> Support for new and evolving technologies like PCIe® Gen 5 and DDR5 memory empowers users to grow with their Socket AM5 solution, which AMD will support with platform longevity through 2025 Does it seem like sockets are getting less and less years of support? Just 3 years of "longevity" doesn't seem that long, I probably upgrade my CPU once per 3 years and that would mean if I now move to AM5, I'm gonna have to yet again get a new motherboard when AM6 gets launched in ~2026.

Intel have been doing two generations of support for absolutely ages. AMD doing four generations on AM4 was the outlier rather than the norm, and it sounds like they are giving themselves wiggle room this time to do similarly, but potentially cut it a bit shorter if they feel they need to. Given how many reviews talked about AM4 chips being a no-brainer upgrade choice if you had an existing board, they have incentive to do it. AM4 being on DDR4 and older motherboards being PCIe 3 really limited it. Given DDR5 is new and PCIe 5 is brand new, it feels like AM5 has plenty of potential to go longer, but I can understand not wanting to tie themselves too far ahead. I think it's more a matter of target: Intel probably care most about the pre-built market where people just buy a new computer, so there isn't much value. AMD focused on taking the enthusiast crowd and getting the mindshare that way, and long socket support definitely benefited them there.

  AM4 being supported for that long caused more trouble than it was worth IMO. When buying a new CPU+motherboard, you had to make sure you got a motherboard with a new BIOS, since BIOS updates were required to support new CPUs. AMD would even send out older CPU models just to help consumers update their BIOS of necessary. A lot of cheaper motherboards didn't have enough flash memory to support both the last and the first CPUs, so you had to make sure not to install the wrong BIOS update or your CPU wouldn't work anymore. Intel's approach, which means you can always count on the BIOS supporting your CPU if the CPU physically fits, and which meant a BIOS update would never remove support for your CPU, is honestly arguably the more consumer friendly approach.
  - Latty 4y ago
    Eh, it's a trade-off for sure, but "consumer friendly" is a stretch. Intel still have the issue of requiring BIOS updates for new CPUs, and the issue with having to remove BIOS support can be solved by just telling motherboard manufacturers to spec larger for it so they have room for more. In contrast, the upside of being able to slot a Ryzen 5000 CPU into a machine that you bought for first gen is a big deal in terms of the lifetime of those other components, and gives consumers a lot of flexibility. I get some people just won't utilise that and will buy fresh, but just because it isn't worth it for you personally doesn't mean it isn't a good feature more generally.

      > and the issue with having to remove BIOS support can be solved by just telling motherboard manufacturers to spec larger for it so they have room for more. I think I've read somewhere that the cause of that issue was that the SPI block on older AM4 CPUs can only address up to 16 megabytes of the SPI ROM chip. There's not much the motherboard manufacturers can do, when it's hardware on the CPU itself which does the reading directly from the ROM chip.

    I'm not sure requiring a new motherboard vs flashing a bios is consumer friendly, unless you assume the consumer is loaded and technically illiterate. If someone paid me $150 to flash a MB, I'd probably take that deal every time.
    - mort96 4y ago
      Sure, but if I'm buying a new CPU+motherboard combo anyways, I'd prefer if that just worked and I didn't have to acquire a temporary old CPU for the purposes of flashing BIOS with the CPU I actually want to use.

  >Intel have been doing two generations of support for absolutely ages. It's worth noting that most of that was artificial; just enough electrical incompatibility to make you buy a new motherboard if you wanted a new processor (it's ultimately all just slightly different configurations of LGA1156 anyway- look up ASRock's P67 Transformer for more conclusive proof). Back when they were competing against AMD (pre-2007) they only had one socket, that being LGA775 running from Prescott Pentium 4s all the way through the last Core 2 systems, and supported it for a very, very long time. Sure, it'd require your mainboard manufacturer to keep up to date with BIOS updates to support the new CPUs, but they were ultimately all compatible.

They are committing to minimum 2025. This gives them the flexibility to either continue support or make changes if new CPUs require new sockets. Regardless it’s still better than intels 2 generation change. With AM5 you should get 4-5 generations of cou minimum.

  AMDs roadmap says Zen 5 in 2024, so you’ll be more likely to get 2 or possibly 3 generations.
  - philliphaydon 4y ago
    Hmm I thought the roadmap for zen 5 was 2023? But also we will get Zen4 3d, there will prob be Zen5 3d, and if Zen6 is AM5, that makes 4-5 generations.
    - Tuna-Fish 4y ago
      In the event yesterday they "confirmed that Zen 5 was on track for 2024".
    - Godel_unicode 4y ago
      This is probably exactly what their marketing people will try to say, yes. “No no, we added some cache, new generation!” I’m waiting for them to call each chip it’s own generation, and then we can add another generation for the APUs, and now we’re probably well into the double digits.

  And deservedly so, since it’s just marketing fluff. Like how having 7 foo in your bar suddenly became “over 7 foo”. Take the difficult upgrade history with zen 3 and older boards, add the roadmap with Zen 5 in 2024, and what this estimate says is they’re planning on AM5 for Zen 4 and 5.

Not really, Intel has been rolling out a new socket every 2 years (give or take) for pretty much all of the 2000s. AM4 was very much a departure from the norm, and it’s also the case that compatibility was a pain in the ass. Whenever you wanted to upgrade you needed to read data sheets, watch reviews, wait for AMD to change their mind^, and then flash the AGESA on your board and hope. ^ https://arstechnica.com/gadgets/2022/03/amd-reverses-course-will-support-ryzen-5000-in-old-b350-and-x370-motherboards/ https://arstechnica.com/gadgets/2022/03/amd-reverses-course-...

I know AMD had a lot of trouble with the interposer after Zen2 or so, due to being stuck on the same socket. Keeping compatibility became more and more expensive. Though Zen 1 was a much different product than the later generations (no I/O die) so maybe that was an unusually bad situation.
