Update at the top: Here's our article on today's launch!
11:52AM EDT - One of the most anticipated launches of 2020 is now here. AMD's CEO, Dr. Lisa Su, is set to announce and reveal the new Ryzen 5000 series processors using AMD's new Zen 3 microarchitecture. Aside from confirming the product is coming this year, there are very few concrete facts to go on: we are expecting more performance as well as a competitive product.

I'll just go and bu... oh, wait. I can't.zanon - Thursday, October 8, 2020 - link
They've got a new socket coming, and chips will be starting to move over to requiring it in the next few releases (Epyc 4 'Genoa' for example will be the first of those to go to SP5). But a long run time on socket has its advantages, particularly for AMD. First and most obviously, it allows end users to potentially amortize their investments a bit more and upgrade to new chips more easily. But second, AMD hasn't been Intel, they've lacked the sway to just take for granted that mobo makes themselves would always rapidly adapt to anything they did. A stable platform has no doubt been helpful in ensuring a variety of decently solid options for buyers.baka_toroi - Thursday, October 8, 2020 - link
I don't think they make that many sacrifices. It's not like AM4 CPU compatibility spans every single motherboard and chipset. You still have to replace your 1st gen AM4 motherboard if you want to use Zen 3.AMD's socket policy seems quite sane and healthy. It's not like they'll continue using AM4 when Zen 4 is released.
Mr Perfect - Thursday, October 8, 2020 - link
The premise of five years of AM4 was great, but it did not turn out not sane and healthy. You can literally buy an AM4 CPU, plug it into an AM4 motherboard and have it not work! The compatibility matrix is a mess.I suspect a lot of that is down to the small BIOS chips that can't store five years worth of CPU microcode, but it's still a compatibly nightmare. Hopefully they require larger BIOS chips for AM5 and consumers will be able to use any AM5 CPU in any AM5 motherboard, because that's the real reason to keep a socket around for five years.

Compatibility is entirely dependent on the manufacturers and their insistence of using X sized bios files.Not to mention how flashy their motherboard bioses are.
They could cutdown graphics on their bios to allow more cpus.

Where have you been?Everyone knows this is the last processor on this socket. Were you expecting a new socket now just for zen3 then a new socket for Zen 4 and DDR 5?
nathanddrews - Thursday, October 8, 2020 - link
I have to believe that AMD's decision to work within the bounds of the AM4 socket was in part a budgetary constraint. It *has to* be cheaper to design your new CPUs around a socket than to build a new socket with every CPU.Hul8 - Thursday, October 8, 2020 - link
I think it also has the effect that AMD and the board partners can concentrate on premium motherboards on launch of a new line of CPUs (like it was with desktop Ryzen 3000/X570 launch); The budget options from the previous generation (B450) as well as more affordable predecessors (X470) are compatible with the processors so there is no rush for a complete lineup change.Not only does it allow board partners to upsell premium motherboards to customers who don't really need the features but want the "latest thing" (gaining AMD favor with the partners, and incentivizing lots of designs and competition), it also gives more time to iron out teething BIOS issues, only having to deal with a single chipset at a time.
kolasin2 - Thursday, October 8, 2020 - link
In addition, I think it gives mobo manufacturers the ability to decouple their motherboard offerings from CPU releases. With Intel, you know you'll have a new Zx90 every other generation of CPU, since the socket changes. With AMD, board partners can focus on releasing their products knowing the socket won't change, so they do not need to be lockstep with AMD's release schedule. All they need to worry about is a BIOS update.dotjaz - Thursday, October 8, 2020 - link
Exactly what exactly did you sacrifice?
