The 8086 instruction set is not the only instruction set that modern x86 supports. There are dozens of instruction sets from the well-known floating-point, SSE, ...

However, the advent of the 64-bit era didn’t signify the end of progress for x86. The first milestone here was the introduction of the baseline AMD64 x86-64 instruction set with MMX, SSE, and SSE2.

The x86 instruction set was first introduced by Intel in 1978 with the 8086 16-bit CPU, and the Santa Clara corporation is now planning to finally bring its computer processors into the future ...

It expands the entire x86 instruction set, granting access to more registers and introducing new features to enhance overall CPU performance. APX, according to Intel, ...

Intel and AMD took over the server processor market in the mid-2000s. This happened after AMD introduced 64-bit instructions into the x86 instruction set with its Opteron processor architecture.

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.

Arm is RISC (Reduced Instruction Set Computing) based, while x86 is CISC (Complex Instruction Set Computing). Arm’s CPU instructions are reasonably atomic, with a very close correlation between ...

With its more complex instructions, too, x86 can have a more complex pipeline. For example, x86 uses a variable-length instruction set from 1 to 15 bytes, whereas Arm itself is of a fixed length ...

Hello all, I have a question regarding CPU instruction sets. I have heard that the aging x86 instruction set is holding back progress, so to speak. So I ...
