Advancements like PCIe 5.0 and beyond, which promise even greater performance enhancements for future hardware upgrades, are already the result of the growing demand for higher bandwidth and faster data transfeavatorr rates. More advanced applications in fields like virtual reality, high-performance computing, and artificial intelligence—which call for powerful processing power and quick data handling—will probably be made possible by these developments. Also, the function of conventional expansion slots may alter dramatically as we move toward more integrated systems with smaller form factors, like laptops and compact desktops.
