Understanding Thunderbolt 3: The Foundation
What Makes Thunderbolt 3 Special?
Thunderbolt 3 had a dramatic effect on the connection technology when it was launched in 2015. The new standard made the USB-C form factor that is most familiar to users the most recognizable way. In other words, the Thunderbolt cable design was more common and easier for the user to handle.
The most important specifications of Thunderbolt 3 are
- Data transfer rate of up to 40 Gbps
- At least one 4K display is supported
- PCIe bandwidth of no less than 16 Gbps
- Power delivery up to 100W
- USB-C connector compatibility
Thunderbolt 3 vs 4 Data Transfer Speed Basics
Both standards allow the same maximum speeds of 40 Gbps. But their minimum requirements are substantially different. Thunderbolt 3 cables are capable of reduced speeds of 20 Gbps for longer cables. This inconsistency caused both user confusion and ‘performance issues’.
Pro users frequently faced the problem of cable performance that was not consistent. Some Thunderbolt 3 cables were efficient enough to support full speeds, while others lacked that capability. This variability made it hard to plan the system for use in challenging applications.
Thunderbolt 4: Enhanced Specifications and Reliability
Key Improvements in Thunderbolt 4
Thunderbolt 4 brought more clear-cut certification requirements made by Intel, and hence less ambiguity from the side of Thunderbolt 3. Every Thunderbolt 4 cable should be able to deliver the same level of performance.
Main Thunderbolt 4 upgrades include:
- Mandatory 32Gbps PCIe data speed
- Support for one 8K display or two 4K displays
- Performance by universal cable up to 2 meters long
- Laptop charging capability is mandatory
- Strengthened security features
- Up to 4 Thunderbolt 4 ports in docking stations
Security Benefits of Thunderbolt 4
Security was a large step up for Thunderbolt 4. Intel VT-d-based DMA protection is required to thwart rogue devices from accessing memory over the Thunderbolt port.
Thunderbolt 3 only had these security features optionally. The cost meant many manufacturers did not implement them. Thunderbolt 4 security is mandatory, thereby preventing user harm.
Thunderbolt 3 Versus 4 Specs: A Detailed Comparison
Performance Requirements
Both Thunderbolt 3 and 4 specs offer maximum speeds of 40Gbps. In contrast, Thunderbolt 4 requires that 32 Gbps for PCIe data be present in order to qualify as a standard, versus Thunderbolt 3, which only needs 16Gbps.
Thunderbolt 4 brings quite a bit of improvement in video support. With the new standard, you can drive two 4K displays or a single 8K display minimum. Up to a 4K display was the best that Thunderbolt 3 could guarantee.
Cable performance differed between the two standards. With Thunderbolt 3, cables varied in length and quality. All Thunderbolt 4 cables guarantee consistent 40Gbps performance up to 2m.
Thunderbolt 4 requires that devices powered by batteries be able to charge, while this was optional in Thunderbolt 3. In Thunderbolt 4, security measures are still compulsory. In Thunderbolt 3, they were optional.
Display Performance: Thunderbolt 4 vs Thunderbolt 3
In terms of display support, Thunderbolt 4 is much better than Thunderbolt 3. Thunderbolt 3 could only guarantee one 4K display. A lot of implementations support even more, but it is not demanded.
Thunderbolt 4 requires support for two 4K displays at 60Hz. Here, one can also connect a single 8K display at 30Hz. This standard makes it easy for professionals planning their multi-monitor setups to know what they need to do.
Improvements to Docking Stations
With a Thunderbolt 4 dock, compatibility and functionality are greatly improved compared to previous Thunderbolt 3 docks. Most Thunderbolt 3 docks only offered two ‘downstream ports’. With a Thunderbolt 4 dock, you can have as many as four Thunderbolt 4 ports.
This expansion allows for a more complex setup. So users may plug in multiple high-speed devices simultaneously without a loss in their performance level. Because the better bandwidth will be distributed across connected devices more evenly, all of them will now have ‘uniform speed’.
Will Thunderbolt 3 cables work with Thunderbolt 4 ports? Backward Compatibility Explained
Many people want to know if you can connect Thunderbolt 3 and 4? The answer is yes. Thunderbolt 3 devices and cables can be used with Thunderbolt 4 ports. Unfortunately, performance will be limited to ‘Thunderbolt 3 speeds’.
So then the answer to “Can I use a Thunderbolt 3 cable instead of 4?” is also affirmative. Today’s Thunderbolt 4 cables work normally with Thunderbolt 3 ports, and depending on the type of cable you use, your port will provide the best ‘performance again’.
Cable Performance Considerations
Thunderbolt 4 is good for carrying a 40 Gbps signal for longer distances. All Thunderbolt 4 cables meet identical standards, making them free of that particularly galling aspect Thunderbolt 3 users should remember so well.
When choosing cables, think hard about your real requirements. With either standard, short connections beneath 0.5 meters perform admirably. Longer connections receive a big boost from Thunderbolt 4 cables.
Thunderbolt vs. USB-C: Understanding the Relationship
The Relationship Between Thunderbolt and USB-C
Many users get lost over the relation of Thunderbolt 4 to USB-C. Though the connector for Thunderbolt 4 is USB-C, it has completely superior performance. Not every USB-C port supports ‘Thunderbolt technology’.
