Almost all modern motherboards currently have a PCI-E x16 expansion slot. This is not surprising: a discrete graphic accelerator is installed in it, without which the creation of a productive personal computer is generally impossible. It is about his background of appearance, technical specifications and possible modes of operation that will be discussed later.

Be that as it may, the PCI-E x16 is currently a non-alternative graphics slot and interface. It will be relevant for quite some time. Its parameters allow you to create both entry-level computer systems and high-performance PCs with several accelerators. It is due to such flexibility that no significant changes are expected in this niche.
