You're confusing bandwidth and latency. Ryzen 3000 launched a month ago, the 3900x outperformed expectations, so the initial shipments sold out faster than expected. You can't magic up stock out of thin air, so there's an inevitable lag between retailers reporting unusually high demand and AMD being able to deliver sufficient stock.
The bandwidth question is much more important and bodes very poorly for Intel. TSMC's 7nm process is stable, providing excellent yields and has plenty of available capacity; they're already in risk production for 5nm, which is expected to free up substantial capacity at 7nm/7nm+ into 2020. Intel's 10nm has been a complete debacle and (despite the Ice Lake launch) is still blighted with sub-par yields.
Yields in terms of getting lots of operational dies, sure, but one of the underlying problems here is chip quality. They have lots of chiplets but most of those chiplets are not fast enough to hit the clocks advertised for the 3900X.
In fact, even a lot of the chiplets sold as 3900X are not fast enough to hit the clocks advertised for 3900X, as well as elsewhere throughout their range. There are a lot of people finding their chips only boost to 50-200 MHz less than the advertised frequency of the chip.
Essentially, the boost algorithm now takes chip quality into account when determining how high it will boost. And most of the chips have silicon quality that is too poor to hit the advertised clocks, even on a single core, even under ideal cooling, etc etc.
Thus, AMD has the somewhat dubious honor of being the first company to make the silicon lottery apply not just to overclocking, but to their stock clocks as well. They really wasted no time before shifting to anti-consumer bullshit of their own; all they had to do was advertise the chips as being 200 MHz lower and everyone would have been happy, but they wanted to advertise clocks the chips couldn't hit.
And again, the underlying problem is chip quality - a lot of these chiplets can't boost to 4.3 or 4.4 GHz let alone 4.7. AMD simply can't yield enough 4.7 GHz chiplets to go around, even if the chiplets are nominally functional. The process may be "stable and providing excellent yields" but it's not stable and well yielding enough to meet AMD's expectations.
That's a major reason they're now introducing 3700 and 3900 non-X variations - that will allow them to reduce clocks and satisfy demand a bit better.
New architecture, new chipset, bound to have some release issues. Intel is on its second or third refresh of their Skylake architecture from 2015, all ironed out.
More like the fourth, I think.
So to be clear, older AGESA isn't a magic bullet that is letting all chips "easily hit their rated boost clocks".
It could be cleaned up somewhat in future AGESA releases, and silicon quality will definitely go up over time.
Do you have some sort of source for this claim?

A lot of reviewers have noted similar things, but often are working with singular samples and didn't want to make too much of a stink without more data, but the problem is widespread. Out of all of der8auer's CPUs, only one hit its advertised boost clocks, and it was one of the lower-end CPUs with a less ambitious target to hit.
It may be a problem with early AGESA firmware, and silicon quality will definitely go up over time, but at least at this point in time AMD has certainly falsely advertised the clocks these CPUs are capable of achieving.
As it stands, this mine has some dead canaries.

That's hearsay not actual justification. And intel has a reputation for dirty play.
It is unclear whether Intel is truly disadvantaged in throughput for any appreciable length of time. We've seen what happened to Intel after the disastrous Prescott release years ago - they worked on the Core architecture and its follow-up Core 2 that put AMD in a pretty serious rut for the past decade. Your point of the 10nm offering launching and _still_ being lackluster is the big, big problem for Intel for short-term competitiveness.
I'm experiencing the opposite. There has been so many deals on 3900X that I have to constantly tell myself I don't need an upgrade.
This doesn't necessarily completely invalidate my point though - distribution by AMD is clearly needing some work when one region is drowning in 3900X processors and a very wealthy metro area has none in retail channels.
This strategy is quite widely used in many other industry as well.
Although given it has only been launched for less than a month and demand is actually through the roof ( I have been seen reviews being so Pro AMD, even in the AMD Athon 64 days ). So I think it is simply supply is a little tight while TSMC are working hard.

I hope this letter finds you in good health. Since I've seen that you are offering AMD 3900X at a discount, I'd like to inform you that I am not like those pleebs and would therefore like you to pay in full MSRP. Please let me know where I can send the goats.
I have the honor to be your obedient customer.

B&H Photo is a reputable site, and they are advertising the 3900X at $499. Now whether they will ship anytime soon...
In fact Intel had supply issues with their 9900K at launch too, for at least a month or two they were often out of stock at the major retailers. If getting ahold of a 3900X is still tough by next month then maybe that's cause for concern.
I would agree that Intel is more mature on the BIOS side of things. AMD usually has launch issues that need to be ironed out with UEFI updates. But, if the past few launches are any indication, they've always got things fixed.
Next month, the 3950X will be the one hard to get a hold of.
These chips launched on schedule on 7/7, almost exactly one month ago. If you've been exasperatedly waiting for months it's not AMD's fault.
The "literally no reason" part is okay, what you need to do is adjust "at the moment" to "once we're out of the launch window".
i have one and there is no bios issue. i got the cheapest x570 mobo and everything is great
I've been holding out on building a desktop because I could go for a while without it but my patience is wearing very thin after waiting months and now having to wait even longer just to get CPUs in stock in the first place.
Intel's advantage is OEMs and sheer output volume, but the hyperscale infrastructure folks are going to be shoring up AMD financially while Intel has problems and maybe in two years or so of this nonsense AMD might be much more of a serious decision, but as of this moment it isn't a slam dunk for AMD at all.
