Comparison
USB-C is the oval connector on most modern laptops. Thunderbolt 5 is a certified standard that uses that connector and guarantees 80Gbps data (up to 120Gbps for displays), 140W+ charging, and multi-monitor support. Every Thunderbolt 5 port is USB-C, but most USB-C ports aren’t. You only need it for fast external SSDs, multiple high-refresh monitors, or an eGPU.
- USB-C is a reversible 24-pin connector the USB-IF first specified in August 2014. It defines the plug, not the port’s speed, charging, or video support.
- Behind the same plug, a laptop port can run anything from USB 2.0 at 480Mbps to USB4 Version 2.0 at 80Gbps, depending on the controller chip.
- Intel’s Thunderbolt 5 (announced September 2023) requires 80Gbps in both directions, a 120Gbps Bandwidth Boost mode, 64Gbps PCIe Gen 4 x4, DisplayPort 2.1, and at least 140W of laptop charging.
- In 2026, Thunderbolt 5 ships on the MacBook Pro with M5 Pro or M5 Max and on Windows workstations and gaming laptops such as the ThinkPad P1 Gen 8 and Razer Blade 16. Every model in our price table starts above $2,000.
- A full Thunderbolt 5 setup (laptop premium, dock, and certified cable) costs roughly $500 to $1,070 more than a comparable Thunderbolt 4 laptop paired with the dock and cables you already own.
You plug a new dock into your laptop’s USB-C port. The charging light comes on. Your second monitor stays black.
Nothing is broken. The port just isn’t the kind you assumed it was.
That’s the frustrating part of the USB-C vs Thunderbolt 5 question. A budget laptop and a $3,500 workstation can have ports that look exactly alike, yet one might top out at 10Gbps while the other moves data at 80Gbps. The difference isn’t the plug. It’s the standard running behind it.
In 2026, you’re more likely to run into that gap. Thunderbolt 5 has moved beyond early-adopter gear and into premium MacBook Pro models and a growing list of high-end Windows laptops. This guide explains what it adds, how to spot it, and whether it’s worth paying for.
USB-C (USB 3.2 / USB4)
Anywhere from 480Mbps to 80Gbps, depending on the chip. Charging and video output are optional. Found on nearly every laptop.
Thunderbolt 5
80Gbps guaranteed (120Gbps Bandwidth Boost), 140W+ charging, and up to three 4K 144Hz monitors. Mostly found on laptops over $2,000.
Choose a regular USB-C, Thunderbolt 4, or USB4 laptop if you use one or two monitors, a standard dock, and everyday drives, or you’re shopping under $2,000.
Choose Thunderbolt 5 if you edit video from fast external SSDs, run several high-refresh-rate monitors from one cable, or use an external GPU.
We didn’t lab-test any ports for this article. Every speed, power, and display figure comes from official standards (Intel Thunderbolt, USB-IF, and VESA DisplayPort), laptop makers’ published spec sheets, and third-party guides linked inline, cross-checked for accuracy. Each section notes its source tier, and all prices are dated.
USB-C Is a Shape, Thunderbolt 5 Is a Promise
To see why two identical-looking ports can behave so differently, you have to separate the plug from the technology that travels through it. Once you do, the whole USB-C vs Thunderbolt 5 question gets a lot simpler.
What Does “USB-C” Actually Tell You?
USB-C is a connector design: a small, reversible, 24-pin oval. The USB Implementers Forum (USB-IF) published the first USB Type-C specification on August 11, 2014.
Here’s the catch. “USB-C” describes the shape, not the speed. A device with a USB-C port isn’t required to support any particular USB data standard, fast charging, or video output.
So when a laptop spec sheet lists only “USB-C port,” it tells you what plugs in, but not what that port can actually do. Our guide to laptop ports and connectors covers HDMI and the rest of the lineup, too.
Which Speed Tiers Hide Behind the Same Plug?
Depending on the chip wired behind it, a USB-C port can run any of these data standards, based on spec breakdowns published by Anker and Plugable:
- USB 2.0: 480Mbps (fine for a mouse, painfully slow for a backup)
- USB 3.2 Gen 1: 5Gbps
- USB 3.2 Gen 2: 10Gbps
- USB 3.2 Gen 2×2: 20Gbps
- USB4: 40Gbps
- USB4 Version 2.0: 80Gbps
speed spread between the slowest and fastest ports that share the same USB-C plug
The USB-IF has tried to reduce the confusion. Alongside USB4 Version 2.0 in 2022, it introduced new logos and marketing names that state a port’s maximum speed, such as “USB 40Gbps” or “USB 80Gbps.” Not every laptop maker prints those logos next to the port, though, so the spec sheet is still your most reliable guide.
