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 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.

    Thanks for the info Matt

    Not bad! I'd love to see a site do an in depth test of power curve efficiency on these chips (I may have missed one if it exists, it's been a hectic summer).

    Tidy! It'll be interesting to see whether they specify a tighter voltage curve to hit slightly higher speeds on the 3900 at that TDP, or just hard-code the lower TDP and let the CPU sort itself out.

    Could be cheaper as it won't have to bin as well.

    I think this model and a 3950 non X could help with the lower availability of 3900X and the delay of 3950X. Many want those models for their number of cores/threads, not specifically for their boost speeds and they would be probably more than happy with a somewhat lower speed, lower wattage model that will be available now.

    I haven't owned an AMD since my Phenom II X2 but looking forward to setting up my new server with an R5 when I'm close to release. Current server is an E3-1275 v3 (just switched my main workstation from an E5-2670 to an E3-1230 v5).

    It's pretty cool that I can buy an R5 now, then upgrade to a 16 core later without having to redo the whole machine when my project releases.

    If I ever need more than that, money will no longer be an object.

    Oh Dog. This is just stupid. I'd rather have 3800x.
