For Zen3, we don't know exactly what changes it has made yet, but a few days ago it was reported that the Zen3 architecture is expected to support four threads, that is, four threads.On the basis of 1C/2T, it becomes 1C/4T. A core is equivalent to four threads, which greatly improves the multi-threading capability.。
Four-threading technology has been used on IBM Powerprocessor for a long time, right?The serverCPU still makes sense, butThe rumor that Zen3 uses four threads is not credible in itselfBecause from the information given by AMD, the Zen3 architecture uses 7nm process, mainly adding EUV lithography process.
According to TMSC, compared with 7nm process, 7nm EUV process improves performance by 10%, energy efficiency by 15% and transistor density by 20%. This increase is not the level of a new generation of processes, or an improved optimized version.
In this case, it is unlikely that the Zen3 processor will use four threads, and AMD will not dramatically change the architecture of Zen3.
In reality, at 7Nm Zen2,AMD has realized 32 threads of desktop 16 cores and 128 threads of server 64 cores.So many cores are enough to take the lead. There is no need to continue the number of cores / threads. There are really four threads that will not be put on Zen3. It is more likely that they will be put on the Zen4 and Zen5 architectures with the great changes in architecture, technology and slots.
According to the latest explosion, the Zen3 processor of the 7 nm process will maintain the basic structure unchanged, but the energy efficiency is optimized, the production cost is reduced, the yield is increased, and the overall performance is more similar to that of the 14 nm Zen to 12 nm Zen architecture.