What Does Thunderbolt 5 Add on Top?
Thunderbolt 5 is Intel’s certified connection standard, and it runs through that same USB-C connector. Intel officially unveiled it in September 2023 along with its “Barlow Ridge” controller chips.
It’s built on the USB4 Version 2.0, DisplayPort 2.1, and PCIe Gen 4 standards. The key difference is that Thunderbolt 5 makes the best features mandatory. According to Intel’s Thunderbolt technology overview and AnandTech’s coverage of the launch details, every Thunderbolt 5 laptop port must support:
- 80Gbps in both directions, plus a “Bandwidth Boost” mode that sends up to 120Gbps one way (with 40Gbps coming back) for display-heavy setups
- PCIe Gen 4 x4 at 64Gbps, the data path used by external SSDs and external graphics cards (eGPUs)
- DisplayPort 2.1 for high-resolution, high-refresh monitors
- At least 140W of laptop charging, with support for up to 240W
A plain USB-C label tells you what might be possible. A Thunderbolt 5 label tells you what’s guaranteed. That certainty is what you’re paying extra for.

USB-C vs Thunderbolt 5: Side-by-Side Comparison
Now that you know USB-C is the plug and Thunderbolt 5 is the guarantee, the next question is how big the gap really is. The table below lines up a typical USB-C port, a USB4 port, and a Thunderbolt 5 port on the four things that matter most on a laptop: speed, charging, monitors, and expansion.
| Feature | Typical USB-C (USB 3.2) | USB4 | Thunderbolt 5 |
|---|---|---|---|
| Max data speed | 5–20Gbps | Up to 40Gbps | 80Gbps both ways; up to 120Gbps with Bandwidth Boost ✓ |
| Guaranteed minimum speed | None | 20Gbps (basic USB4) | 80Gbps ✓ |
| Laptop charging | Optional; up to 100W (USB PD 3.0) or 240W (USB PD 3.1) if supported | Optional; no required minimum | 140W minimum; up to 240W ✓ |
| External monitors | Optional (DisplayPort Alt Mode); often one 4K at 60Hz | Varies by laptop | Up to three 4K at 144Hz or two 8K at 60Hz ✓ |
| PCIe (eGPUs, fast SSDs) | Not supported | Optional | Required: 64Gbps (PCIe Gen 4 x4) ✓ |
| Daisy-chaining | Through USB hubs (bandwidth is shared) | Through hubs and docks | Up to six Thunderbolt devices on one port ✓ |
| Certification | Optional USB-IF logo | Optional USB-IF logo | Required Intel certification ✓ |
Sources: Intel and AnandTech (Thunderbolt 5 requirements), Anker (USB-C tiers, displays, daisy-chaining), Cable Matters (USB4 power), and Kingston (basic USB4 at 20Gbps).
Thunderbolt 5 doubles the 40Gbps ceiling of Thunderbolt 4 and USB4, and Bandwidth Boost pushes one direction to 120Gbps for demanding monitor setups.
How Much Faster Is Thunderbolt 5 Than USB-C?
The headline gap is simple. A typical USB 3.2 port tops out between 5Gbps and 20Gbps, while Thunderbolt 5 guarantees 80Gbps. That’s four to sixteen times more bandwidth through the same-shaped hole.
Bandwidth Boost is the one asterisk. It reroutes lanes so one direction gets 120Gbps and the other drops to 40Gbps. It mainly kicks in for high-resolution displays, not everyday file copies.
Can Every USB-C Port Charge a Laptop?
Plenty of USB-C laptop ports can charge, but nothing in the base USB standards says they must. USB4 doesn’t set a power requirement either, according to Cable Matters.
Thunderbolt 5 does. Every certified port must handle at least 140W, enough for most performance laptops, and it can scale to 240W.
How Many External Monitors Can Each Port Run?
This is where many buyers feel the difference first. A basic USB-C port may not output video at all, and when it does, it’s often limited to one 4K screen at 60Hz.
