AMD has completed design phase of its "Zen 3" architecture and rumors are already appearing about its details. This time,
Hardwareluxx has reported that AMD could bake a
four-way simultaneous multithreading technology in its Zen 3 core to enable more performance and boost parallel processing power of its
data center CPUs. Expected to arrive sometime in 2020, Zen 3 server CPUs, codenamed "MILAN", are expected to bring many architectural improvements and make use of TSMC's
7nm+ Extreme Ultra Violet lithography that brings as much as
20% increase in transistor density.
Perhaps the biggest change we could see is the addition o
f four-way SMT that should allow a CPU to have four virtual threads per core that will improve parallel processing power and enable data center users to run more virtual machines than ever before. Four-way SMT will theoretically boost performance by dividing micro-ops into four smaller groups so that each thread could execute part of the operation, thus making the execution time much shorter. This being only one application of four-way SMT, we can expect AMD to leverage this feature in a way that is most practical and brings the best performance possible.
EITA PORRA

Assim, como a própria matéria diz, não é como se fosse um breakthrough, a IBM oferece quatro e até oito threads por core físico há anos. A própria IBM ajudou a AMD na implementação do SMT no Ryzen, como foi apontado por um cara que comentou.
Entretanto, pro mercado doméstico não tem nada parecido.
