AMD Ryzen 9 3900: A 12-Core 65W CPU Listed

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’.

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 MattSlash3 - Thursday, September 26, 2019 - link
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).Spunjji - Friday, September 27, 2019 - link
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.NICOXIS - Thursday, September 26, 2019 - link

Could be cheaper as it won't have to bin as well.yannigr2 - Thursday, September 26, 2019 - link
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.Danvelopment - Friday, September 27, 2019 - link
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.
