AMD 3000 TR-32core Spotted

think the 32 core will stick to the current 32 core's 250w, if not lower. Zen 2 has already shown about 30% lower power draw and more performance on AM4 so no reason to go up, especially when the prime enemy, Intel bakery's W-3175X sits at 255w TDP (forget whether it's true or not for now, we're talking marketing).

I think the TDP will still be around that 250W as you say but Zen 2 has PPT value to allow shorter boosts that use much more power, that's where I think the 300W will come in but that's only if AMD target 4.1Ghz all core boost.

Aye, it might bear the name "voltage regulator", I'm only focused on the part on allowing the VRM to pump in higher voltage and less current for the same power input to the CPU and reduce stress on the VRM. We can talk about stuff like ripple suppression and transient response later, after the weaker boards stop melting down their capacitors.

At least for the 64 core even if you manage to half the current going through the board VRMs, I wouldn't expect that much, that's still what I estimate to be 240A. I think we already have X399 boards struggling to do 240A?

 

Spoiler

Rough working below:

240A = 480A / 2 = 600W / 1.25V

Using a more likely retail TDP of say 300W and a PPT of 380W that's still 152A half the VRM current, far more workable but doesn't really allow of OC. Maybe I'm just wrong about how much you can drop the VRM current by but I fear all that is going to do is move roughly 30W+ static heat load in to the CPU package and that'll have to be accounted for in not only cooling but product TDP.

We still have... those with heatsinks designed by a designer, not an engineer, sadly. At least now the Zenith Extreme (thx to fan hidden below the I/O shield) and MSI X399 boards before the Creation can do it.

 

152A is stupid easy, only the Asrock Phantom 6 might not do it easily (it is the cheapest X399 board,) and carries the VRM from their Z390 ITX board. I think it's exactly half that on the X299 OC Formula, with only 6 60A powerstages.

What about OC though? I agree 152A is easy but Zen just eats power under OC. Where does the problem point start for current boards, the not so good ones? 300A or closer to 400A?

linky to motherboard tier list

 

Tier C (250W) on X399 boards can OC everything within the limits of air coolers, Tier B (300W) if you want to give the 2970WX some more voltage on air

which gives pretty much the higher end boards out there ._.

 

actually, looking at the list I think I see why AMD wants to overhaul the motherboard platform for Zen 2 TR4. I get the feeling there'd be some stock support on X399 for up to 24-core... wait that's only one stack higher than the R9 3950X. I'm not sure what makes sense now

Stares at list.  Yeah, I do hope newer boards drop.

Though, I am using Tier D boards.  In my case, I know to not go crazy on the boards.  I would love to pick up a Creation board (since folks make custom BIOS for it), but oof every time I see its price tag.

I'm trying to imagine a non-server workload that would benefit from a 2Ghz 64 core machine...

 

I really doubt AMD brings that out for the reason that the market just has no reason to buy a $3000-4500 CPU that has such a niche use case.

Can you overclock an EPYC processor?

with the right server motherboard you certainly can, derbauer did reach 3.9ghz or 4ghz with 2 32 core cpus with first gen epyc

It was 3M Novec fluid pushed through the heatsink and VRMs using the standard server fan array at the front of the server.

One day the "Threadripper 2" thread in my sig will become a reality.

For those with no sigs turn on, here you go

I can't stop thinking about Lisa Su secretly wanting to be the first to use the words "kilocore" and "kilothread" on stage . Better get ready to hear that, we're not too far away from it.

250A... It's only 250W when you get a CPU that draws the current at 1V, which I suspect even the 64 core to need more voltage for this current

when you want a lot of PCIe lanes for relativly cheap.
