When did PCI-e 4.0 Come Out?

The progression in computing technologies often comes in leaps and bounds. One such pivotal leap was the introduction of the PCIe 4.0 standard. For tech enthusiasts and professionals, the release of a new standard like this isn’t just a minor update—it’s a game-changer. But when did this transformative technology make its debut? Let’s explore.

The Genesis of PCIe 4.0

PCI Express (PCIe) has been a staple in the computing world since its inception, with each version pushing the boundaries. PCIe 4.0, doubling the bandwidth of its predecessor, PCIe 3.0, was officially introduced by PCI-SIG (PCI Special Interest Group) in 2017.

Why PCIe 4.0 Was a Big Deal

  • Doubled Bandwidth: PCIe 4.0 offered a whopping 16 GT/s (gigatransfers per second), a significant jump from the 8 GT/s of PCIe 3.0.
  • Future-Proofing: With the explosion of data-intensive tasks and applications, this standard was a forward-looking solution for emerging tech challenges.
  • Compatibility: Despite its advancements, PCIe 4.0 maintained backward compatibility with previous PCIe generations.

First Implementations and Market Reception

  1. AMD Takes the Lead: AMD was among the first to adopt PCIe 4.0, integrating it into their Ryzen 3000 series CPUs and X570 motherboards in mid-2019.
  2. Data Centers and Workstations: The boosted bandwidth was a boon for data-intensive tasks, making PCIe 4.0 a favorite in professional setups.
  3. Initial Market Hesitation: As with most tech advancements, some industry players adopted a wait-and-watch approach, gradually warming up to the new standard.

The Future: Beyond PCIe 4.0

While PCIe 4.0 was groundbreaking, the tech world never remains static. The development of PCIe 5.0 and even PCIe 6.0 promises even more significant advancements in data transfer speeds and efficiency.

Frequently Asked Questions

How does PCIe 4.0 impact gaming? While the bandwidth is crucial for tasks like data rendering, the immediate impact on gaming might not be as noticeable. However, with games becoming more data-intensive, the relevance of PCIe 4.0 will undoubtedly increase.

Is it worth upgrading to PCIe 4.0 now? It depends on your needs. If you’re involved in data-heavy tasks or professional applications, an upgrade can be beneficial. For average users, the noticeable differences might be minimal.

When will PCIe 5.0 become mainstream? PCIe 5.0, already introduced by PCI-SIG, is gradually making its way into the market. Major tech players are beginning to integrate it, so its widespread adoption might be sooner than we think.


The release of PCIe 4.0 was not just a step but a giant leap in the computing landscape. As we reminisce about its introduction and the ripples it caused, it’s also essential to look forward to what the future holds. In the ever-evolving tech realm, today’s marvel is tomorrow’s norm.
