Qualcomm already has a chip that can compete that everyone knows about and is coming in under a year so further competition from there is a no brainer. AMD and Nvidia have nothing on their roadmaps, AMD has never brought a custom Arm core to market and Nvidia's last was in 2018. So I just don't see either company bringing out anything Arm client for years to come.
So, you not only think the rumor about them is false, but you also think AMD will stay x86-exclusive until death? In spite of the fact that they previously sold an ARM CPU (Opteron A1100) and designed the K12?
I think AMD will stick with what's working until they see signs that it isn't. Now maybe they don't have more types of x86 cores they're working on and are shifting to Arm, but given their recent track record of improvements it seems unlikely that there isn't more left for them to gain on x86.
I'm not sure I'd consider two failed projects one of which was using Arm designed cores as evidence that a custom core which could compete with their already excellent x86 cores is impending.
Then why'd they supply the SoC for Nintendo Switch?
I used the word
more for a reason, and I'm working on the assumption they'll likely provide the next one as well.
Unless AMD APUs go high enough to hurt Nvidia's dGPU business. Then, Nvidia would be a fool not to respond.
They'd have to be really high performance and relatively cheap to do that, but I do agree with you here.
The hardest thing for successful companies to do is cannibalize their own products with ones that anticipate market trends. Yet, failure to effectively anticipate & respond to the market also spells eventual doom.
I think AMD just sees the writing on the wall. TBH, I expected the transition to post-x86 already to be happening by now.
Unless Arm has something super compelling under wraps the capital expenditure to make a custom core is quite a lot especially while making x86 cores. I think if AMD hadn't made all of the efficiency strides they have we'd have seen a transition. Intel has the low power cores coming with MTL and I could easily see AMD doing their own version of that as well.
I don't forsee a hybrid x86/Arm processor happening so it just doesn't seem likely that AMD would be bringing anything Arm to market until maybe 2026, but more likely 2027+.
