O que significa a inscrição "Costa Rica" em um processador Intel?
Is this some codename for a certain CPU-modification or just a place where this model was developed/produced?
As marcações na parte de trás da CPU referem-se ao local de embalagem, não ao local de fabricação do chip de silício real
Marcas de CPU da Intel (ou seja, Malay vs. Costa Rica)
Just to clear something up, the markings on the back of the CPU refer to the packaging site - not the manufacturing site of the actual silicon chip itself.
Intel has no fabs in either Malaysia or Costa Rica, they are packaging facilities. The silicon die/chips are manufactured elsewhere in the world and are shipped to either of these two packaging sites.
In addition, Intel manufacturing has a goal of running a "virtual fab" - meaning that, among other things, products from one fab are statistically indistinguishable from those manufactured at another fab.
So even if, for example using fake names, Malaysian packages used chips only from fab #1 and packages marked Costa Rica use chips from fab #2, there should be no difference statistically between these two.
