AMD Confirms New Low-Power CPU Core Type: Zen 6 LP Could Follow Intel's Efficiency Strategy

AMD appears to be making a significant addition to its processor architecture: a new Linux kernel patch reveals that future AMD CPUs could feature a third core type — so-called Low-Power cores, specifically optimized for background and idle tasks.

Three Core Types Instead of Two

Until now, modern AMD processors have offered two core categories: Performance cores for demanding workloads and Efficiency cores (such as the densely packed Zen 5c cores) for general-purpose tasks. With the new Linux patch, AMD is introducing a third category: Low-Power cores.

These cores are identified via CPUID function 0x80000026, specifically through bits [31:28] in the EBX register. AMD engineer Vishal Badole describes them as optimized for background processes and idle states — precisely the scenarios where raw computing performance is irrelevant, but energy efficiency is critical.

A Similar Approach to Intel

Intel has been pursuing a comparable strategy for several processor generations. With Meteor Lake and the upcoming Nova Lake-S, Intel deploys so-called LPE (Low-Power Efficient) cores on a dedicated SoC tile — four cores with four threads that handle background system tasks while the Performance and Efficiency cores on separate tiles manage the actual workloads.

AMD is taking the same path, but with a slightly different philosophy: rather than introducing entirely new microarchitectures, AMD relies on the same fundamental architecture, tuned for maximum energy efficiency through a modified floorplan and specialized clock optimizations. The densely packed Zen 5c cores already demonstrate that AMD applies this principle today.

Zen 6 LP as the Likely Candidate

Although AMD has not yet officially confirmed the exact microarchitecture for the new Low-Power cores, all signs point to a Zen 6 LP variant. The patch itself introduces no new scheduler policies — it simply lays the groundwork for the operating system to correctly detect and classify these core types. Concrete scheduling strategies that make active use of Low-Power cores will likely follow when the corresponding hardware arrives.

What This Means for Businesses

For organizations planning or procuring IT hardware, these developments are relevant for several reasons:

• Operational energy savings: Processors with dedicated Low-Power cores can handle background tasks — such as monitoring services, logging, or system housekeeping — with significantly lower power consumption. This directly impacts operating costs, particularly in server and edge computing environments.

• Better workload distribution: Operating systems will be able to assign tasks even more precisely to the appropriate cores, improving overall performance under load without increasing idle power draw.

• Keep the hardware roadmap in mind: Organizations making procurement decisions today should factor in the upcoming Zen 6 generation. Systems with three core types could prove more economical in energy-intensive environments over the long term.

Conclusion

With this step, AMD is moving closer to the architectural approach Intel has already established with its hybrid processors. The introduction of Low-Power cores is a logical next step toward more energy-efficient processors — for desktops, servers, and mobile platforms alike.
