AMD rudert zur체ck: Zen 3 doch auch auf 채lteren Mainboards

Bei der Ank체n짯di짯gung des kom짯men짯den B550-Chip짯sat짯zes hat짯te AMD ver짯lau짯ten las짯sen, Zen-3-Pro짯zes짯so짯ren nur noch mit Chip짯s채t짯zen ab Serie 500 zu unter짯st체t짯zen. Dies hat wohl zu eini짯ger Auf짯re짯gung gef체hrt, da AMD ja beim Sockel AM4 blei짯ben wird und damit zumin짯dest phy짯sisch nichts dage짯gen spre짯chen soll짯te, Zen 3 zu nutzen.

Nun hat AMD wohl auf den 철ffent짯li짯chen Druck reagiert und ein State짯ment ver짯철f짯fent짯licht. Man wer짯de Main짯board-Her짯stel짯ler auch f체r die Seri짯en B450 und X470 mit Zen 3 BIOS-Code ver짯sor짯gen. Daf체r m체ss짯te aller짯dings der Sup짯port f체r bestehen짯de Ryzen-Seri짯en ent짯fernt wer짯den, da der BIOS-Chip nicht gen체짯gend Kapa짯zi짯t채t hat, um alle Zen-Gene짯ra짯tio짯nen zu unter짯st체t짯zen. Daher soll ein ent짯spre짯chen짯des BIOS nicht frei ver짯f체g짯bar sein, son짯dern nur an Kun짯den her짯aus짯ge짯ge짯ben wer짯den, die nach짯wei짯sen k철n짯nen, dass sie einen Zen 3 auf einem B450/X470 ein짯set짯zen wol짯len, damit sich Anwen짯der nicht ver짯se짯hent짯lich der Unter짯st체t짯zung ihres alten Zen-Pro짯zes짯sors berauben.

As we head into our upco짯ming 쏾en 3 archi짯tec짯tu짯re, the짯re are con짯sidera짯ble tech짯ni짯cal chal짯lenges that face a CPU socket as long-lived as AMD Socket AM4. For exam짯p짯le, we recent짯ly announ짯ced that we would not sup짯port 쏾en 3 on AMD 400 Series mother짯boards due to serious cons짯traints in SPI ROM capa짯ci짯ties in most of the AMD 400 Series mother짯boards. This is not the first time a tech짯ni짯cal hurd짯le has come up with Socket AM4 given the lon짯ge짯vi짯ty of this socket, but it is the first time our enthu짯si짯asts have faced such a hurdle.

Over the past week, we clo짯se짯ly review짯ed your feed짯back on that news: we wat짯ched every video, read every com짯ment and saw every Tweet. We hear that many of you hoped a lon짯ger upgrade path. We hear your hope that AMD B450 and X470 chip짯sets would car짯ry you into the 쏾en 3 era.

Our expe짯ri짯ence has been that lar짯ge-sca짯le BIOS upgrades can be dif짯fi짯cult and con짯fu짯sing espe짯ci짯al짯ly as pro짯ces짯sors come on and off the sup짯port lists. As the com짯mu짯ni짯ty of Socket AM4 cus짯to짯mers has grown over the past three years, our inten짯ti짯on was to take a path for짯ward that pro짯vi짯des the safest upgrade expe짯ri짯ence for the lar짯gest num짯ber of users. Howe짯ver, we hear you loud and clear when you tell us you would like to see B450 or X470 boards exten짯ded to the next gene짯ra짯ti짯on 쏾en 3 products.

As the team weig짯hed your feed짯back against the tech짯ni짯cal chal짯lenges we face, we deci짯ded to chan짯ge cour짯se. As a result, we will enable an upgrade path for B450 and X470 cus짯to짯mers that adds sup짯port for next-gen AMD Ryzen꽓 Pro짯ces짯sors with the 쏾en 3 archi짯tec짯tu짯re. This decis짯i짯on is very fresh, but here is a first look at how the upgrade path is expec짯ted to work for cus짯to짯mers of the짯se motherboards.

We will deve짯lop and enable our mother짯board part짯ners with the code to sup짯port 쏾en 3-based pro짯ces짯sors in sel짯ect beta BIO짯Ses for AMD B450 and X470 motherboards.
The짯se optio짯nal BIOS updates will disable sup짯port for many exis짯ting AMD Ryzen꽓 Desk짯top Pro짯ces짯sor models to make the neces짯sa짯ry ROM space available.

The sel짯ect beta BIO짯Ses will enable a one-way upgrade path for AMD Ryzen Pro짯ces짯sors with 쏾en 3, coming later this year. Flas짯hing back to an older BIOS ver짯si짯on will not be supported.

To redu짯ce the poten짯ti짯al for con짯fu짯si짯on, our intent is to offer BIOS down짯load only to veri짯fied cus짯to짯mers of 400 Series mother짯boards who have purcha짯sed a new desk짯top pro짯ces짯sor with 쏾en 3 insi짯de. This will help us ensu짯re that cus짯to짯mers have a boota짯ble pro짯ces짯sor on-hand after the BIOS flash, mini짯mi짯zing the risk a user could get caught in a no-boot situation.
Timing and avai짯la짯bi짯li짯ty of the BIOS updates will vary and may not imme짯dia짯te짯ly coin짯ci짯de with the avai짯la짯bi짯li짯ty of the first 쏾en 3-based processors.

This is the final pathway AMD can enable for 400 Series mother짯boards to add new CPU sup짯port. CPU releases bey짯ond 쏾en 3 will requi짯re a newer motherboard.
AMD con짯ti짯nues to recom짯mend that cus짯to짯mers choo짯se an AMD 500 Series mother짯board for the best per짯for짯mance and fea짯tures with our new CPUs.

The짯re are still many details to iron out, but we셶e alre짯a짯dy star짯ted the neces짯sa짯ry plan짯ning. As we get clo짯ser to the launch of this upgrade path, you should expect ano짯ther blog just like this to pro짯vi짯de the remai짯ning details and a walk짯th짯rough of the spe짯ci짯fic process.

At CES 2017, AMD made a com짯mit짯ment: we would sup짯port AMD Socket AM4 until 2020. We셶e spent the next three years working very hard to ful짯fill that pro짯mi짯se across four archi짯tec짯tures, plus pio짯nee짯ring use of new tech짯no짯lo짯gies like chip짯lets and PCIe짰 Gen 4. Thanks to your feed짯back, we are now set to bring 쏾en 3 to the AMD 400 Series chip짯sets. We셱e gra짯teful for your pas짯si짯on and sup짯port of AMD셲 pro짯ducts and technologies.

Nur von X370, B350 und A320 ist mit kei짯nem Wort die Rede.
