AMD Zen 3: SMT4 – 4 threads per core? Possibly for EPYC

Rumors about SMT4 for Zen 3 have circulated for quite some time, but they've never been confirmed. That's why we've avoided covering this topic until now.

However, the situation has changed. Zen 2 is out, and leaks about its successor are now appearing more frequently, their numbers rapidly growing each day.

One of these leaks specifically concerns four-thread processing per core in Zen 3-based processors.

While this is a plausible scenario for AMD's architectural development, don't expect this technology in the desktop segment. At best, simultaneous four-thread processing might appear in Ryzen Threadripper 4000, and even that's an extremely optimistic forecast. More realistically, SMT4 will remain exclusive to EPYC server processors for the foreseeable future.

Moreover, in the server segment, this technology could literally revolutionize the x86 server processor market.

Incidentally, AMD isn't the first company to implement such a technology in CPUs. An analogous feature has long been used in IBM Power processors, which support up to eight execution threads per core.

Given the stagnation in manufacturing processes, implementing such technologies is arguably the only way to boost performance without significant costs.

Stay tuned to our news for the latest information on Zen 3.
