chiplet: A small piece of silicon that can be combined with other chiplets to create a larger, more complex system.

The graph in figure below depicts percentage yield with respect to chip area. The term “Chiplet” is relatively new and has only been used for about five years or so. It was originally coined by researchers and scientists at the University of Michigan as they began investigating ways to improve computer chips’ design, efficiency, and functionality.

In the last 24 months or so we have seen AMD, Intel, TSMC, and Samsung adopt chiplet solutions. Intel has developed AIB and MDIO, TSMC has developed Lipincon, and the Open Domain-Specific Architecture has created the CDX to standardize design. Chiplets from different sources MUST have standardized interfaces/communication protocols. The first commercial entity I saw express similar ideas was AMD’s Bryan Black at Georgia Tech’s Global Interposer Conference in 2011. “The naming of new technologies can be difficult and often inaccurate. Anyhow, it became clear that the chiplet definition needs to be reviewed until it is understood by everyone. For those of you who feel this is a waste of your time because you are already educated, my apologies.

The computing architecture has higher reconfigurability and scalability compared with the traditional SoC-based computing system. It requires co-design of software and hardware, and there is a certain design complexity. Fortunately, there are already solutions for these problems; therefore, the Chiplet-based reconfigurable computing system design technology has obvious technical advantages.

How Chiplets Assemble Into The Most Advanced Socs

There are also benefits in chip design, allowing companies to shrink down critical components to new, smaller processing nodes without having to shrink down the entirety of the SoC to match. Lastly, combining chiplets together lets companies make bigger chips than they could with a single, monolithic design. Another way in which chiplets can help reduce costs is by allowing manufacturers to use a mix-and-match approach to creating SoCs. Rather than designing and manufacturing a new chip from scratch for each new product, manufacturers can instead use a combination of pre-existing chiplets to create the desired SoC, which can be faster and more cost-effective. This can be particularly useful for companies that need to bring products to market quickly and need to be able to make rapid changes to their SoCs to meet changing market demands. The intense competition of moving to the next process node and designing more sophisticated larger SoCs has monopolized each layer of the semiconductor value chain.

It has gathered much early interest, but it is going to be a long journey. These are just a few examples of companies that are using chiplet technology in the market today. There are likely many other companies that are also using this approach in their products. The flexibility offered by chiplets also provides important design and development benefits. Because they can be customized and upgraded easily, chiplets allow manufacturers to quickly adapt to changing market conditions or new technological developments. They also simplify the production process by reducing the steps required to design and manufacture customized SoCs.

Besides, SiP designers will also have the option of mixing and matching available chiplets. As a result, complexity and workload will likely be migrating from design and fabrication to packaging. As a result, the packaging layer of the value chain will gain higher traction. Hence, fabless IC companies will find OSAT firms increasingly more relevant to them. In an extreme case, they may successfully design SiPs using only off-the-shelf chiplets and directly going to OSAT firms to interconnect and package them as per the design.

Chiplet Standards

So those kinds of capabilities — both building new services, deepening our feature set within existing services, and integrating across our services – are all really important areas that we’ll continue to invest in. We continue to both release new services because customers need them and they ask us for them and, at the same time, we’ve put tremendous effort into adding new capabilities inside of the existing services that we’ve already built. There’s so much data in the world, and the amount of it continues to explode. A lot of people are drowning in their data and don’t know how to use it to make decisions. Other organizations have figured out how to use these very powerful technologies to really gain insights rapidly from their data. The number of customers who are now deeply deployed on AWS, deployed in the cloud, in a way that’s fundamental to their business and fundamental to their success surprised me.

  • A lot of benefits of scale for our customers, including the expertise that they develop on learning one stack and really getting expert, rather than dividing up their expertise and having to go back to basics on the next parallel stack.
  • While there are some disadvantages with this particular design but they are mostly overshadowed by the many advantages.
  • Chiplet technology can be seen as a way to extend Moore’s Law and continue the trend of improving performance and reducing costs in the semiconductor industry.
  • The power management chip consists of a combination of capacitors and through silicon vias.

So, in general, there’s significant cost savings by running on AWS, and that’s what our customers are focused on. But whether the industry comes together in 2025 or 2026, chiplets are the future of processors — at least for the moment. Data centers consume a massive amount of the world’s energy, and that consumption will only increase as Mark Zuckerberg attempts to manifest his version of the metaverse, and, in the nearer term, more aspects of our lives turn digital. Mixing and matching chiplets would also enable AMD and Intel to create custom products for large customers that have specific needs. Accelerated computing, which is commonly deployed to tackle AI compute tasks, is low-hanging fruit to Das Sharma. Should one customer need a chip for a specific type of AI, Intel could substitute a general purpose accelerator for something more specialized.

A lot of customers are using containerized workloads now, and one of the big container technologies is Kubernetes. So we’re very committed to providing hybrid capabilities, including running on premises, including running in other clouds, and making the world as easy and as cost-efficient as possible for customers. That being said, many customers are in a hybrid state, where they run IT in different environments.
