. While at high loads, the cpu can lock into fix frequency so it can drop into a lower voltage and sustain at the voltage efficiency because it is no longer boosting up and down.

Hi All,

Currently i'm using 2700x with msi x570 gaming plus, previously my x470 gaming pro carbon was spoilt and send for RMA during MCO period, hence I have to buy x570 in order to continue to use with 2700x during mco.

Since now I got an extra M/B, was thinking to upgrade 5800x and sell off my 2700x bundle with x470.

Is it worth to upgrade 5800x now? I found lazada seller selling around 2299 now although slightly higher than srp.

Also understand 5000 series is the last gen for AM4 socket, so after upgrade this would be last me for another 3 yrs I guess.

GPU has more cores and faster than CPU, most expensive instruction are running on GPU, at higher resolution are GPU bound.
hence, games and mining are running on GPU, even your browser already utilize your GPU more than CPU now, because of ever increasingly complex web content.

Directx 12 and Vulkan made a lot of change to ensure low driver overhead, more draw call.
CPU wont be fully utilized by games, it will just need to be fast enough to pass the commands to GPU and run the games codes that are still in x86 instructions.

Welp, design choice, limitation of the game engine, optimization too expensive, deadline constrain etc, thus the cost are passed down to end user, us.
Game developer decided to stick with D3D12 because they already familiar with it, making new engine or integrate new stuff like DXR will save them a lot of time, result in shorter development time,
unless the team are really expert and decided to use alternative like Vulkan, people who played game with vulkan (Bethesha Id Tech 6)enabled will know you can just crank the graphic quality preset to highest level and your gpu still can take it like a champ.

You can even offloading the AI to cloud compute, Azure cloud, like the Titanfall and the sequel, resulted in less strain on end user system.

with the ever expensive hardware and scalper practice, Geforce now and Stadia starting to make more sense now lol

It is, but just like renior... got easy lubang to get it.

Nowadays I only use Microsoft Edge and Winamp when not doing anything else. Every app you add makes it harder to go low power mode. Ryzen has poor idle power management.

just to let you know, if you don't mind waiting till May/June, 5600x back on Amazon preorder for $350 including import/shipping.

If you getting full set, GPU is not a problem. More like 11400F and 10700/10700K/11700F kinda killed 5600x sales. No point getting 5600x when there's cheaper and same/faster intels. While 5800x is still abit too expensive at more than 10900k's current price and yet slower.

AMD has to at least slash RM300 to compete... which i hope they do

Stocks are ok in malaysia too. Just the msrp is not. Even in US it is sold around 400 USD on amazon I also just checked taobao... 1.3k is bundle prices. Alacarte still around 1.4-1.5k and it's subjected to SST when it arrives... so not much cheaper than buying locally.

Yup this B550 would work great even with a 5950X, I'd reckon. Was wondering if trading down for a B450 board is worth saving a few hundred bucks, since this is a budget build. Guess I'll stick to it.

Hmm.....then I shall stick with AMD own power plan for Zen2.
On the other hand, today someone at OCN posted :

Wonder how true is this?

Contrary to most recommendation around internet, the Star and Circle cores voltage cannot be set too low. Reason = boost frequency. High frequency = more voltage.
When you use curve optimizer to set negative curve too much, the moment Windows schedules a thread to that "preferred" core and it boost without getting sufficient voltage, it will result in either blue screen or some sort of weird error. OCCT software can be used to test it immediately.  On the other hand, this "preferred" core can downvolted a lot when idling without crashing whole system, assuming if you want to limit your max boost frequency in first place.

By the way, insufficient voltage for cpu cores during idling (or light work) tend to result in random reboot. I found the best way to trigger "idling" reboot due to too much negative curve optimizer is to scroll down reddit post non-stop. Now, most posts at internet suggest setting the most negative curve for non-preferred cores or bad cores, but my testing on 5600x(B550Tomahawk) and 5950x(X570AorusMaster) disagree. The non-preferred core tends to cause system reboot without bluescreen with too much negative curve when idling.
The trick to set NEGATIVE -30 on non-preferred cores is to set "extreme LLC" or highest LLC level at UEFI.
Unfortunately.....setting a high LLC can result in .....google yourself.

Wait.....you undervolt at Vcore main section? 
Wouldn't that result in clock streching and reduced performance? Read more here

Remember to disable Asus PBO fmax Enhancer
https://www.reddit.com/r/Amd/comments/jtpv6...ring_with_5000/
I am not sure if fmax Enhancer also interfere with 3000 series.

What is the cooler you use? 

Well.....if that can't cool your 2700x, nothing will..

Possible Zen 3+ (with huge 3D stacked L3 cache) to fight Alder Lake?

I'm now attempting to enable PBO and undervolt with Curve Optimiser.

But when I set PBO limits to "Motherboard", I get these limits in Ryzen Master:
PPT: 720W
TDC: 420A
EDC: 215A

Mobo: B550 Aorus Pro AC

Don't those "limits" seem astronomically high???

mine pulak everything will be upsampled to 24bit because my DAC dont support CD format 16bit which is 99% of my audio collection. pretty worried the upsampling with bit stuffing will cause some sort of "colouring" to the audio stream
