I wanted an 4 mem-channel 16 core but it seems the leaks only show 24 cores and up.
16 core I can ALSO use for games but 24 cores, I don't think that will work well?
Buying to disable 8 cores isn't really acceptable.

I will sell you a 1950x 16 core really cheap after they come out with threadripper3. I have 5 to upgrade !

I would be very surprised if ti does not have a 16 core version. Even a 12 core would not surprise me as well.

From what Videocardz said there's only a 24 core and a 32 core. A 48 core, maybe on a different socket is coming in January.



That's what Ryzen is for.

AM4 has fewer memory channels and less PCIe lanes to start. Sometimes you need more of one than the other depending on usage.

Current threadripper has a 8 core chip, 1900x, as well as the 2000 desktop chips. And the 2920x is a 12 core chip similar to the currnet 3000 series desktop.

I suspect that the 48 and eventual 64c models (maybe wait for Zen 3 for that) are going to be WX models using the WRX80 8 memory lane chipset rumored awhile back. So will basically have some platform limitations but basically be SP Epyc's.

The who main new Threadrippers will be 32 and 64 cores. 24 is the "budget option."

I believe that the 24 core will cost 999 USD, while there will be higher "cost of a ticket" to access the platform - motherboards will be expensive.

AMD didn't know what to do with Threadripper with the first two gens. The market for what you specifically ask for isn't big enough.

AMD said multiple times earlier this year that the low core-count Threadrippers didn't sell. You won't see Threadrippers with the same or even similar core count this year. You should fully expect 24 cores and up only.

There was a 16C Castle Peak Threadripper on the September product master, though:
CPK DT Ryzen Threadripper 16C 280W SP3R3

This doesn't guarantee that they'll launch a 16C Threadripper but it's possible.

That list is out of date. Many of the products on there aren't hitting the market, alongside some that are, are not contained in that list.

280w for a 16c? good grief!!
If you want a 16c threadripper 3000 just get Epyc Rome which only runs at 155w and are also overclockable, but would not even come close to hitting that 280w mark.

Plus it would be like half the cost of threadripper 3000 im guessing.
I dont even think there are coolers out there that can even cool 280w reasonably.

Maybe need something like a double or triple thick 360mm or 420mm rad just to keep these stinking monsters cool.
I hope that 280w for the 16c is a typo or an error because I was looking forward to purchasing a 16c threadripper 3000 if there was ever gonna be a 16c part and at a reasonable price that is.
I guess we'll know more here shorlty, like some time tomorrow right??

Once you get out of the ideal frequency range, power consumption starts going up dramatically. EPYC 7302P only has a 3Ghz base and 3.3Ghz turbo in that 155 Watt TDP. While that performance is great for power/performance balance in the Datacenter, those clocks are not desirable in the HEDT market, where users typically only have 1 system, not a rack full, and they want that system to run as absolutely fast as possible. Threadripper 2's 2950X was a 3.5Ghz base and 4.4 Turbo for it's 180 Watt TDP.

My belief is that if there really is a 280 Watt TDP 16 Core Threadripper, they'll use the power budget to keep clocks around low 4Ghz All-core, 4.7 Ghz Boost to go up against the 14 core, 250W TDP i9-9990XE.

As for cooling, the Noctua NH-U14S TR4-SP3 had no issues keeping the 2970WX below 70C in high load testing, and that's with a 250 Watt TDP. I imagine it will still be able to keep up with a 280 Watt TDP as well.

So if we assume there is no 16 core 4 channel version anytime soon.
Do you think the 24 core version can be configured (before boot) to work equally like an 3950X? (VR/games, simulations, video editing)

If it are 3 * 8 core dies then basically you have to disable 1 die to get the same effect, obviously if these are 'bad' 32 cores (4 dies) then there will be no working 8 core die present, only 6 cores.

Just let all 24 cores work. It should not cause any problems.

Because of the design of Zen 2 with an I/O die that manages the memory you shouldn't need to disable chiplets, as it shouldn't cause the problems that impacted the previous Threadripper designs.

I dont know if thats gonna be true this time around for an 280w cpu.
My Noctua NH-U14S TR4-SP3 barely kept my 2950x at stock cool enough while video encoding and that was only 180w.
If I remember correctly I was seeing temps between 72-76c while encoding.
Then when finished it would quickly drop to like 38-42c when doing nothing or light work like surfing the interwebs and watching youtubes..
I bet they are gonna recommend at least a twin tower cooler.
Whether Im right or wrong, I am still excited to see what were getting on the 19th.
I hope we get some real info tomorrow for the TR 3000 and 3950x..
AMD keeps stringing us all along promising the items or even news and then when that time comes they say next week next week and then its next month next month and so on and so forth.
Very frustrating!!

