So, which companies currently make these chips, and where are they located? The above infographic uses data from TrendForce to break down the top 10 semiconductor companies by country and market share.
The Biggest Semiconductor Companies
Before diving into the companies, it’s important to have context on their business. Also known as foundries, these semiconductor companies specialize in the fabrication or production of chips. “Fabless” chip makers—companies that design their chips and supply hardware but do not have fabrication plants—outsource chip production to foundries, primarily in Asia. Taiwan, China, and South Korea combine for roughly 87% of the global foundry market. Here’s how it breaks down: TSMC, short for Taiwan Semiconductor Manufacturing Company, is by far the world’s largest chip manufacturer. It’s also the sixth most valuable company in the world with a market cap of over $600 billion, and supplies chips to the likes of Apple, Intel, and Nvidia. TSMC and Samsung are the only companies capable of producing today’s most advanced 5-nanometer chips that go into iPhones. However, the Taiwanese company is one step ahead and set to produce its 3-nanometer chips in 2022, offering the most advanced foundry technology. Other companies on the list include China’s largest chipmaker SMIC, one of the 60 Chinese companies blacklisted by the U.S. in 2020. On a country level, Taiwan accounts for 63% of the foundry market, followed by South Korea with 18%. In both countries, the majority of the market share belongs to a single company.
The 2021 Semiconductor Shortage
With the adoption of 5G devices and other new technologies, chips have been in high demand. While pandemic-induced shutdowns have hampered supply, the demand for chips has continued surging with reopening economies. The resulting chip shortage has rattled several industries with lead times—the gap between when a semiconductor is ordered and when it is delivered is at a record high of 22 weeks. The chip shortage is a boon to semiconductor companies, but downstream firms are struggling. Global automakers are set to make 7.7 million fewer cars in 2021, which translates into a $210 billion hit to their revenues. Consumer electronics have taken a blow as well, with popular products like the Playstation 5 console in short supply. New chip factories take years to build, in addition to billions of dollars. With many analysts expecting the shortage to last through 2023, it’ll be interesting to see how chipmakers respond, especially if demand continues to rise. Source: TrendForce on Today’s connected cars come stocked with as many as 200 onboard sensors, tracking everything from engine temperature to seatbelt status. And all those sensors create reams of data, which will increase exponentially as the autonomous driving revolution gathers pace. With carmakers planning on uploading 50-70% of that data, this has serious implications for policymakers, manufacturers, and local network infrastructure. In this visualization from our sponsor Global X ETFs, we ask the question: will connected cars break the internet?
Data is a Plural Noun
Just how much data could it possibly be? There are lots of estimates out there, from as much as 450 TB per day for robotaxis, to as little as 0.383 TB per hour for a minimally connected car. This visualization adds up the outputs from sensors found in a typical connected car of the future, with at least some self-driving capabilities. The focus is on the kinds of sensors that an automated vehicle might use, because these are the data hogs. Sensors like the one that turns on your check-oil-light probably doesn’t produce that much data. But a 4K camera at 30 frames a second, on the other hand, produces 5.4 TB per hour. All together, you could have somewhere between 1.4 TB and 19 TB per hour. Given that U.S. drivers spend 17,600 minutes driving per year, a vehicle could produce between 380 and 5,100 TB every year. To put that upper range into perspective, the largest commercially available computer storage—the 100 TB SSD Exadrive from Nimbus—would be full in 5 hours. A standard Blu-ray disc (50 GB) would be full in under 2 seconds.
Lag is a Drag
The problem is twofold. In the first place, the internet is better at downloading than uploading. And this makes sense when you think about it. How often are you uploading a video, versus downloading or streaming one? Average global mobile download speeds were 30.78 MB/s in July 2022, against 8.55 MB/s for uploads. Fixed broadband is much higher of course, but no one is suggesting that you connect really, really long network cables to moving vehicles.
Ultimately, there isn’t enough bandwidth to go around. Consider the types of data traffic that a connected car could produce:
Vehicle-to-vehicle (V2V) Vehicle-to-grid (V2G) Vehicles-to-people (V2P) Vehicles-to-infrastructure (V2I) Vehicles-to-everything (V2E)
The network just won’t be able to handle it.
Moreover, lag needs to be relatively non-existent for roads to be safe. If a traffic camera detects that another car has run a red light and is about to t-bone you, that message needs to get to you right now, not in a few seconds.
Full to the Gunwales
The second problem is storage. Just where is all this data supposed to go? In 2021, total global data storage capacity was 8 zettabytes (ZB) and is set to double to 16 ZB by 2025.
One study predicted that connected cars could be producing up to 10 exabytes per month, a thousand-fold increase over current data volumes.
At that rate, 8 ZB will be full in 2.2 years, which seems like a long time until you consider that we still need a place to put the rest of our data too.
At the Bleeding Edge
Fortunately, not all of that data needs to be uploaded. As already noted, automakers are only interested in uploading some of that. Also, privacy legislation in some jurisdictions may not allow highly personal data, like a car’s exact location, to be shared with manufacturers.
Uploading could also move to off-peak hours to even out demand on network infrastructure. Plug in your EV at the end of the day to charge, and upload data in the evening, when network traffic is down. This would be good for maintenance logs, but less useful for the kind of real-time data discussed above.
For that, Edge Computing could hold the answer. The Automotive Edge Computing Consortium has a plan for a next generation network based on distributed computing on localized networks. Storage and computing resources stay closer to the data source—the connected car—to improve response times and reduce bandwidth loads.
Invest in the Future of Road Transport
By 2030, 95% of new vehicles sold will be connected vehicles, up from 50% today, and companies are racing to meet the challenge, creating investing opportunities.
