AMD is Allegedly Preparing Navi 31 GPU with Dual 80 CU Chiplet Design
AMD is about to enter the world of chiplets with its upcoming GPUs, just like it has been doing so with the Zen generation of processors. Having launched a Radeon RX 6000 series lineup based on Navi 21 and Navi 22, the company is seemingly not stopping there. To remain competitive, it needs to be in the constant process of innovation and development, which is reportedly true once again. According to the current rumors, AMD is working on an RDNA 3 GPU design based on chiplets. The chiplet design is supposed to feature two 80 Compute Unit (CU) dies, just like the ones found inside the Radeon RX 6900 XT graphics card.
Having two 80 CU dies would bring the total core number to exactly 10240 cores (two times 5120 cores on Navi 21 die). Combined with the RDNA 3 architecture, which brings better perf-per-watt compared to the last generation uArch, Navi 31 GPU is going to be a compute monster. It isn't exactly clear whatever we are supposed to get this graphics card, however, it may be coming at the end of this year or the beginning of the following year 2022.

This could also bring down prices as they could do as they do with zen now and have the IO on a cheaper larger process node and just have the compute parts on 7 or 5nm etc.
And it turns blind eye to already voiced "but you can't just ramp up production at will".
And no, "but you can produce it in advance" does not fly, production starts only a few months before sales, as chips that go inside consoles are rather new.
At the same time, these chips are produced for the cutting edge of consumer hardware, so you can't just relegate that to older nodes and be done with it - that directly hurts the selling point of your new product, if it doesn't kill it altogether.
I'm still puzzled by the whole entitled attitude wrt buying luxury products like these. Still whining about scalper prices. This is how free markets work, if it took you until today to figure that out... well... welcome to Earth. It's been like this for over 2000 years, ever since we discovered the concept of trade. Scarce = expensive. Simple.
I don't quite remember where, but I raised the exact question of why nobody seems to have seen this coming despite a situation like this needing several years to take place in some other thread. It's frankly rather baffling, and makes me wonder if it's simply down to consolidation (ever fewer actors competing in every part of the value chain) or if the problem is more fundamental than that. I mean, we all know how the memory industry actively works to maintain just the right amount of scarcity to keep prices high without triggering a crisis, so I'm suspecting similar ideologies to be at play here as well in some form or other. I.e. nobody wants to compete in the high-end fab business just to break even (or perhaps more precisely, investors wouldn't allow them to, would tank their stock prices and drive them into bankruptcy for not being profitable enough), but someone somewhere must have seen where this was going.
A decreasing rate of node improvements has no doubt contributed by squeezing ever more products onto an ever smaller collection of nodes, as has ever-increasing chip demands for an ever expanding range of products (light bulbs 10 years ago didn't have much silicon in them, nor did toasters or coffee makers), but the assumption from that if going by simple supply/demand logic would be a continuous expansion of the silicon fab industry. Of course building a fab is a 5+-year, multi-billion-dollar bet, so there can't be many companies willing and able to make those bets, but it still seems really weird that so few seem to have seen this as a major opportunity. I guess the increased digitalization of ... well, everything is likely the biggest contributor here (the amount of advanced computation taking place in contemporary cars is downright staggering), but it also seems to me that the loss of GloFo in the high-end fab space was a bigger blow than anyone seemed to notice, and it's starting to look like Intel's previous 14nm shortage was more of a precursor to a broader problem than anyone thought. I mean, since 2017 we've gone from 3 major high-end fab actors to 1, with Samsung being the perennial outsider looking in but somehow seeming to be number two now? It's all rather weird.
It's maybe even more baffling again that there are currently major, long-term shortages for ... silicon wafers and chip packaging substrates. I mean, really? I get that wafers require very pure silicon and highly specialized equipment, but it's still just monocrystalline melted sand spun into a cylinder(-ish) and cut into discs, and packaging substrates are ultrafine fiberglass and copper sandwiches. Are these things that difficult to scale up? Or are the forces behind these industries just not interested in investing into expansion due to the commodity nature of the products?
So while I am in some sense frustrated that there's a sudden and systemic shortage of what seemed to be widely available consumer products pretty much yesterday, I'm more baffled by just how unprepared the industry seems to be for the direction it's growing in, especially given just how the very same industry constantly promotes how computerization of anything and everything will somehow save the world. It just looks like they "suddenly" got their wish (well, over 10+ years), yet had never really imagined it actually happening, and certainly hadn't actually considered what that scenario coming true would actually mean.
We live in a paper reality and the pandemic shows us where the problems really are. The same thing occurs in politics especially in first world countries. Netherlands, the UK, the US.. we are fuckihg failures with no direction whatsoever. No perspective and no vision. The stuff that happens over here lately you coukdnt think it up. And its all down to that same distanf mentality: managers trying to manage nothing but their own PR.
