AMD is said to combine two different core types for the first time in the Ryzen 8000 processor series. Intel has been demonstrating the principle since the Core i-12000.
AMD is currently said to be designing its own first hybrid processors under the codename Strix Point, which use two different core types. Accordingly, four Zen 5 cores serve as performance cores, while up to eight smaller Zen 5c cores can take over background tasks, for example.
Strix Point is expected to appear for notebooks in 2024 - AMD already confirmed that much in the summer of 2022. The company named the combination of Zen-5 cores, RDNA-3+ graphics unit and AI coprocessor (Ryzen AI) on an official roadmap. Strix Point is expected to come as Ryzen 8000U and Ryzen 8000H.
Former Twitter/X member "Greymon55" already brought a hybrid build at Strix Point into play at the end of 2021 (all posts deleted in the meantime). "Everest" now specifically talks about the four Zen 5 and eight Zen 5c cores. Fittingly, "BenchLeaks" has found an unreleased AMD processor with 24 threads in MilkyWay@home's database.
Cache and clock give way to more cores
AMD has already designed slimmed-down Zen-4c cores in the current generation, but they are exclusively used in the server processors from the Bergamo family. A Zen 4c core is about half the size of a normal Zen 4. In return, AMD has reduced the caches and designed for lower clock frequencies. Both steps save transistors.
Unlike Intel, AMD's efficiency cores are not a completely separate development line. Zen 4 and Zen 4c both handle simultaneous multithreading (SMT) and the same instructions.
For high-end notebooks, AMD allegedly brings the Dragon Range successor Strix Halo as Ryzen 8000HX. According to information from "kopite7kimi", the company wants to use the Zen 5 chiplets of the desktop processors, but this time with an I/O chip specifically designed for notebooks. The latter allegedly integrates a souped-up graphics unit that is supposed to be significantly faster than in the desktop CPUs, combined with up to 16 Zen 5 cores.
