need help understanding power draw of 5950x please

[inquisitor1]

I love TPU graphs for reviews but a bit confused

AMD Ryzen 9 5950X Review

Ryzen 9 5950X is AMD's flagship 16-core, 32-thread monster. It offers outstanding application performance, your productivity tasks will complete faster than before. Thanks to the Zen 3 IPC advantage, it also excels in gaming, even winning against Intel's Core i9-10900K.

first chart idle oc/stock is the same -all good.

2nd chart single thread. how is OC pulling less watts then stock?

3rd vs the 4th is confusing multi thread vs stress test which has it as stock 180 vs 194 and how in the 4th chart does OC use less watts

and in the 5th chart how is gaming more stressing (much larger power draw) as 2x the amount drawn vs a STRESS test? and also in that 5th gaming chart OC uses less watts?

how is gaming when the dynamics change is far far higher vs a stress test which pushes the cpu to its max to stress it. why call it a stress test if it isnt stressing it which is evident of power draw being half and how is OC less of a power draw then stock. its just confusing

I see there is stock to 4.9 and oc to 4.5 yet in some charts 4.5 uses more power then stock 4.9

very confusing. what im trying to understand is how much max power the cpu uses and for what tasks? it says whole system but shame it isnt showing just the cpu.

im sure im reading it wrong

ST - the "OC" is just a flat static OC. ST freq and ST Vcore will be far lower than what a single core alone is allowed to draw and hit under boost algorithm, hence power will be a bit lower (not drastically so, because all chiplets suffer x flat penalty of package power at all loads.

MT - stock Fmax for 5950X is 5050MHz, there is no chance in hell it will hit anywhere even near that with stock power limit (142W) on any meaningful (ie. not memtesting) all-core workload. You need way more power to work with in order to bring up the all-core freq. Chances are stock freq will land closer to 4.0GHz. Hence 4.5 static OC running all-core will draw far more power than out of the box "5050MHz", since it's just not even close to that speed in all-core.

Gaming - I think you missed the fact that the power graphs are whole system power from the wall, not CPU package power.

 

[inquisitor1]

how much power draw can I expect from the 5950x at its most with it working at 100% load? 250w?

 

[Toothless]

At stock, 140w-ish. With PBO on and all that tuning done it can do 220-240w.

Source: I have one.

fantastic! thanks for the info

You might consider investing in a good UPS with AVR or a kill-a-watt meter. The better UPS typically have an LCD status display and (with an interconnecting cable) software that lets you monitor, among other things, the power demands on the UPS. You can then experiment with different hardware configurations and tasks to see how it effects the power demand.

A kill-a-watt meter is nice to have too and lets you see what you are demanding from the wall outlet.

I would never install any software from a ups. investing in ups is not priority now at all. bought too many things lately and still needing to buy gpu. I am looking for a surge protector. that monitor looks useful

 

[Ruru]

Semi-offtopic, but how far a 5950X boosts with PBO +200? My 5800X goes up to 5.05 and I'm pretty sure that 5950X reaches higher clocks.

 

[freeagent]

I can do 260w with my 5900X with PBO enabled. So If I were to get my hands on one I would expect at least 280w with my tune.

 

[Bill_Bright]

Why not? Both APC and Cyberpower provide great little and unobtrusive programs that allow users to monitor and control their UPS directly through Windows. Very nice. No doubt other UPS makers have similar programs. So does Linux.

I am looking for a surge protector.

Well, it is your money, however understand surge and spike protectors are little more than fancy and expensive extension cords as they do absolutely nothing for low voltage events like dips (opposite of spikes), sags (opposite of surges) or brownouts (long duration sags) - any of which can cause a computer to crash, possibly corrupting your drive(s).

And for excessive surges and spikes, they simply cut power (“IF” working properly), crashing your computer - never good.

When (not "if" but "when") the surge and spike protector wears out (it is recommended surge and spike protectors be replaced every 2 years) or is damaged, they typically provide little to no protection at all.

Also understand backup power during a full power outage is just a minor, bonus feature of a "good" UPS with AVR. It is the AVR (automatic voltage regulation) that makes a "good" UPS with AVR so valuable and important, protecting your connected devices from all sorts of destructive power anomalies.

That said, should there be a full power outage, and if you have your network gear protected by the UPS (recommended), your wireless network can stay alive during a full power outage so you can still connect and communicate with the outside world via wifi with your other wireless devices, like tablets, notebooks and even cell phones in wifi mode.

Funny that I don't personally know anyone with an UPS or a surge protector. Is that more an US thing?

