Tesla Partners with Samsung on New 5Nm Chip for Full Self-Driving, Report Says Fred Lambert - Jan Exclusives Autos Alt. Transport Autonomy Energy Tesla Shop JANUARY 25 Tesla partners with Samsung on new 5nm chip for full self-driving, report says Fred Lambert - Jan. 25th 2021 8:45 am ET @FredericLambert 125 Comments Facebook Twitter Pinterest LinkedIn Reddit Tesla has reportedly partnered with Samsung on a new 5nm chip for full self-driving, according to a new report coming from Korea. Tesla moves to design its own chips Back in 2016, Tesla started building a team of chip architects led by legendary chip designer Jim Keller to develop its own silicon. The goal was to design a super powerful and eEcient chip for self- driving. In 2019, Tesla nally unveiled the chip as part of its Hardware 3.0 (HW 3.0) self-driving computer. They claim a factor of 21 improvement in frame per second processing versus the previous generation Tesla Autopilot hardware, which was powered by Nvidia hardware, while only barely increasing the power consumption. When launching the new chip, CEO Elon Musk announced that Tesla is already working on the next generation of the chip, and they expect it to be three times better than the new chip and roughly two years from production. Tesla’s next-generation self-driving chip A few months ago, there was a report that Tesla planned for its next-generation self-driving chip to use a 7-nanometer process by TSMC, a Taiwan semiconductor company. Now a new report from Korea states that Tesla is partnering with Samsung on a 5-nanometer chip for self-driving (via Asia-E and translated from Korean): According to related industries on the 25th, the Samsung Electronics Foundry Division is currently conducting research and development (R&D) on 5nm-class system semiconductors to be mounted on Tesla autonomous vehicles. The 5nm semiconductor applied with the extreme ultraviolet (EUV) process is a high-tech product that only a small number of companies such as Samsung Electronics and TSMC can produce worldwide. Samsung is already Tesla’s partner for the production of its current self-driving chips in its hardware 3.0 computer. However, that chip is based on a 14-nm technology. 5-nm chips are a more recent technology that only started to make it into commercial products last year. They are found in some of the latest smartphones, like Apple’s iPhone 12. The latest report on Tesla’s new chips stated that mass production was planned for Q4 2021 – meaning that we aren’t likely to see those chips inside Tesla production vehicles until 2022.