It’s interesting that with zen2 the ‘worst of the chiplets’ might not be the cheaper one, that might be now the ‘middle one’.

Let me first explain zen1 to get to the point I want to make, Zen1 cpu line example:

Specs

Config

Type

CPU

Price $
‘Profit’ over cheaper
4 core / 4 thread1 chip
L​
Ryzen 3 1200
$109​
0$​
4 core / 8 thread1 chip
L​
Ryzen 5 1400
$169​
60$​
6 core / 12 thread1 chip
M​
Ryzen 5 1600
$219​
110$​
8 core / 16 thread1 chip
H​
Ryzen 7 1700
$329​
220$​
8 core / 16 thread1 chip
H​
Ryzen 7 1700X
$399​
290$​
Type is total number of cores enabled: L-Low (4) M-Mid (6) H-High(8)

Since they all cost the same to make to amd, what I’m trying to highlight here is how much amd would profit out of the same cpu die, from each different line or segment if you prefer. So for amd sells us the worst bin of them, being the case of the Ryzen 3 1200 for zen1 the most cut down of them. The point I’m trying to make in here is that the ‘bad one’ the ‘worst of the chip(let)s’ is also the cheaper one in zen1!

Now zen2 cpu line example:

Specs

Config

Type

CPU

Price $
‘Profit’ over cheaper
6 core / 12 thread2 chip
M​
Ryzen 5 3600
$199​
0$​
8 core / 16 thread2 chip
H​
Ryzen 7 3700X
$329​
130$​
8 core / 16 thread2 chip
H​
Ryzen 7 3800X
$399​
200$​
12 core / 24 thread3 chip
M​
Ryzen 9 3900X
$499​
300$​
16 core / 32 thread3 chip
H​
Ryzen 9 3950X
$749​
550$​

Now breaking the cost of the ‘chips’, since amd can sell the R5 3600 for $199 and have some profit, let’s assume from the total of what we pay is 50$ for each chip, the rest of the money is for the retail margins, cooler, box, … so the 3900X obvious gets an hit for the extra chip over the other ones with two chips, but not bad for an cpu that sells for $499 instead of $199.

Now imagine the R3 1200 version of zen 2 that still does not exist and probably won’t:

Specs

Config

Type

CPU

Price $
‘Profit’ over cheaper
6 core / 12 thread2 chip
M​
Ryzen 5 3600
$199​
0$​
4 core / 4 thread2 chip
L​
Ryzen 3 3200
$109​
-90$​

Doesn’t look good right? Now let’s reuse the ‘worst of the chiplets’ on the am4, TR and even for Epyc:

Specs

Config

Type

CPU

Price $
‘Profit’ over cheaper
6 core / 12 thread2 chip
M​
Ryzen 5 3600
$199​
0$​
8 core / 16 thread3 chip
L​
Ryzen 7 3750
$379​
180$​
16 core / 32 thread5 chip
L​
‘TR 3955X’
$599​
400$​
24 core / 48 thread5 chip
M​
TR 3960X
‘$999’​
800$​
32 core / 64 thread9 chip
L​
‘TR 3975X’
$1400​
1201$​
32 core / 64 thread9 chip
L​
EPYC 7452
$2025​
1826$​

Now Amd is able to sell the ‘worst of the chiplets’ at better margins that the 3600 which is an higher bin vs the ones that will be used in the R7 3750, and even reuse it in ThreadRipper and Epyc for even more profit than creating 4 core/4 thread or 4 core/8 thread models in the am4 platform that would give them potato profits. The ‘worst of them all’ doesn’t look so bad does it?

With this in mind imagine the possibility of amd get an risk manufacturing of 5nm with lots of damaged cores because of the earlier access/release* they can disable half of it without a problem, because the lower bin no longer have to be used on the cheaper part.
*Just to point out they could be even earlier than the mobile guys if they want to, because with the mobile guys all the chip has to work so `all` parts of the chip need to be ok to function properly.

Resuming using the 4 core chiplets on the TR it has 16 core or 32 core, it would be the best thing they could do and I think they will do it, it also depends on yields, but even if they are high (with more M and H parts than L), doing it just for product segmentation and gather better pricing from all parts could be good for them.

Sorry for the long post ;)

The really defective parts are likely being sold as Epycs, when you factor in that they don't need to clock so high. There's an 8 core model with 32 MB L3, 64 MB and 128 MB.

The cache will be spread over 3 dies and the average clock will be lower.
I want to see it first before I call an 24 core a gaming CPU.