Thunderbolt 5 can drive three 4K monitors at 144Hz or two 8K monitors at 60Hz from one port, per Anker’s spec summary. That’s a full creator desk on a single cable.
Do eGPUs and Fast External SSDs Need Thunderbolt?
External graphics cards and the fastest NVMe drive enclosures need PCIe, the same data path your laptop uses internally. Regular USB 3.2 ports don’t carry it at all.
Thunderbolt 5 doubles PCIe bandwidth to 64Gbps, up from 32Gbps on Thunderbolt 4. For eGPU users, that’s the upgrade that matters most, because graphics cards are especially sensitive to PCIe bandwidth.
Thunderbolt 4 vs Thunderbolt 5: Is the Upgrade Worth It?
If you already own Thunderbolt 4 gear, this is the comparison that decides whether an upgrade is worth it. Every row below is a certified minimum or maximum, not an optional extra.
| Feature | Thunderbolt 4 | Thunderbolt 5 |
|---|---|---|
| Data speed | 40Gbps both ways | 80Gbps both ways; up to 120Gbps with Bandwidth Boost ✓ |
| PCIe bandwidth | 32Gbps | 64Gbps (PCIe Gen 4 x4) ✓ |
| External displays | Two 4K at 60Hz or one 8K | Up to three 4K at 144Hz or two 8K at 60Hz ✓ |
| DisplayPort version | DisplayPort 1.4 | DisplayPort 2.1 ✓ |
| Laptop charging | Up to 100W (required on at least one port) | 140W minimum; up to 240W ✓ |
| Power for bus-powered accessories | At least 15W | At least 15W |

Thunderbolt 5 vs USB4 v2: Same 80Gbps, Different Guarantees
The comparison above raises a fair question. If USB4 Version 2.0 also reaches 80Gbps, why does Thunderbolt 5 exist at all? The answer is the same theme from earlier: one standard allows features, the other requires them.
Both run on the same underlying technology. In fact, Intel’s design makes Thunderbolt 5 a superset of USB4 v2, so it can do everything USB4 v2 can. Where they split is philosophy. As Faceofit describes it, USB4 is a flexible open standard, while Thunderbolt 5 is a licensed, certified performance guarantee.
| Feature | USB4 Version 2.0 | Thunderbolt 5 |
|---|---|---|
| 80Gbps on every port | Not guaranteed; a “USB4” port may run at 40Gbps or 20Gbps | Required ✓ |
| Bandwidth Boost (120Gbps one way) | Optional | Required ✓ |
| Laptop charging | No minimum | 140W minimum ✓ |
| PCIe for eGPUs and fast SSDs | Optional | Required (64Gbps) ✓ |
| DisplayPort video | Display output supported on hosts; DisplayPort 2.1 top rates optional | DisplayPort 2.1 required ✓ |
| Power for bus-powered accessories | As low as 7.5W on basic USB4 | At least 15W ✓ |
| Certification | Optional USB-IF logo program | Required Intel certification |
| Licensing | Royalty-free ✓ | Licensed by Intel |
Sources: Faceofit (optional vs. mandatory features), USB-IF (USB4 specification overview), AnandTech (Thunderbolt 5 requirements), Cable Matters (USB4 power), Club386 (15W accessory power), and Kingston (basic USB4 accessory power and licensing).
Here’s what that looks like in real life. Two laptops might both say “80Gbps USB-C.” The Thunderbolt 5 model will charge at 140W or more and run an eGPU. The USB4 v2 model might do both, but you’d have to dig through the spec sheet to know.
What Does the “USB 80Gbps” Logo Mean?
Since 2022, USB-IF guidelines have pushed port logos to state the maximum transfer speed, and cable logos to show the maximum charging wattage as well. So a “USB 80Gbps” mark tells you the top speed is certified.
What it doesn’t tell you is which optional extras are included.
Treat the “USB 80Gbps” logo as a speed promise, not a feature promise. Check the spec sheet for charging wattage, monitor support, and PCIe if those matter to you.
Do AMD and Snapdragon Laptops Get Thunderbolt 5?
Thunderbolt is an Intel-certified standard, so most non-Intel Windows laptops list USB4 ports instead. Qualcomm’s Snapdragon X2 Elite platform, for example, supports up to three USB4 ports at 40Gbps.