Name welsh_boy • 2 days ago Some thoughts what the shift from 14nm to 5nm and revised architecture may enable: less power consumption less cost (per chip) merging of the two redundant processors to a single die (see PCBA picture in the article) bring the media display CPU and GPU on die bring the cellular modem on die bring high speed ram on die more processing for less frequent hand offs to driver support for new algorithms / compute efficiency (see less power consumption) support for the rumored hi-res front radar? support for additional cameras / sensors on yet to be released models (roadster, cybertruck / semi / ???) 34 * + • Reply • Share › watchingfromabove % welsh_boy • 2 days ago Good comments, welsh boy. I agree with those except the one about putting the redundant processors on a chip. It might make sense to put two core equivalents on the same chip and have quad redundancy by adding another package since the point is to make the system fault tolerant and if one of the processors fail and dies bringing the chip down, the system still works. That said, to do fault tolerance right, There would actually be three boards with different power supplies, I/O paths, in different physical locations in the car, all working fully independent and voting (possibly overkill). This is a similar architecture to what the space shuttle used for the primary GPCs which the shuttle was dependent upon. 17 * + • Reply • Share › Joseph Brown % watchingfromabove • a day ago It is also similar to what the Dragon does, as well. 6 * + • Reply • Share › Commenter4376 % watchingfromabove • 9 hours ago They're not going to merge the MCU with the self driving chip though. They are already in talks with AMD for the next- gen MCU which will likely approach PS5 / Xbox gaming console levels of power. 1 * + • Reply • Share › Anthony % welsh_boy • a day ago There is no way you can put all that stuff on one single die. Its a terrible idea. 1. Put the RAM on package like the new Apple M1 chip maybe. It would seem to be a good approach. 2. Leave MCU CPU/GPU alone. It brings no value to the FSD system to have this here. Just connect over a high speed bus and let the MCU do its thing. 3. Leave cell modem and RF front end alone. Again, those chips don't bring any value for Tesla to integrate into FSD. 2 * + • Reply • Share › alan % welsh_boy • a day ago and if you bring the world on on die your fault rate will go up to the moon , some of the things your mention should be some should not I would not bring modem or ram on die as one is going to change and the other can be cached . 3 * + 2 • Reply • Share › phubbing % welsh_boy • 19 hours ago sounds like #apple #m1 :)) unified memory pool ;)) well very nice :) 1 * + • Reply • Share › Stephan % welsh_boy • 20 hours ago Having two chips could very well be a necessy redundancy by design. Don't forget that the hardwade is highly functional saftey relevant. At least I would be more than happy that if I use FSD and one chip fails there is another one that can stopp the car in a controlled way. Atm everything is speculation. Half a year ago more pointed to TSMC producing processors for Dojo than for FSD. At this point w/o further spec (especially chip size) there is an almost equal chance that it is about the next controller for the infotainment device. * + • Reply • Share › AS3 % welsh_boy • a day ago I agree with all the potential additions you mentioned, except "support for the rumored hi-res front radar" and "support for additional cameras" (for the Roadster or Cybertruck). Tesla will make sure to keep the same 8 cameras, 1 radar, and 12 ultrasonic sensor inputs into the SoC. Nothing special needs to be made, for the new radar. Tesla is about efficiency, so it is not likely that extra equipment will be added, for the Roadster or Cybertruck. In fact, the Semi- truck has a huge camera reduction, from the original concept (so far). * + • Reply • Share › RoadRunner48 % AS3 • a day ago The article here the other day about a high-res radar was for an internal radar, something to scan the interior of the passenger cabin. Sadly, it was not anything about a new sensor to scan the environment, which is what Tesla needs to make any meaningful advance in Autopilot toward Level 4 autonomy. * + • Reply • Share › Paul Vining % RoadRunner48 • a day ago Musk in an interview earlier this year in Germany said he already has reached Level 5 autonomy... 1 * + 1 • Reply • Share › Dan Frederiksen % Paul Vining • 19 hours ago Musk doesn't necessarily always tell the complete truth. Level 5 they most certainly don't have. 1 * + • Reply • Share › kbm3 % Paul Vining • 14 hours ago Nope. * + • Reply • Share › Alaa • 2 days ago 5nm means faster and consumes less energy 9 * + • Reply • Share › AS3 % Alaa • a day ago Well, it means less energy consumed, at least (if everything else stays the same). The only main way to get faster, without a clock increase, is to bring the memory a lot closer to the CPUs (decrease latency). I do expect clock increases and/or more parallel processing. They will likely work within the current power draw limits (maybe even a little bit more power draw). 1 * + • Reply • Share › Old_ISP % AS3 • an hour ago Actually, the slew rate is dependent on the saturation. So the smaller, the faster it saturates. * + • Reply • Share › Belland _Dog % Alaa • 2 days ago Yes, that's what a generational leap usually does (or at least what they strive to do, otherwise there is no reason for the new process). Though ofc it can range wildly with different architectures.

