On: New SiFive RISC-V core P650 with 40% IPC increase

This is a real possibility, albeit a sad one.

No amount of FUD will save ARM. Only pivoting into a different business model could.

Honestly, ARM is fine. They're no longer the only game in town, but they've still got a huge head start.

[snvzz → duskwuff]

They'll be fine if they focus on their microarchitectures rather than the ISA (where IMHO they've already lost), and make the process for obtaining a license much more streamlined; I've heard it takes no less than 18 months of long negotiations to license anythin from ARM. That's not sustainable now that there's competition.

[duskwuff → snvzz]

That's already where their focus is. Most of ARM's customers are licensing specific cores from ARM, not the ISA as a whole.

> where IMHO they've already lost

Given M1, Graviton etc etc that’s a bold statement.

[snvzz → klelatti]

High performance implementations are possible even with bad ISAs, given enough resources.

x86-64 is much worse than ARM. It's a literal clusterfuck. And yet.

A high performance implementation of ARM, which is a much better ISA than x86-64, was something expected to happen sooner or later. It did not surprise me.

[klelatti → snvzz]

Fair enough but I’m still not sure why you think the Arm ISA has ‘lost’?
