News AMD Corrects Socket AM5 for Ryzen 7000 Power Specs: 230W Peak Power, 170W TDP

[Admin]

AMD has issued a correction for the power specifications for its AM5 socket that will house the company's upcoming 5nm Zen 4 'Raphael' Ryzen 7000 processors.

The days of P4-era space heaters are back!

What was the reply to me stating that AMD is reaching Intel-levels of high-end consumption again...

 

[-Fran-]

Goddang it AMD... So now the TDP is 170W, up from 105W on their higher end parts and the PPT has moved from 142W to 230W. I hope that is now clear? I wonder if they'll clarify this yet again at some other point, lol.

That is a massive increase in power consumption for an all-core workload. I wonder if the efficiency has suffered from it. AVX512 and the addition of the iGPU must be weighing heavily. It could also be a preparation for the future generations as well. Maybe Zen4, specifically, won't be using that much, but later ones will. Currently, an OC'ed 5950X can indeed reach over 200W in some all-core workloads and have very good performance, so I'd imagine this is a similar thing?

Regards.

I doubt that AMD wont release power efficient versions of their CPUs, if they don't then we can just make them efficient through BIOS settings if that is a primary concern.

If that's 16 cores @ 5.5ghz using 230watts.....

 

[Co BIY]

Style wise the heat spreaders look good.

Like they are trying to restrain the beast beneath.

 

[JamesJones44]

I guess 5 Ghz is the new 4 Ghz from the NetBurst days. Seems like if you cross that magic number you're at very high TDP loads like you did back in the NetBurst days.

That's really the case with any CPU, you can always under volt. The question is, will you be able to do it on all chipsets or just top end.

This now also probably means that 7950X has B or C grade silicon, just like 5900X, that's such a shame

Tell me about it, my 5900x only hits 5150ghz!

 

[daworstplaya]

Oooooor this could just be because they added the AI (avx 512) and iGPU to the CPU and it needs additional juice to power those.

I'm hoping that the 230W peak number is really a peak number. Like, something that we won't see outside of Prime95 w/AVX.
I'm okay with 230W if that really is the max, with the memory controller running at full supported speeds. I won't be okay with these new chips getting to 230W regularly with standard workloads or games.

We'll see, I guess.

I doubt it is. When running e.g. cinebench my PBOd 5950x looks like this :

So all that needs to be done is compare AMD overclocked with Intel overclocked - for comparing something apple-ish to apple-ish, instead of one stock all defaults and the other one full throttle no limits.

That's where I'm hoping AMD sticks to the 230W package power maximum.
We already know that the 5950x's TDP is laughably low. But it seems that AMD is 'making corrections' here, hopefully to avoid the issues that both AMD and Intel have suffered in the past with publishing too low TDP numbers without explaining the limitations of the number they gave.

 

[alceryes]

Nope.
Neither is acceptable.

Well, the PPT for my x570 AM4 board is 142 watts (as per AMDs standard), yet I've had peaks of 240+ watts with 210+ sustainable. With AM5 I assume there will be 300+ watts available on the higher end motherboards with sufficient cooling.

Ouch. Were those peaks during CPU benches/tests? Do you see 210W while gaming, for instance? I'm actually okay with the 230W peak when benchmarked. It's the average, everyday that I don't want to see another 100W increase in.
I may pick up a good 1000W PSU over the summer if I see a good sale - I plan to move from my aging Z370 when Zen 4 comes out.

The PSU market may be stretched a bit thin come end of the year.

 

[SunMaster]

210 sustained, i.e. it stays at 210 during the entire test. But very few programs use power as those tests, so it's not really an issue (for me).

 

[alceryes]

I'd love to know what the max package power was for that Zen 4 16-core hitting between 5.2 and 5.5GHz across most cores, during the Computex demo.

"AMD's statement doesn't specifically call out the Ryzen 7000 series, but those processors will drop into the AM5 socket, so it's fair to assume that we will see 170W versions"

No it isn't fair to assume that. It's not outside the realm of possibility, but it's not so likely as to warrant assumption.

"the TDP value basically mirrors power consumption when all of the processor's cores are under load and not in a boosted state — i.e., running at base frequency"

This is wrong. Badly wrong.

No it isn't fair to assume that. It's not outside the realm of possibility, but it's not so likely as to warrant assumption.

I think it's entirely fair to assume and also very logical that we'll (eventually) get 170 watt version CPUs for the 170 watt TDP AM5 socket, as we've had 105 watt version CPUs for the 105 watt TDP AM4 socket. Why on earth would we not get that?

 

[kerberos_20]

am4 was limited by wattage...my first r5 1600x was eating 180watts on all core overclock
