AMD mobile Ryzen 5000: specs and features

If the latest crop of rumors have any basis, AMD’s hotly anticipated Ryzen 5000 mobile CPU family could mix chips from old and new architectures, making shopping for a Ryzen-based laptop even more confusing.

According to a collection of leaks and reports, the mobile Ryzen 5000U series of APUs (CPUs with integrated graphics cores inside) are expected to include both “Lucienne” and “Cezanne” cores. Lucienne chips will reportedly be designed around AMD’s older Zen 2 architecture, and Cezanne around the more powerful Zen 3 architecture. 

AMD declined to comment on what it called rumors and speculation. Nevertheless, the possibilities add some interest to what’s expected to be a busy round of announcements from AMD at the upcoming virtual CES in January. All the rumors we’ve heard are detailed below, from product names to clandestine (and possibly falsified) benchmarks.

When could AMD announce mobile Ryzen 5000?

CES has already confirmed that AMD chief executive Lisa Su will give a keynote address at 8:00 a.m. Pacific Time on January 12, roughly a year after AMD released the mobile Ryzen 4000 family at the same event. An announcement of the next-gen mobile Ryzen 5000 family seems more than likely. Ryzen 5000 H-series chips are reportedly on tap, along with the lower-power Ryzen 5000 U-series chips.

AMD’s mobile Ryzen 4000 crushed Intel’s Core processors, and the desktop version of the Ryzen 5000 appeared as strong or stronger than its Intel rivals. Expectations for Ryzen 5000 mobile CPUs are therefore very high, which makes the prospect of mixing older and newer architectures all the more intriguing. 

What CPUs will be in the mobile Ryzen 5000 family?

Based on leaks and other reports, there are six Ryzen 5xxxU chips and four Ryzen 5000 H-series chips forthcoming, versus last year’s five Ryzen 4000 U-series chips and just two H-series chips. 

The sources for these rumors include a benchmark for Ashes of the Singularity, via WCCFtech; specs published to Twitter, and a series of retailer configurations published by leaker momomo_us, again to Twitter and compiled by VideoCardz.

  • Ryzen 7 5800U (Zen 3): 8 cores/16 threads; 1.8GHz base/4.40GHz boost; 8 CUs
  • Ryzen 7 5700U (Zen 2): 8 cores/16 threads; 1.8GHz base/4.3GHz boost; 8 CUs
  • Ryzen 5 5600U (Zen 3): 6 cores/12 threads; 2.3GHz base/4.3GHz boost; 7 CUs
  • Ryzen 5 5500U (Zen 2): 6 cores/12 threads; 2.1GHz base/4.0GHz boost; 7 CUs
  • Ryzen 3 5400U(Zen 3): 4 cores/8 threads; 2.6GHz base/4.0GHz boost; 6 CUs
  • Ryzen 3 5200U (Zen 2): 4 cores/8 threads; 2.6GHz base/3.85GHz boost; 6 CUs

The most powerful gaming laptops will, of course, be based on the H-series parts, with 35W to 45W power envelopes. AMD’s mobile Ryzen 4000 series offered just two H-series. If the Ryzen 5000 rumors are accurate, AMD will offer two H-series parts as well as more powerful -HS and -HX options. They will all be part of the Cezanne/Zen 3 family.
