Thunderbolt 5. The cutting fringe of I/O. All of it — monitors, a Thunderbolt 5 dock, and even a Thunderbolt 5 SSD — became perched on my desk. I became satisfied, in the formulation handiest tech nerds would possibly also be once they’ve a chunk of equipment few others discontinue.
Just a few days later, I became more than satisfied to purchase it aside and return to a slower and more functional Thunderbolt environment. Because I am merely not sure that the Thunderbolt 5 ecosystem is ready for prime time.
This isn’t an indictment of Thunderbolt 5, per se. Rather, it’s all about the complications that can accompany not one, however a mess of gadgets, all of which will trust interplay with every assorted in unexpected ways. Layer on software, drivers, firmware updates, and the esteem, and it’s grand to level an accusing finger at somebody component. Here’s what testing cutting-edge hardware can mean: combating know-how that must factual work, however doesn’t.

Thunderbolt 5: The following generation of I/O
Thunderbolt 5 became announced about a year ago, as the following step in the evolution of the Thunderbolt I/O authorized. Thunderbolt wasn’t basically designed for vitality users, however the most attention-grabbing Thunderbolt 3 and Thunderbolt 4 docks enables users to residing a pair of 4K displays on their desk working at 60 Hz. I salvage this extremely worthwhile for productiveness, as I’m able to location up loads of dwelling windows’ price of email, chat, calendar, Net browsers, and more on two or more displays.
Each Thunderbolt 3 and 4 provide 40Gbps of throughput. Thunderbolt 5 will enhance that to 80Gbps, and in definite instances as much as 120Gbps, too. This extra bandwidth plays right into the gaming and productiveness rental, as the extra bandwidth helps as much as 3 4K displays at 144Hz, two 8K displays at 60Hz, or a single 1080p bid at 540Hz. (Intel hasn’t nailed down the specifics of these final two resolutions). Intel is also touting the truth that Thunderbolt 5 must be ready to vitality external GPUs, a functionality that became handed over in Thunderbolt 4.
The divulge is that Thunderbolt 5 hardware is in short provide, period. Even when about a of the earliest Thunderbolt 5 docks trust been shown off this previous January, it’s now October, and about the perfect dock I’ve considered announced is Kensington’s SD5000T5 EQ, which I went hands-on with about a minutes ago. There aren’t too many Thunderbolt 5 cables, either.
However a hands-on will not be a take a look at and I became desirous to secure hardware that I’d also use to place the Kensington SD5000T5 by its paces: to join it to 3 4K144 displays by a notebook computer with Thunderbolt 5 connections and, as a bonus, to worth if I’d also salvage an SSD that would also speed at Thunderbolt 5 speeds.
I wasn’t expecting it to be easy. For despite motive, gadgets with Intel’s Thunderbolt 5 host and accent component (“Barlow Ridge,” or the Intel JHL9580 and JHL9480) trust been few and some distance between. Docks are aloof scarce, as I acknowledged, and handiest two notebooks to my recordsdata ship with a (non-integrated) Thunderbolt 5 controller, a version of the Razer Blade and the Maingear ML-17.

Luck preferred me. The Kensington SD5000T5 remained on my desk, and Maingear agreed to send over an ML-17 for evaluate. A colleague also became in the formulation of reviewing a pre-open version of OWC’s Envoy Ultra Thunderbolt 5 SSD and agreed to let me take a look at it for about a minutes in commerce for some benchmarking outcomes. Every thing looked as if it may per chance possibly most likely be coming together.
Thunderbolt 5 started off poorly, then bought worse
Just a few days later, I had cleared the decks of all of my recent projects, and sat correct down to play with the following generation of I/O vitality. I updated the ML-17 with the predominant Home windows updates, Microsoft Store updates, on hand firmware updates, and heaps others. Maingear shipped the notebook to me with the Intel Driver & Enhance Assistant utility updated as effectively, so I became pretty sure that I had basically the most recent hardware and drivers.
The first steps trust been rather obvious. As most gamers know, gaming notebooks consist of a hefty vitality brick terminating in either a barrel charger or the squarish vitality connector. One among the benefits of Thunderbolt 5, however, is its ability to produce a hypothetical vitality map of 240W. Supreme being ready to plug in the gaming notebook into the Thunderbolt 5 dock and vitality it up without the need for the notebook computer’s ungainly external vitality connector left me rather satisfied.
Properly, more or less. I later found that the dock would vitality the notebook computer on factual one in all the two Thunderbolt 5 ports, however, and checking it with a USB vitality meter found that it delivered no more than 87W, even while gaming.
Label Hachman / IDG
Energy provide of 240W requires explicit toughen from the notebook computer, dock, and cable and I wasn’t too tremendously a good deal surprised that it didn’t meet my expectations. Unfortunately, however, the pattern persevered.
Acer graciously supplied three of its Nitro XV5 (XV275K) 4K displays for a take a look at bed. All three displays speed as much as 144Hz on the HDMI port and to 160Hz on the USB-C/DisplayPort, which must aloof trust been right sufficient to satisfy the Thunderbolt 5’s promised to render a image at 144Hz on three 4K displays.
Unfortunately, that didn’t occur. Maingear’s notebook computer produced a image on factual two of the displays plus the notebook computer itself. (Thunderbolt 4 docks output to 2 4K displays, plus the notebook computer, so I design not trust any motive to mediate my interpretation of “three displays” became inaccurate.). While one notebook computer rendered at 4K 144Hz factual neutral, it became a right strive in opposition to to build up the assorted to discontinue the the same at 1440p — it took some unplugging and re-plugging to enact it factual once, slowly. I’d also not continuously repeat this.
(Kensington’s dock offers three upstream Thunderbolt 5 ports. I susceptible Kensington’s private USB-C to HDMI adapter to join to one bid, plus two uni 4K60 USB-C to DisplayPort cables — that are handiest rated for 1440p165, not 4K — for the others. I hoped that three displays would illuminate. They didn’t).