That’s fast, and many Thunderbolt 4 docks work on USB4 hosts. But a USB4 port isn’t Thunderbolt-certified, so feature parity isn’t guaranteed. ThunderboltLaptop’s AMD dock guide gives the same advice: confirm your exact model documents USB4 display support and charging input before buying a dock.

How to Tell Which Port Your Laptop Has
Knowing the difference on paper only helps if you can spot it on your own laptop. You don’t need any tools. Between the icons by the port, the spec sheet, and a quick system check, you can confirm what you have in about two minutes.
A quick visual guide to common laptop port markings. When there’s no icon, the spec sheet or a system check is the only reliable way to know.
Can You Trust the Icon Next to the Port?
Thunderbolt ports are usually marked with a small lightning-bolt icon. According to storage maker ATTO’s Thunderbolt 5 tech brief, the version number is typically printed next to that icon on Thunderbolt 5 gear.
Icons are a helpful first clue, not proof. MacBooks, for example, don’t print icons next to their ports (Apple’s port identification guide shows them by shape instead), and some Windows makers skip them too.
What Should You Look for on the Spec Sheet?
Your laptop maker’s official spec page is the most reliable source. Look for these exact phrases next to each port:
- “Thunderbolt 5” or “up to 120Gb/s”: Thunderbolt 5
- “USB4 80Gbps” or “USB 80Gbps”: USB4 Version 2.0
- “Thunderbolt 4” or “USB4 40Gbps”: 40Gbps class
- “USB 3.2 Gen 2” or “10Gbps”: standard USB-C
Check every port separately. Many 2026 workstations, like the ThinkPad P1 Gen 8 and HP ZBook, pair two Thunderbolt 5 ports with one Thunderbolt 4 port, so the port you pick for your dock matters.
How Do You Check for Thunderbolt 5 on Windows 11?
Open Settings > Bluetooth & devices > USB > USB4 Hubs and Devices. This page lists your system’s USB4 capabilities and connected devices, according to ElevenForum’s Windows 11 tutorial.
If the page doesn’t appear, open Device Manager and look for a “USB4 Host Router” entry. No entry usually means no USB4 or Thunderbolt support on that machine. One heads-up: Intel’s older Thunderbolt Control Center app isn’t universally supported on Windows 11, so don’t rely on it.
How Do You Check for Thunderbolt 5 on a Mac?
Hold the Option key, click the Apple menu, and choose System Information. Then select Hardware > Thunderbolt/USB4. Mac owners on the MacRumors forums report that Thunderbolt 5 ports show a speed of “Up to 120 Gb/s” there.
As a quick rule, Apple’s current lineup splits by chip. The MacBook Pro with M5 Pro or M5 Max has three Thunderbolt 5 ports, while the base M5 MacBook Pro and M5 MacBook Air use Thunderbolt 4.
Source tier: Manufacturer Spec (Apple, Lenovo, and HP spec sheets, linked directly or as compiled by the linked guides) and Third-Party Published (ATTO, ElevenForum, iTechGuides, MacRumors user reports).
Cables, Docks, and the “Weakest Link” Rule
Finding a Thunderbolt 5 port on your laptop is only half the job. Real-world speed depends on the whole chain: the laptop port, the cable, and the device on the other end. The slowest part of that chain sets your real-world speed.
Even with a Thunderbolt 5 laptop and dock, a Thunderbolt 4 cable caps the whole connection at 40Gbps. Every link has to match to get full speed.
Is the Cable in Your Laptop Box Good Enough?
The cable that came with your laptop charger is usually built for power, not data. Accessory maker UGREEN notes that bundled charging cables are almost always USB 2.0, which can quietly cripple a docking station.
Short, high-quality passive 40Gbps cables (typically 0.8 meters, or about 2.6 feet, and shorter) can carry 80Gbps. For longer cables or full 240W charging, you’ll need a newer certified “USB 80Gbps” or Thunderbolt 5 cable, according to Faceofit. The table below matches the cable to the job:
| What You’re Doing | Cable You Need | What Happens With the Wrong Cable |
|---|---|---|
| Charging your laptop | A USB-C cable rated for your charger’s wattage (look for the watt rating on the logo) | A lower-rated cable can limit charging speed |
| One 4K monitor at 60Hz | USB 3.2 Gen 2 (10Gbps) | Works fine; you don’t need Thunderbolt for this |
| A Thunderbolt 4 dock | Thunderbolt 4 cable (40Gbps) | A basic USB-C cable may drop monitors, slow drives, or not detect the dock |
| A Thunderbolt 5 dock at full speed | Thunderbolt 5 cable (80Gbps) | A Thunderbolt 4 cable works but caps you at 40Gbps |
| Full 240W charging | Certified 240W (EPR) USB-C or Thunderbolt 5 cable | Charging falls back to a lower wattage |
Sources: UGREEN (use-case cable guidance), Faceofit (80Gbps and 240W cable requirements), and Club386 (wattage on USB-IF cable logos).
