One Thunderbolt 4 port can connect up to two 4K 60hz DisplayPort or HDMI monitors through a compatible dock or an adapter. Thunderbolt designated monitors can be connected directly. Connect a high-speed external Thunderbolt™ SSD to expand the storage capacity of your system and achieve speeds on par with internal drives. In other words, both Thunderbolt 3 and 4 are the compact and versatile connectors that you can use to charge your laptop, transfer files at fast speeds, connect external monitors and other peripherals, including PCIe compatible graphics units (like the Razer Core, or the Aorus Gaming Box).
Thunderbolt interface is very popular these days. Some people may want to know the differences between Thunderbolt 2 vs 3. In this post, MiniTool Partition Wizard will show you their differences.
Quick Navigation :
Introduction to Thunderbolt
Thunderbolt interface is the brand name of an external interface developed by Intel in collaboration with Apple. This interface combines PCI Express data transmission technology with DisplayPort display technology, so that it can transmit data and video signals at the same time.
Thunderbolt has the following features:
- It uses PCIe bus. Therefore, its speed is very fast.
- It is compatible with a variety of transmission protocols on the market, including USB protocols, Display Port protocol, Power Delivery, HDMI, etc.
- It supports hot swapping and Daisy Chain Topology.
With these features, you can do the following things:
- Use it as a USB port to connect external drives.
- Use it as a DP port or HDMI port to connect one or more display devices at the same time. You can also use it to connect an external GPU.
- Use it to connect a Docking station device, expanding external ports. Also due to this point, some Ultrabooks may be equipped with only one external port — Thunderbolt.

Thunderbolt 2 vs 3
So far, Thunderbolt interface has developed 4 generations: Thunderbolt 1 (10Gbps), Thunderbolt 2 (20Gbps), Thunderbolt 3 (40Gbps), and latest Thunderbolt 4 (40Gbps). Thunderbolt interface is very fast and useful. But the Thunderbolt 1 and 2 interfaces are not so famous. Not until Thunderbolt 3, does the Thunderbolt interface become popular suddenly. Why?
Some people may want to know the differences between Thunderbolt 2 vs Thunderbolt 3. Then, please keep reading to get answers.
Thunderbolt Development: Why Is Thunderbolt 3 So Popular?
Back in 2011, Thunderbolt 1 was released. Its bandwidth is 10Gbps and it uses Mini DP port. In 2013, Thunderbolt 2 was released. Like Thunderbolt 1, it also uses Mini DP port, but its speed increases up to 20Gbps.
Both Thunderbolt 1 and Thunderbolt 2 are much faster than USB 3.0. However, at that time, only Macbooks and a few laptop models used Thunderbolt interface. The reason is that Intel will charge huge copyright fees if other computer manufacturers want to use this interface. In addition, Thunderbolt devices are also expensive.
Note: Although the Thunderbolt interface is an interface jointly developed by Apple and Intel, its copyright has always been owned by Intel. If Apple wants to use the Thunderbolt interface, it also has to pay a lot of licensing fees to Intel.
In 2015, Thunderbolt 3 was released. Its speed increases up to 40Gbps and it uses USB Type-C port. Then, in 2017, Intel announced the cancellation of the licensing fee for the Thunderbolt 3 interface and decided to integrate the function into the processor chip.
Due to the above reasons, equipment manufacturers can save a large amount of money and therefore many computer manufacturers, such as Lenovo, HP, Dell, etc., started to produce computers with equipped with Thunderbolt 3 interface. From then on, Thunderbolt becomes more and more popular.
This post explains the differences between Mini DisplayPort and Thunderbolt to you.
Thunderbolt 2 vs 3: Details
In this part, I will show you the detailed differences between Thunderbolt 2 vs Thunderbolt 3.
1. Speed
Thunderbolt 2 uses PCI-E 2.0 X4 bus and Thunderbolt 2 speed is 20Gbps, while Thunderbolt 3 uses PCI-E 3.0 X4 bus and Thunderbolt 3 speed is 40Gbps.
However, if a computer is equipped with Thunderbolt 3 interface, it has the following choices (models):
- Double Port (DP): It uses a PCIe 3.0 ×4 link to provide two Thunderbolt 3 ports.
- Single Port (SP): It uses a PCIe 3.0 ×4 link to provide one Thunderbolt 3 port.
- Low Power (LP): It uses a PCIe 3.0 ×2 link to provide one Thunderbolt 3 port.
2. Port Shape
Thunderbolt 2 uses Mini DP port while Thunderbolt 3 uses USB Type-C port.
3. Display
Thunderbolt 2 incorporates DisplayPort 1.2 support, which allows for video streaming to a single 4K video monitor or dual QHD monitors.
Thunderbolt 3 incorporates 8-lane DisplayPort 1.2 support (in 2018, Intel upgraded it to DisplayPort 1.4), which can simultaneously drive two external 4K displays at 60 Hz, or a single external 4K display at 120 Hz, or a 5K display at 60 Hz when using Apple's implementation for the late-2016 MacBook Pros.
4. Power Consumption
Comparing to Thunderbolt 2, Thunderbolt 3 saves half of the electricity, and offers power supply to external devices up to 100W. This eliminates the need for a separate power supply from some devices.
5. Compatibility
Thunderbolt 2 is compatible with Thunderbolt 1 devices, DisplayPort devices (need an adapter). Thunderbolt 3 is compatible with Thunderbolt 1 and 2 devices (need an adapter), DisplayPort devices (need an adapter), and USB drives.
Tip: So many devices need adapters to connect to Thunderbolt interface, so a Thunderbolt docking station device is very useful.

Yes. You can connect Thunderbolt 3 devices to a Thunderbolt 2 port or connect Thunderbolt 2 devices to a Thunderbolt 3 port, but you need to use a Thunderbolt 2 to Thunderbolt 3 cable.
USB 3 speed is 5Gbps while Thunderbolt 2 speed is up to 20Gbps. Therefore, Thunderbolt 2 is faster than USB 3.
Is there a difference between Thunderbolt and Thunderbolt 2?
Does your first 'Thunderbolt' mean Thunderbolt 1? If so, there are differences between Thunderbolt and Thunderbolt 2 indeed. The key difference is that Thunderbolt 1 speed is 10Gbps while Thunderbolt 2 speed is 20 Gbps.
