When it comes to building or upgrading a computer, choosing the right video card is crucial for optimal performance. One of the most important factors in selecting a video card is understanding what slots it uses. In this tutorial, we will dive into the various types of slots that video cards use.
First and foremost, we have the PCI (Peripheral Component Interconnect) slot. This is an older type of slot that has been around since the early 1990s.

Although most modern video cards no longer use this slot, it is still worth mentioning as some older machines may still have a PCI slot available. The PCI slot has a maximum bandwidth of 133 MB/s, which may not be enough to handle high-end graphics.
Moving on to more modern options, we have the AGP (Accelerated Graphics Port) slot. This type of slot was prevalent in computers from the late 1990s through the mid-2000s.
AGP slots are typically brown in color and are positioned farther away from other expansion slots on the motherboard. They can provide up to 2 GB/s of bandwidth, making them suitable for mid-range gaming and graphics applications.
Next up is the PCIe (Peripheral Component Interconnect Express) slot. PCIe is currently the most common type of slot used for video cards and other expansion cards.
There are several different versions of PCIe, with each version providing different amounts of bandwidth. PCIe version 1.x provides up to 250 MB/s per lane, while version 2.x provides up to 500 MB/s per lane. The latest version, PCIe 4.x, can provide up to 2 GB/s per lane.
There are also different physical sizes for PCIe slots, including x1, x4, x8, and x16. The size refers to how many lanes are available for data transfer between the video card and motherboard. A larger size usually means more bandwidth and better performance overall.
It is also worth noting that some video cards may require additional power from the power supply unit (PSU) in your computer. This can be done through a PCIe power connector, which is typically a 6-pin or 8-pin connector that plugs directly into the video card.
In conclusion, understanding what slots video cards use is crucial for building or upgrading a computer. While older machines may still have PCI or AGP slots available, most modern video cards use PCIe slots.
It’s important to consider both the version and size of the PCIe slot when selecting a video card, as well as any additional power requirements. By doing so, you can ensure optimal performance and an enjoyable gaming or graphics experience.
