Phasmid: Intel's problem was that they had everything on their 14nm process for ages, so much so that they had to start using 22nm for chipsets again to drop the congestion down a bit. Now that 10nm (or 'Intel7' per rebranding) is working a bit better they've
theoretically got a decent amount of excess capacity- but it isn't really translating to practical excess since the process is only more reliable, not reliable in an absolute sense.
Yep, they struggled for years with their 10nm node and still have a ways to go with it and newer nodes.
Phasmid: The first 10nm chips were all limited to 4 cores and laptop applications since the process was so broken, they've got the reliability up a lot more so they can economically do higher core count CPUs. But the reliability is still too poor for them to do GPUs with their 10nm, so all their new GPUs will be made by TSMC and competing with AMD for space there. Unfortunately it's unlikely they will add much in the way of new competition because they'll just be competing for the same production with AMD.
Well, yes and no... AMD has bought wafers at TSMC years in advance, so they've already secured everything they need on TSMCs various nodes at least for what they originally intended to produce. They're also buying up as much more space on TSMC's various nodes as they can based on the unexpectedly huge demand and massive profit they've made over the last year or so as it becomes available. Both Intel and Nvidia have secured some wafers on TSMC 5nm and I think Intel has some 4nm or 3nm there also, but AMD's already one of TSMC's biggest customers and secured what they need for quite some time now. So there is some competition in the sense that I'm sure AMD would like to have got allocation of what Intel or Nvidia got, but it is quite small compared to what AMD has booked. AMD is allegedly booking at Samsung also for some future products as well.
VIrtually all semi fab companies are building new fabs in a number of countries all slated to start coming online in 2023 or thereabouts so we should see production capacity virtually everywhere increase in 2023. We'll probably see the shortages continue on some products throughout 2022, but in 2023 we should see supply start to keep up with demand everywhere if it hasn't already by then. I don't think AMD's going to have any problems nailing down access to silicon personally as they've booked it long in advance.
The second problem from what I understand, is that because many of these much much older boards are so many years old, they existed long before these new CPUs existed in silicon so they could never be actually tested on these boards, and there could be a variety of timing problems, or other issues.
Phasmid: The issue with that (and the BIOS size) is that support
has been added for some budget board lines, ie 320 series boards despite those problems. Those boards are really pretty cheap and nasty with poor components, have outright bad VRMs etc. If they can cope with a 5000 series CPU then a 350/370 definitely should be able to as well. It would still be a big improvement even if they locked overclocking.
Sure, but it still has to be adequately tested and work or it is a disservice to the customer. There also has to be enough business incentive for the companies to expend the effort also and they might feel there is on some products and not on others. I doubt we'll see universal support added retroactively to every motherboard as it wont make good business sense on every single product out there. Hopefully it does happen everywhere it does make sense though.
Lets face it though too, the AM5 platform has survived an extremely long time now and AMD has delivered way more than anyone ever expected including themselves. They shouldn't be attacked by people with angst if some of the processors don't get supported on some boards, they should be praised for allowing it to even live this long at all IMHO which is a testament to their commitment to their consumers. I don't think they can be expected to stretch it out forever though or be seen as being bad otherwise, it's not realistic to me to expect that level of support for this long but it is a nice thing when they go out of their way to do it where most other companies would never even consider it.
I speculate that AM5 will support processors for 3 generations before moving on to AM6 or whatever though, I don't think we'll see it last as long as AM4 did, as there are way too many changes occurring in semiconductor manufacturing right now that probably can't all be anticipated this far in advance to keep a socket+platform optimized for products much longer than that.
Either way, I think it's a great time for tech and competition, minus the GPU shortages and scalping and elevated pricing in general.