Do Thunderbolt 4 Docks Work on Thunderbolt 5 Laptops?
Yes. Thunderbolt 5 is backward compatible with Thunderbolt 4, Thunderbolt 3, and USB4 gear, as Plugable confirms. Your existing dock will work, but only at Thunderbolt 4 speeds and features.
The reverse is trickier. Plug a Thunderbolt device into a plain USB-C port and it may fall back to slower USB mode, or may not work at all, depending on the device.
Can Your Drive Be the Bottleneck?
A fast port can’t make a slow drive faster. If your external SSD is rated for 1,000MB/s, it’ll stay near that speed on any port, as Lemorele’s guide points out.
With fast NVMe drives, the gap is real. Rands in Repose’s USB guide estimates roughly 3,000MB/s over 40Gbps ports versus about 6,000MB/s over Thunderbolt 5, while noting the drive itself is often the limit. If you’re shopping for one, our best external SSD guide lists each drive’s rated speed.

Which 2026 Laptops Have Thunderbolt 5?
Once you know how to read a spec sheet, the next question is practical: which laptops you can actually buy with Thunderbolt 5 today. The list is growing, but it’s still concentrated at the high end. The table below lines up Thunderbolt 5 models against same-budget alternatives that use Thunderbolt 4.
| Price Tier | Laptop | Starting Price | Ports (per maker specs) | Best For |
|---|---|---|---|---|
| About $2,000–$2,500 | MacBook Pro 14 (M5 Pro) | $2,499 | 3x Thunderbolt 5 | Creators on macOS who want Thunderbolt 5 |
| Lenovo ThinkPad P1 Gen 8 | $2,189 (at launch) | 2x Thunderbolt 5 + 1x Thunderbolt 4 | Windows professionals who need a workstation | |
| Dell XPS 14 (2026) | $2,049.99 (at launch) | 3x Thunderbolt 4 | Thin-and-light Windows buyers who don’t need 80Gbps | |
| MacBook Pro 14 (M5) | $1,999 | 3x Thunderbolt 4 | Mac users with one or two monitors and standard docks | |
| About $3,500–$4,100 | Razer Blade 16 (2026), RTX 5070 Ti | $3,499.99 | 1x Thunderbolt 5 + 1x Thunderbolt 4 | Gamers and creators who want portability |
| MacBook Pro 14 (M5 Max) | $4,099 | 3x Thunderbolt 5 | Heavy video and 3D work on macOS |

Which Other 2026 Laptops Have Thunderbolt 5?
Beyond the table, these Windows models list Thunderbolt 5 on their manufacturer spec sheets, based on ThunderboltLaptop’s gaming and business-laptop roundups:
- ASUS ROG Strix SCAR 18: 2x Thunderbolt 5
- MSI Titan 18 HX: 2x Thunderbolt 5
- Alienware 18 Area-51: 2x Thunderbolt 5 on RTX 5070 Ti configurations and up
- Dell Pro Max and HP ZBook workstations: 2x Thunderbolt 5 + 1x Thunderbolt 4
Notice the pattern? These are almost all gaming rigs and mobile workstations, and several only offer Thunderbolt 5 on their higher-priced configurations.
Why Do Thin and Budget Laptops Still Skip Thunderbolt 5?
The main reason is hardware. Windows laptops need Intel’s dedicated Barlow Ridge controller chip for Thunderbolt 5. Tech writer Ed Tittel notes it’s poorly suited to smaller, lighter laptops because of its space and power demands.
That explains why even premium thin machines like the Dell XPS 14 and the base M5 MacBook Pro stick with Thunderbolt 4. In Tittel’s late-2025 survey, every Thunderbolt 5 laptop he found carried an MSRP above $2,000. Every Thunderbolt 5 laptop in our table above also starts above $2,000.

