Uniko's Hardware managed to get its hands on a laptop with AMD's upcoming Ryzen 7 5800U. This APU uses the Zen 3 architecture, the official announcement from AMD is expected next week but actual product availability will happen a lot later.

VideoCardz has a nice writeup that sums up the results. Single-threaded performance is seen beating the Intel Core i9-10900K desktop flagship, but multithreaded performance is not that good. VideoCardz speculates the laptop may have had issues with SMT support so the multi-threaded scores may not be indicative of the final retail product:
In CPU-Z software, the CPU scored 592 points in a single-threaded benchmark and 3812 points in a multi-threaded workload. The multi-thread score may not be very impressive, but the single-thread score of 592 points puts this CPU even higher than the current mainstream desktop flagship from Intel, the Core i9-10900K, which scores 584 points (according to official CPU-Z charts).

When it comes to multi-threaded score, there clearly appears to be a problem with SMT. Even the Ryzen 7 4800U scores at 5K points, so it is safe to assume that either SMT does not work, or this particular notebook has a BIOS which is not yet fully supported.
The Ryzen 7 5800U is an eight-core, sixteen threaded model with a 2.0GHz base frequency and a 4.4GHz Boost.