I am in Canada and I use a decent surge protector on my boys computer, and I use a nice line conditioner on mine. Right now I see 111v, but it can go to 118 and down to like 106 or so. I can see when everyone in the neighborhood has their heat or air on lol.

Power fluctuates a bit here, not bad in this part of town though.

havent tried as I havent received. but I still have a pos mb so not sure what it will do. right now just a 5600x in there. well see. have you had snow in Finland already?

I guess with my board, the CPU is the limiting factor what comes to boosting. Yeah, though the snow has melted few times, but I guess this one is staying

It should hit 5250MHz, my 5900X hits 5150, yours hits 5050.. dammit I wish I had some cash lol.

mostly in extreme cold or hot conditions (when everyone is overloading the syustem with AC units) we have outages. many times in the summer. its not bad going out, but when it tries to come back up is the problem. many times, it comes up and goes out multiple times right after each other and thats when things can be zapped. I think I saw a "soft" style power strip?

can you please show me a line conditioner you are talking about. I only know about these power strips that have surge protecion. not sure how good they are.

Its old, but still works

Oh yes. Here in the civilized world we don't really need those things, but in the land of Nascar and Pro Wrestling the only thing you can trust is yourself, God, and This Name-Brand Surge Protector.

(they don't have outages more than we do I gather, or a much worse power network, but yeah it is definitely a cultural thing)

They may be more popular here, but it is not because they are more needed here. "Dirty" power is everywhere and IMO, every computer should be protected by a "good" UPS with AVR.

I think many in Europe don't believe they need that sort of protection because much, if not most of their infrastructure was rebuilt after WWII. But that is not true. Even in regions with a stable grid, destructive anomalies can come off the grid. And such destructive anomalies can even originate from within the home from faulty devices on the circuit - like a faulty microwave oven or $15 1500W hair dryer made in some back wood factory in China with parts from their sister factory up river.

Again, a "good" UPS is not about providing backup power during an outage. It is the AVR that makes them most worthwhile. I live in Tornado Alley, notorious for extreme weather and unstable power and looking at my UPS logs for the last 6 months, I see my UPS has provided backup power for a total of 71 minutes. And I can tell you that about 65 of those minutes was during one single outage in July. That storm included a hail storm that destroyed my roof and actually my power was out for 4 long, hot days. - but that's for a different discussion.

The logs also tell me my UPS "Intervened" 9 times during that period. That means there were 8 other significant "events" causing the UPS step in with backup power for a total of 6 minutes.

So it you discount the one 65 minute outage, that is just 6 minutes my system was on battery out of 6 months. The rest of the time, it was all about the AVR providing 24/7 protection. And FTR, there are ~259,200 minutes in 6 months.

Anyway, this thread is not about UPS or storms or dirty power.

why what would you get, your system is sensational. I wish on me. if I only gamed Id get the same cpu as you and before the x3d came out, id probably get the 5800x. I only want to have it for video editing and some gaming. no complaints on the 5600x. its pretty fast for me. considering I came from fx8320 and i7 6700 (which is also pretty quick for image editing)

I have never splurged on pc hardware. first time. weird. I want something, then get it and then I dont care that I even have it.

Oh yes. Here in the civilized world we don't really need those things, but in the land of Nascar and Pro Wrestling the only thing you can trust is yourself, God, and This Name-Brand Surge Protector.

During the time I owned my 5950X, I've never seen it exceed 200 W. It's usually 180 W full load, with the usual high idle from the IOD (~15-20 W) being unable to power down in the Matisse and Vermeer CPU designs.

I would consider a range between 180 to 250 W acceptable depending on clock, voltage, curve optimizer settings and your particular sample's quality. Also depends on how far will your motherboard allow it to go; most B550 boards including the likes of the B550-E don't exactly have the highest of TDC/EDC caps, and this can affect the 5950X's maximum clock speed. More recently released 5900XT should be the same thing.

 

[freeagent]

no complaints on the 5600x.

Also, I have a 5600X as well. It gets some hate, but I think its still a good CPU.

It shouldn't, I have to use Linpack to get the big power numbers lol

Yeah, hence what I put in brackets. I don't know why it's a US thing specifically but it is. Well I do sort of know but that is like a three thousand word article. But yeah if you have problems you can get stuff that alleviate those problems.

Anyway, this thread is not about UPS or storms or dirty power.

It can be whatever we want it to be man. FTR you're correct in that more people should have power protection, but also FTR a lot of people don't need it, because in very short that is what regulations are for.
