It looks like AMD has a 5GHz Ryzen 5000 series CPU on the Horizon

The larger of these two processors, the 16-core 100-000000059-60_50/34_Y, reportedly features the same base frequency as the Ryzen 9 5950X (3.4GHz) and a boost clock of 5GHz. This may only be a minor performance improvement over today’s 5950X, but it is enough for AMD to market their processor as a 5GHz model, which is a big step for AMD’s Ryzen lineup.

Additionally, there is a new 6-core model with the OPN number 100-000000065-06_46/37_Y. This model features the same base/boost clock speeds as AMD’s Ryzen 5 5600X, making this model a B2 replacement, not an enhanced 6-core Ryzen 5000 series CPU model. 

B2 Stepping for Vermeer?! ????

100-000000059-60_50/34_Y
3.4 GHz (up to 5 GHz)
Stepping: B2
Cores: 16

100-000000065-06_46/37_Y
3.7 GHz (up to 4.6 GHz)
Stepping: B2
Cores: 6

At this time, it is unknown how AMD would market their enhanced 16-core model, as a 100MHz upgrade is minor at best. That said, a +100MHz boost could represent a larger increase in all-core boost clock speeds. Could this be AMD’s RX 5950XT? 
 
AMD’s Ryzen 5000 series CPU lineup has several gaps, lacking Ryzen 5 5600 (Non-X) and Ryzen 7 5700X models. These gaps prevent AMD from offering higher-value 6-core and 8-core models that feature that latest (Zen 3) CPU architecture. As it stands, AMD is competing with Intel’s budget-friendly i5 products with last-generation Ryzen 3000 series CPU models, giving Intel an edge in the budget CPU market. 

Rumour has it that AMD is releasing refreshed X570 motherboards, new designs that boast an enhanced X570 chipset that can operate passively. The launch of new X570S series motherboards presents AMD with a great opportunity to launch new processors, with a 5GHz Ryzen 9 model being an excellent centrepiece for AMD’s marketing efforts.