  • TSMC Investement in Arizona
    Michael R. Splinter Chairman of the Board Senator Robert Menendez Senator Lisa A. Murkowski Honorary Co-Chair Honorary Co-Chair Rupert J. Hammond-Chambers President INTERNAL COMMENTARY: THE STRATEGIC IMPORTANCE OF THE TSMC ARIZONA INVESTMENT MAY 15, 2020 RUPERT J. HAMMOND-CHAMBERS PRESIDENT Taiwan Semiconductor Manufacturing Company (TSMC) is the world’s largest contract chip manufacturer. A key link in the global technology supply chain, it is the most important company most people have never heard of. TSMC, based in Taiwan, is now doubling down on its relationship with the United States in a big way. On Friday, May 15, 2020 TSMC announced the most important technology news of the year; the company committed to building a cutting-edge 5nm fabrication plant (fab) to produce semiconductor chips in Arizona. Its U.S. customers for the chips produced here will not only include U.S. tech companies, but will also include the Pentagon, defense contractors, and the national security community. The visionary founder of TSMC, Morris Chang, imagined a world where fabless semiconductor companies would absorb the financial burden of designing chips, but would outsource their actual production to his TSMC. His vision created a monster that dominates the sector he created - the foundry manufacturing sector – making almost 50% of all chips produced by foundries globally. TSMC’s state-of-the-art process technology and CAPEX investment of approximately US$15 billion/year ensures that it has few, if any, peers. Successive Taiwan governments have continued to nurture TSMC through prioritized access to land, power, and water, thereby allowing it to serve as the beating heart of Taiwan’s technology miracle.

  • Semiconductors: a Changing of the Guard
    Semiconductors: A Changing of the Guard Richard Spalton MA, CFA Investment Manager Semiconductors: A Changing of the Guard “While an early chip from the 1970s could fit thousands of micrometre-sized transistors, today’s most advanced chips are a complex web of billions of transistors, the smallest of which are just 10nm. To get some idea of how small that is: your fingernails grew 10nm in the time it took to read the previous sentence.”1 Background One of the key enablers of technological progress has been the constantly shrinking size of the transistors on semiconductor chips. Smaller transistors mean that the same number of computations can be completed faster, more efficiently and at lower cost. This concept was famously outlined by Gordon Moore, co-founder of Intel, who in 1965 wrote what became known as Moore’s Law. The manufacturing process for a particular size of transistor is called a process node. Shifting to a new node is highly complex and involves significant capital expenditure. In July 2020 Intel announced that their transition to the 7 nanometre node was running a year behind schedule. This delay will have a significant impact on Intel and its competitors. This announcement marks a changing of the guard in the semiconductor market, with leadership shifting away from Intel towards Taiwan Semiconductor Manufacturing Company (TSMC) and Samsung Electronics. Scale Matters Assessing the future prospects of a company requires an assessment of its industry. Manufacturing semiconductors is highly capital intensive – the industry spends USD 100bn per annum on capital expenditure. Companies also need to spend substantial amounts on R&D because each process node is more complex than the last.

  • Needham's Semiconductor Expertise What Does The
    The Growth Factor - Commentary by John Barr, [email protected] June 23, 2021 - Vol. 32 The Opportunity We See in Semiconductor Manufacturing (6 minute read) 2020 brought an unprecedented economic shutdown. The pandemic accelerated trends that we have been focused on for a long me; we call this the Great Digital and Life Sciences Acceleration. I would like to zero in on the opportunities in semiconductor manufacturing. I’ve long felt the semiconductor industry has moved beyond a cyclical, PC-driven industry to one of strategic importance. The confluence of manufacturing semiconductors for automotive, data center, machine learning, and remote work electronic systems; remaking the supply chain, and securing supplies for geopolitical needs have created a positive scenario for semiconductor manufacturing technology companies. Needham's Semiconductor Expertise Needham Funds have been owners of semiconductor manufacturing companies since our start in 1996. Needham Funds are an affiliate of Needham & Company, which has completed over 580 underwritings and M&A transactions for semiconductor companies since 1985. Addionally, prior to my Wall Street career, I spent 12 years in sales and markeng for Electronic Design Automaon companies, selling to semiconductor and electronic systems companies. I also spent 8 years as a sell-side senior research analyst following semiconductor design and technical soware companies. I served on the board of directors of venture capital-backed Coventor, Inc., which provided simulaon and modeling soluons for semiconductor process technology and was sold to Lam Research, Inc. in 2017.

