Has anyone looked into the specs here, looks like a nice upgrade for some of you.

"AMD's Threadripper platform gave a hefty boost to the high-end desktop (HEDT) market: 16 cores and 32 threads using AMD's Zen architecture. Today, AMD announced the second generation of Threadripper: it's twice as big again, with up to 32 cores and 64 threads, and it uses the revised Zen+ core of the second-generation Ryzen chips."

"The flagship processor—the 32 core—will have four Ryzen die inside the package. Those are tied together with AMD's Infinity fabric that allows those four die to act like one monster processor working altogether," said AMD senior vice president and general manager of computing and graphics, Jim Anderson.

Some current X399 motherboards could struggle with Threadripper 2 when it comes to power delivery, though this might only mean more restrictive overclocking. However, we’ve seen refreshed X399 boards at Computex with improved power delivery capabilities (19-phase VRM) designed with Threadripper 2 and its many cores in mind.

In addition to Threadripper 2, AMD said a Radeon RX Vega 56 “nano” graphics card designed for Mini-ITX systems is now shipping. It also announced a new generation of Vega GPUs for workstations and datacenters based on the 7nm process and featuring four stacks of high-bandwidth memory (HBM2) totalling 32GB. It added that people should “stay tuned” for the 7nm consumer GPUs.

Pointless to look at specs now, as it essentially QS and final batches may be very different to (i.e. 3.0 base/3.4 boost are not final).

If it is Mining monero 7 it needs a big cache

If you're looking to build a gaming PC that could be used for mining while you aren't using it, then this could be for you. However, if you are solely at it just to profit from mining, then this CPU would probably be a bad idea. GPU-mining is coming to an end, much more CPU mining. Invest wisely, do the math, don't just be blinded by the specs.

Well since monero has promised to fork against asics.  This cpu could be okay

Along with the m.2 fpga accelerator and one Vega gpu

Gotta love Monero's dedication to CPU mining!

Yeah I have an 1800x it makes 60 cents a day and burns 30 cents to do it.

So 30 cents a day while it mines with 2 1080x

I am keenly interested in upgrading to a Threadripper 2 for my main desktop, so I'm watching for specifications and pricing very closely. I almost upgraded to a Threadripper 1 setup last summer, but the high RAM prices put me off at the time. Sadly RAM is even more expensive now, but depending on final specs/prices I may go for one.  I don't think I would buy it just to mine, but I sure would mine with it when I'm not using it for other things.  I expect it could pay for itself in a year easily that way.

I guess philipma's electricity cost is cheap but how do normal people figure CPU mining with these threadripper is profitable? It seems to consume much more electricity compared to GPUs. As far as i remember the 1900x threadripper mines 1k h/s cryptonight while cosuming above 200 watts. Seems like you can't compare that to a Vega56 that can do 1.8k h/s while only consuming 160-180 watts.

rig is fully roi'd

edit  I check rig

here are stats  mining with 2 gpus  I pull 505 watts on kill- a-  watt meter

I am doing 2 1080tis.

no cpu mining with the ryzen 1800x

power up  the cpu mine monero 7

watts jump to 555

505 = 12.12 kwatts a day

555 = 13.32 kwatts a day  

at 10 cent I am   $1.21 a day  gpus only
at 10 cent I am   $1.33 a day   gpu + cpu

at 20 cent I am   $2.42 a day gpus only
at 20 cent I am   $2.66 a day gpus only

I earn  5 dollars with the gpu and 60 cents with the cpu.

worst case  is 60 cents - 24 cents = 36 cents  extra with cpu

best case is 60 cents - 12 cents = 48 cents extra with cpu

reality for me is maybe I gain 40 cents a day with that cpu.  that is paid off fully.

so for the 1800x  it is worth having.

my guess is the 2700x may be good.

thread ripper 2 is a long way off have to wait and see if it is worth it.


below was not accurate  I set a meter up and results above are good.

the 1800k pulls about 100 watts maxed  that is 2400 watts in a day  at 13 cents that is 13 x 2.4 =  31 cents a day. and I earn 60 so I net about 30 cents.

Why not take the 30 cent profit.

https://www.amd.com/en/products/cpu/amd-ryzen-7-1800x

the 2 gpus make  about 6 a day burning  350 watts.

so 6.60 earn  and  350 + 100 = 450 watts  that is 11 kwatts at 13 cents = 1.43 in power cost.

so this rig nets 6.60 - 1.43 = 5.17 usd a day.

How many pcie lanes will be supported?

I think the same like current x399, it's compatible with current X399 MB's.
But why not going on "Intel's 5Ghz-28 Core"? LOL only 3KW to run it :-).

It's nice to see that AMD R&D is working to produce the best computer processors, I think if they keep it like this for a couple years they will dominate the CPU world.

I'm not sure if it will make a difference when it comes to mining though. It will have high hash rates, no doubt, but it's going to be just shy of what a GPUs were already getting for a few years now. So, mining wouldn't be the best way to use it IMHO.

If it has a large enough cache it should beat a Vega for mining Cryptonight.  If it has enough cache to use 50% of it's threads it ought to do somewhere close to 2400 hashrate in XMR stak. That's based on 4 R7 1700X or 2700X hashrate since this is essentially 4 of those "glued" together via infinity fabric. I think the biggest issue that we just don't know yet is if it will have 4x the L3 cache or if it will be less. 

