The AMD Opteron introduced x64. While Intel was still full steam on the P4 architecture and tried to push Ithanium. Only some years later Intel licensed the x64 instruction set - of course on chip they then did their own implementation of the x64 instruction set. Ithanium failed, because first it was delayed several years, got very expensive and power hungry. For a while it had quite a good performance, but due to the price it gained only a little foothold in the very expensive workstation market. The final nail in the coffin was, that the Opteron really launched the x86 based server marked. With the Opteron companies would for the first time replace Sparc etc. in the middle range servers. And when Intel also offered x64 chips the risk server market started to fade. I am not buying cheap ass laptops. But a lot of Apple laptops are held back by having to include extra chips for supporting thunder bolt, while this feature is promised for one of the next Intel cpu generations as being included into the cpu. Had the plain MacBook Thunderbolt via USB-C it would be more useful

The "AMD 64" spec was openly published in 2000, Intel did not license anything. Intel was planning to license the AMD64 ISA directly from AMD for Yamhill however that did not happen and they've ended implementing the spec on their own with their own ISA. Intel's X86_64 ISA is actually quite different than AMD's implementation, and funny enough neither of those are actually 100% in line with the original spec. The spec was published because it was an extension of the X86 instruction set, not a replacement, the x86 instruction set is available to AMD through the cross license deal they have with Intel. >I am not buying cheap ass laptops.

Had the plain MacBook Thunderbolt via USB-C it would be more useful Thunderbolt will always require additional chips (just like displayport, usb, and any other port on your computer), this is how the spec works, it was never designed to be implemented on die on the CPU. USB-C has nothing to do with Thunderbolt and vise versa, there is a mechanical compatibility standard that allows you to use the same physical port for Thunderbolt and USB via the type C connector. This isn't any different than Thunderbolt using the Mini-Display port mechanical standard. Thunderbolt has multiple mechanical standards including over a dedicated TB electrical port, a fiber optic port, DP electrical port, and USB-C electrical port. Nothing Intel is doing is holding Apple back, the reason why Thunderbolt 3 isn't available on Apple laptops yet is because Apple is 2-3 generations behind, the mid 2015 Macbook pro is using a 4th gen haswell CPU.
