The other option is to use the best available x86 mobile CPUs, and these at the moment seem to be from AMD. From what I've seen even current AMD CPUs are competitive with M1. Ryzen 4900HS has a fair lead in multicore performance and close single threaded. Of course, all this at a higher power and fans running as a jet engine. But AMD is one process node behind, and one architectural node behind their desktops (Zen 2 on 7nm). So, OEMs can use the perf gains from both the advancements to lower the TDP a bit,(ex 10%), put a larger battery. And this can result in a competitive product, even with the rumored M1X, since Ryzens already have the multicore lead. That being said, from I read, the next mobile Ryzens will be 5000 series, released in a month, at 7nm. So only a ~20% IPC uplift is expected. Also probably TSMC's 7nm improved a bit. Nothing to scoff at, but not as exciting as a new process node. Anyway, we'll see soon enough. |
