AMD reportedly working on its heterogeneous CPU design

Intel will soon be releasing its 12th Gen Core Alder Lake processors for desktop and laptop systems. It will be implementing the high-efficiency (small) and high-performance (big) core in its new hybrid architecture. However, in modern desktop systems power efficiency is not paid much attention to as it hasn’t been a concern yet.

But, Microsoft has announced that its upcoming windows will feature a new task scheduling method for heterogeneous computing, and it aligns with Intel’s Alder Lake launch.

Now coming to Intel’s rival AMD, there’s no confirmation that AMD is working on such processor design. However, according to a new leak, we have received a codename ‘Strix Point‘, which is associated with Zen5 based APU, supposedly also featuring smaller cores known as Zen4D.


AMD published its patent on ‘task transition between heterogeneous processors’ just two days ago. Originally the patent was filed in December 2019, which suggests that AMD has been working on this technology for a long time. The patent covers the most important engineering problem of heterogeneous computing.

According to sources, AMD’s design will have the CPU relocate tasks between the cores based on one or multiple metrics. It will include execution time of the task, a requirement of using memory at maximal performance state, direct access to memory, or a metric of average idle state threshold.

Sources indicate that as of this moment, it will be the Ryzen 8000 series “Strix Point” to implement heterogeneous architecture with 3nm Zen5 cores combined with Zen4D on a single package. However, by the time AMD’s heterogeneous CPUs/APUs are available, Intel would have already beaten the red team to the punch. It will be interesting to see the two rivals battle it out for the next-gen crown.
