AMD 3rd Gen Threadripper Coming This October to Take on Intel's New HEDT Lineup?

AMD is planning to surprise Intel by unveiling its 3rd generation Ryzen Threadripper HEDT (high-end desktop) processor lineup around the same time Intel launches its 10th generation Core "Cascade Lake-X" processor and the "Glacial Falls" HEDT platform, according to sources in the motherboard industry, speaking with DigiTimes. We're fairly sure the sources aren't referring to AMD's 16-core Ryzen 9 3950X processor, because it has already been announced and will be available in September.

The 3rd generation Ryzen Threadripper will likely be a derivative of the company's "Rome" multi-chip module, and compatible with existing socket TR4 motherboards with a BIOS update, although a new chipset could also be launched to enable PCI-Express gen 4.0. AMD has the option to deploy up to 64 CPU cores across eight 7 nm "Zen 2" chiplets, while the 12 nm I/O controller die will be likely reconfigured for the HEDT platform with a monolithic 4-channel DDR4 memory interface and 64 PCIe gen 4.0 lanes. It's capable of 8 memory channels on the 2nd generation EPYC.

Finally some news. My 1950x is great but this will finally fix the constant requirement of switching from creator mode to Gaming mode.

That will be the biggest dividend of 3rd gen TR: Windows 1903 performs CCX-localization automatically. Memory localization won't be needed since all cores talk to an I/O die. This die has a monolithic quad-channel memory I/O, so it's finally possible for a core to enjoy quad-channel bandwidth the way Intel HEDT cores do.

I don't really need anymore than 16 cores, but I'm interested for the PCI-E lanes. More info needs to leak! lol.

Wow, that will be interesting. With AMD having really catched up on tha AVX performance a 32 core CPU would be a real powerhouse for me :)

Probably up to 48 cores only. 7nm+ is supposed to improve yields and make it cheaper to produce... so cheap enough to give 64 cores for us non-datacenter plebs with Threadripper series. Still doubt the rumor though...

Yeah, I also doubt they will make a 64 core straight on. Remember than on first gen Zen they gave only half of the cores available, so I don't see any reason they wouldn't do the same this time. My bet is 48 cores max this gen, for refresh 64 cores and then Zen 3.
LE: Well, thinking about it some more, this can be a chance for AMD to make some big money and have no competition whatsoever from Intel. Just look at 3900X, it sells pretty well, even though it costs 500$. People are willing to pay big money for big performance, so I guess it would be a good move to release a 64 cores threadripper. It would be unmatched by Intel on price, performance and it would give AMD a boost in customer opinion, since it has been quite long since AMD didn't had the best CPU in the market, period. Money wise, I don't think they can make the same profit as they make with ... 3900X, if they keep the same price as the 2990WX. For 500$ they sell now two defective dies (6+6 cores) so, 250$ per die.
A 64 core threadripper is made of 8 fully functional dies, the IO dies must also be fully functional and if they sell it for 2000$, they get the same 250$ per die, but now it must be a perfect die. I don't know, only thing I can say is that it would be nice from them to have a 64 core CPU for desktop.

AMD already hinted that 3rd gen Threadripper going up-to 64C, listen Lisa Su and other AMD stuff - they all use : "....Move Up, Up" this refers that this Gen will move 2 steps above current 32C limit on TR, thus there will be 48C and 64C.
“If mainstream is moving up, then Threadripper will have to move up, up—and that’s what we’re working on,” Su said.
The interesting part will be the Chiplet/Cache config for 16c~32C parts:
16C 64MB or 128MB with 4 chiplets
32C 128MB or 256MB with 8 chiplets

In Epyc linup they offer all the configs with diff cach sized due to num of chiplets used.
Also- looks like the Chipset will use the large I/O die from Rome- how they gonna cool 25~50W chipset?

