The AMD Ryzen 9 3900X could easily beat Intel's latest 10th gen Core i9-10900K in the Corona Render Test benchmark finishing nearly four minutes earlier than the latter.

This is an indication that the upcoming Zen 3-based Ryzen 4000 CPUs with purported higher IPC can further dent prospects of Intel's Comet Lake-S and Rocket Lake-S offerings.
