Once again, thanks to Pat Schur, we have a basic idea of the specifications of AMD’s yet unannounced Ryzen 7 5700X and the Ryzen 9 5850X/5900 CPUs. As expected, the former is an octa-core chip while the latter is a twelve-core part, both featuring a TDP of just 65W. The 5700X will be based on one eight-core CCX with 32MB of L3 cache and 4MB of L2 cache per core while the 5900/5850X will be a dual-CCX part with 64MB of L3 cache and 6MB of L2 cache per core.
The reason why these parts weren’t announced along with the other Ryzen 5000 CPUs is cos the profit margins are lower, and constrained 7nm capacity paired with a lack of competition from Intel meant prioritizing the best performing chips. We should see both these parts as well as the Ryzen 5 5600 in Q1/Q2 2021, right alongside the Rocket Lake-S processors from Intel.
