The 64-core 3990x isn't released until 7th February and the usual e-tailers don't have price listings. I did however spot this listing at box:

https://www.box.co.uk/AMD-Ryzen-Threadr ... 69181.html

So, the eye watering price point is ... £3,760!

... and that doesn't even include a cooler!

Nope, or case, psu, RAM, motherboard, etc for a build ...

...and what's the betting that delivery is extra?

Probably via G4 (what used to be called Securicor back in the olden days), with at least two armed guards. ;-)

And I doubt there's an option to have it sent in a plain brown wrapper by 1st Class mail.

Thinking about it, this could quite easily lead to some people ordering one (or more) and then claiming that it/they never arrived...

I'm sure some scammers would be thinking about this real soon.

And of course, being small and expensive, there's the possibility of more trucks being hijacked as was the case in the past when memory prices got obscene and before that when VCR's were launched and were highly sought after and 40 foot containers would be intercepted by crooks.

Sure give me 2 of them for my dual socket TR4 board

I'm going quad socket for this one. It's the only way to crunch!!!

I've got my name down for the next one of these https://www.cray.com/company/news-and-m ... ss-release once they've ironed the bugs out :D

1.5 exaflops?! That's quite a leap. I don't think we've hit the first exascale system yet (although should be this year).

The first one is due next year, I'm hoping they improve it before my order is shipped :D

So, this 64 core beast is due for release tomorrow!

Looking forward to the first reviews. I assume they might not be live until something like 2pm our time, as releases are generally pivoted around the US.

Tomorrow? I've just ordered two from this bloke new to EBay who was selling them for £3,000 each with free delivery. Couldn't pass them up at that price even if I did have to pay in advance :D

I wonder if the reviewers have chips already as it'll be a bit of a rushed review otherwise as they all try to be first?

Hi Mark

Good luck with that :o Hope you haven't paid them with cash in a brown envelope that was collected by a courier recently?

It's quite normal to release actual product in advance of a "release date" and to place an embargo on any reports or reviews - in the audio industry, it is the done thing, unless you want to give one reviewer an "exclusive" or "first test" option.

And if a reviewer breaks the embargo, they never get advance product again, so it's not in reviewers interests to break the embargo.

Base clock 2.9GHz
Boost clock 4.3GHz

UK stock - https://www.overclockers.co.uk/amd-ryze ... bw-am.html - £3,690

https://www.tomshardware.com/reviews/am ... 90x-review
The 3990X is based on the EPYC Rome 7702P that is designed for single-socket servers, so it comes with the same 64 cores and 128 threads paired with an amazing 256MB of L3 and 32MB of L2 cache.

The two processors have plenty of similarities, but the difference between the two largely boils down to clock rates, memory channels, and the number of PCIe 4.0 lanes.

As we can see, the Threadripper 3990X is significantly faster with up to a 2.9 GHz base and 4.3GHz boost than the EPYC 7702P, an improvement of 900 MHz and ~1 GHz, respectively.
AMD recommends 1GB to 2GB of memory capacity per thread for optimal performance
The 64-core 128-thread Threadripper 3990X is a highly-specialized processor that provides incredible performance in a narrow cross-section of workloads, but at a very attractive price point given its capabilities.

Despite using quad-channel DDR4 3200 CL14 memory, the 3990X scores relatively weakly in terms of outright memory bandwidth. We see a similar reduction in performance when looking at the difference between the 32 core 3970X and the 24 core 3960X.

All Threadripper 3000 CPUs feature the same central IO die memory controller, but our data suggests that there is a fight for the bandwidth as increasing numbers of cores are trying to carve out their fair allocation of system RAM. It will be interesting to see if this has an effect on our test results.
....
AMD’s suggestions to use 3600MHz memory (and an 1800MHz Infinity Fabric clock by default) are justified.
PBO all core boost clock 3.7GHz then drops to 3.57GHz as the cooler struggles to hold 95 degrees (Cooler Master Wraith Ripper)

PBO all core boost clock maintained at 3.8GHZ (IceGiant ProSiphon Elite)
Removing the power-limiting shackles by using PBO, AMD’s Threadripper 3990X becomes extremely thirsty. Our readings highlight power draws of around 700W at the wall once the PBO frequencies settle to sensible stable points. For the first runs, where temperature induced PBO throttles have not kicked in, we recorded almost 900W of power draw from the wall.
I think it is fair to say that the AMD Ryzen Threadripper 3990X delivers just as we expected, and that’s a good thing.
In applications that can leverage 128 threads, the performance uplifts versus alternative options are superb.
[Edit]
From Anandtech https://www.anandtech.com/show/15483/am ... x-review/3:
Unfortunately, not everything is just as straightforward as installing Windows 10 and going off on a 128 thread adventure. Most home users that have Windows typically have versions of Windows 10 Home or Windows 10 Pro The problem that these operating systems have rears its ugly head when we go above 64 threads.

Whenever Windows experiences more than 64 threads in a system, it separates those threads into processor groups. The way this is done is very rudimentary: of the enumerated cores and threads, the first 64 go into the first group, the second 64 go into the next group, and so on.

When the system is in this mode, it becomes very tricky for most software to operate properly. When a program is launched, it will be pushed into one of the processor groups based on load – if one group is busy, the program will be spawned in the other. When the program is running inside the group, unless it is processor group aware, then it can only access other threads in the same group. This means that if a multi-threaded program can use 128 threads, if it isn’t built with processor groups in mind, then it might only spawn with access to 64.

If this sounds somewhat familiar, then you may have heard of NUMA, or non-uniform memory architecture. This occurs when the CPU cores in the system might have different latencies to main memory, such as within a dual socket system: it can be quick to access the memory directly attached to its own core, but it can be a lot slower if a core needs to access memory attached to the other physical CPU. Processor groups is one way around this, to stop threads jumping from CPU to CPU. The only issue here is that despite having 128 threads on the 3990X, it’s all one CPU!

In Windows 10 Pro, this becomes a problem. We can look directly at Task Manager, the important number here though is the socket count. The system thinks that we have two sockets, just because we have a high number of threads in the system. This is a big pain, and the source of a lot of slowdowns in some benchmarks.
So don't run it on Windows :) ... or Windows 10 Enterprise/Server at least.

So, yes, looks like best case it’s maybe 65% faster than the 3970x at stock, and then - with hardcore water loops - it might be able to bring it close to 90% faster than a stock 3970x.

It looks like, even with amazing water cooling, one shouldn’t run this higher than probably 3.5GHz consistently. That is pretty epyc in any case (excuse the pun ..)

I am keen to dig through more reviews!

My favourite quote form that guru3d review is:
"Waking up in the morning and walking by that 128-threaded beast continuously makes me want to softly whisper some dirty talk to it as, man, that thing is sexy." :clap: :lol: :lol:
