AMD to unveil Zen 4 CPUs at CES 2022

[Curlyriff]

Debauer said on one video that you can't remove socket backplate anymore. Coolers / blocks might need adjustments? Different screws, not sure.

Not sure but EK have said you can switch the backplate to make the new block usable on older systems so not sure if would be other direction.

Ok, Christ....

The Headline

"AMD are becoming Intel"

Because they are making you change the platform.
The AM4 platform is now 5 years old, so they are making you change it after 5 years, this is not at all like Intel who make you change it after 2 years.



For the 5950X AMD list the TDP at 105 watts, actual power consumption 120 watts
For the 12900K the TDP is listed at 125 watts, actual power consumption 240 watts

Measured at the EPS rail, Gamers Nexus.

Again, nothing at all like Intel and its Intel who are much further away from the real power consumption than AMD.

This is an example of what i'm talking about when i say tech journalists don't know what they are talking about, the only thing they are good for is creating click bait.

And some of us keep falling for it....

If you actually watch the video he makes a good point about the 7950X from AMDs slides being 47% faster than a 12900k at equal power usage but over 60% faster normally which would imply it's using more power than a 12900k.

 

[Joxeon]

They used DDR5 6000 CL30 for both

But AMD was using a 6950XT with smart access memory on for Zen 4

sneaky, well I dont need to upgrade for awhile sticking with 5900x unless i see some big bottlenecks with next gen gpu's

Analyse that for a minute, it suggests that the 7950X is pulling around 270 watts at full load, which is 40 watts higher than the AM5 socket limit and 100 watts over TDP.

It really doesn't take much to realise something is up with AMD's wording in how we would normally understand it, IE in how much power the 12900K actually consumes, AMD are probably thinking "the 12900K has a TDP of 125 watts, our CPU's pull about 170 watts" and with that they do the maths.
I will eat my Keyboard if its pulling 270 watts.
Think about it.

 

[humbug]

A tech journalist with an ounce of intelligence would have realised that ^^^

 

[g67575]

Guessing they used 4800mhz for Intel?

lol, you could find this stuff out, you know.

It's all AMDs own slides unless they are locking the 12900k at 125w.

They are, at least that's what i think.

 

[humbug]

Someone at AMD thinks Intel's TDP ratings are accurate. Which is hilarious.

I will point out that the power draw will likely be post 200W for the 170W Zen 4 chips humbug under full load, if you had actually watched the 5900X review from Gamers Nexus then you will see that silicon quality does have quite the affect on total power draw with AMD. Now its unlikely you will see that kind of load regularly but its certainly capable of pulling.

Here is the official AMD statement to tom's hardware

"AMD would like to issue a correction to the socket power and TDP limits of the upcoming AMD Socket AM5. AMD Socket AM5 supports up to a 170W TDP with a PPT up to 230W. TDP*1.35 is the standard calculation for TDP v. PPT for AMD sockets in the “Zen” era, and the new 170W TDP group is no exception (170*1.35=229.5).

"This new TDP group will enable considerably more compute performance for high core count CPUs in heavy compute workloads, which will sit alongside the 65W and 105W TDP groups that Ryzen is known for today. AMD takes great pride in providing the enthusiast community with transparent and forthright product capabilities, and we want to take this opportunity to apologize for our error and any subsequent confusion we may have caused on this topic." -- AMD Representative to Tom's Hardware (emphasis added)

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.

Hope that clears up the misunderstanding we had in the other post.

 

[haszek]

Design of socket is useless info if socket is designed for multiple years and future products with possibility of more cores/power draw. It doesn't mean it is for this gen.

 

[Andromeda1983]

AMD has since clarified that the 170W TDP will apply to Ryzen 7000 so the 230W PPT DOES mean for this generation. They are making the most of the headroom that the new socket allows with these new 170W chips.

Where? Even quote you gave was clarification to socket and not specific SKUs.


Edit
Right ok, I see this now.

 

[welshrat]

Well Zen 4 shaping up really nicely. Going to sit this one out as just aquired a 5900x but will most likely upgrade in 2024 or later 23 so it's good to see all very much on track.

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

Pump up the power

www.tomshardware.com

Tom's hardware does confirm from AMD that it does apply to the 7000 series of chips. So the 7950X and 7900X will have a 170W TDP with a PPT of 230W...

Edit: all good Haszek <3

It is worth noting you can always turn precision boost off.

Also eco mode for all historic Zen chips resulted a 65W mode. I wonder given the slides they will add a 105W mode.

Oh totally

 

[muon]

Oh totally

For people that are gonna complain about 230W.

It is high to be fair though, and probably way past any sensible efficiency range. I would personally turn it off. 170W is plenty for a few threads to still hit 5.7ghz.

I currently run a 5900X with a 170W PPT. I think its about the right point where you dont have to worry too much about cooling.
