Startup aims to make CPUs 100x more energy efficient with 'reconfigurable' chips

One cannot simply claim a 100x efficiency improvement without providing any numbers and expect people to just believe it.

The only thing pointing towards the efficiency improvement from what I can tell is the absence of backwards compatibility that modern processors have.

But doesn't ARM have that advantage too? Aarch64 isn't backwards compatible with Arm32 either.

I'd genuinely love to see a showcase regarding the efficiency improvements and at which power draw these processors operate.
