Here is what it’s essential know concerning the completely different flavors of Thunderbolt

If you’re looking for a brand new PC or Mac and contemplating ports, it is normally most necessary to give attention to what number of USB-C connections there are, adopted by how briskly they run. Some pc makers nonetheless insist on loading machines with USB-A, regardless that USB-C is already de facto for a lot of telephones, tablets, SSDs, and different merchandise. Both approach, it is ridiculous that we’re nonetheless coping with 5Gbps ports in lots of circumstances when 10, 20, and 40Gbps variations of USB exist.

You’ve got in all probability seen one other connection sort floating about, although: Thunderbolt. Should you’re not acquainted, here is what it’s essential know concerning the completely different sorts of Thunderbolt, and why any new pc you purchase ought to have at the very least one port geared up for it.

Not all USB speeds are created equal (and yes, the numbers complicate things)

Confused by the assorted flavors of USB? So are we generally, however there’s arduous knowledge on the market.

Thunderbolt 1 and a pair of

The origins of the usual

Apple / Pocket-lint

I am lumping Thunderbolt 1 and a pair of collectively largely to say this — do not anticipate finding something new utilizing these applied sciences. Thunderbolt was born approach again in 2011 out of a collaboration between Apple and Intel, and certain sufficient, the primary two variations of the usual did not have a lot attain past the Apple ecosystem. Within the trendy tech panorama, one thing with both of them would possibly as effectively be an vintage.

At finest, you would possibly be capable of pair Thunderbolt 1 and a pair of peripherals with later variations of Thunderbolt by way of an adapter. However these peripherals are seemingly sufficiently old in their very own proper that you need to be monitoring down one thing newer, and even an adapter may not be sufficient. There have been basic architectural adjustments within the transition to Thunderbolt 3.

Thunderbolt 3

Outdated, however nonetheless usable

That is the oldest model of Thunderbolt you are more likely to encounter within the wild. That is as a result of it shares the identical connector sort as USB-C, and when you connect a USB cable, the usual helps speeds as much as USB 3.1 Gen 2 (10Gbps). Issues get way more spectacular with a real Thunderbolt pipeline, providing transfers of as much as 40Gbps. You additionally get DisplayPort 1.2 video output at a minimal, and 1.4 on more moderen iterations. Usually, there’s sufficient bandwidth to assist two 4K displays operating at 60Hz, or a single 4K display screen at 120Hz.

Energy supply varies. Optical Thunderbolt 3 cables cannot ship any energy, and copper ones are generally capped at 15W. After they assist USB-PD (USB Energy Supply), nevertheless, copper cables can deal with as much as 100W, which is sufficient to run some peripherals with out a separate energy wire.

That brings us to one of the crucial necessary options of Thunderbolt: daisy-chaining. It is generally potential to string a number of Thunderbolt peripherals collectively, decreasing the necessity for docks or further ports on the supply system. I say “generally” as a result of at the very least one peripheral has to have a number of Thunderbolt connections, and the apply would not appear all that widespread exterior of stringing a dock to a monitor.

Not all USB ports are made equal – here is why some are black, some are blue, and others are even teal coloured.

Thunderbolt 4

The most typical format

Razer

Thunderbolt 4 represents a significant leap ahead. Not by way of most bandwidth, thoughts — it is nonetheless capped at 40Gbps like Thunderbolt 3. Quite, it is as a result of Thunderbolt 4 is intimately tied to USB 4. Should you’ve bought a type of two, you’ve got virtually all the time bought the opposite, so it is now fairly widespread to seek out Thunderbolt on PCs, whereas you typically needed to exit of your approach to purchase a pc with earlier Thunderbolt variations until you have been a Mac fan.

The improve additionally contains assist for Thunderbolt Alternate Mode USB hubs, with that Alt Mode enabling two bidirectional 40Gbps channels per connection. Due to this and USB 4’s broader enchantment, there’s been an explosion in Thunderbolt docks, which let you dramatically develop your pc’s port capability and/or declutter your desktop. My Razer dock, for instance, contains 4 Thunderbolt 4/USB-C connections, three USB-A 3.2 Gen 2 ports, an SD/UHS card reader, and a gigabit Ethernet jack. If I wished to, I may fully skip the ports constructed into my laptop computer.

Some tablets assist Thunderbolt 4 as effectively, similar to Apple’s iPad Professional. Certainly, you will in all probability want a Thunderbolt dock when you intend to show a pill right into a workstation, since there’s typically only one or two wired connections out there.

Thunderbolt 5

The bleeding edge

Razer

Thunderbolt 5 is the latest iteration, and arguably a good additional leap forward than 3 or 4. On gadgets with USB 4 v2, the format helps two-way transfers as much as 80Gbps, and unidirectional ones as much as 120Gbps, with the second channel dropping to 40Gbps. That may make an enormous distinction in backing up drives or working with giant quantities of video content material. Even at 80Gbps, you are copying a 1TB folder in solely a minute and 40 seconds.

There’s extra. For each storage and exterior graphics {hardware}, there’s improved knowledge throughput utilizing PCIe Gen 4×4. You additionally get assist for DisplayPort 2.1 video output, and as much as 240W of downstream energy for hooked up gadgets. Relying on the precise cables and gadgets you’ve got bought, that DisplayPort compatibility can allow a really spectacular gaming rig — at peak efficiency, you will pump out 4K video at 240Hz, or 8K at 85Hz. Extra virtually, you possibly can arrange two 4K 120Hz displays or an equal ultrawide.

There are two large catches with Thunderbolt 5, the primary being the rarity of USB 4 v2 on computer systems. On high of that’s the value and availability of Thunderbolt 5 equipment — the format has solely been round since 2024, so there is a restricted vary of choices, and you will be paying extra for the privilege. I might follow Thunderbolt 4 for now when you’re not involved with maximizing show or storage speeds.
