AMD 'Zen 4' 2021 Start på banen som TSMC optimistisk ca. 5 nm



AMD's 'Zen 4' CPU microarchitecture is on track for a 2021 launch as its principal foundry partner, TSMC, is optimistic about early yields of its 5 nm silicon fabrication node. TSMC supports the 5 nm product roadmaps of not just AMD, but also Apple and HiSilicon. 'Zen 4' is particularly important for AMD, as it will release its next enterprise platform, codenamed 'Genoa,' along with the new SP5 socket. The new socket will present AMD with the opportunity to significantly change the processor's I/O, such as support for a new memory standard, a new PCIe generation, more memory channels, more PCIe lanes, etc. As early as 2019, the foundry is seeing yields of over 50 percent for the 5 nm node (possibly risk production designed to test the node), which is very encouraging for its customers.

AMDs køreplan for 2020 ser introduktionen af ​​'Zen 3' på 7 nm EUV-processen (kaldet 7 nm +). AMD kommenterede for nylig, at ydeevnen i 'Zen 3' versus 'Zen 2' vil være 'helt i tråd med hvad du ville forvente af en helt ny arkitektur.' EU-noden på 7 nm giver en markant stigning på 20 procent i transistortæthed sammenlignet med den nuværende 7 nm DUV-knude 'Zen 2' -chipletter og virksomhedens 'Navi'-familie af GPU'er er bygget på. 'Zen 3' kunne se virksomheden slippe af med CCX (quad-core CPU-kompleks) og fremstille chipletter til monolitiske blokke af CPU-kerner uden underinddelinger. For klientsegmentet er 5 et tilbagevendende nummer i 2021. Det vil se introduktionen af ​​5. generation Ryzen-processorer (5000-serien), bygget på 5 nm-processen, der understøtter DDR5-hukommelse, PCI-Express gen 5 og ny AM5 klientsegment CPU-stik.
