As AMD’s Ryzen 4000 chips enter consumer laptops, the company is also bringing them to corporate PCs.   

The chipmaker today introduced the Ryzen Pro 4000 series, which are designed to provide high performance to thin and light business laptops. The biggest change is the move from 12-nanometer fabrication tech, which was used in last year's Pro line, to AMD's 7-nanometer process. The company has also upgraded the three individual chips in the Pro series with substantially more cores and threads.

For instance, the Ryzen 7 Pro 4750U—the most powerful chip in the batch—now comes with eight cores and 16 threads, or double the count from last year’s model, the Ryzen 7 Pro 3700U. As a result, the processor offers a whopping 132 percent gain in multi-threaded performance in comparison. (However, the increase in single threaded-performance is more modest at only 29 percent.)

For Microsoft applications, AMD’s benchmarks show the Ryzen 7 Pro 4750U can offer a 19 to 77 percent performance gain when compared against last year’s Pro 3700U. But whether the chip can beat Intel’s competing silicon on processing speeds is a little murky. 


AMD vs. Intel benchmark for higher-end chips.

AMD did supply a benchmark that shows the Ryzen 7 Pro 4750U significantly outperforming Intel’s Core i7-10710U processor, which is built with the company’s 10-nanometer manufacturing technology. However, it’s important to note the Core i7-10710U came out in last year’s third quarter, and only features six cores and 12 threads. A better comparison would’ve been to pit AMD’s chip line against Intel’s 10th-generation “Comet-Lake H” processors, which were released last month and can also offer eight cores and 16 threads.

Still, the new Ryzen Pro 4000 series does give PC makers an alternative to sourcing chips for their business notebooks. Lenovo says it's preparing to release five new ThinkPad notebooks with the Pro series in June. The products will include the ThinkPad T14, T14s, X13, L14 and L15 models, which will start at $649.

Expect the Pro series line to also offer long battery life. The newly unveiled processors offer double the performance-per-watt in comparison to last year's chip line. 

The Ryzen 7 Pro 4750U will likely be able to power a premium laptop for over 20 hours on a single charge, AMD adds. The same processors also support full-memory encryption, which can prevent your laptop’s data from being accessed if the hardware is ever physically stolen.

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.
