That may change over time, but the complexity of x86 as an architecture will be difficult to overcome. For x86, the instruction set itself is costly in a power sense, as the fetch, decode ...

Some would say that all x86 instructions are crazy, especially if you are accustomed to reduced instruction set computers. The x86, like other non-RISC processors, has everything but the kitchen sink.

Intel and AMD said several tech giants are backing their new effort to expand the ecosystem for the x86 instruction set architecture at the heart of their dueling CPU businesses. The Santa Clara ...

Also making the list are Intel and AMD who, despite their long-running rivalry, this week launched an initiative together to expand the ecosystem for the x86 instruction set architecture.

to hold an x86 instruction set architecture license. Intel initially developed x86 in the 1970s and emerged as the instruction set required for IBM PCs and, later, Microsoft’s operating systems.
