AMD 'Zen 4' 2021 lansiral na progo kot TSMC Optimistic približno 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.

AMD-jev načrt za leto 2020 uvaja „Zen 3“ v 7 nm proces EUV (poimenovan 7 nm +). AMD je nedavno komentiral, da bo dvig zmogljivosti 'Zen 3' v primerjavi z 'Zen 2' 'v skladu s tistim, kar bi pričakovali od povsem nove arhitekture.' 7 nm vozlišče EUV zagotavlja znatno 20-odstotno povečanje gostote tranzistorjev v primerjavi s sedanjo 7 nm DUV vozlišče 'Zen 2' čipletov in družino 'Navi' družine GPU-jev. Z Zen 3 lahko podjetje odpravi CCX (štirijedrni procesorski kompleks) in izdela monolitne bloke jeder CPU brez poddelitev. Za odjemalskega segmenta je 5 ponavljajoča se številka leta 2021. V njem bodo predstavljeni procesorji Ryzen 5. generacije (serija 5000), zgrajeni na 5 nm postopku, ki podpirajo pomnilnik DDR5, PCI-Express gen 5 in nova vtičnica CPU za odjemalca AM5.
