AMD Zen 2 Update: 7nm EPYC in Labs Now, Launching in 2019

The peeps building Mill CPU are claiming they can do 10x performance over traditional (x86). IIRC in an early talk they explained this is mostly by bringing the IPC on a level with high IPC microcontroller arches. They do VLIW which can do a lot of things more efficiently if your compiler can handle it (Rust should be able to pull a lot of performance out of VLIW IIRC)

VLIW plus a "sufficiently smart compiler"? Isn't that IA-64 in a nutshell?

Basically, though Mill also is belt-based (think stack with size-limit) not registers and compilers nowadays are a bit better at VLIW than when IA-64 was introduced. They also have a shitload of security addons that would mitigate most modern exploits and other nice-to-haves.

Nah, the Mill is sufficiently different than a standard VLIW. I'm still on the fence about it, but it's noticeably different from the Itanic.