  • PART I: People & Strategy
    By Ken Luskin [email protected] October 28, 2014 PART I: People & Strategy The Brilliance of Steve Jobs was in building a team of geniuses Virtually everyone in the world knows that Steve Jobs was the driving force behind the success of Apple. Unfortunately, few of them understand that without the team of technical gurus Jobs assembled, his visions would not have become reality. Without a Microprocessor Brain, the iPhone would not exist Inside every “smart” computing device is a microprocessor, considered the brains of the device. When Jobs was creating what is now known as the iPhone, he needed a special microprocessor, which could make it through the day without draining the battery. Jobs first approached Intel, the company that was supplying the microprocessors for the entire MAC line. Intel was not interested in supplying a relatively low cost mobile chip, because the bean counters and FAB guys had no vision. So, Jobs built a team of top mobile microproprocessor engineers, licensed the ARM architecture, and created a chip that became the brains of the iPhone and iPad. Apple buys P.A. Semiconductor in 2008 to keep Apple’s microprocessors on the cutting edge With this acquisition Apple received a group of highly innovative engineers, including ex AMD employee Jim Keller. From a VentureBeat article: “Keller spearheaded the development of Apple’s custom mobile processors — including the A4 in the iPhone 4, the A5 in the iPhone 4S and iPad 2, and the A5X in the new iPad — all of which have managed to keep Apple’s mobile devices on the cutting edge.

  • TSMC'schipdominanceis Expectedtocontinueasit Plans$100Bexpansion
    JUN 21 Gadjo Sevilla TSMC’s chip dominance is expected to continue as it plans $100B expansion Article The news: As most of the world relies on chip production from TSMC, the global shortage and the lack of a diversified semiconductor supply chain pose risks to the global economy, per The Wall Street Journal. How we got here: TSMC’s microchips are in billions of products ranging from iPhones, PCs, smart home devices, and IoT sensors. TSMC produces high-performance processors Copyright © 2021, Insider Intelligence Inc. All rights reserved. Page 1 designed by companies like Apple and Qualcomm for the latest smartphones and computers, but it also dominates the market for less-sophisticated microcontrollers used for automating smart cars and smart home appliances. Heavy reliance on a single chip producer is exposing risks to the global economy, a reality that’s only become clearer amid the global semiconductor shortage and which is resulting in higher costs being shouldered by consumers. Surging demand for electronics during the pandemic overwhelmed the semiconductor industry and led to a global shortage expected to last another 18 months, per CNBC. China, Europe, and the US have started to invest in various chip foundries to satisfy future demand and better diversify supply chains, but these eorts will have no eect on the current shortage. The bigger picture: Several chip manufacturers are building chip factories in the US, the scale of investment pales beside TSMC’s planned expansion, which will cost $100 billion over the next three years. TSMC’s investment is a quarter of the entire industry’s capital spending per VLSI Research.

  • Supplier Clean Energy April 2019 Program Update
    Supplier Clean Energy April 2019 Program Update Apple is committed to addressing climate change and increasing the use of renewable energy. We launched the Supplier Clean Energy Program in October 2015 to advance the use of clean energy in our supply chain. We continue to demonstrate that powering operations with clean energy is good, not just for the environment, but for business, too. That’s why we’ve worked hard to source 100 percent renewable energy for all of Apple’s global facilities. When companies join the Supplier Clean Energy Program, they make a clear statement to Apple and to the broader business community that they share Apple’s beliefs and are ready to lead. Manufacturing is energy intensive and historically has relied heavily on fossil fuels. So we partner with our suppliers to ensure that clean energy is cost competitive and readily accessible in the markets where they operate. These efforts are helping to reduce product-related carbon emissions, create a more resilient supply chain, and contribute to healthier communities—while also paving the way for others to follow. Supplier Clean Energy Program The Supplier Clean Energy Program is integral to reducing Apple’s overall emissions. Manufacturing makes up 74 percent of Apple’s carbon footprint. And most of those emissions are from the electricity used to make the parts in our products. So we’re focused on increasing energy efficiency at supplier facilities, and then on transitioning suppliers to clean, renewable energy. As a first step, we’re partnering with our suppliers to generate and source more than 4 gigawatts of new clean energy in Apple’s global supply chain by 2020.