I thought we did know about the cache size.
Threadripper basic CCX has 4 cores and 8Mb L3 cache.
So 2Mb L3 per core.

Well if you can work out a way to run a GPU standalone and not need a CPU/MB/RAM etc.. then yeah a Vega56 takes 160-180W.
Or you do it correctly and factor in the system overhead per GPU, because the rest of the PC doesn't run for free.
I look at it this way, I have a 4x Vegas  running on a 8 core Xeon system. The whole system takes 800W from the wall mining. The only parts of that system that return any profit are the Vega GPUs. Therefore each Vega pays for 200w.
Now I can get the CPU to generate $1-$1.20 mining and the power is now 830W. So it seems to me the CPU only has to pay for 30W.

Baz

Lol, yes :)

I don't think it has been verified as far as what Threadripper 2 will have for the 32 Core 64 Thread CPU. If I had to guess I would say it's probably on the same scale of cache to core as the first generation Threadripper, but that would only be a guess on my part at this point.


The nice thing about buying a Threadripper (for me and many others too) is that you would buy it to use for other purposes (all sorts of CPU intensive work loads) and then mine with it the rest of the day.  Actually you could very easily mine with it and do any kind of basic desktop usage at the same time.  There would be a hashrate drop, but it's still not a bad way to go.

Yeah, I agree, having a larger cache will indeed increase the hash rates but I wonder if there will be enough cache or not.

I see there's an article here: http://www.legitreviews.com/mining-amd-ryzen-threadripper-1950x-processor-nicehash_202416 and the 16 core threadripper was getting 1.33 KH/s. So, if they just double the number of cores/cache then we should see 2.66 KH/s for it and like you said it would surpass the 1.8-2 KH/s hashing power delivered by the Vega GPU's.

Good news but I see the new trend in mining is using FPGAs. They will dwarf any CPU.

but    you will be using a mobo of some sort  to mine.  so having a top of the line cpu would allow  more flexibility.

Right now I am focusing on holding cash and coins more then any other thing.

Since we are "exploring" it is worth mentioning M2 slots along with these new-fangled huge-core-count CPUs making it into traditional desktop configurations.  M2 slots are beginning to function in tandem with GPU mining applications for BIG performance bursts so it stands to reason there could be similar tandem work to be done with CPUs.

Imagine a desktop with 2x 1180ti, 32-core CPU, and 2x M2 slots (one for the GPUs and one for the CPU)... sounds amazing, right?

Yeah .

 My thoughts would be 1 new thread ripper with a m2/fpga gpu booster and 2 1180ti gpus.

along with a 4tb ssd.

I was looking at motherboards for threadripper yesterday and you can get models with 4 PCIE x 16 slots and 3 M.2 slots.  If these mini FPGA type GPU accelerators prove to be the real deal I could see a beastly setup with one of these CPUs as the base. 

yeah but costly maybe 6k


 edit

I do have 14x 1080tis left
I have ram
I have psu
I have ssd

I would need a few of the m.2s I think 3 of the best are 900
a mobo ----------------------------------------------------- 300
a thread ripper 2 ------------------------------------------- 700?
                                                                           total 1900

4 1080ti's are 2800

so 4700

Well, a threadripper first gen 16 core is $900 (although you find a sale once in awhile for as low as $700).  I think the 32 core Threadripper 2 is going to be $1200 at launch, but I'd love to be wrong.

I think it really hinges on how much of a boost the fpga adapter thingies actually gives.  I could make use of a Threadripper in my main personal desktop/workstation, so I'm keeping a close eye on them even if it just means buying a first gen when they're doing a closeout sale somewhere.

Intel fires back:


"While the database entry lists the processor as “not being recognized,” the specs suggest this is the Core i9-9900K: 8 cores, 16 threads, and a Turbo clock of 5GHz. It’s also expected to come with 16 MB of L3 cache, a TDP of 95W, and an Intel UHD 620 graphics chip.

In 3DMark's Time Spy test, the CPU scores 10719 and 9862 overall. It achieved this using an Asus ROG Strix Z370-F Strix Gaming motherboard with 16GB of G.Skill DDR4-2666 memory, a 500GB Samsung 960 Evo SSD, and a GeForce GTX 1080 Ti graphics card. This does suggest the 8-core/16-thread chip is compatible with Z370 mobos—probably through a BIOS update—as well as the upcoming Z390 chipset, which might end up being a rebranded Z370.

Compared to the Ryzen 7 2700X (overclocked to 5GHz), the 9900K is way ahead of the AMD chip's score of 9387 points. Intel's own 6-core/12-thread i7 8700K is also lagging behind with 8935."

I have just bought a Threadripper 2950x. It is currently mining at 1350 hashrate at the most without any overclocking, which is exactly the same as what its previous generation 1950x can achieve.  So perhaps with a little more tweaking, it can be faster, but I would not expect too much from it.

 AMD Ryzen Threadripper 2950X 3.5GHz/32MB is able to use 16 threads while Monero mining. Each tread is 50-60 h/s. It must give up to 960 h/s. If you have better results it is more than enough.

Currently retailers seem to be getting rid of the 1950x stock they still have so there's a few good bargains out there. Since they are supposedly just as fast as the 2950x, at least for mining, one could think about building a rig or two with these bad boys just to make a few pennies on the side when mining something with the GPUs.

Yes. 2950X stays at that hashrate or a little lower when you surf the Internet and watch Youtube Videos
