AMD still has got a few surprises left for the desktop Ryzen 3000 series, we expect the 3500, the 3950X but as it seems a Ryzen 9 3900 is inbound as well, that part would be pretty amazing at it would over 12 cores / 24 threads with a base-clock of 3.1 GHz and only a 65 Watt TDP.
It was motherboard manufacturer Biostar that spilled the beans, as it referenced the Ryzen 9 3900 as motherboard compatible. It is assumed the boost clock is 4.2 GHz for this part. The base clock is 700 MHz lower than that of the Ryzen 9 3900X in order to match that TDP of 65 watts.
The processor already turned up in a Ryzen Pro model, but now as well in some benchmarks and set an overclocking record even. Toms hardware reported that overclocker Allen "Splave" Golibersuch overclocked a non-official AMD Ryzen 9 3900, and with he help of liquid nitrogen reached an impressive 5.5 GHz. With 4,319 points Cinebench doesn't look bad either, Geekbench 3 was enough for 6,924 points in the single-core score and 77,106 points in the multi-core score.
With a Enermax Liqtech II AiO liquid cooling Golibersuch reached 4.35 GHz on all cores at a voltage of 1.375 volts, which showed 3,420 points in the Cinebench R15. Unknown still remains what the processor will cost and when it will appear.
