AMD's Ryzen 4000 Desktop CPUs codenamed Vermeer and based on the Zen 3 core architecture might feature a few new flavors as reported by 1usmus. Famously known for his DRAM Calculator for Ryzen and his recent ClockTuner utility, 1usmus has revealed some interesting new details for AMD's next-generation Zen 3 based desktop processors.

According to 1usmus, AMD is working on a 10 core SKU for its Zen 3 based Ryzen 4000 family. He reports that the information is confirmed within the new AGESA 1.0.8.1 firmware and that at least one Ryzen 4000 CPU with 10 cores is confirmed to be featured in the lineup. This is an interesting choice since the 10 core AMD SKU will directly tackle Intel's 10 core CPU, the Core i9-10900K. AMD seems to be confident enough with Zen 3 to take on Intel's flagship Comet Lake-S part & showing them how their cores match up to Intel's older 14nm architecture.
