Thunderbolt 3 Vs Pci Express: Which Interface Reigns Supreme?
What To Know
- However, if you are on a budget or if you only need to connect a few internal devices, then PCI Express is a good option.
- PCI Express is a high-speed expansion bus standard for connecting peripheral devices to a computer, while Thunderbolt 3 is a high-speed interface developed by Intel in 2015.
When it comes to connecting peripherals to your computer, there are two main options: PCI Express (PCIe) and Thunderbolt 3. Both interfaces have their own advantages and disadvantages, so it’s important to understand the differences between them before making a decision. In this blog post, we’ll take a closer look at PCI Express vs Thunderbolt 3 and help you decide which one is right for you.
What is PCI Express?
PCI Express (PCIe) is a high-speed expansion bus standard for connecting peripheral devices to a computer. It was developed by Intel in 2003 and has since become the de facto standard for connecting graphics cards, sound cards, network cards, and other peripherals. PCIe is a serial interface, which means that data is transmitted over a single lane. This allows for very high data transfer rates, with the latest PCIe 4.0 standard supporting speeds of up to 16 GT/s (gigatransfers per second).
What is Thunderbolt 3?
Thunderbolt 3 is a high-speed interface developed by Intel in 2015. It is based on the USB-C connector and supports data transfer speeds of up to 40 Gbps. Thunderbolt 3 is also capable of carrying power, video, and audio signals, making it a versatile interface for connecting a wide variety of devices.
PCI Express vs Thunderbolt 3: Which is Faster?
When it comes to speed, Thunderbolt 3 has a clear advantage over PCI Express. Thunderbolt 3 supports data transfer speeds of up to 40 Gbps, while PCI Express 4.0 supports speeds of up to 16 GT/s. This means that Thunderbolt 3 is more than twice as fast as PCI Express.
PCI Express vs Thunderbolt 3: Which is More Versatile?
Thunderbolt 3 is also more versatile than PCI Express. It can be used to connect a wide variety of devices, including external storage devices, graphics cards, sound cards, network cards, and even monitors. PCI Express, on the other hand, is typically used for connecting internal devices such as graphics cards and sound cards.
PCI Express vs Thunderbolt 3: Which is More Expensive?
Thunderbolt 3 is typically more expensive than PCI Express. This is because Thunderbolt 3 requires a special controller chip, which adds to the cost of the device. PCI Express, on the other hand, does not require a special controller chip, so it is typically more affordable.
PCI Express vs Thunderbolt 3: Which is Right for You?
The best interface for you depends on your specific needs. If you need a high-speed interface for connecting a wide variety of devices, then Thunderbolt 3 is the best choice. However, if you are on a budget or if you only need to connect a few internal devices, then PCI Express is a good option.
The Verdict: PCI Express vs Thunderbolt 3
PCI Express and Thunderbolt 3 are both excellent interfaces with their own advantages and disadvantages. PCI Express is a more affordable and widely supported interface, while Thunderbolt 3 is faster and more versatile. Ultimately, the best interface for you depends on your specific needs.
Recommendations: Making the Right Choice
When choosing between PCI Express and Thunderbolt 3, it’s important to consider your specific needs. If you need a high-speed interface for connecting a wide variety of devices, then Thunderbolt 3 is the best choice. However, if you are on a budget or if you only need to connect a few internal devices, then PCI Express is a good option.
