AMD's full press release is given below.As we head into our upcoming “Zen 3” architecture, there are considerable technical challenges that face a CPU socket as long-lived as AMD Socket AM4. For example, we recently announcedthat we would not support “Zen 3” on AMD 400 Series motherboards due to serious constraints in SPI ROM capacities in most of the AMD 400 Series motherboards. This is not the first time a technical hurdle has come up with Socket AM4 given the longevity of this socket, but it is the first time our enthusiasts have faced such a hurdle.Over the past week, we closely reviewed your feedback on that news: we watched every video, read every comment and saw every Tweet. We hear that many of you hoped a longer upgrade path. We hear your hope that AMD B450 and X470 chipsets would carry you into the “Zen 3” era.Our experience has been that large-scale BIOS upgrades can be difficult and confusing especially as processors come on and off the support lists. As the community of Socket AM4 customers has grown over the past three years, our intention was to take a path forward that provides the safest upgrade experience for the largest number of users. However, we hear you loud and clear when you tell us you would like to see B450 or X470 boards extended to the next generation “Zen 3” products.As the team weighed your feedback against the technical challenges we face, we decided to change course. As a result, we will enable an upgrade path for B450 and X470 customers that adds support for next-gen AMD Ryzen™ Processors with the “Zen 3” architecture. This decision is very fresh, but here is a first look at how the upgrade path is expected to work for customers of these motherboards.
[*]We will develop and enable our motherboard partners with the code to support “Zen 3”-based processors in select beta BIOSes for AMD B450 and X470 motherboards.
[*]These optional BIOS updates will disable support for many existing AMD Ryzen™ Desktop Processor models to make the necessary ROM space available.
[*]The select beta BIOSes will enable a one-way upgrade path for AMD Ryzen Processors with “Zen 3,” coming later this year. Flashing back to an older BIOS version will not be supported.
[*]To reduce the potential for confusion, our intent is to offer BIOS download only to verified customers of 400 Series motherboards who have purchased a new desktop processor with “Zen 3” inside. This will help us ensure that customers have a bootable processor on-hand after the BIOS flash, minimizing the risk a user could get caught in a no-boot situation.
[*]Timing and availability of the BIOS updates will vary and may not immediately coincide with the availability of the first “Zen 3”-based processors.
[*]This is the final pathway AMD can enable for 400 Series motherboards to add new CPU support. CPU releases beyond “Zen 3” will require a newer motherboard.
[*]AMD continues to recommend that customers choose an AMD 500 Series motherboard for the best performance and features with our new CPUs.
There are still many details to iron out, but we’ve already started the necessary planning. As we get closer to the launch of this upgrade path, you should expect another blog just like this to provide the remaining details and a walkthrough of the specific process.At CES 2017, AMD made a commitment: we would support AMD Socket AM4 until 2020. We’ve spent the next three years working very hard to fulfill that promise across four architectures, plus pioneering use of new technologies like chiplets and PCIe® Gen 4. Thanks to your feedback, we are now set to bring “Zen 3” to the AMD 400 Series chipsets. We’re grateful for your passion and support of AMD’s products and technologies.ps：搞不好am4还要再拖多一代（绿字）

可以理解
b450 4相供电都能带满血3950x了
要是支持4000系谁还买x570了 要是zen3还用b450，人类还要不要进步了 椎名祐 发表于 2020-5-7 22:11

期待这个不如期待板厂小动作
a320也是支持3950x的嘛 表格里说A320并不支持zen2，然而现实中是支持的，所以这张表嘛 官方还说A320不能超频呢 qazesz 发表于 2020-5-7 22:24
官方还说A320不能超频呢
还真不能
那个能超的用的是b350 但是命名成a320 桌面4000系列比移动4000系列强多少？ 所以战未来还得上b550吗？ 兼不兼容感觉就是一个bios的事情，针脚又没换 苏小幼 发表于 2020-5-7 22:37

也不用战未来了，zen3是最后一代AM4。唯一不清楚的是zen3的apu是AM4还是AM5
—— 来自 Xiaomi Redmi K20 Pro, Android 10上的 S1Next-鹅版 v2.2.2.1 还在用1700和b350的老用户就等着一波看年底11代intel和zen3哪一位更加好了
最后一代DDR4再顶个至少3年吧 能选两个nvme x2配置还是有点用的，就看4.0的消费产品能不能尽快跟上了

说得很好，应该让你来当设计师 两个nvme…香 b350刚换3600
amd已经很良心了

年底11代直面发布我觉得都危险 跟10代间隔半年太草了
之前也有一代这样的。
去年12月tigerlake-u的es1出来，今年中旬发布，上月月末rocketlake的es1出来了 强尼高达 发表于 2020-5-8 08:48

牙膏厂都有魔改bios让Z170支持八九代酷睿，AMD总不能比牙膏还坑吧
就好比上面说的A320在表格里不支持ZEN2一样，但实际上能支持 404489039 发表于 2020-5-8 09:14

有两种
一种是技嘉的A320,读作A320写作B350
一种是华擎的A320,读作A320写作魔改

顶多就是首发咔你一下,过几天就纷纷表示我们的攻城狮突然脑袋开窍写了支持ZEN3的新BIOS了~~~起码四系应该是没问题的,三系真有点危险,如果BIOS主体没大变的话,到时候还可以期待民间高手直接提取X570的SMU替换 那些16m的bios要支持ryzen4000估计界面得改命令行了 planned feature support, subject to change按图里X570也是不支持1代，实际情况基本都支持的，看板厂了 gaiden 发表于 2020-5-8 10:29

往前支持没难度，P45理论上也不应该支持65nm Core 2 Duo的实际上连奔4都支持了，但是你要让P965支持45nm就得看大家技术和良心了，至于奔4主板想支持Core 2 Duo更是门都没有因为VRM改了 creymorgan 发表于 2020-5-8 10:22

AMD自己的说法,X470/B450是能支持的,而X470和B450和很多X370/B350甚至可以BIOS互刷直接用,so,这根本就不是个技术问题,而是一个态度问题 技嘉的X570经常有活动，千元以内就能搞定，映泰的X570常年999，臭打游戏买个丐板570足矣 KOGmk2 发表于 2020-5-8 11:02

你自己再好好看图，B450就不支持Zen 3了好吗
很多时候的确是态度问题啊，几年前的主板谁还在卖，花那么多人力帮你做兼容得不到一分钱好处，做不做全凭良心
但有态度没技术也不行啊，还记得天国的965P-DS3 1.0么
所以是AM4平台X570就到顶了？ 攻守俱其土肉狐 发表于 2020-5-8 12:08

反正就是再等等，等等永远不亏 z170魔改能不能上10系啊，都是一个祖传架构 lbzlxx 发表于 2020-5-8 12:38

接口都不一样了，要魔改只能换插槽，总不能指望像图吧那样捣鼓775转771转接器吧