If truth be told, your whole setup felt pretty laggy factual navigating across the notebook computer and by a Net browser — not one thing you’d achieve a matter to with a prime-of-the-line Intel CPU and Nvidia GeForce RTX 4090 GPU internal. I’m pretty sure the Thunderbolt connection negatively contributed. Streaming a 4K, 60Hz video stuttered badly when speed on the external bid that became linked to the Thunderbolt dock — effectively over 30 p.c of the frames trust been lost. Taking half in support the the same video on factual the notebook computer itself wasn’t wonderful, however it became great, critically better.
Maingear blamed this on the Thunderbolt 5 cable. “I haven’t examined a plethora of cables yet, however the Apple TB5 Legitimate cable has labored continuously for us,” a Maingear representative wrote in an email. “The place Thunderbolt 4 you trust been ready to build up away with a tight USB-C cable, Thunderbolt 5 appears to be like to work most attention-grabbing with certified Thunderbolt 5 cables.”
That can be factual, however Kensington’s Thunderbolt 5 cable became labeled as it must be and this must be certified. And why must aloof I trust to hold an Apple cable to build up my PC docking place to work?

Storage performance suffered as effectively
As soon as I linked the SSD, the performance of my Thunderbolt 5 take a look at setup became factual as sinful. I on the general speed PCMark’s external storage benchmark to envision a dock. My colleague Jon Jacobi prefers working storage-explicit benchmarks to envision the performance of the SSD at once. I score PCMark, whose external storage take a look at reports the “bandwidth” of the SSD. That’s what I’m aiming for: How great recordsdata does the drive trust to work with?
I also take a look at a 2d formulation, by recording the time it takes to duplicate a folder fleshy of multimedia and various recordsdata from the SSD, by the dock, onto the notebook computer. I discontinue all that by itself and also while streaming a 4K 60Hz video by the Data superhighway over the Thunderbolt cable, factual to worth whether or not a background file switch will impact performance.
The abilities, rather frankly, stunk. While working the PCMark take a look at with the SSD at once linked, I recorded a ranking of 1,743 or 252.3 MB/s. However while linked to the dock, the SSD’s PCMark ranking plunged to factual 1,108 or 159.3MB/s. Became once that the dock’s fault or the Thunderbolt 5 connection? One among the two, most likely.
As soon as I at once linked the SSD to the notebook computer and copied my folder to the desktop, it took an average of one minute and 5 seconds. While streaming video, the the same process took 58 seconds longer or two minutes and three seconds. That looked rather coarse.
Weirdly, when I linked the SSD to the dock and then performed the folder duplicate, it carried out in 41 seconds — some distance faster! However performing the folder duplicate while streaming the video required two minutes and six seconds, again with the SSD attached to the dock. (The Data superhighway connection became supplied by Ethernet, which remained linked. However letting the draw use Wi-Fi didn’t seem to trust any disagreement).
It’s price a reminder that when I examined the Kensington dock on a “authorized” Thunderbolt 4-equipped notebook computer and a slower SSD, the dock performed “in most cases,” as effectively.
In the previous few years, we’ve considered the occasional odd result when benchmarking, comparable to benchmarks of cell CPUs speed on battery vitality that exceed the performance of the the same notebook computer while plugged in. Peaceable, the wildly varying outcomes, including the heavy stuttering while playing video, suggested me one thing’s not rather right. What is it? I don’t know, which is souring me to your whole Thunderbolt 5 abilities.
Should always aloof you hold Thunderbolt 5? Now not straight away
When testing a single draw, a right evaluate works to isolate the variable. Desktop CPUs are examined in opposition to the fastest GPUs which that you just can private of, with neatly-liked motherboards, memory, and storage (if which that you just can private of), in divulge that any variations in performance would possibly also be at once attributed to the new CPU.
Label Hachman / IDG
In this case, I’m testing a brand new dock, notebook computer, and SSD, with new cables working between them. That’s at the very least three unknowns I’m able to’t with out a doubt nail down. So Maingear can accuse the cable of being terrible, while I believe that Maingear’s hardware would possibly also honest be at fault. I’m able to’t know for definite.
What I am quite suspicious about is the relative lack of Thunderbolt 5 hardware, even slack in 2024. Intel has cycled by its Lunar Lake and Arrow Lake launches, and neither entails an integrated Thunderbolt 5 controller. Intel gave some right reasons for aside from it — desktop distributors score to “upsell” by the usage of discrete substances, for instance — however the instability that I’m seeing makes me shock if there’s one thing more occurring.
I’m not writing Thunderbolt 5 off in any appreciate. An updated driver would possibly also potentially resolve this divulge or it may per chance possibly most likely also require a more sophisticated hardware revision to Intel’s Barlow Ridge controller itself. I don’t know.
For now, however I’d not indicate trying to salvage into the Thunderbolt 5 ecosystem. Should always you hold (or take a look at) bleeding-edge hardware, infrequently you’re the one who ends up with the cuts.
