8-core AMD Ryzen 4000 Renoir desktop APU on ASRock B550 Taichi motherboard spotted on UserBenchmark performing on par with the Ryzen 7 4800H

An AMD engineering sample with the name “100-000000149-40_40/30_Y” has been found by Tum Apisak on UserBenchmark. The interesting entry reveals that this chip has 8 cores and 16 threads, and it records a base clock of 3.0 GHz and boosts to an average of 3.95 GHz. The sample was tested in combination with an AM4 socket-compatible motherboard in the form of the ASRock B550 Taichi. The B550 boards, which are scheduled for availability on June 16, will offer CPU support for both Zen 2 and Zen 3 processors.

The complicatedly named engineering sample is revealed by another source to be RenoirAM4, which means it seems to be a Ryzen 4000 desktop APU being tested here. AMD fans looking for a new desktop APU will be delighted that Team Red has stepped up the core count for this particular type of part, as the previous generation of desktop APUs maxed out at four cores. The apparent Renoir desktop APU managed an average bench of 86.2% in its UserBenchmark run.

The scores and average bench of the single Ryzen 4000 desktop APU engineering sample put it in the same ballpark as the AMD Ryzen 7 4800H’s performance, at least in this particular synthetic benchmark. The Renoir mobile APU’s average bench score is 86.1% (based on 166 tests at the time of writing), which is just below the desktop engineering sample’s mark of 86.2%. The 8-core AMD Renoir sample actually manages a strong 1-core score too, which should please gamers.
