Comment on AMD starts bringing its own tiny CPU cores to new Ryzen 7040 laptop chips

Enlarge / Unlike Intel's E-cores, AMD's Zen 4c supports all the same capabilities as Zen 4, just in a smaller package with lower clock speeds. (credit: AMD) AMD sells a lot of 7000-series Ryzen processors for laptops, but the most advanced ones are in the 7040 family. These are the only chips that combine AMD's latest Zen 4 CPU architecture and its latest RDNA 3 graphics cores, whereas other 7000-series laptop chips mix and match various older CPU and GPU architectures. Today, the company is announcing two new Ryzen 7040U-series chips for thin and light laptops, but with a twist: They combine regular Zen 4 CPU cores with "Zen 4c" cores that are designed to save space rather than hit high clock speeds (via AnandTech).
