Samsung Starts 7nm Chip Production for Faster Silicon

The new manufacturing process will pave the way for faster, more power efficient smartphone chips. However, Samsung will have to contend with rival TSMC, which has also been securing chip orders with its own 7nm process.

Samsung is starting production of its 7-nanometer chip manufacturing process, which promises to improve the computing speeds and battery life of upcoming smartphones.

With the 7nm process, Samsung will be able to produce chips that are up to 20 percent faster and consume 50 percent less power than chips manufactured with the company's older 10nm process.

In addition, the 7nm process can shrink the chip's size by up to 40 percent, which can help pave the way for slightly thinner smartphones. Outside of mobile devices, the new manufacturing process will also be used to fabricate faster silicon meant for data centres and AI-powered software.

Samsung made the announcement as chip manufacturing rival TSMC has been signing up customers with its own 7nm process. Reportedly, TSMC is producing over 50 chip designs with the technology and has secured orders from Apple, AMD, Nvidia, and Qualcomm.

However, Samsung's 7nm process promises to stand out from the competition by streamlining the chip's manufacturing through a technology called EUV or extreme ultraviolet lithography. Existing chip-making processes require a complex series of steps to write all the tiny features on the silicon. However, Samsung's EUV technology was designed to reduce the processing time and limit manufacturing errors. For customers, this can mean reduced costs and higher chip yields.

Samsung has been researching the EUV technology since the 2000s. Initial production of the 7nm chips will begin in the company's Hwaseong factory in South Korea. The goal is to bring more EUV production online by 2020 to enable increased production of next-generation chip designs.

Over time, Samsung's chip manufacturing might also fuel ARM-based chips entering Windows PCs. In July, the Korean company and ARM announced they were partnering to build 3GHz plus computing for ARM's Cortex-A76 microarchitecture with the 7nm manufacturing process.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
