Since the multi-core and multi-threaded technology has become the mainstream of desktop processors, how to improve the performance of the CPU depends on the number of threads. Now many processors are equipped with single core and dual threads technology. It is said that the zen3 architecture will use smt4 technology, that is, single core and four threads. However, amd officials are very cautious about this.

According to AMD's Roadmap, zen3 architecture has been developed, and it is expected to use TSMC's 7Nm EUV process for formal mass production in the second half of 2020.It's said that Zen 3 architecture can support single core and four threads,Then a physical core can be used as four logical cores. We will see the configuration of 64 core and 256 threads

However, mark papermaster, senior vice president and CTO of AMD, said in an interview recently that AMD had not announced the announcement about smt4 technology, which indirectly denied the possibility of smt4 technology application in zen3.


According to him, what kind of SMT multithreading technology needs to be considered comprehensively

Mark papermaster said that SMT technology has been applied in many fields, smt4 technology can benefit from some applications, but many other workloads cannot be deployed,Smt4 technology has existed for a long time. It is not a new technology concept. It has been applied in server products for a long time. It depends on whether some workloads can use it.
