A 64-bit CPU core licensed under that can actually boot

is getting more feasible even to the core!

– Our goal is >4 IPC (average) with >97% branch prediction and lots of cache, deep out-of-order pipelines and speculative execution for managing cache and branch miss latency
– General long term goal is a high end server class CPU, 5GHz+, multithreaded, 100+ instructions in flight at any one time

that reads like:

"I'm not sure we need to apply any learning from Spectre & Meltdown, we really just want a big CPU like Intel has, that goes vroom. but being GPL, it won't be controlled by Intel. It can instead be controlled by all other big corps."

@meena
It is true out-of-order execution is ripe for exploits and I am both surprised and not at all surprised to see it implemented in cores. The speed benefits are a powerful draw.

When talking about the vs. I often mention that the pinebook is immune to and attacks. It is also a lot slower. Same holds true for vs. , apparently.

Nice thing about a licensed core is you could disable the (mis)feature!
