Zen3 architecture uses SMT4 thread technology? ABut there is no official source of information about this rumor.
As multi-core and multi-threading technology has become the mainstream of desktop processors, the emphasis has been placed on improving CPU performance based on the number of threads. Many processors today feature single-core and multi-threaded technology. It is rumored that the Zen3 architecture will use SMT4 technology, which is a single-core four-thread, but AMD officials are very cautious.
According to AMD’s roadmap, the Zen3 architecture has been developed and TSMC’s 7nm EUV process is expected to be used for mass production in the second half of 2020. Earlier rumors have it that the Zen 3 architecture can support a single core with four threads, then a physical core can be used as four logical cores. We will see a configuration with 64 cores and 256 threads.
However, during the interview, AMD Senior Vice President and CTO Mark Papermaster said that AMD had not officially announced the adoption of SMT4 technology, indirectly denying the possibility of applying SMT4 technology to Zen3.
In his opinion, the nature of the SMT multi-threading technology to be used must be considered comprehensively – some applications may benefit from SMT multi-threading technology, others may not. Judging by current PC usage, many people do not really use SMT technology.
According to Mark Papermaster, SMT technology has been used in many areas, and SMT4 technology can benefit certain applications, but cannot be used in many other workloads. SMT4 technology has been around for a long time. The new concept of technology used in server products for some time (not just at the end of SMT4 technology) depends on the ability of certain workloads to benefit from it.
