PCIe Version
?
PCI Express is a high-speed serial computer expansion bus standard used for connecting high-speed components, replacing older standards such as AGP, PCI, and PCI-X. It has gone through multiple revisions and improvements since its initial release. PCIe 1.0 was first introduced in 2002, and in order to meet the growing demand for higher bandwidth, subsequent versions have been released over time.

Instruction Set
?
The instruction set is a hard program stored inside the CPU that guides and optimizes CPU operations. With these instruction sets, the CPU can run more efficiently. There are many manufacturers that design CPUs, which results in different instruction sets, such as the 8086 instruction set for the Intel camp and the RISC instruction set for the ARM camp. x86, ARM v8, and MIPS are all codes for instruction sets. Instruction sets can be extended; for example, x86 added 64-bit support to create x86-64. Manufacturers developing CPUs that are compatible with a certain instruction set need authorization from the instruction set patent holder. A typical example is Intel authorizing AMD, enabling the latter to develop CPUs compatible with the x86 instruction set.
