While AMD is still hard at work tweaking and refining its flagship 16 core Ryzen 9 3950X to get it ready for prime time in two months time, the company has reportedly completed the design of its next generation Zen 3 core microarchitecture, and it packs one hell of a surprise.

Rumor has it, that AMD’s next generation CPU microarchitecture is going to have a brand new feature called SMT4, and as the name implies it’s a simultaneous multi-threading feature. Whilst the company’s Zen 2 core does improve on the SMT capability of the original Zen architecture, which was the company’s first ever design to feature SMT, Zen 3 is said to make a giant leap forward by doubling the execution thread count per core from two to four.
