Enter Itanium.

I mean, we know they are all saying "arm" and "amd" both as negotiating tactic as well as strategically diversifying microarchitectures. That said, I'm not sure it's like amd can deliver more instructions per second per dollar.

I wonder if it would make sense for some loads to prepare for Itanium usage, or even older Atom architectures? Does any one deploy Itanium in the cloud?




It's worth noting that only pre-2013 Itanium CPUs are not vulnerable to meltdown (The same as with Atom CPUs). Intel has also said that the Itanium chips released in 2017 would be the last Itanium chips they will develop, so I don't think there's any reason to bother switching to Itanium. I would wager it's guaranteed you'll be better-off with the latest AMD instead of a 2013 Itanium, and AMD supports x86-64 so it doesn't require making your full software stack support Itanium (Which it likely doesn't).


> and AMD supports x86-64

I am sure you didn’t mean it this way, but it struck me as funny saying AMD supports x86-64. Of course AMD supports x86-64, they invented it. That is why Microsoft and Linux refer to that architecture as AMD64.

Itanium is not binary compatible with x86. Might as well think about arm if it would require change in ci pipeline/the set up from app developers.


Doesn’t it have an x86 emulation mode? If not, Intel messed up there.


Sure, and it's really slow.



It feels like now would be a good time for the openpower folks to get a tad louder.


fwiw Kimsufi is offering N2800 Atom CPUs for cheap, which don't appear to be vulnerable...
