An entry of AMD's Flagship Ryzen 5000 Desktop CPU, the Ryzen 9 5950X, has been spotted within the Geekbench benchmark database which shows an insane clock speed and performance figures. The entry was spotted by TUM_APISAK (via Videocardz) and shows the 16 core chip running at up to 6 GHz.

What's surprising about this overclock is that it was achieved in the Apple macOS environment which is unusual for an overclocked entry of an unreleased chip to appear, that too that with LN2 cooling. It's likely that the setup was a Hackintosh and booted up with macOS 10.15.7 (Built 19H2) operating system however the benchmark title is mentioned as iMac Pro which makes it seem very unlikely.
