If you’re referring to the 13&14th Gen chips then yes, Intel is saying it’s on the software side.
But if you’re talking about 10th Gen chips that took forever to get out of the gate due to issues with sub 14nm lithography, then no it’s a hardware issue. Intel has had issues over recent years with actual die shrinks.
Yeah nice fast and break things is a great way to maximize short term profits at the expense of the long term. But fuck it, I got mine in the short term, so it works.