Thats that top 3% for ya.
There has not been A SINGLE MAJOR CONSOLE LAUNCH when product was not sold out for many weeks.
Because there is BURST demand in the beginning that nobody can match production capacity wise.
Because you cannot have BURST production and neither could you afford producing stuff YEARS before launch.
"Oh, you suddenly need 10 times normal supply of X? Well, am I supposed to build additional production capacity just to satisfy your needs for the next 3 onths???"
How hard is that to comprehend?
In such situation, something being sold out is NOT and can NOT be a sufficient indicator of someone mis-calculating sales.
There is exactly ZERO evidence either Sony or Microsoft underestimated demand for PS5 and XSex respectively. Someone sane expected demand for AT HOME ACTIVITY goods to DROP due to covid?
/facepalm
PS
And on purchasing and supply chains, including logistics.
I have, in fact, been working with IT projects in the are.
Stop trash talking about those guys, the do their job pretty damn well, in facts, it's shocking how good they are at something that complex.
Secondly, the burst of initial demand is exactly why stocks are built up beforehand. You're not saying anything that hasn't already been addressed at length. If absolute peak production is X consoles/month, expected normal demand is, say, 1/2 X (to ensure sufficient production overhead to account for sales fluctuations), and launch month demand is expected to be 5X, then you try to produce consoles at maximum capacity for 5 months before launch to ensure sufficient supply. That's common practice, I'm just saying they missed their estimates. Of course there are tons of complicating factors like the added difficulty of shipping and distributing huge quantities just before launch (compared to the steady flow of regular sales), but given the sustained lack of stock, that clearly wasn't the issue. It is of course entirely possible that demand has been so high that no possible amount of pre-launch production could reasonably have ensured availability, but if that's the case, the companies involved should (and likely would) have addressed it far more clearly than they have.
Third, of course there is evidence of underestimated demand. There being no stock is evidence of that. Nobody plans to be sold out for months and months - consoles are a low-margin business reliant on after-sales, so every sale that doesn't happen hurts their bottom line. You can't buy games for a console you don't have, so they clearly plan to have the product available at all times. Nobody plans for stock shortages unless they're in the fashion industry. Again, there is a possible second explanation: component shortages beyond the control of the console maker. But again, if that was the case, why haven't they addressed that publicly? It's no skin off their backs to say "sorry, we're working as fast as we can, but we're struggling to get a hold of [component A] and production volumes are thus lower than our targets."
Fourth: please reread. I very clearly didn't say anyone expected at-home activity to drop due to covid, I said that the influence of covid on demand might be one of the reasons why their estimates were off, as it's an unknown factor that obviously makes estimating demand much, much more difficult. (Especially as it works both ways: on the one hand there's increased demand for at-home activities, while on the other hand a lot of people are struggling financially. Balancing the two without any real data to go by - which doesn't exist - is essentially just guesswork.) I mean, at this point you're just misreading me on purpose if that's what you got out of that sentence. Please take a breath and swallow your indignation, as it's causing you to not actually read what I'm saying.
Fifth: "trash talking"? Seriously? I mean, get a grip, man. This is just ridiculous. Saying that a vaguely defined group of people spanning dozens of companies and hundreds if not thousands of people missed some estimates and thus seriously messed up a product launch constitutes trash talkingto you? Calm down, please. There's nothing personal in this, neither directed at you or at anyone involved in this process. Not even anything saying they're bad at their jobs - I've never said anything to that effect. Estimates are always estimates, they are never a sure thing. This just happens to be a much bigger mess-up than what we normally see. Stop making this personal.
Chiplets on GPU! Curious about the result of such implementation and if RYZEN is anything to go by, I'd say Nvidia Lovelace just got a good run for their money. Sony themselves said the real PS5 games won't be available before 2022.

Supply - If you look at the timeline, COVID lockdowns hit really hard when the products are supposed to start or started mass production. So if AMD for example have an obligation to fulfill XXX number of XBOX and PS5 SOCs, it is likely they will fall behind in the production. So when things started to improve towards the end of the year, they are still busy trying to fulfill those orders. As a result, there is a knock on impact to producing Ryzen 5000 and RX 6900/6800. And don't forget, the lockdowns did not happened concurrently globally, they took place at different times, and with different durations. So I am sure there will be parts/ components shortages.
