Thunderbolt 3 is a revolutionary technology that has transformed the way we connect devices and transfer data. With its incredible speeds and versatility, it’s no wonder that Thunderbolt 3 has become the go-to choice for many professionals and enthusiasts. But have you ever wondered what makes Thunderbolt 3 tick? In this article, we’ll delve into the world of Thunderbolt 3 and explore one of the most common questions: does Thunderbolt 3 use PCIe?
What is Thunderbolt 3?
Before we dive into the nitty-gritty of Thunderbolt 3’s architecture, let’s take a step back and understand what Thunderbolt 3 is. Thunderbolt 3 is a hardware interface developed by Intel that allows for the connection of external devices to a computer. It’s a multi-purpose port that can be used for data transfer, display output, and even power delivery. Thunderbolt 3 is capable of speeds of up to 40 Gbps, making it one of the fastest interfaces available.
Thunderbolt 3 vs. USB-C
One of the most common misconceptions about Thunderbolt 3 is that it’s the same as USB-C. While it’s true that Thunderbolt 3 uses the same physical connector as USB-C, they are not the same thing. USB-C is a type of connector that can be used for a variety of purposes, including data transfer and power delivery. Thunderbolt 3, on the other hand, is a specific protocol that uses the USB-C connector to deliver high-speed data transfer and other features.
What is PCIe?
Now that we’ve covered the basics of Thunderbolt 3, let’s talk about PCIe. PCIe, or Peripheral Component Interconnect Express, is a type of interface that allows devices to communicate with each other. It’s commonly used in computers to connect peripherals such as graphics cards, sound cards, and storage devices. PCIe is known for its high speeds and low latency, making it a popular choice for applications that require high-performance data transfer.
How Does PCIe Work?
PCIe works by using a point-to-point architecture, where each device is connected directly to the CPU or chipset. This allows for high-speed data transfer and low latency, as data doesn’t have to travel through a shared bus. PCIe also uses a serial interface, which means that data is transmitted one bit at a time. This allows for faster data transfer rates and lower power consumption.
Does Thunderbolt 3 Use PCIe?
Now that we’ve covered the basics of Thunderbolt 3 and PCIe, let’s answer the question: does Thunderbolt 3 use PCIe? The answer is yes, Thunderbolt 3 does use PCIe. In fact, Thunderbolt 3 is built on top of the PCIe protocol, using the same underlying architecture to deliver high-speed data transfer.
How Does Thunderbolt 3 Use PCIe?
Thunderbolt 3 uses PCIe in a few different ways. First, Thunderbolt 3 uses the PCIe protocol to deliver data transfer speeds of up to 40 Gbps. This is made possible by the use of four PCIe lanes, which are combined to deliver the high-speed data transfer. Thunderbolt 3 also uses PCIe to deliver display output, allowing users to connect external displays to their computer.
Thunderbolt 3 and PCIe Lanes
One of the key features of Thunderbolt 3 is its use of PCIe lanes. A PCIe lane is a single channel of data transfer, and Thunderbolt 3 uses four of these lanes to deliver its high-speed data transfer. This allows for a total bandwidth of 40 Gbps, making Thunderbolt 3 one of the fastest interfaces available.
| Interface | Number of PCIe Lanes | Bandwidth |
|---|---|---|
| Thunderbolt 3 | 4 | 40 Gbps |
| USB 3.2 Gen 2 | 1 | 20 Gbps |
Benefits of Thunderbolt 3 Using PCIe
So why does it matter that Thunderbolt 3 uses PCIe? There are several benefits to using PCIe, including:
- High-speed data transfer: PCIe allows for high-speed data transfer, making it ideal for applications such as video editing and 3D modeling.
- Low latency: PCIe’s point-to-point architecture and serial interface make it ideal for applications that require low latency.
- Compatibility: PCIe is a widely-used interface, making it easy to find compatible devices and peripherals.
Real-World Applications of Thunderbolt 3 and PCIe
So what are some real-world applications of Thunderbolt 3 and PCIe? Here are a few examples:
- Video editing: Thunderbolt 3’s high-speed data transfer and low latency make it ideal for video editing applications.
- 3D modeling: Thunderbolt 3’s high-speed data transfer and low latency make it ideal for 3D modeling applications.
