And its not like Intel has any plans to move away from heterogeneous designs anytime soon, even AMD is now doing them and they have their own scheduler issues (X3D on 1/2 CCDs and Zen4+Zen4c).
AMD isn’t really doing anything heterogeneous, pal.
Correct me if I’m wrong here, but apart from the different clock-frequency properties, Zen4c-cores are in fact *identical* to the usual full-grown Zen4-Cores. Zen4c-Cores are barely anything else than a compactly built and neatly rearranged Zen4-Core, without the micro-bumps for the 3D-Cache. The only downside is the lower max clocks, and that’s literally it.
The main reason for AMD introducing any whatsoever Zen4c-Core was the mere fact of their increased power-density (Server-space; Muh, racks!), so solely for space-saving reasons andoverall efficiency and that’s it.
Even the L2-cache is identical, isn’t it?
→ A Zen4c-Core is not a E-Core, as it’s architecturally identical to any Zen4-Core, same IPC.
Same story for the X3D-endabled Cores/Chiplets. Identical apart from a larger cache.
So I don’t really know what you’re actually talking about when erroneously claiming AMD would also have jumped the heterogeneous hype-train. That statement of yours is utter nonsense.
On AMD there’s no heterogeneous mixing in terms of different IPC-/architecture-cores, being different and as such needing to be scheduled accordingly to run properly. Only Intel needs to rely on a heterogeneous-aware (and capable!) scheduler and depends on proper scheduling to NOT kill performance.
Meanwhile, for any mix-and-max AMD Zen4/Zen4c-CPU, it’s fundamentally irrelevant what core a thread is running on, as it doesn’t matter anyway. In fact, the scheduler doesn’t even need to know which core is a usual Zen4 and which is a Zen4c.
AMD’s designs are heterogeneous in terms of different chiplets/configs, yes.
The heterogeneousness you are talking about isn’t even remotely the same as heterogeneousness in terms of Heterogeneous computing (system [on a Chip], that uses multiple types of computing-cores) in terms of different architectures as Intel uses in their Hybrid-SoCs. So no, no heterogeneousness for you!
and this is why amd’s 3d + normal chiplet cpus arent having as hard a time as intels mess. heck even if amd wants to go big little they can have a big chiplet and a little chiplet to avoid many of these problems