Who Should Pay for Thunderbolt 5 (and Who Shouldn’t)
With the laptop options laid out, the real decision comes down to how you work, the same question that drives any smart laptop buying decision. Thunderbolt 5 solves specific problems very well, but if you don’t have those problems, it’s money you won’t feel. Use the cards below to see which side you’re on.
Who Should Buy a Thunderbolt 5 Laptop?
Perfect Fit
Moving large footage files from fast external SSDs is where the doubled PCIe bandwidth pays off.
Perfect Fit
Three 4K screens at 144Hz is a Thunderbolt 5 job, as long as your laptop’s chip supports that many displays.
Perfect Fit
Graphics cards benefit most from the jump to 64Gbps PCIe.
Good Fit
At that price, the Thunderbolt 5 premium can be as small as about $140.
Who Can Skip Thunderbolt 5?
Not Ideal
If you mostly browse, stream, write, and join video calls, a good USB-C or Thunderbolt 4 port handles all of it.
Not Ideal
A 10Gbps USB-C connection can run a single 4K screen at 60Hz.
Not Ideal
Thunderbolt 4 or USB4 is the realistic, and perfectly capable, choice there. Our best laptops guide covers the strongest options.
Not Ideal
You’ll get USB4 instead, which is plenty for most docks and drives.
Thunderbolt 5 Pros and Cons
Pros
- Guaranteed 80Gbps on every certified port, with up to 120Gbps for displays
- At least 140W of laptop charging, up to 240W
- Drives up to three 4K 144Hz monitors or two 8K 60Hz monitors from one port
- 64Gbps PCIe for eGPUs and fast NVMe enclosures
- Backward compatible with Thunderbolt 4, Thunderbolt 3, USB4, and USB devices
Cons
- Mostly limited to laptops that start above $2,000
- Needs a Thunderbolt 5 dock and certified cable to reach full speed
- Not offered on AMD or Snapdragon laptops in 2026
- Your laptop’s chip, not the port, sets the real monitor limit
What Does Going Thunderbolt 5 Really Cost?
The laptop is only part of the bill. To actually use 80Gbps, you need Thunderbolt 5 gear on the other end of the cable, too. A typical setup adds three costs:
- Laptop premium: about $140–$500. Compare the ThinkPad P1 Gen 8 against the XPS 14, or the M5 Pro MacBook Pro against the base M5 model (prices from the table above). The bigger Apple gap also buys a faster chip, not just better ports.
- Thunderbolt 5 dock: about $300–$500. The Plugable TBT-UDT3 lists at $299.95 direct, while the CalDigit TS5 and TS5 Plus run $399.95 and $499.99, per a September 2026 comparison. Our best Thunderbolt docks guide compares them side by side.
- Certified cable: about $69. That’s the regular price of Apple’s 1-meter Thunderbolt 5 Pro Cable, which Macworld notes is sometimes on sale for less.
Key Takeaways
- All in, going Thunderbolt 5 costs roughly $500 to $1,070 more than buying a comparable Thunderbolt 4 laptop and keeping your current dock and cables.
- If you’d be buying a new Thunderbolt 4 dock anyway, the real difference is smaller.
- If you already own a good Thunderbolt 4 dock, you can keep using it on a Thunderbolt 5 laptop and upgrade the dock later.

Our Verdict: USB-C vs Thunderbolt 5
Should You Pay for Thunderbolt 5?
USB-C and Thunderbolt 5 aren’t really rivals. USB-C is the plug, and Thunderbolt 5 is the most capable standard that runs through it. The real question is whether you need what Thunderbolt 5 guarantees: 80Gbps speeds, 140W-plus charging, three high-refresh 4K monitors, and full-speed PCIe for eGPUs and fast drives.
For most people in 2026, the honest answer is not yet. Thunderbolt 4 and USB4 handle a dock, one or two monitors, and everyday drives with ease, and they’re available on laptops well under $2,000.
Thunderbolt 5 earns its premium for video editors, multi-monitor power users, and eGPU owners, especially if you’re already shopping in the $2,200-plus range where it often comes standard. Just budget for a matching dock and a certified cable, or the weakest link will cap your speed.
Bottom line: if your next laptop costs over $2,000 and you work with big files or multiple screens, choose a Thunderbolt 5 model. Otherwise, save the money and buy a laptop with solid Thunderbolt 4 or USB4 ports.
