Threadripper BUILDERS thread

[gdansk]

I'm worried about availability. And pricing. By now AMD knows they have gold and may price it high.
But it's going to be one hell of an upgrade for me.

 

[Paratus]

I see techpowerup are carrying a story that X399 will not be compatible with TR3.

AMD TRX40 Chipset Not Compatible with 1st and 2nd Gen Threadrippers

AMD is giving finishing touches to its 3rd generation Ryzen Threadripper HEDT processor lineup, and the first wave of these chips, starting with a 24-core model, will launch alongside the AMD TRX40 chipset. It turns out that the chipset won't be compatible with 1st and 2nd generation Ryzen...

Not quite sure I believe this. Not yet anyway.

That’ll be disappointing. I was hoping for a 3rd gen 16 core Threadripper to upgrade to.

 

[kensiko30]

I believe that threadripper popularity will lower even more now with the availability of 16 cores on am4. Threadripper will be a really niche market.

While cores played a part in my TR build, PCIe lanes were my main reason. If the 24-core comes out at a thousand, that's 8 more cores for about the same as my 16-core. PCIe 4.0 would be nice, but I'm afraid of what the motherboards would cost.

TPU typically a reliable resource, so I'd say to not get your hopes up. At least if it ends up being true Mark will get to play with a new board.

I am totally content with 8-core Ryzen for my current needs, so this is purely HEDT porn for me anyway.

Given Rome is socket compatible with socket SP3 - and socket TR4 (aka SP3r2) is a mere increment off that - it'd mean AMD have went out of their way not to support X399 with the threadripper branch of Rome.

Which means I don't quite believe TechPowerUp yet.


If there are TR3 CPUs with 8ch memory, then yes, obviously X399 is not going to deliver 8 channels of DDR4. But I'd hope that doesn't mean SP3r2 and X399 is being abandoned.

"It turns out that the chipset won't be compatible with 1st and 2nd generation Ryzen Threadripper processors."

I believe AMD should be more open about this to allow people to plan and not make wrong purchase decisions!

I just got 2920X planning it as a interim cpu in a TRX40 board, before I will get something better. I will have to resell it or change plans and get some x399 board instead. But I need to buy the x399 board now while they still last!

AMD, WE NEED INFORMATION ! NOW !!!

 

[Atari2600]

Well, like I said - I don't believe the techpowerup rumour just yet.


Anandtech are saying they are "expecting compatibility with current X399 motherboards".

 

[Kocicak]

I need real information, not rumours or beliefs, I do not know what to do now! If I will have to resell the 2920X, I need to do it quickly.

I'd like to know as well. I would've thought it would be similar to AM4 - you want PCIe 4.0 you need a new motherboard and if not a current board is fine.

 

[Atari2600]

Anyone on twitter want to twit* the AMD official and see if you get a response?

*twit is the proper adjective for anything on twitter.

 

[Justinbaileyman]

We dont have any pictures of a single motherboard yet let a lone any compatibility info and there is only 2 weeks to go till launch may be 3 and 4 at the very latest??
AMD needs to drop the ball here and show us the goods and stop leaving everyone in the dark!!
I hate all these secrets, it very dishonoring and deceptive!!
You would think in order to hype up a product and get everyone excited to purchase said item they would advertise the snot out of it not keep everyone in the dark to play guessing games..

 

[Kocicak]

The lack of information about any motherboard is curious, because manufacturers must be already siting on piles of boards ready to ship.

 

[Justinbaileyman]

Well even with X570 and last gen x399, we got motherboard info and pictures a month or two before launch and were able to purchase x399 motherboards almost an entire month before the launch of the 1920x and 1950x cpu's.

This waiting game they are playing has got me worried they are gonna pull a paper launch and we wont actually see anything till around the first of the year..
Then again, it could just be me being paranoid..

 

[nnunn]

The optimist in me thinks new Threadripper is so good, AMD don't wanna divert too much interest from Rome.

Rumour mill has 3 chipsets. TRX40, TRX80 and WRX80


Now why the ____ would AMD release 3 chipsets into a niche market when they can cover the entire range of desktop with 3 chipsets (A320, B450, X570)? Dunno how many SP3 chipsets there are - cannot find much info on that.

I could just about see the logic in two chipsets, one for 4 ch DDR4 the other 8ch DDR4. But if I were AMD, I'd point anyone looking 8 channels of DDR4 toward their EYPC line rather than Threadripper - and release a 24 or 32 core speedster (replacement for EPYC 7371).

If anyone needs 8ch of memory, then their tasks are of sufficient size that they would get better ROI by using dedicated farms for their HPC rather than individual workstations in ATX boxes. Which means racks. Which means EYPC.

... and what on earth would differentiate TRX80 and WRX80?


Hopefully the rumour mill is full of crap and we get:
- TRX40. 4 channel DDR4 with support for PCIe4
- X399. 4 channel DDR4 with support for PCIe3.

More pcie, possibly. You've got lines that would have supported a second processor, presumably.

Hopefully the rumour mill is full of crap and we get:
- TRX40. 4 channel DDR4 with support for PCIe4
- X399. 4 channel DDR4 with support for PCIe3.

Well, yes, I hope so too, but I suspect that we're in danger of losing that option, which is why we're not hearing about motherboards. Alternatively, same thing that's pushing out the 3950x launch is delaying TR. But it wouldn't shock me if the complex routing they had to do for the 8+1 layout is affecting power quality/delivery.

 

[nnunn]

... and what on earth would differentiate TRX80 and WRX80?

Could AMD switch a couple of those EPYC chiplets for co-processors?

Replacing some of those 64 Rome cores wth 64-bit tensor.cores could give them a dgemm monster.
Or they could drop in a couple of ray-tracing chiplets for real ray-tracing.

Work-stations done right?

There are no chipsets for SP3. The southbridge is fully integrated into the Epyc 7000 processors (Naples, Rome) themselves.

That is interesting.

So on TR1 and TR2, what does the X399 chipset do?

*goes off to rummage down the back of the interwebz sofa*

 

[Atari2600]

*comes back from rummaging down the back of the interwebz sofa*

Original credit I think should go to a certain Ian Cutress.

So the chipset doesn't actually run the DRAM slots at all.


Now I am really confused as to why (a) 3 new chipsets are supposedly required for TR3 and (b) how compatibility cannot be maintained since communication between CPU and chipset is over 4x PCIe lanes [excepting PCIe 4.0 of course]

a) it's probably not, though of course you can take advantage of pcie4.0 and a more capable chipset :shrug:
b) I'm betting on power stability, rather than communication compatibility

Obviously, though, 8 channel DRAM is going to require a new board. I assume we're not talking about that.

BTW, this is a builders thread, not the rumor mill. Just saying. :-)

7nm 24 core chip is 3960X

Drooling starts.... 32cores@4.8 ghz ? (a guess) I only have 32 cores@3.8, and its handicapped on memory access also compared to the new 3000 series.

And as far as TDP ? and cooling ? the Noctura cooler with dual fans I have on a 2970wx and its quite cool (stock). I have a wraithripper on my second 2990wx at stock and it does OK. So I am pretty sure I am OK for upgrades, except needing some more Noctura fans (unless I can find a way to mount standard fans on them)

Just imagine dual 3950x's as far as what they can do.
