    16 cores and 32 threads of blistering performance. It made its competitor slice the prices in half.

    Have played with it for one month now, used PBO and manual overclocking, but stock speed suits my usage best. PBO adds just a few percent of performance, with a large increase of power consumption and heat. Manual overclock means no core boosts to 4.7GHz.

    Cinebench20 performance numbers: Stock: ~9260 (~3975MHz, 1,1V, 57°C). PBO: ~9660 (~4125MHz, 1.3V, 75°C). Manual OC: 10100 (average 4300MHz, 1,28V 75°C).

    Wow. Blazing fast. Blows my old 6700k out of the water; it's over 4x faster in cinebench.

    Runs a little hot from what I'm use to while idle (29-32 C). Under load it hits temps of 71-75 (71 C being the reported average). Use Ryzen Master to check temps, as other programs do not give accurate numbers.

    Very expensive CPU, and complete overkill for my needs, but its fast and apparently runs cooler than the 3900x. If you actually have a need for this many cores and can afford it and the supporting hardware, it will not disappoint.

    from completed build Sober black

    Also read my description about my build. It is just a premium silicon. I believe also I have won the the silicon lottery. At stock settings my benchmark results are way better than online reviewers but also I have never seen him reaching 60C at an ambient temperature of 21C. It is just a beast living happily and cool under noctua NH-D15 chromax. It hits frequently 4700 and little bit above for single thread and multi thread performance is a beast. Beats 2nd gen 24 core Threadripper and competes with 2nd gen 32 core part. It is a dream for 3d editing and simulation having this performance on a desktop mainstream platform.
