AMD "Advanced Micro Devices has hired JPMorgan Chase & Co to explore options, which could include a potential sale, as the chipmaker struggles to find a role in an industry increasingly focused on mobile and away from traditional PCs, according to three sources familiar with the situation." Woah. Bad news for competition in the x86 space.

RE[3]: What about 64-bit only?

Data is 64 bit, instructions can use 16, 32 or 64 bits.
For example:

mov ah, bh //16 bit

mov ax, bx //32 bit

mov rax, rbx // 64 bit

Intel patents cover instruction set so you can't have x64 only cpus without infringing Intel's patents.

So that's why hardware patents are as bad as software patents because they hinder competition.
