None of them do any fabrication which is what’s Moore’s Law applies to.
> In fact, he even said Intel could surpass the pace of Moore's Law at least until 2031 and has promoted "Super Moore's Law," a strategy to boost transistor count using 2.5D and 3D chip packaging technologies such as Foveros. Intel also often refers to this strategy as "Moore's Law 2.0,"
Regardless of transistors getting smaller, companies are outpacing Moore's law by making the CPU physically larger. They design the CPU so that it's composed of multiple chiplets. Since now there can be 7 chiplets that are closely connected, the # of transistors in one CPU is increasing faster than Moore's law. With the announcements about stacking CPU dies on top of each other in 3D, there will be even more chiplets in one CPU in the future.
Nvidia, Apple and AMD do not do that (at scale)

Intel is x10 the size of AMD.
They are also the only ones to have their own chip production capability. AMD and Nvidia are a Tawain Straits conflict liability.
