Might be the next best contender for productivity per watt after the SoC devices like the Pi's and Nanos. I imagine you could keep the thermals under control with just air cooling.

True

Here in the Netherlands power is not cheap something like 0.23 / 0.25 euro Kwh.
So everything you can do to reduce power consumption will save you a lot of money

And spare a thought for the Isle of Man who have similar electricity prices to the Netherlands. Running my two Ryzens and the 2990 results in an annual bill of over £2000 GBP which is quite an overhead. Add a 3990 and I may need to remortgage!

Interesting speculative video over at the AdoredTV YT channel. Posits the reason why there is limited availability of 3900X parts and the delayed release of the 3950X part to November is because of demand for every good 8 core chiplet going to Epyc parts where demand is massive and more than was expected by a large margin. Absolutely no reason to sell two 8 core chiplets as a 3950X part when they could be used in a $7000 Epyc cpu.

I agree with every point made in the video with sound reasoning. So I do not expect the 3950X to be anything more than a paper launch in November. Will not have any availability on that part either. The defective dies in the 3900X part are the bottom of the barrel performing dies coming off the wafer. Everything else is going directly to Epyc. And the reason that the TR3 part is only going to be 24 cores. Again the bottom of the barrel dies are going into that cpu. And I also agree the 3950X will not sell at its original $750 MSRP. Try $999.

Another point brought up is the decision by Global Foundries to stop their 7nm ramp up. Very bad business decision in my opinion. The demand for 7nm from all sectors is outstripping supply by massive amounts.

Agreed bad decision making from Globalfoundries. I mean AMD could no predict how popular the new AMD am4,tr and epyc's are at the moment.

No, I just need to run the A/C all year round at $0.53 KW/hr cost for power.

Global foundries weren't on AMDs roadmap for initial 7nm products
Keep in mind that AMD’s first 7 nm product was designed for TSMC’s CLN7FF from the beginning,
and it was for business reasons they dropped their own 7nm development.
First. If GlobalFoundries kicks off production using the 1st Gen 7 nm fabrication process, it would have needed to cure all of its teething troubles and offer its clients a roadmap forward. The latter would have included 2nd Gen and 3rd Gen 7 nm, but nothing stops there. Customers would have asked for 5 nm and then for 3 nm nodes. Meanwhile, you cannot tell your clients that you are packing up after a certain node and then hope that this node will be a success (the same is true for DUV-only 1st Gen 7 nm).

Second. Development of leading-edge process technologies is extremely expensive. Every new node requires billions of dollars in investments. Those costs are eventually amortized over each chip the company makes, so to keep increasing R&D costs from driving up chip prices, foundries need to produce more chips. To make more chips, they need to either run multiple fabs that use the same process technology (these are going to cost $10+ billion in the EUV era), or build giant fabs that process a gargantuan number of wafers (these are going to cost $20+ billion in the EUV era). Meanwhile, GlobalFoundries has only one leading-edge fab featuring capacity of 60,000 wafer starts per month. As a result, either GlobalFoundries has to pass these R&D costs on to the finite number of wafers it processes – and become uncompetitive against rivals in the process – or eat the costs with reduced profitability.

Meanwhile, having spent well over $20 billion on GlobalFoundries over the last 10 years, Mubadala, the owner of the company, is not inclined to lose more money or invest tens of billions in the hopes of becoming profitable one day. The investor wants GlobalFoundries to stop bleeding and start generating profits.


...While it is sad to see GlobalFoundries leaving the ‘bleeding edge’ field, it is evident that the company’s odds against Samsung and TSMC were not high enough for the owner and the management to take the risks. Therefore, it looks like ‘scaling out’ by offering a set of specialized (and maybe even unique) process technologies instead of ‘scaling up’ and offer another ‘bleeding edge’ node might just be a better bet for GlobalFoundries.

I saw that article back in August too. Still think they have a hard row to hoe to become profitable even at 14/12nm. I don't think they will get enough wafer starts from new customers. Time will tell.

i notice almost all the wu i get on my TR pc is vlars. compared to the ryzn pc or even the old fx one.

Instead of "adding" a 3990x you could upgrade one of your Ryzens to the 3990. Might be able to delay the remortgage.... :)

Wendell over at Level1Techs posted an interesting video benchmarking and commenting on "Threadripper LIte" that he postulates the possible performance of the 24 core TR3 cpu coming in November. He tested a 1P Epyc 7402P cpu which has 24 cores also and only running at 3.35Ghz. But that is ALL CORES running at 3.35 Ghz. 256GB of 2666Mhz ECC memory. So the core clocks and memory much lower than what TR3 is probably going to use.

Looks like Intel finally has been forced to reduce their prices for their latest HEDT family processors to be more competitive with Threadripper 2000 and the upcoming Threadripper 3000 cpus.
https://pcper.com/2019/10/cascade-lake-x-price-leak/
Top of the line Cascade Lake-X 18/36 i9-10980XE cpu at half the price it was offered last family at the same core count Skylake-X Refresh i9-9980XE.

Great observation. They have been lamenting their lack of 14nm production capacity for the entire year.

That does badly suggest how grotesquely Intel has been price gouging the market for us all for so long...

Here's hoping they keep away from their old dirty tricks and vandalism of their past 'marketing' that last stifled AMD and everyone else...

I agree. I will never forgive Intel for their history of "dirty tricks".
Still galls me that they have never paid a single cent of the court ordered judgement to AMD for their marketing shenanigans of the past.

Since it uses 160W at 4.35GHz, I expect the 5.5GHz power requirements are in excess of 300W, hence the need for liquid Nitrogen to achieve that clock speed.
