In excess of the earlier 4-5 months, we’ve mentioned repeated item shortages impacting just about every piece of substantial-conclude Computer system or gaming hardware presently on the market. A single of the a lot more fascinating aspects of the predicament has been the way it has strike every person: Samsung-developed Nvidia GPUs are tough to come across, but so are TSMC-constructed AMD GPUs. AMD CPU price ranges and availability has been all over the map. The PS5 and Xbox Series S|X have been in and out of stock.
Given that AMD doesn’t construct its possess hardware, a great deal of eyeballs have targeted on TSMC during this period of time, but it hasn’t been obvious if which is in which the true dilemma lies. One particular clarification is that big desire + ramping up new layouts have developed bottlenecks in the sector. A further — a single we have not dug into substantially, thanks to not knowing exactly where the difficulty may well be coming from — is that there is an upstream challenge with a various corporation in the chip manufacturing provide chain that is feeding this challenge.
Studies from drop, 2020 suggested that TSMC was functioning by a scarcity of ABF substrate. ABF (Ajinomoto Establish-up Movie) is a resin that insulates modern ICs and resists growth and contraction based on modifications in temperature. Connections bridging the gap involving the nanoscale (IC) and millimeter-scale (packaging) are made by way of an ABF layer, as revealed underneath:
ABF is unbelievably vital to the chip-packaging method, and an ongoing scarcity is hitting pretty significantly absolutely everyone who employs highly developed packaging benchmarks. This could healthy our criteria for an vital piece of the all round clarification of what’s going on, because this is not an difficulty that would effects just Nvidia, AMD, Intel, or any other single corporation. If TSMC simply cannot buy enough of it, the effect could ripple out throughout the current market, hitting a variety of corporations. Apple, Qualcomm, and Samsung all use ABF as very well. DigiTimes described on a lack at minimum as early as June 2020 and claimed it could widen and worsen in 2021. That prediction seems to have borne fruit.
Low yields on GDDR6 have also been blamed for GPU shortages, nevertheless yet again, it is not very clear precisely which part shortages are driving which problems. But it is clear this goes over and above yield difficulties, which helps make perception — we have listened to rumors of lower 8N yields at Samsung, but nothing about any equivalents at TSMC. We also know that AMD has been transport 7nm silicon out of TSMC considering the fact that mid-2019, implying that the node ought to be pretty mature by now, even for significant-electricity desktop chips and GPUs. The fact that we’re observing world-wide issues does counsel there may be further variables in engage in.
Also, the crypto sector is exploding all over again, which is likely to assistance particularly no one particular and very little when it will come to getting a remedy to ongoing shortages. A report from HardwareTimes promises that Sony and Microsoft have reserved up to 80 p.c of AMD’s 7nm generation for consoles. Presumably, this is a reference to 80 percent of the allocation AMD purchases from TSMC, as opposed to an implication that either company purchased 7nm fab house “from” AMD (AMD is a chip designer, not a maker). A predicament in which AMD allotted 80 p.c of its creation to consoles is not as ridiculous as it seems if you believe the agreement was virtually undoubtedly a short-lived 1, intended to cover only the original launch volumes. Of training course, the continual shortages and ongoing need have confirmed the consoles would remain scorching-ticket items for for a longer time. Since this has been the scenario with each other large-conclude merchandise, we’re generally caught in the significant-tech equivalent of sixteen persons making an attempt to go by means of a doorway at the precise very same time. Winners? No one. Losers? Everyone striving to get components devoid of marketing a kidney and/or producing a Faustian bargain in excess of delivery time frames.
TSMC’s big suppliers for ABF are all rumored to be suffering from ongoing shortages. There are rumors that AMD just cannot presently meet up with desire for notebooks since of the ABF issue and that the issue could worsen in Q3 2021 when Zen 3 notebooks occur to current market. Up until eventually now, we have heard a great deal of rumors that the shortages would ease in March-April 2021, but if the ABF angle is genuine, it could acquire lengthier.
