AMD Ryzen 7000 Undervolting Yields Great Results with Temperatures

[Minus Infinity]

This highlights why I won't go near a new MB and cpu until bios and fw is sorted and preferably we are on Rev 2 versions of the MB. Luckily I have no need to update until well into next year. I just hope it's all fully sorted before v-cache models appear. But these voltages and temps are crazy, hard to believe there's not issues with the setup/fw etc.

Im surprised so many veteran users still act like this is something new.
Power optimizations of this factor or close to it were available in CPUs pretty much since X58 era.

I would recommend anyone with some minimum knowledge and appreciation for quiet and power savings to power optimize their parts. You do it once, and just save the profiles.

AIDA64 ain't exactly a stress test that requires the most stability.

 

[JustBenching]

Ryzen dont either.

If you don't like the fTPM bug fixed, or the usb disconnects fixed, or the botched sata speeds sure, you don't need to bios update

For using 125W?
I'm not sure you thought that one through.

I thought the 7950x runs at 240w, didn't know it's 125w. That's great news. Any source?

Looks like the same old f$%^up as with some older FM2/FM2+ boards. Due to a stupid mistake in firmware some boards were running my Athlon 860K above 1.5V all the time, sometimes as high as 1.65V.
That poor little ting was idling at 60-70C.

Guess you didn't think your reply through either, typical Mussels

Not really, every CPU in existence acts like that. High stock voltage is to cover every single case, some CPU's wont have the best silicon quality.

It is the same with alderlake, you could undervolt it to drop wattage by as much as 70w in CBR23.

Undervolting is when the applied voltage is lower than the one preprogrammed into the CPU. If the motherboard is using more voltage than it should at default settings (which can very easily happen, also on Intel motherboards), then it's just setting back voltages down from their initial overvolted conditions, not undervolting.

I never see any indication that such check is done in CPU reviews, by the way.

Q: Why are power levels going up when chip features sizes are going down, I would have thought that less electrons/power would be needed to do the work on smaller transistors?

Unless he runs something that measures performance, that is pretty much useless. He might be gimping his performance with that undervolt by clock stretching

Because Intel and Nvidia are losing the performance race, so they push the power up to get ~10%. Actually if you undervolt the current and the next gen hardware you will get impressive performance/watt, but the stock settings are never the best nor for high performance, cause you can get much better result with less watts with manual OC, nor for efficiency

Wait what? Didn't AMD basically double the power consumption of zen 4 compared to zen 3? WTF are you talking about? The now old and outdated 12600k beats the fresh not yet released 7600x by quite a wide margin at similar power consumption. So again, wtf are you talking about?

Agree with you, but a 12600k is not outdated is it? Still a great CPU.

No, power consumption and TDP are not the same. They raised the TDP, but it doesn't mean the power usage will double.
They also raised the base clock, which would Indeed result in higher base power usage, but we don't know by how much.

Sure, but it was already middle of the pack when it came out, and now both companies have come up with newer products. What I meant to say is, it should be outdated - yet here it is beating the newest mid range CPU from team red, and finally enough not by a small margin

But the leaks are suggesting we are looking at double the power consumption right? The 7600x has shown to be running at 125-130w at stock settings

Doing what though? Power consumption isn't static on any CPU, so that something can peak at a certain Wattage, means very little.
Not trying to defend AMD here, but at the same time, we're going to have to wait and see how things play out.

 

[JustBenching]

Doing what though?

Τhe same thing that the 5600x was doing at almost half the wattage?

Sure we have to wait for reviews, im saying the way it looks like now, the power consumption has gone up considerably on amd to compete with intel. Yet they even failed at that, seeing how even with that increased power levels, the R5 can't keep up with last years i5, and this years 13600k is going to be beating even the 7700x. Calling them R5 and R7 is hugely misleading, the 300$ 7600x should be called an R3 since it will be basically competing with the 120$ 13100 or something

Let's wait and see. It's still early days and AMD still has a fair amount of AGESA/UEFI issues to fix. It won't be as bad as when X570 launched, but I would wait a few months before jumping onboard so the remaining bugs get fixed first.

Funny how you talk like it already is released and tested. But double consumption compared to 5600x? Wanna bet, cause 125w will be achieved only with AVX512 and it looks like you are not aware that 5600x is using >80w with stock settings, not 65w

Funny how YOU started talking about unreleased and untested products and now you are calling me out for doing the same thing.

Anyways, you said intel is increasing power consunption cause it cant compete with amd, yet its a fact that zen 4 power consumption has gone up cause amd cant even compete with alderlake (both the r5 and the r7 lose in mt compared to last years i5 and i7). And yet its going to have to compete with Raptor Lake. So the question is, why are you lying?

Unlike you, I at least have an idea of how things are and I'm not talking complete nonsense like how the new 7600x will be 30% faster than 5600x with double power consumption.
Also, AMD is increasing the power consumption because intel is doing it. 13900k has higer power consumption and this is fact, higher frequency with another 8 little cores won't make this cpu less hungry than 12900k. And now when we judge cpu only by leaks, 13900khas PL4 420W, just double over 12900k
Are you starting to understand what nonsense you are talking or are you a lost cause?

The 12600k beats the crap out of the 7600x in mt workloads at similar power levels. What the heck are you talking about? That's the ALDERLAKE i5. I don't know why im trying to have a reasonable discussion with the amd fanbase, ***k it man.

You can't win that fight on TPU its about 85-15% in AMD users favour.

 

[DeathtoGnomes]

Reminds me of a certain unpopular AMD video card that had pretty much the same performance when it was UV'd.

Strange how every intel troll already saw the review of Zen4.
