A motherboard maker has added support for AMD’s yet-to-be-announced Ryzen 9 3900 CPU. The product will be one of the industry’s first 12-core CPU featuring a mainstream TDP of 65 W. In addition, the same manufacturer revealed that there is a Pro version of the said CPU incoming.

Biostar’s X470NH motherboard recently gained support for AMD’s yet-to-be-announced Ryzen 9 3900 CPU with a 65 W TDP, which may indicate that the launch of the unit is imminent. This is not the first time an unannounced CPU has been listed in a CPU validation list. As a second source, the processor was listed in Eurasian Economic Union’s index of crypto-capable devices as a ‘twelve-core microprocessor’.

Ryzen 9 3950X 16C 32T 3.5 4.7 8 MB 64 MB 16+4+4 105W Nov. 2019 $749
Ryzen 9 3900X 12C 24T 3.8 4.6 6 MB 64 MB 16+4+4 105W July 2019 $499
Ryzen 9 3900 12C 24T 3.1 4.2? 6 MB 64 MB 16+4+4 65W ? ?

Based on the information provided by the sources, AMD’s Ryzen 9 3900 is a 12-core CPU with SMT that operates at 3.1 GHz default frequency (and presumably featuring a 4.2 GHz maximum turbo frequency from a 3DMark listing) and a 65 W TDP. The relatively low thermal envelope makes the Ryzen 9 3900 compatible with mainstream motherboards and cooling systems and enables PC makers to build relatively small computers featuring a 12-core processor. Meanwhile, the Ryzen 9 Pro 3900 adds various security technologies, enterprise management, and reliability enhancements for business and corporate computers.

It is unclear when exactly AMD plans to introduce its 12-core Ryzen 9 3900 and Ryzen 9 Pro 3900 processors and how much will they cost, yet it is reasonable to think that both products will be available in the near future.

    It is disgraceful. You could have bought Intel's 7nm $500 PCIE 4 12 core 3 months ago and been so much better off.

    Seriously tho - AMD has not lost sales over the delay - in the sense that intel has no substitute.

    This is my dream...

    Had no issue purchasing my 3900x up here in Canada

    I think AMD is just showing off at this point. This could very well be replacing my 3700X in my desktop, (not that the 3700X isn't adequate, but having 24 Threads in a 65W envelope at the height of Zen2's efficiency sweetspot would be just too tempting). I wonder if it would maintain similar boost clock speeds to 3700X in lightly threaded workloads (I.e gaming), but only drop to lower speeds when all threads are loaded up. Either way, the performance per watt will no doubt be higher than the already impressive 3700X, as processors tend to be more efficienct with wider and slower approaches. Very much welcomed for my overnight video render projects and WCG.

    I keep saying I won't upgrade my 2700X SFF build until a new socket is announced, but damn if AMD isn't making it increasingly tempting with SKUs like this one.

    AMD keeping the socket and motherboard compatibility is a great thing!

    You could say they have added a lot of fun for enthusiasts - a kick ass power upgrade & onsell is as doable as a treat in the same league as a decent dinner for two.

    A whimsical facet of it imo, is it works as a pyramid scheme - each onsell situation creates a salesman for another am4 platform to join the AMD ecosystem.

    Yeah... very sensible product. It does not try to get those high boos frequences when Ryzen sweet spot seems to be 4.2GHz, so this is almost as fast as 3900x (like 3600 vs 3600x) so it will offer much better value than 3900x that very rarely meet those very high speeds.
    We just have to hope that we Also get 3950 that have those 3.1 to 4.2 speeds. It Would be much better that upcoming 3950x cpus!

    A 16-core with 65W TDP would likely be the pinnacle of the AM4 Zen2 performance per watt overall. I'd dig that chip. Theoretically should be able to still do 4 GHz+ on =< 8 core loads, just like the 3700X does, so gaming won't suffer a lot.
