BIOSTAR Lists unannounced AMD Ryzen 9 3900 Processor

AMD released their Zen 2-based Ryzen 3000 processors in July this year, and they instantly became a smash hit with gamers, due to their solid performance, and good pricing. The company's flagship processor at this time is the Ryzen 9 3900X, priced at $500, featuring 12-cores/24-threads, with clocks reaching up to 4.6 GHz. Now BIOSTAR has posted an update to their motherboard CPU support list, which mentions a previously unannounced "Ryzen 9 3900", without the "X", running at 3.1 GHz base clock and having a TDP of 65 W (the 3900X has 105 W TDP).

It looks like the Ryzen 9 3900 non-X is a more power-efficient version of the 3900X with lower clocks. It's possible that it is made from chips that failed the clock-frequency certification for the 4.6 GHz boost clock of the 3900X, but that work fine otherwise. By dialing down the TDP of their chip, AMD could also build an interesting SKU for OEMs, that want to market the high core counts, but aren't willing to drive up the cost of their power and cooling setup.

This 3900 Ryzen seems to be a nice alternative. I wonder what would be the max boost clock. Anyway what does it mean when AMD releases something like 3900 non X version. It seems logical since we have other Ryzen processors like that but I keep thinking.

I hope it's a fair bit cheaper, 65W is certainly optimistic though.

I assume the boost clock is 4Ghz max and so the 65W apparently. Voltage lower as well it adds up.

This is a smart move, make a lower TDP 12-core that's more affordable for people that want to make smaller systems or are looking for productivity but with efficiency.

optimistic ?
not at all!
105W is 4050 mhz allcore so 3.1 is definitely within 65W!

I've set 65W limit plus 88W limit for PPT(same as for 3700x) on my 3900x ant it hit 3600-3630mhz all cores while C15

Grain of salt at this rate, this is biostar after all. They haven't been a serious contender since socket AM2