P.S: Intel is already reacting in secter to upcoming EPYC/TR with "new" 240W TDP parts for extra 50% price increase:

What would you bench on Dual socket ThreadRipper with 128C/256T@ 4.3Ghz all core OC? R20? :)
Will be funny to break 100K in Cinebench R20 :-).

Crysis, obviously AssCreed Odyssey. Maybe 128 cores can finally handle 2 layers of protection plus Ubisoft-quality console port and the curve starts going back up again :D

Finally some good news for the people who want 16 cores with quad channel memory, ddr4 3200 dual channel does not even make sense for 12 cores, let alone 16 cores.

TR3 will be massively popular with Professional Chessplayers! When Ryzen first launched back in 2017 it was quickly recognized as the go-to processor both for performance and economy.

"One of the most important days in years for computer consumers was the launch yesterday of AMD’s newest microprocessor, the R7 Ryzen. For a decade, AMD had been out of the race in high-end desktop CPUs, but the release of the new architecture has shown it is not only back, but at a far more affordable price, and what is more: the best deal around for chess analysis."

Eagerly waiting for this, be it 48 or 64 cores, especially with the Zen 2 cores able to power down as much as they do when not in use will be impressive!

Agreed. And how is >32 cores going to make sense for only quad channel memory? :rolleyes:
The 16-core and possibly the 24-core models will be the interesting products for workstation users, assuming they don't run into major bottlenecks, latency issues etc.
The amount of non-synthetic and non-server applications which can scale close to 32 cores is limited, let alone beyond that. And any CPU which has to sacrifice clock speed to have more cores is really not well suited for workstations.

Exactly, what is the point of them releasing a 64 cores, even a 32 cores is already starving for memory bandwidth. I really don't know what amd will do. DDR4 at 3200mhz gave them some bandwidth from 2933mhz but still not enough. I dont think they will release a 64 cores this time unless they go ddr5. DDR5 in 2019, not happening, ddr5 probably in q4 2020, q1 2021.

What if Amd goes off with 8 channel memory ? Then ?

That is a possibility, reason I said "I really don't know what amd will do". AMD is aware since last treadripper release, the 32 cores was with performance constraints and they know is due to the memory bandwidth.

That would be nice, but would break compatibility with existing CPUs.

Thats exactly what the bottle neck was and now i guess they will deliver. Intel designed their 6-channel to derive most out or LGA3647. I remember somewhere the same discussion took place in a conference where the only reason Intel managed to exceed was because of memory channels and Amd was on that expression till now. Its very likely they will introduce 8-channel as they said previously.

Nope it wont break compatibility after all. You see if core i5 7640x with dual channel memory can go along 7820x 7960x with quad channel on one same plateform x299. Why cant quad channel go along 8 channel ? These companies always provide if they really want to. Unless Amd makes a new chipset and declares no backward compatibility. Then thats another story.

8 channels needs 8 individual sets of traces to the memory sockets, while multiple memory sockets on a channel shares the traces. The only way to support this is if AMD planned this from the beginning and made it a requirement for all TR4 motherboards. Did they do that?

Only Amd can answer that. But if it needs to be made from the beginning. There might be still a chance to make it backward compatible. Remember that the socket contains LGA of 4094 pins. Its not compulsory that all the pins are serving their purpose. Amd does not have a habit like Intel to change socket once in a while forcing consumers to change sockets. Means companies always create the socket and there are alot of points where should i say room for future processors or purposes. Amd TR4 has a alot of count compared to Intel and there is a fair chance it may work on higher grounds on the same socket. Back and forth compatibility.

We know that AMD uses top 5% silicons for TR, and last gen 2950X had 4.4Ghz boost vs 4.3Ghz on 2700X, so looks like the 16C TR should have 4.8Ghz max boost and if it will be using 4x4c chiplets then the heat density will be low and they can boost to higher clocks in All core and ~50% utilization, it would be funny if it's going to be "World Fasted Gaming CPU" on HEDT platform :),
