Threadripper on Zen+ 32 Cores - Launching Q3 2018

[chroniclard]

lol at that Intel cooler

 

[humbug]

lol.... Fail!

Hey we hit 5ghz, you only need nuclear power plant style cooling to sustain it!

 

[HeX]

Any news on clock speeds?

3GHz base, 3.4GHz boost is what's floating around for the 32c part.

 

[AETAaAS]

From what I read on Anandtech the TDP of T2 32 core will be up around the 250 watt mark, to get to to 180 watts they would probably have to drop the frequency to around 2.2 Ghz with a boost of around 3 Ghz meaning which would hurt it's viability as a monster HEDT CPU (a low clock frequency would make it useless for running games). 250 watts isn't a problem though, remember AMD have already given us the FX-9590 which was 220 watts+.

Also remember AMD's software allows you to setup your CCX's depending on your workload, so if you want to play a game your not going to need 32 cores so can setup your CPU to disable say 3 of the CCX's and run it like a regular Ryzen 2700 with clocks at 4Ghz+ and when you want to do some heavy duty rendering or HPC work turn those CCX's back on (core frequency goes back down core count goes up) and you have a mini super computer at your disposal.

Oh no, I didn't mean that the new part would be 180W. I was replying to humbug's post above mine, to rebuff the idea that a 32 core TR was just some kind of stunt.

If as you say, make use of a small number of cores, I wonder if features like XFR2, PB2 and PBO will apply to TR2 (the slide in the OP makes mention of 2nd Gen features?). If there is 'opportunistic' boosting, this would be an interesting chip in many ways since you would hopefully already have the cooling and power system to drive it hard.

You just noticed that ?? Knew it straight up when I'w seen 5ghz all core and score that its at lest chilled water.
Like plain calculation of power needed to run 5ghz on 6 cores on 8700k is around 220 watts x 4.7 more cores = 1034 watts give or take.
There is nothing besides chilled water or phase change cooling that can pull that sort of performance off. Add on top of that around 300 for motherboard ect You are looking at 1500w draw

TBH intel should have just slammed that LN2 closed loop from K1ngpin on it and run it at something even faster.

But power delivery must be MASSIVE problem like on circut level over 1KW in to souch small area !!!!

I don't understand the hostility to the 5Ghz 28C Intel Part. It is an incredible achievement in so many ways, where the only issue I have is not running CB at stock and then at 5Ghz.
A >700mm^2 die, 28 cores, huge cache, all running at 5GHz! Wow!

As an objective metric, the processor set the record for a single processor CB score. You can't fault what an achievement that is.

When the consumer parts release, they will be running at close to half that frequency at significantly lower voltages. They will consume a lot less power.

I do have huge reservations about the cost, however, as a die right on the reticle limit is going to cost a fortune to fab with the usual Intel tax added...

Because it's akin to AMD launching Ryzen 2 as a 6GHz part because someone managed to get it to that speed on LN2...

Intel did it to grab headlines and undermine AMD's TR2 launch and it's backfired on them horribly.

I'm surprised the cops didn't raid them suspecting due to all the power that was being drawn they were running a undercover weed growing operation.

On the 32C TR2 part, I'm curious about the following, which are yet to be answered:

• How will the two extra physical die's interact with memory via IMC's on separate physical dies, and what will the bandwidth/latency impact?
  • I suspect the improved IMC and higher clocked infinity fabric (better 12nm RF libraries?) will improve the above, inline with Zen+
• Will quad channel ram bandwidth bottleneck the processor?
• What was the original specification for TDP and power placed on the X399 platform, i.e. did AMD specify 250W for X399 to ensure current motherboards can handle the higher power for TR2?

I suppose all this will come out soon, but interesting details.

 

[Minstadave]

It’s a bit like a 7Ghz 8700k on LN2. Impressive but totally meaningless to the consumer as no one will ever run one. Massively expensive, likely extremely cherry picked on exotic cooling using vast amounts of power.

It’s a desperate stunt to compete with 32c64t Threadripper which is hugely more impressive in the real world.

 

[sideways14a]

I dont think the problem was doing the 5Ghz stunt, it is indeed quite an achievement and on its own is cool.

But... this wasnt done for overclocking coolness... it was done to **** on AMDs parade the next day, very obvious and rather pointless as intel needs a much bigger gun to bring to the fight.

 

[Armageus]

I don't understand the hostility to the 5Ghz 28C Intel Part.

Because it's not a real 5ghz part and requires a ridiculously expensive cooling solution.

When the consumer parts release, they will be running at close to half that frequency at significantly lower voltages. They will consume a lot less power.

The enterprise part already does consume less power - there won't be a consumer part though.

I do have huge reservations about the cost, however, as a die right on the reticle limit is going to cost a fortune to fab with the usual Intel tax added...

The price is essentially already known from the Xeon part - $10000.

Its no different to Threadripper 1, but this is Zen+ which had a 25% reduction in latency, that should carry over to Threadripper 2

I suspect the improved IMC and higher clocked infinity fabric (better 12nm RF libraries?) will improve the above, inline with Zen+

Right

Will quad channel ram bandwidth bottleneck the processor?

Compared to what? Ryzen is dual channel, Threadripper 1 was also quad, the fact that its 32 core will make no difference to the memory performance and it will not bottleck the 32 cores, it doesn't work like that.

What was the original specification for TDP and power placed on the X399 platform, i.e. did AMD specify 250W for X399 to ensure current motherboards can handle the higher power for TR2?

TR1 was 180 watts, so its 70 Watts higher, 250 Watts is not that high, a good existing X399 motherboard will easily cope with that with some room for overclocking.
Some board partners have beefed up their VRMs, i would think if you wanted to get high overclocks out of TR2 you will need these newer boards with better VRMs.

You know what i find really interesting, AMD didn't have the 32 core Threadripper or the Spire Ripper air cooler there, only the 24 core CPU which they demoed against Intel's 18 core 7980XE.

To me this is AMD reacting to Intel's 28 core stunt, this is AMD saying "you know what Intel, #### you we can play that game too, only better, 32 cores and a box cooler to make the point about our power efficiency, stitch that!!!!!!"

They demoed the 32 also.

First was a demo of the 24 core vs intels 18 core then they added more effects to the demo and ran the 32 core still with an air cooler. We didn't physically see any of the systems, we saw the renders being done. It might have been out of shot since we see the camera view not the audience view.

You can see the part where AMD breaks out the demos here: https://www.youtube.com/watch?v=mhEu3RiCLpg&t=74m36s

Intel must have thought AMD was going to push out an incremental improvement so running their stunt into AMD revealing another round of core count doubling... yeah... time to keep a low profile.

 

[humbug]

Ah ok, thanks ^^^

 

[doodah]

Exciting times ahead, love competition

 

[faceman123]

Thanks AMD, because of you we've moved passed the quad core monopoly of intel

 

[Kelt]

Thanks AMD, because of you we've moved passed the quad core monopoly of intel

We owe a big thanks to AMD.

As mentioned above, we'd still be on dual core 32 bit chips costing £600+ if it was up to Intel.

 

[Zeed]

If AMD wants they can drop that water chiller on 32 core TR and GAME ON or next step go phase change cooling :]