Demand - Having launched multiple times in the past, both AMD and Nvidia are very seasoned when estimating demand. But I feel the exception this year is that AMD became very competitive against Nvidia's Ampere. In the past few generations, it has always been a cake walk for Nvidia and they can afford to price their products at a premium. As a result, Nvidia generously handed gamers a GA102 chip @ USD 699, and the GA104 @ US 499. I feel Nvidia would have priced the RTX 3080 easily at USD 999 without competition, or give you a RTX 3080 based on the smaller GA104 chip. So it came as a surprise to us all, and sells like hot cakes. Of course the GA102 being a big and complex chip, was never meant to be mass produced in large numbers to begin with. As AMD joined the party late, they know they can't compete in terms of features, so accordingly have to price their RDNA2 flagships lower to compete. So its not that AMD or Nvidia did not expect demand to be high, its because competition forced them to compete on price vs performance, hence causing the imbalance between supply and demand. At least this is my opinion.
Once again, for particularly bright people: there are reasons OTHER THAN underestimating demand that lead to product shortages. Such as, you know, MANUFACTURING. AMD would love to bump production of its stuff by about 50% more waffers, except, nopie, TSMC is at full capacity, you know.
BUT CAN'T I BUILD IT IN ADVANCE? Yes, you can, what we got now was built in advance, as early as it was technically possible.
And again: total sales numbers don't matter much if there's a sustained shortage - the shortage itself tells us that there is insufficient supply, which is a supply-side issue. You're presenting it as if this is only down to higher than normal demand, which is simply not true. Demand is indeed higher than normal, but supply is also significantly constrained, and its reasonable to say that console makers should have been aware of these challenges and done their best to account for them. It's also entirely possible that they have done so, but given the distinct lack of clear public statements about this that doesn't seem like the most reasonable assumption. I think you're being far too generous with Nvidia here. Remember, Turing prices were unprecedented bad value over previous generations. $699 for the 3080 isn't generous as much as it is a return to a semblance of normalcy, though the lack of $300 and below products still tells of skewed market with a harmful focus on high ASPs and profits. Hopefully the Ampere and RDNA2 stacks will fill out soon to rectify this, but until then we still have a really bad GPU market regardless of supply. Of course production costs are rising (10GB of GDDR6X costs more now than 4GB of GDDR5 did for the 980, after all, and a huge die on 8nm costs a lot more than a huge die on 28nm), but that still doesn't explain the huge cost increases we've seen in recent years.
But other than that, yeah, it's clear that there's an unprecedented confluence of supply-side issues and higher than normal demand. It also seems like the supply-side issues run down the production chain quite a bit, which is quite worrying. A demand spike is one thing, but it shouldn't be enough to trigger what we've seen over the past few months.
You were specifically told about "no, you can't go into preproduction as early as you will at least twice in this thread. Ironic. There is exactly ZERO indication of console APUs not being produced half a year before launch, nor is there any evidence of that possibly having any visible effect on availability TODAY. In other words, instead of admitting the obvious (made up accusations of "miscalculation of demand") let's call that weird theory "most reasonable assumption", shall we...
As for reasonable assumptions: do you have any arguments to say that it's unreasonable to think this could have been handled better? Because I have yet to see any, beyond you somehow claiming that I'm insulting the people doing these jobs, which ... isn't an argument, but a derailing tactic.
And again: if we had seen statements from console makers to the effect of "we're producing these as fast as we can, but volumes are constrained by factors outside of our control" or something similar (which is quite common) we could have reasonably believed that they had been on this from early on and had been actively working to improve supply. Instead, all public evidence points towards initial sales estimates being significantly below actual demand, with console makers then having to scramble to increase volumes after launch. Which, as we have both been saying, takes quite some time, and likely won't have noticeable effects for several months, if not half a year.
Now can we please leave this silly off-topic discussion alone? Feel free to PM me if you want to continue this, but at least let us save the other people watching this thread from the pain of watching this play out.
Are you ok? How much larger a proportion? How much "earlier"? Console manufacturers. That they are literally idiots who haven't learned how to estimate demand despite having it done so many times.
Something something, AMD availability, something:
realAMD/comments/le2wlh
They underestimated demand. Period. They could have done a better job. If me saying that is insulting to you, please grow up. Please, pretty please, show me a quote of me saying that - or anything even remotely to that effect. Seriously. Otherwise, please go away. I mean, seriously. "Literally idiots"? Where? And are you saying that experience actually makes you immune from making poor decisions? Are you actually saying that an experienced person when faced with an unprecedented situation (such as a pandemic, which technically not unprecedented hasn't happened in a century) could not possibly make a slightly bad call? I mean, is your thinking so black and white that me being slightly critical of this must mean that I'm saying they are literally idiots? I honestly don't even know what to do with absurd statements like that.
Also, I don't know what you're trying to say with those numbers... it maybe looks like shipments are picking up somewhat? I frankly have no idea. Still sold out is still sold out.
Oh, and btw:
