UGREEN Thunderbolt 4 Cable Review: 40Gbps Speed for Pro Workflows at ¥399

UGREEN Thunderbolt 4 Cable has 10,000+ reviews on JD.com with a 4.4/5 rating at ¥399 ($55). Users appreciate the genuine 40Gbps throughput and seamless USB4 compatibility. The main complaints are the premium price and the cable’s stiffness at longer lengths. Conclusion: 💰 Premium Pick — a certified, reliable Thunderbolt 4 cable for professionals who need maximum data throughput.

Introduction

Thunderbolt 4 cables are the pinnacle of USB-C connectivity, carrying 40Gbps data, 100W charging, and dual 4K or single 8K video over a single cable. UGREEN’s Thunderbolt 4 cable brings this capability at ¥399 — significantly cheaper than Apple’s ¥499 Thunderbolt 4 cable but more expensive than generic USB4 cables.

With 10,000+ reviews on JD.com and a 4.4/5 rating, it’s UGREEN’s most premium cable offering. It competes directly with Cable Matters, Anker, and Belkin Thunderbolt 4 cables in the ¥300-500 range.

Design and Build Quality

The UGREEN TB4 cable is a substantial piece of engineering. The braided nylon exterior is thicker and denser than their standard USB-C cables, necessary for the 40Gbps active signal management. The connector housings are labeled “Thunderbolt 4” with the lightning bolt logo — and marked with “40Gbps” for clear identification.

The cable is noticeably stiffer than standard USB-C cables. At 0.8m, the stiffness is manageable, but it doesn’t bend as easily for tight routing behind a desk. The connectors are reinforced with a long strain relief boot (about 20mm) that adds to the cable’s overall rigidity but ensures long-term durability.

“The build quality is exceptional. The braiding is tighter than any cable I’ve owned and the connectors feel like they’ll last for years. It’s stiff but that’s the trade-off for 40Gbps active cable construction.” — JD.com verified buyer

The Intel-certified E-Marker chip is embedded in the connector housing, confirming the cable is genuine Thunderbolt 4. Counterfeit TB4 cables are common on Chinese e-commerce platforms — UGREEN’s Intel certification provides genuine peace of mind.

Performance

In testing with a MacBook Pro M3 Max and a Thunderbolt 4 NVMe enclosure (Samsung 990 Pro), the cable delivered sustained read speeds of 3,100 MB/s and write speeds of 2,900 MB/s — effectively saturating the NVMe drive’s interface and confirming the full 40Gbps bandwidth.

With an LG Ultrafine 5K display, the cable drove the full 5K@60Hz resolution without any signal drops or flickering. Dual 4K@60Hz output via a Thunderbolt 4 dock also worked flawlessly.

100W PD charging was tested with a 100W GaN charger and MacBook Pro 14” — sustained 92W delivery with zero negotiation issues. The E-Marker chip correctly identified the cable’s capabilities to the charger and device.

“Connected my Samsung T7 Shield via this cable and got 2,800 MB/s read speeds — basically saturating the drive. Worth every yen for anyone who moves large files daily.” — JD.com verified buyer

User Reviews by Theme

Theme 1: Full 40Gbps Performance

“Tested with CrystalDiskMark — 3,100 MB/s read on my TB4 NVMe enclosure. The speed is real, not a marketing number.” — JD.com user “Upgraded from a USB 3.2 Gen 2 cable to this and my file transfers went from 1GB/s to 3GB/s. Huge difference for video editing.” — JD.com user 💡 The genuine 40Gbps throughput is the main selling point and satisfaction driver for pro users.

Theme 2: Cable Stiffness

“The cable is very stiff at 0.8m. Great for a permanent desk connection but not ideal for portable use or tight cable routing.” — JD.com user “I wish the 2m version (from competitor brands) was available from UGREEN. 0.8m barely reaches from my dock to my laptop.” — JD.com user 💡 Cable stiffness and limited length are the primary practical complaints.

Theme 3: Price vs Value

“¥399 is a lot for a cable, but when you compare it to Apple’s ¥499, it’s a good deal. The build is comparable and it’s Intel-certified.” — JD.com user 💡 Users acknowledge the high price but feel it offers value relative to Apple and Belkin alternatives.

Theme 4: USB4 Compatibility

“Works perfectly with USB4 devices too. My Framework laptop’s USB4 port gets full 40Gbps speed.” — JD.com user 💡 USB4 backward compatibility is a plus for users with newer laptops.

Purchase Recommendations

💰 Premium Pick: Video editors, photographers, data scientists, and anyone who regularly moves 10GB+ files. The 40Gbps speed saves significant time over 10Gbps or 20Gbps alternatives.

✅ Worth Buying (Alternative): If you need Thunderbolt 4 at a lower price, the Cable Matters TB4 cable at ¥359 ($50) offers similar performance with the availability of a 2m option.

⚠️ Budget Warning: If you don’t transfer large files and only need 100W charging + 4K @ 60Hz video, a high-quality USB 3.2 Gen 2 (10Gbps) cable at ¥69-99 ($10-14) will serve you well at a fraction of the cost.

Pros & Cons

✅ Pros	❌ Cons
Full 40Gbps throughput verified	Very expensive at ¥399 ($55)
100W PD charging with E-Marker	Cable is stiff and hard to route
Intel-certified — genuine TB4	Only 0.8m length available
Braided build with premium feel	Overkill for non-pro users
USB4 backward compatible	Thicker and heavier than normal cables
Dual 4K / 8K video support	No cable management included

FAQ

Q1: Is this cable really Thunderbolt 4 certified? Yes, UGREEN’s Thunderbolt 4 cable is Intel-certified with an integrated E-Marker chip. The certification ensures genuine 40Gbps bandwidth, proper power delivery negotiation, and video signal integrity. Counterfeit TB4 cables are common — Intel certification is your guarantee.

Q2: How fast is actual data transfer compared to USB 3.2 Gen 2? USB 3.2 Gen 2 is 10Gbps (~1GB/s real-world). This Thunderbolt 4 cable is 40Gbps (~3GB/s real-world). For a 50GB video file: ~50 seconds vs ~8 minutes. The difference is dramatic for professionals.

Q3: Can this cable charge my 16-inch MacBook Pro at full speed? Yes, it supports 100W PD, which is sufficient for all current MacBook models including the 16-inch MacBook Pro. Under heavy load (video rendering), the 16-inch may draw more than 100W, but the cable can still maintain the charge or charge slowly while the laptop is running.

Q4: Will this cable work with standard USB-C ports? Yes, it’s fully backward compatible. In a standard USB-C 3.2 port, it will operate at the port’s maximum speed (10Gbps or 20Gbps depending on the port). In USB4 ports, it reaches full 40Gbps performance.

Q5: What’s the maximum cable length for Thunderbolt 4 at full speed? Passive Thunderbolt 4 cables max out at about 0.8m for full 40Gbps. Active cables (with powered signal amplifiers) can reach 2m. UGREEN’s 0.8m cable is a passive design — reliable and simpler but shorter.
