CalDigit TS4 vs OWC Thunderbolt Go Dock

CalDigit TS4 vs OWC Thunderbolt Go Dock

The CalDigit TS4 and OWC Thunderbolt Go Dock are both native Thunderbolt 4 docks. They use a 40 Gbps host connection, work without a display driver, provide 2.5 Gigabit Ethernet, and support two external 4K displays at 60Hz when the computer can drive them. The deciding factor is not the Thunderbolt standard. It is how each company has used the available bandwidth and space.

CalDigit built the TS4 as a desk-first expansion dock. It has 18 ports, 98W charging, three downstream Thunderbolt 4 ports, UHS-II readers for both SD and microSD media, and separate combo, headphone, and microphone connections. Its 9.2 score reflects that unusually broad port selection.

OWC takes a more mobile approach. The Go Dock puts a 120W power supply inside its aluminum housing, so it needs a normal two-prong AC cable rather than a separate power brick. Its 11-port layout still includes HDMI 2.1, 2.5GbE, UHS-II SD, two downstream Thunderbolt 4 ports, and 90W host charging. That makes it useful for someone who alternates between an office desk, home desk, studio, or hotel and wants one less bulky piece in the bag.

The short answer is simple. The TS4 is the better dock for most fixed workspaces because it has more expansion, more charging headroom, and a higher score. The Go Dock earns its place when the built-in power supply solves a packing problem you actually have.

Quick specs comparison

The table points to the central trade-off. The TS4 is built for peripherals. The Go Dock keeps enough of the premium feature list to be useful away from one desk, then uses its remaining space for the internal power supply.

Ports and everyday expansion

The CalDigit TS4 is ahead on quantity and flexibility. It has three downstream Thunderbolt 4 ports, three USB-C 3.2 ports, and five USB-A 3.2 ports. The direct DisplayPort 1.4 output, wired networking, three audio connections, and two UHS-II card readers take its listed total to 18 ports. A desk with an external SSD, a webcam, an audio interface, input devices, card media, and one or two displays is exactly where this layout pays off.

Those three downstream Thunderbolt ports matter if you attach high-speed storage, a Thunderbolt display, or a chain of peripherals. The TS4 also exposes more ordinary USB ports without asking you to choose between a keyboard, a phone cable, a reader, or an external drive. Its card-reader setup is stronger for photographers and video users who work with both SD and microSD cards. Both readers are listed at UHS-II speeds up to 312 MB/s.

The OWC Go Dock is less expansive but not bare. It provides two downstream Thunderbolt 4 ports, one USB-C 3.2 port, two USB-A 3.2 ports, one USB-A 2.0 port, HDMI 2.1, a 3.5mm headphone output, 2.5GbE, and an SD 4.0/UHS-II reader. It is a sensible selection for a laptop, monitor, external drive, Ethernet cable, basic peripherals, and an SD card workflow.

There are practical differences beyond the raw count. OWC gives you HDMI 2.1 directly. The TS4 gives you DisplayPort 1.4, and its YAML notes that HDMI users will need a DisplayPort cable or adapter. That can make the Go Dock easier to connect to a TV or an HDMI-only monitor. The TS4 has three audio connections where the Go Dock has one headphone output, so the CalDigit is more convenient for a wired headset, microphone, or separate speakers without an extra adapter.

Port winner: CalDigit TS4. It has seven more listed ports, one more downstream Thunderbolt 4 port, more USB expansion, a microSD reader, and a fuller audio setup. Choose the OWC layout if its HDMI output and smaller peripheral list fit your desk, not because it is the larger expansion dock.

Displays and host limits

Both docks support up to two 4K displays at 60Hz through a capable Thunderbolt host. That is the common configuration for a serious two-monitor desk. Neither dock uses DisplayLink, so there is no extra display driver requirement for normal use. The computer still controls the display ceiling.

The TS4 lists one 8K display at 30Hz through DisplayPort 1.4 on Windows, one 4K display at 60Hz, or two 4K displays at 60Hz. Its dual-display note calls out the Mac requirement directly: M1 Pro, M1 Max, or later is needed for two external displays. Base M1, M2, and M3 MacBook Air and Pro models are limited to one external display by Apple hardware, not by the dock.

The Go Dock lists a wider set of high-resolution modes, subject to a compatible host, cable, display, and DisplayPort 1.4 with DSC where required. OWC lists single 8K at 60Hz, single 4K at 120Hz, dual 4K at 60Hz, and dual 5K at 60Hz on capable Thunderbolt systems. Its HDMI 2.1 port is convenient, but these modes should not be read as a promise that every USB-C laptop will reach them. The product YAML says non-Thunderbolt USB-C hosts can have reduced bandwidth and display support, and that USB-C ports without DisplayPort Alt Mode do not provide external monitor output.

Both products share the same important Apple caveat. A base M-series Mac remains a one-display machine with either native Thunderbolt dock. Users who need multiple external screens from that host should look for a DisplayLink alternative instead. Our best docks for dual monitors page is a useful starting point for that kind of setup.

Display winner: depends on the target setup. The Go Dock has more ambitious listed modes and a direct HDMI 2.1 output. The TS4 has a direct DisplayPort 1.4 output and the same practical dual-4K desk target. Check the laptop’s graphics and port specification first, especially with MacBooks and USB-C-only Windows machines.

