Yes and also the dual EPYC was at that time very much more expensive than the Threadrippers. Mind you I did not understand the incapability of the TR2990 to communicate properly internally - something I understand has been corrected with TR3.

The reviewers of the 2990wx all pretty much reported that it would be "really fast" on a narrow selection of computation tasks. You and I (and others) learned the hard way that the task had to run in cpu cache to run really fast. The memory bottleneck was/is severe if you wanted to run much more than 26 Seti@Home cpu threads.

Ordered a Sapphire AMD RX 5700 XT Nitro+ 8GB. My local store can deliver it for cheaper than the bigger stores can, but still it'll set me back €500,-

My system is now complete...
Fractal Design Define S2 case (white)
Asrock Taichi X470 motherboard
Ryzen 3900X
32GB HyperX DDR4-3200
Samsung 970 Evo Plus 1TB NVMe M.2 SSD
Samsung 860 Evo 1TB SSD
Corsair H100i RGB Platinum SE water cooling AIO
Seasonic PX-850 Focus Platinum 850W PSU

I may need another HDD, but that's not urgently needed. :)

I hope you’re not planning to use that on SETI.

5700/XT produce invalid results on SETI.

Nope, gaming only. I run Seti on my Android devices.

I signed up for one of those "in stock" notifiers and now I am getting hit daily with an email for an "in stock" AMD 3950x.

And the prices start at $800-$900+

:( Oh well, I guess I will just have to "limp along" on the used AMD 3900x I got. Its amazing what a lack of demand will do. You can now buy AMD 3900x's for near or at the MSRP!

I also lucked into a 3 day "used" AMD 2700x for $155 (with stock cooler). The story appears to be he gave it a 3 day try out and then decided to sell it... Hmm......

Anyway, my Mining Am4 MB will get a Christmas present and the Mining Rig I bought will get a MB transplant by the New Year.

I have also moved all my "spare" gpu's to the Mining Rig. So it will being Weekend Warrior duty (in the near future) with an AMD 2700x and 3 gtx 1060's till I get another replacement gtx 1660 Super.

As long as I limit myself to one 24/7 multi-GPU system maybe I can afford this hobby.

Nahhhhh. Save up for a 3990WX.

Lets see now.
1) 3990WX, oodles of money.
2) sTR4 MB, more oodles of money.
3) Get a "good" TR4 liquid cooled cpu cooler, more, more oodles of money.

Grand Total: more, more, more oodles of money. I think I just shot my Christmas, New Years, Valentines Day, July4 and BD money and I still have to take out a loan.... :)

I am beginning to suspect that a previous generation EYPC (used) with 32 cores might actually be cheaper (and slower) than that 3990WX.
Or that a 16 core/32 thread EYPC (used) is cheaper than a 3950x (at current prices).

I signed up for one of those "in stock" notifiers and now I am getting hit daily with an email for an "in stock" AMD 3950x.

I too signed up for a notifier and kept getting constant notices of availability, yet when all the links were clicked, the product was not in stock.

I just happened to visit my bookmarked page for the 3950X and found it in stock and ordered it. At MSRP. Put it in yesterday afternoon. Now of course the host is dry of Seti and that was the only project I was running cpu work on.

The notifiers are useless in my opinion because the notices take so long to filter out through email that the product is gone long before you get the notice.

@Keith,
I think you experimented with a Linux AVX CPU application on your Amd 3900x?

And I think you noted it ran "hotter". Did it process faster? And where/what is it?

Tom

A proud member of the OFA (Old Farts Association).

Yes, it is 3% faster on a majority of tasks. And yes it runs hotter because it is doing more work in a shorter period of time. Answered in your PM.

More heat implies it is also using more power too. I will have to think about if 3% more production is worth the higher power bill :(

No that is incorrect. Power is a function of energy delivered over time. If the wattage goes up but the time duration goes down, the power used is the same.

eBay sent me and everyone else who was watching an Amd 3900x an offer to let it go for $465. It made my teeth hurt but where would I put it? In a part-time rig or a Windows box.....

Darn, that is a good deal. Much better than the MSRP of Amazon or the $30 markup that Newegg.com sells it for. That is about the price I paid for mine at Amazon after the Amazon bucks reward was applied.

True.

I think you meant to write "energy" is the same.

True. What I was trying to get across to Tom is that the kwh used for crunching is either going to be the same or maybe less depending on how much faster the AVX2 app is. He is most concerned on how much crunching is going to cost him. He has been reducing hosts and shutting them down to get a more palatable energy bill.

I would be willing to pay list for an AMD 3950x. But I would be replacing a 3900x for a net gain of 8 in capacity but like most everyone I run at 90% or so of the available threads. So it is not that much of a gain... But then I AM subject to CORE ENVY.

Oh, well.

Tom
ps. Just got done setting up an alert for $500 - $800 "buy it now" for a 3950x on eBay. Now I have an automated way to catch the likely (eventual) price decline.

---

A proud member of the OFA (Old Farts Association).

My price alerts netted me nothing but disappointment. I just accidentally landed on the Amazon page for the 3950X and found it in stock. Instant click. Don't think my trigger finger was ever faster.
I gained more than just 8 threads. I gained more clock speed and memory speed at less heat. My tasks per day is going up in BT so my RAC must be. But Zalster said our individual host stats have been frozen for a day or more now. No way to gauge right now.

Or maybe you just wait till next year & Zen3?

It's rumour time. Zen 3 is rumored to be flaunting monumental IPC gains in early testing.

As AMD confirmed at the HPC-AI Advisory Council UK conference, their next-generation server architecture, Milan, is being tested by their biggest customers. Milan and Ryzen 4000 will share the same Zen 3 architecture and TSMC’s 7nm+ EUV process, meaning that most we hear about Milan applies to 2020’s Ryzen, too.

According to Red Gaming Tech and Bits n' Chips, a multitude of AMD’s customers have tested Zen 3 and all say the same thing. The new architecture’s redesigned floating-point units have increased IPC in scientific tasks by something close to 50%, while integer work has seen a 10-12% boost. The combination of the two has resulted in a ~17% or greater IPC increase in mixed workloads.
