This article covers [Intel 認証] Cable Matters 20Gbps アクティブ Thunderbolt 3 ケーブル 2m ブラック (× 2).

Overview

The Cable Matters 20Gbps Active Thunderbolt 3 Cable is an Intel-certified high-performance cable that delivers up to 20Gbps data transfer—twice the speed of USB 3.1 Gen 2. It supports 4K@60Hz video output, up to 100W Power Delivery charging, and comes in a convenient 2-pack. The active circuitry ensures signal integrity across the full 2-meter length, making it a reliable choice for demanding setups.
This cable is compatible with Thunderbolt 3 and USB-C devices, including laptops, tablets, docks, and monitors. It's designed for users who need a single cable to handle data, video, and power simultaneously—a true all-in-one connection.

Connectivity & Compatibility

The reversible USB Type-C connector works with both Thunderbolt 3 and USB-C ports. In Thunderbolt 3 mode, it achieves 20Gbps bandwidth; in USB-C mode, it falls back to 10Gbps (USB 3.1 Gen 2) or 5Gbps. Display output supports 4K@60Hz via DisplayPort Alternate Mode, and daisy-chaining up to 6 devices is possible.
Power delivery is robust: up to 60W for laptops and 15W for bus-powered devices, with full 100W support when used with a PD charger. The cable is bi-directional, so it works regardless of which end is connected to the power source.
Compatible devices include: 2016+ MacBook Pro/Air, Dell XPS 13/15, ASUS ROG laptops, Acer Predator, Intel NUC, Samsung Galaxy S8+, LG Gram, and many other Thunderbolt 3 or USB-C equipped systems. Note that Thunderbolt 4 ports can use this cable but are limited to 20Gbps (not 40Gbps). USB-C-only devices will not achieve the maximum 20Gbps speed.

Product Info

The 2-pack (black) retails around ¥7,758 on Japanese online retailers, offering excellent value at roughly ¥3,900 per cable. Cable Matters provides an 18-month warranty. The package includes two 2m cables and a quick-start guide.
Market positioning: mid-to-high tier. The Intel certification and active design justify the premium over passive or non-certified cables. For users who require consistent 20Gbps performance at 2m length, this is a top choice.

Best Use Cases

  • Creative professionals working with 4K video or large files: connect a laptop to a high-resolution monitor and an external SSD simultaneously via daisy-chaining or a Thunderbolt 3 dock. The 20Gbps bandwidth avoids bottlenecks during RAW editing or timeline scrubbing. However, maximum speed requires a Thunderbolt 3 host.
  • Users with a dual-monitor Thunderbolt 3 setup: daisy-chain two 4K monitors with a single cable for a clean desk. The cable also powers the monitors' USB hubs via bus power.
  • Mobile workers with multiple devices: keep one cable at the office and one at home. The 100W PD support charges most laptops, eliminating the need for a separate power brick. Overkill if you only need basic charging or USB 2.0 speeds.
