AMD has confirmed new low-power CPU cores through a Linux kernel patch. The submitted patches add support for these cores in future processors. The move signals a shift toward heterogeneous chip designs.
The patch clearly separates three distinct core types. It distinguishes high-performance, efficiency, and low-power cores. That makes it safe to say future AMD platforms will use all three. The low-power cores handle light workloads specifically.
AMD engineer Vishal Badole explained the purpose of these cores. He said they are designed for background and idle tasks. In those cases, cutting energy use matters more than raw performance. The cores prioritize the lowest possible power draw.
The technical change lives in the CPU topology identification. AMD previously classified cores only as performance and efficiency. The latest patch adds a low-power category to that list. Linux can now tell the three types apart efficiently.
The move follows a path Intel already took. Intel added low-power cores in its SoC tile to offload light tasks. That approach helps prolong laptop battery life. AMD is now going the same route with its own design.
The two companies differ in execution, though. AMD uses the same underlying architecture with a dense, space-optimized variant. Intel instead uses entirely different microarchitectures for its core types. That distinction shapes how each balances power and performance.
AMD disclosed little beyond the patch itself. It did not reveal how the cores differ from today’s Zen 5c cores. It also did not confirm whether they use Zen 5, Zen 6, or a future design. The patch adds no new scheduling logic beyond identifying the category.
Industry watchers link the cores to a rumored Zen 6LP design. Such cores could cut idle power across desktops, laptops, and servers. For businesses running millions of machines, even small savings add up over time.
