AMD has been working hard to prepare its next-generation Ryzen 4000 CPUs codenamed Vermeer, and we have some exciting news about it. Thanks to the sources over at Igor's Lab, we have information that AMD Vermeer CPUs are close to launching. Apparently, the CPUs have are now at B0 stepping and are going through the usual validation process. The B0 stepping is where the CPU is fully working and now it just needs to go on mass production. The next step for the CPU is high-volume manufacturing and in a very quick time, the CPUs will be ready to hit the market.

Usually, it takes 3-4 months for silicon to be manufactured, so if AMD has orders set at TSMC's factory for the manufacturing of its processors, we could get the processors very soon. Given that AMD is ready with the design, and there is a lack of competition from team blue, AMD is very flexible with timing. The processors can be ready whenever AMD needs them to be. After a while, AMD is in a position to dictate the market needs and tailor them to their own. This used to be a position where Intel was before the Ryzen era. Now if AMD needs to do a launch as quickly as possible they can. If not, they have the design ready and can push it a few months.
 
Some more good news for AMD in my opinion

Don't pull a big-Blue and delay roll out because there's no competition...

AMD doing its best to help out Intel with their never-ending supply shortages!
