As we saw in a related article and used to rumor that in those months it was around the world, AMD might be working on improving its construction to double the number of threads each made physically.
This is something that IBM has taken to extremes and that Intel hasn't thought much of it today, and as back then, new rumors and leaks point to this development, which is about to go into Zen 4.
A better scale with each SMT is to maximize the performance of each thread
Today we know where those rumors about the implementation of this Zen infrastructure upgrade came from. Obviously, the classic AMD roadmap clarifies several exciting details that we now know won't, but at the same time show some improvement We know they will eventually come.
Back then, as the slide shows, Zen 3 was being discussed as a possible development involving such improvements and although nothing else was explained, we can understand the reason for these claims.
Slide shows at least two errors, Zen 3 and 7nm +. We already know that Genoa as the main construction will come under Zen 4 at 5 nm with TSMC ISL5 socks with DDR5 and PCIe 5 back in 2022. So the slide should be very old and AMD didn't think at the time that TSMC could press as high a speed as its developer team.
64 cores will be taken care of, but with four threads each (SMT 4)
It is not yet clear whether AMD will maintain the maximum number of calls at 64 even though it has 5 nm, representing another gensity in density and frequency. It can be seen from a performance point of view, and that is that Intel or AMD did not skip the SMT 4 precisely because of the energy loss it takes to drive it at high speeds.
Keeping the number of cores doubled by the number of threads while maintaining usage may be another possible way to wait for a decrease in the lithographic process, since we can forget that both DDR5 and PCIe 5.0 will require a very large number of pins in that thread. .
As such, take this information with tweezers as of now, since we can only know that Zen 4 will arrive at 5 nm that day and consequently coincide with the introduction of DDR5 and PCIe 5.0, with the exception of Gen-Z.
Let's not forget that when we share the build with desktop processors, when the SMT 4 reaches Genoa, it should also come to the average user with the Ryzen 5000, something that wouldn't make much sense, since what AMD needs is more competition with Intel. in gaming, because multicore is one step ahead.