Charging and the built-in power supply

The TS4 provides up to 98W of USB-C Power Delivery. CalDigit says this is enough to charge a 16-inch MacBook Pro during normal use, although the product notes that Apple’s 140W MagSafe adapter is faster for maximum charging. It also gives 15W to each of its downstream Thunderbolt 4 ports and 7.5W to the USB-C 3.2 and USB-A 3.2 ports.

The Go Dock provides up to 90W to the laptop and up to 15W through each downstream Thunderbolt port. Its own notes describe 90W as sufficient for most MacBook and Thunderbolt ultrabook workflows, while warning that higher-power workstation laptops may drain or charge slowly during sustained CPU or GPU work. The eight-watt difference will not transform a light office workload, but the TS4 has the better headroom when the laptop is under load.

Where OWC wins is cable management away from a permanent desk. The dock’s 120W power supply lives inside the aluminum enclosure. You bring the dock and its normal AC lead instead of a dock, a power brick, and the brick’s wall cable. It still needs wall power and it is not a tiny hub. At about 2.09 lb, the Go Dock is large and heavy for travel. The benefit is cleaner packing for people who already carry a capable dock, not a pocketable accessory.

The TS4 uses an external power adapter. That is less elegant in a bag, but it keeps the dock focused on desktop expansion. It is the better choice if the dock usually stays in one place and the extra ports are in use every day.

Charging winner: CalDigit TS4 for wattage, OWC Go Dock for travel packing. The TS4 has a 98W ceiling versus 90W. The OWC can remove a separate brick from a mobile workstation kit.

Networking, media, and audio

This is a close contest for networking. Both YAML files list 2.5GbE and 1GbE support, so either dock can connect to a faster local network when the router, switch, cable, and other device support it. For ordinary broadband, either is more than adequate. For local backups, large media transfers, or a NAS, 2.5GbE is a meaningful advantage over a basic Gigabit-only dock.

The TS4’s media setup is broader. It has UHS-II SD and microSD readers, each listed at up to 312 MB/s. The Go Dock has one UHS-II SD reader. If your work revolves around SD cards, both fit. If you routinely move files from drones, action cameras, or other microSD devices, the TS4 avoids another reader.

Audio is similarly one-sided. The TS4 includes a combo jack, a dedicated headphone output, and a dedicated microphone input. The Go Dock lists a 3.5mm headphone output. That can be enough for speakers or headphones, but the CalDigit gives a more useful arrangement for creators and desktop calls.

Media and audio winner: CalDigit TS4. The OWC covers the basics, while the TS4 supplies the additional reader and audio connections that reduce the number of add-on adapters on a crowded desk.

Compatibility, reliability, and value

The two docks are driverless native Thunderbolt products and both support macOS, Windows, ChromeOS, and Linux in their YAML compatibility sections. The Go Dock also lists Android support where the mobile device supports the required USB and display features. The TS4 lists full support on macOS Big Sur or later and Windows 10 or later, with ChromeOS and Linux support called out as well.

The TS4 has documented macOS sleep and wake behavior as an occasional issue. Its suggested fix is reconnecting the Thunderbolt cable or restarting the Mac, and CalDigit firmware updates have improved it. It also notes rare brief USB disconnects during display wake. The Go Dock lists warmth during charging and display use as common but low severity, HDMI or refresh-rate mismatches as occasional, and customer feedback that includes HDMI and connectivity complaints. OWC recommends confirming host limits and using certified cables for demanding display modes.

On score and sticker price, the TS4 is the more expensive and better-rated product: 9.2 at a $379.99 MSRP versus 8.1 at $199.99 for the Go Dock. Price alone does not settle the value question. A buyer who needs three downstream Thunderbolt ports, five USB-A ports, two card-reader formats, multiple audio connections, and 98W charging can use the TS4’s extra cost. A buyer who mostly needs a display, storage, Ethernet, a few peripherals, and less luggage clutter can reasonably value the Go Dock’s power design more highly.

Verdict: CalDigit TS4 for the desk, OWC Go Dock for the move

The CalDigit TS4 wins this comparison because it is the more complete Thunderbolt 4 dock for a fixed workstation. Its 9.2 score, 18-port layout, 98W charging, three downstream Thunderbolt ports, UHS-II SD and microSD readers, and dedicated audio connections give it more room to grow with a demanding desk setup. It costs more and does not include HDMI, but those are manageable trade-offs when you use the additional connectivity.

The OWC Thunderbolt Go Dock is not a stripped-down budget alternative. It keeps 2.5GbE, UHS-II SD, HDMI 2.1, two downstream Thunderbolt ports, and 90W charging in an 11-port Thunderbolt 4 dock. Its reason to exist is the internal 120W power supply. If moving between locations is part of the job, that design can be more useful than several extra desk ports.

Choose the CalDigit TS4 if:

• Your dock stays on one desk and you need the widest selection of ports.
• You use several USB drives, peripherals, or Thunderbolt devices at once.
• You need both SD and microSD UHS-II readers.
• You want up to 98W of host charging and three downstream Thunderbolt 4 ports.
• You use a wired microphone, headphones, and speakers without wanting separate USB audio hardware.

Choose the OWC Thunderbolt Go Dock if:

• You regularly move a Thunderbolt dock between home, office, studio, or travel locations.
• Packing a dock without a separate power brick matters more than maximum port count.
• You want direct HDMI 2.1, 2.5GbE, SD UHS-II, and two downstream Thunderbolt ports.
• Your laptop is comfortable with 90W charging.
• You can work within a more focused 11-port layout.
