CalDigit TS4 vs Cable Matters Thunderbolt 4 Dock Comparison 2026

CalDigit TS4 vs Cable Matters Thunderbolt 4 Dock: Two Very Different TB4 Buys

The CalDigit TS4 and Cable Matters Thunderbolt 4 Dock both connect over Thunderbolt 4 at 40 Gbps, charge a laptop through the host cable, and support dual 4K displays in the right setup. That is where the similarities start to split.

The CalDigit TS4 is the premium, all-around pick. It scores 9.2/10 in our review, includes 18 ports, adds 2.5 Gigabit Ethernet, uses UHS-II SD and microSD readers, and works cleanly across macOS, Windows, ChromeOS, and Linux. The Cable Matters TB4 Dock scores 7.2/10 and is more targeted: it gives Windows users a lower-cost way to get dual 4K@60Hz displays with both HDMI and DisplayPort built in.

The short verdict: The CalDigit TS4 wins for most people because it is more complete, more Mac-friendly, and better equipped for high-end desks. Choose the Cable Matters dock if you mainly use Windows, want direct HDMI and DisplayPort outputs, and care more about price than premium extras.

Quick Specs Comparison

Design and Desk Fit

The CalDigit TS4 uses a premium aluminum enclosure with strong thermal behavior and the kind of build quality that fits a permanent desk setup. Its port layout is also more flexible for power users: frequently touched ports sit up front, while display, Ethernet, and host connections stay out of the way on the back.

The Cable Matters dock takes a more practical value approach. Its matte black plastic chassis is less premium, but the built-in HDMI and DisplayPort outputs make it easy to wire up existing monitors without adapters. That matters if your desk already has HDMI or DisplayPort cables in place and you do not want to add USB-C display adapters.

Design winner: CalDigit TS4. The Cable Matters dock is practical, but the TS4 has the better enclosure, broader port layout, and more premium feel.

Port Selection

The TS4 is the more complete dock. It provides three Thunderbolt 4 downstream ports, three USB-C 3.2 ports, five USB-A 3.2 ports, DisplayPort 1.4, 2.5 Gigabit Ethernet, three audio connections, and UHS-II SD plus microSD readers. It is built for desks with fast storage, card workflows, wired networking, audio gear, and multiple USB devices.

The Cable Matters dock has a narrower but useful port mix. Its big advantage is direct video: two HDMI 2.0 ports and two DisplayPort 1.4 ports. It also has six USB-A ports, one USB-C 3.2 port, Gigabit Ethernet, a combo audio jack, and SD plus microSD readers. If your setup is mostly keyboard, mouse, webcam, headset, and two standard 4K monitors, it covers the basics well.

The differences show up when you need speed or expansion. The TS4 has Thunderbolt downstream ports for high-speed storage and display adapters, 2.5GbE for faster local networking, and UHS-II card readers rated at 312 MB/s. The Cable Matters dock is limited to 1GbE and UHS-I card reader speeds.

Port winner: CalDigit TS4. Cable Matters wins on built-in HDMI count, but CalDigit wins on total capability, Thunderbolt expansion, networking, audio, and card-reader speed.

Display Support

Both docks can run dual 4K@60Hz displays, but the host platform matters much more for the Cable Matters dock.

The CalDigit TS4 supports dual 4K@60Hz via DisplayPort 1.4 and Thunderbolt 4 video output. On Mac, dual displays require an M1 Pro, M1 Max, or later chip because base Apple Silicon Macs only support one external display natively. On Windows, it can also run a single 8K@30Hz display.

The Cable Matters dock supports dual 4K@60Hz on Windows through any mix of its HDMI 2.0 and DisplayPort 1.4 outputs. That is convenient because you can connect two common monitors without buying adapters. The catch is macOS: the dock relies on DisplayPort MST for dual display output, and macOS does not support MST. That means Mac users get one external monitor only.

Display winner: CalDigit TS4 for Mac and high-end flexibility. Cable Matters for Windows users who want direct HDMI and DisplayPort ports.

Power Delivery

This category is close on paper. The CalDigit TS4 delivers up to 98W to the host laptop, while the Cable Matters Thunderbolt 4 Dock delivers up to 96W.

Both numbers are enough for most ultrabooks, 13-inch and 14-inch MacBook Pro models, many 15-inch laptops, and light-to-moderate 16-inch MacBook Pro use. Neither dock is meant to replace a high-wattage gaming laptop charger under full load.

Power winner: CalDigit TS4, narrowly. The 98W rating is slightly higher, but the real-world difference between 98W and 96W is small.

macOS and Windows Compatibility

This is one of the clearest divides.

The TS4 is one of the safest Thunderbolt 4 docks for Mac users. It requires no drivers, works natively on macOS, and CalDigit has a strong track record with firmware updates. Windows, ChromeOS, and Linux support are also listed in the product YAML.

The Cable Matters dock also requires no drivers and works well on Windows. Its limitation is display architecture. On macOS, USB, Ethernet, audio, card readers, and charging work, but display output is limited to one external monitor because the dock uses MST for its multi-monitor behavior.

Compatibility winner: CalDigit TS4. The Cable Matters dock is a good Windows pick, but the Mac display limitation is too important to ignore.

Pricing and Value

The Cable Matters Thunderbolt 4 Dock has the obvious price advantage. Its $199.99 MSRP is far below the TS4’s $379.99 MSRP, and the dock still provides Thunderbolt 4, 96W charging, six USB-A ports, direct HDMI and DisplayPort outputs, Ethernet, audio, and card readers.

The CalDigit TS4 justifies its higher price by giving you more durable hardware, more high-speed connectivity, better Mac support, 2.5GbE, UHS-II card readers, and a two-year warranty instead of one year. If those features replace separate adapters or prevent a display compatibility headache, the premium is easy to defend.

Value winner: Depends on your setup. Cable Matters is the better budget value for Windows dual-monitor desks. CalDigit is the better long-term value for Mac users, creators, and anyone who needs a truly complete dock.

Verdict: CalDigit TS4 Wins, But Cable Matters Has a Clear Niche

The CalDigit TS4 is the better Thunderbolt 4 dock overall. It wins on score, port depth, Mac compatibility, Ethernet speed, card-reader speed, warranty length, and premium build quality. It is the safer recommendation if you want one dock that can handle almost any serious desk setup.

The Cable Matters Thunderbolt 4 Dock is not trying to beat the TS4 feature for feature. Its appeal is simpler: dual 4K Windows display support, both HDMI and DisplayPort built in, lots of USB-A, 96W charging, and a much lower MSRP. For a Windows home office, that can be exactly the right tradeoff.

Choose the CalDigit TS4 if:

• You use a MacBook and want the best chance of clean native support
• You need dual 4K displays without relying on DisplayPort MST
• You want 2.5 Gigabit Ethernet
• You use fast SD or microSD cards and want UHS-II speeds
• You need Thunderbolt downstream ports for storage, displays, or expansion
• You want the best overall Thunderbolt 4 dock in this matchup

Choose the Cable Matters Thunderbolt 4 Dock if:
