Isn't adding pins kind of expensive?
- arnitdo 3mo agoWell to be honest, there are a lot of NOOP pins on CPUs, but using them basically means fabbing a new die altogether, which is basically making a whole new CPU altogether.
- bronson 3mo agoThis is an odd comment. Pins are seriously expensive. Companies don't just throw them in for fun. Usually they're necessary for signal integrity or packaging constraints.
- codedokode 3mo agoYes but not $1000 level expensive, right? It is just a tiny piece of metal, and on laptops there are no pins at all.
- numpad0 3mo agoI think this is about semiconductor design and/or die packaging related difficulties/costs. idk exactly why, but "pin count" in this exact expression is not rare at all on chip marketing materials.
