It might be time for Intel and AMD to join their efforts to be relevant in PC segment.
There's a rumored equivalent SoC from AMD, planned for a 2025 launch. The rumor said it's aimed at laptops, so basically an answer to Snapdragon X.
I think Intel has been leaning more in the direction of RISC-V, but that would only be relevant for embedded, at this point, and soon expanding to server/cloud. The thing is, ARM is rapidly dominating the cloud,
today. So, even if Windows on ARM doesn't displace x86, it's not as if it'd be a waste of effort to build a competitive ARM core, because you can still sell it into the server market.
Also, once you have a high-performance ARM core, porting it to run RISC-V probably isn't very hard. So, I think it's smart to jump on the ARM bandwagon today, but then keep a close eye on the RISC-V market and jump in, as soon as it starts to get some real momentum in server market.
