Zen 2 Threadripper not coming to X399 (unofficial)

[JohnnyDiggs]

Hey. Unfortunately there is not very good news, AMD has changed its mind about making X399 compatible with the new generation.
For this reason, HEDT disappeared from all calendars and the release of these processors was forced to postpone.

Since the new processor has a new memory controller and he in a single copy (instead of two as before) had to seriously change the pins. Also, the new PCI Gen 4 standard and new power pins made a special contribution.

TRX40 and TRX80 are a new generation and a new architecture. Nothing to do with the past generation.

At the moment, all information is classified and I do not have access to it.

 

I just got my 2920X  and mobo for 75% off thinking I could get a zen 2 for cheap next year, now this comes out. I'm a sad panda.

No new Zen2 Threadripper for X399.

FYI @1usmus makes the Ryzen RAM Calculator.

Here's an alternative source (which in theory, solidifies its legitimacy):

 

Quote

1usmus is the creator of the DRAM Calculator for AMD Ryzen CPUs (his real name is Yuri Bubily) and his post on Overclock.net he said that AMD has removed X399 compatibility from its upcoming third-gen Ryzen Threadripper CPUs. There are lots of changes with the new Threadripper CPUs, which seem to have forced AMD into new chipsets for the new TR processors.

 

The new chipsets in question would be the purported TRX40 and TRX80 (really, AMD? Mix that around and it spells RTX... your competitors graphics cards) that would support the next-gen Ryzen Threadripper CPUs.

 

In his post, 1usmus explained: "Hey. Unfortunately, there is not very good news, AMD has changed its mind about making X399 compatible with the new generation. For this reason, HEDT disappeared from all calendars and the release of these processors was forced to postpone".

 

He continued: "Since the new processor has a new memory controller and he in a single copy (instead of two as before) had to seriously change the pins.

Was honestly hoping for this, x399 wasn't really ideal for the 32 core TR2.

Um, has this been proven or?

Not necessarily proven, no.

 

I would say as of now it's at the level of a WCCFTech or eTeknix or VideoCardz or Fudzilla rumor/speculation article. 

 

What I find interesting, is the post itself (which everything is based off of), was made 20+ days ago:

It's only just now getting churned up, not sure why. Though it seemed likely this was on tap after the new chipsets hit the rounds of product naming. (Also, the next chipset name had been bouncing around all of H1, which is why when the conjecture there wouldn't be a TR3 came up, there was enough "bite" to the thought since nothing seemed certain.)

 

Chatting around about this topic, it seems like there isn't a hardware-level reason they couldn't, but making a new platform lets them change wiring anyway. Epyc chips are drop-in compatible with the entire SP3 platform, so TR should be wired in such a way it isn't an issue. What is more likely the issue is that 8 channel TR parts wouldn't be drop-in for X399. This would mean AMD would need to run out separate SKUs of TR for X399 and TRX80. That's likely what AMD doesn't want to do. This way, they can launch TR3 parts and they'll work with either 4ch or 8ch memory and it won't be an issue for the end-user. 

 

Also, Intel's W-series, in response to Threadripper, is also making AMD to change up the way their HEDT platform is aligned. It makes sense because TR sold incredibly well, which means there is quite the market for that type of product. Also, moving the entire TR3 lineup over to PCIe 4.0 makes things more simple. Seeing how "well" AM4 backwards compatibility is going, AMD has made a prudent call.

If this turns out to be true, I'm glad I didn't buy into x399 thinking I'd be able to get a new Threadripper chip down the line.

[leadeater]

Only thing that makes me think this is not the case is that AMD has given a time frame for when TR2 is coming out and we have not seen enough information about new engineering sample motherboards with new sockets and chipsets at all yet, it's a bit too close to release time to have not seen any.

 

Doesn't make any difference to me at all really, just odd to have such a lack of everything if so much new product designs are required.

Could also be 6 channel to keep it out of they way of EPYC. Split platform does make the most sense to me too though.

