This article focuses on what it can actually do, and where buyers tend to go wrong. ## Overview The Cable Matters Thunderbolt 5 Cable is an Intel-certified 1-meter USB-C to USB-C cable. Its rated data speed is 80Gbps in both directions, double the 40Gbps of Thunderbolt 4 and USB4. A video Bandwidth Boost mode can push up to 120Gbps toward the display. It also supports up to 240W USB PD 3.1 EPR charging, so one cable can carry data, video and power. The listed resolutions are 8K at 60Hz, 4K at 540Hz, dual 6K, dual 8K and triple 4K at 144Hz. These are ceilings the cable allows. What you actually get depends on the ports, displays and docks on each end. ## Compatibility Guide Both ends are USB-C. To reach 80Gbps or the 120Gbps boost, both the host and the device must support Thunderbolt 5. If one side is Thunderbolt 4, that link runs at 40Gbps. The cable is backward compatible with Thunderbolt 3/4, USB4, USB 3.2 Gen2x2 (20Gbps), USB 3.2 Gen2 (10Gbps) and ordinary USB-C devices. You can use it with Thunderbolt 4 gear you own now and keep it for a later upgrade. Video goes out over DisplayPort Alt Mode. Whether a multi-monitor setup works also depends on your GPU and the PC's output ports, so a new cable alone will not add displays. For 240W, both the charger and the laptop must support USB PD 3.1 EPR. With a 65W or 100W charger you get that charger's output. A laptop also accepts only its own maximum wattage, so a 240W cable does not guarantee faster charging. ## Product Info - Length: 1m - Data: 80Gbps bidirectional, 120Gbps video Bandwidth Boost - Power: up to 240W (USB PD 3.1 EPR) - Resolutions: 8K@60Hz, 4K@540Hz, dual 6K, dual 8K, triple 4K@144Hz - Connectors: USB-C on both ends - Certification: Intel Thunderbolt 5 Prices are snapshots. They change with sales and stock, so check each product page for the current price. Around the 3,000-yen mark is an approachable level for a Thunderbolt 5 cable. Intel certification matters because Thunderbolt cables look identical to ordinary USB-C charging cables. Check the sales page for warranty terms and what is in the box. ## Best Use Cases - **Video editors and 3D artists**: useful for moving large files to fast external storage, but 80Gbps only appears with Thunderbolt 5 storage or docks. - **Owners or soon-to-be owners of Thunderbolt 5 PCs and docks**: you need a cable like this to unlock the full speed, including high-resolution, high-refresh displays. - **Builders planning ahead**: it works with Thunderbolt 4 and USB4 gear today and can move to a newer setup later. ## Before You Buy - **120Gbps is not constant**: it is a video Bandwidth Boost and requires a compatible host and display. Treat 80Gbps as the sustained data rate. - **240W depends on the charger**: a 100W-class charger gives 100W or less. - **Only 1m**: it may be short for longer runs. Longer Thunderbolt cables can run slower, so do not daisy-chain extensions. - **Few compatible devices so far**: if your gear tops out at Thunderbolt 4, the extra headroom goes unused, and a Thunderbolt 4 cable may be cheaper. - **Listing data**: Amazon listing details can contain errors, so confirm the product by its title and photos. ### Product Disclosure (Amazon) - Manufacturer: Cable Matters - Seller: Cable Matters Japan - Fulfilled by: Amazon - ASIN: B0CP8K1C59 - Note: This article covers a manufacturer-made product based on Amazon listing details. ## FAQ **Q. Does it slow down on a Thunderbolt 4 port? ** A. The cable is not the limit; the port is. The link runs at 40Gbps and connects normally. **Q. Can I use it as a regular USB-C cable? ** A. Yes. It is backward compatible with USB-C devices for charging and data, though it costs more than a basic cable. **Q. Will every laptop charge at 240W? ** A. No. The charger's output and the laptop's accepted maximum decide it. **Q. Will the cable alone give me 8K or 4K at 540Hz? ** A. No. The GPU, PC and display must support it too. **Q. Who should skip it? ** A. People with no Thunderbolt 5 gear planned who are fine at 40Gbps or less. A Thunderbolt 4 cable is usually enough.