While we view Desktop socket compatibility as valuable, for stuff like TR and it's chunk of the market it doesn't make the most sense. If you're in for ~1000USD CPU, you're in for a new 300USD motherboard. If you aren't, you can still buy X399 and a TR2 part and get a wicked system. (There's a lot of HEDT buyers that buy in at the end of a generation because of platform stability reasons. LMG being one of them.)

 

We'll see what products pop out. We've already seen the platform show up in benchmark databases. (Sharktooth) and the 32c Zen2 part is hanging out there. It'll be interesting to see exactly what AMD is up to with the chipsets and what their purpose is. AMD may actually be using the Ryzen IOD again as a chipset to really extend the TR range. 84 PCIe 4.0 "lanes" maybe?

[porina]

When the news started to come out that more memory channels were going to be supported, that was a big signal that a new chipset would be needed. I wouldn't rule out they could do a split launch, some on old chipset constrained by quad channel ram, some requiring new chipset with more.

That, or perhaps AMD is just keeping a tight lid on any news about the product.  We've seen how AMD can be very tight lipped when they choose to.

Don't you mean TR3?  TR2 came out like last year.

He was probably conflating it with Zen2.  Or he just mis-typed.

[MeatFeastMan]

To be honest..I think they postponed it a month or two because of supply issues, not because of new motherboards. That's as clear as day. Launching Navi, Ryzen, EPYC and Threadripper all at once would have been a nightmare with all the supply problems TSMC have had. They are still struggling even now, 3900x is nowhere to be seen and 3950x had to be delayed.

 

That's why they are only going with a first wave of Threadripper CPU's.

 

I can't imagine they'd change the pins with like 2 months till launch. This would have all been planned way before launch surely.

 

It's annoying that you can't use x399, but..I think there's a reason for that. One youtuber a while back suggested they could add some AI stuff on there, maybe to help with content creation purposes like streaming and so on..that's my bet too, and I'll be taking a look at the 24 core if that's what they intend on doing.

It was more I forgot there has been two generations of TR because meh, same thing with a spit shine.

[Antistatic12]

I'm getting the feeling 3rd gen TR might be getting delayed,  has there been a decent leak on mobo's yet? November launch isn't that far away.

It won't be because they've specifically said only up to 24 cores, suggesting they are lacking in supply but have enough for one wave of the smaller threadripper parts.

 

There has been one or two leaks about TRX and WRX motherboards, but not that much. This is an example:

[Doobeedoo]

Hmm could make sense really. It's quite a change this time CPU wise. Besides it's not the mainstream platform too.

It was supposed to come out this month, and was delayed until November alongside the 3950x.

Was there any credible indication that TR was due this month? The first I heard about any date was November.

So AMD is pulling an Intel. 2 CPU generation before another socket change. Heh

Only on HEDT, but it isn't wholly confirmed yet. However, for the type of buyer that they deal with and the technical aspects, that's fine. Oddly, AMD will still be selling a good chunk of TR2 parts for a while, since a lot of HEDT buyers like to buy in after the next generation launches. Which might actually have more sway on this decision process than at first glance. New BIOS for X399 would cause issues with TR1/2 parts, more than likely.

[Unixsystem]

This makes a lot of sense if the other rumors of Zen 4 being DDR5/PCIE5 are true. That way we get two generations on each chipset/socket. More would ways be nice, but 2 seems totally reasonable for an enthusiast part, especially since we appear to be in a pretty quick turnaround for major platform level overhauls these last/next few years. 

[DaRk0]

I guess I'm holding onto my 1920x until my next platform switch - which will take place in about 5 years or so.

DDR5 isn't even deployed yet (as far as i can tell as an outsider), and the first public demos of PCIe 5 / CXL only occurred earlier this week. this isn't coming within the next month. maybe not even a year ._.

He was talking about zen 4 not zen 2. Threadripper 3000 = zen 2. 

So that would make sense, threadripper 1000 and 2000 are intercompatible, 3000 and 4000, and then 5000(zen 4) would be ddr5, and would come out in 2021.
