CalDigit TS4 vs Anker Prime TB5 Dock Comparison 2026

CalDigit TS4 vs Anker Prime TB5: Proven Thunderbolt 4 vs Early Thunderbolt 5

The CalDigit TS4 and Anker Prime TB5 sit in the same premium price band, but they are built for different moments in the Thunderbolt upgrade cycle. The TS4 is the established Thunderbolt 4 benchmark: 18 ports, 98W charging, 2.5GbE, UHS-II card readers, and broad Mac, Windows, ChromeOS, and Linux support. The Anker Prime TB5 is newer and more forward-looking: Thunderbolt 5, 80 Gbps bandwidth, 140W host charging, HDMI 2.1, DisplayPort 2.1, and support claims aimed at dual 8K setups on compatible hosts.

The short verdict: The CalDigit TS4 is still the better dock for most people. It has the higher review score, more complete port selection, better card readers, broader compatibility, and a lower MSRP. The Anker Prime TB5 is the right pick only if your laptop has Thunderbolt 5, you need 140W charging, or you are building around very high-end display bandwidth.

Quick Specs Comparison

Design and Desk Setup

The CalDigit TS4 is the more mature desktop dock. Its aluminum enclosure, compact rectangular shape, and front-and-rear port layout are designed for everyday desk use. Frequently used ports such as USB, audio, and card readers are easy to reach, while display, Ethernet, power, and host Thunderbolt connections stay out of the way. CalDigit also has a long record of firmware updates for new Mac and Windows hardware.

The Anker Prime TB5 is more modern and compact in feel, with a built-in power supply that avoids a large external brick on the desk. That is a real usability win if you dislike bulky power adapters. It also looks more polished than many enterprise docks. Still, the Anker is an early Thunderbolt 5 product, and its value depends heavily on whether your laptop can use the extra bandwidth.

Design winner: Tie. The CalDigit has the proven aluminum build and smarter port depth. The Anker has the cleaner built-in power supply and newer premium design.

Port Comparison: TS4 Is Still the Connectivity King

The CalDigit TS4 wins the port count battle. It is built around breadth: three downstream Thunderbolt 4 ports, three additional USB-C 3.2 ports, five USB-A 3.2 ports, 2.5GbE, DisplayPort 1.4, three audio connections, and UHS-II SD plus microSD readers. If you have external drives, a webcam, a USB microphone, card media, audio gear, and multiple displays, the TS4 gives you more room before you need a hub.

The Anker Prime TB5 has fewer total everyday ports but newer high-end connectivity. Its two downstream Thunderbolt 5 ports are the headline, backed by two front USB-C 3.2 ports with 45W power delivery, three USB-A 3.2 ports, HDMI 2.1, DisplayPort 2.1, 2.5GbE, a combo audio jack, and SD plus microSD readers. That mix is strong, especially for users with Thunderbolt 5 storage or newer high-resolution displays.

The biggest practical difference is the card reader speed. The TS4 uses UHS-II readers rated in the product data at 312 MB/s. The Anker uses UHS-I readers, which is underwhelming for a $399.99 creator-focused dock.

Port winner: CalDigit TS4. The Anker has newer Thunderbolt and display standards, but the TS4 gives most users more usable connectivity every day.

Display Support: Anker Has the Ceiling, CalDigit Has the Safer Promise

On paper, the Anker Prime TB5 has the stronger display story. Its product data lists up to two 8K@60Hz displays on supported Thunderbolt 5 Windows systems and triple 4K@60Hz through the two downstream Thunderbolt ports plus HDMI or DisplayPort. That is beyond what a Thunderbolt 4 dock can promise.

The caveat is host support. Anker’s own compatibility notes say triple-display support depends heavily on the laptop, and very few laptops currently support that setup. Mac support is also more limited than the headline suggests. Base Apple Silicon MacBooks with M1, M2, or M3 standard chips still support only one external display over Thunderbolt because of Apple’s platform limits.

The CalDigit TS4 is less flashy but more predictable. It supports dual 4K@60Hz, and its product data lists single 8K@30Hz via DisplayPort 1.4 on Windows. Mac users still need an M1 Pro, M1 Max, or later chip for dual external displays, but this limitation is well understood, and the TS4 has a strong track record with Mac firmware support.

Display winner: Anker Prime TB5 for Thunderbolt 5 power users. CalDigit TS4 for predictable dual-monitor setups.

Power Delivery: Anker Wins on Wattage

This category is simple. The Anker Prime TB5 supports up to 140W host charging. That is a major advantage for demanding laptops, especially 16-inch machines or mobile workstations that can overwhelm 90W to 100W docks under load.

The CalDigit TS4 delivers up to 98W. That is still enough for many MacBook Pro and Windows ultrabook setups during normal use, and it is delivered through standard USB-C Power Delivery without a brand-specific charging requirement. But if your laptop can genuinely use more than 100W through USB-C, the Anker has the stronger spec.

Power winner: Anker Prime TB5. 140W beats 98W clearly.

Compatibility: CalDigit Covers More Real-World Laptops

The CalDigit TS4 is the safer compatibility choice. Its product data lists macOS, Windows, ChromeOS, and Linux support, and it works with Thunderbolt 3 and Thunderbolt 4 systems. That matters if you own an Intel Mac, an older Thunderbolt laptop, or mixed office hardware.

The Anker Prime TB5 is narrower. It is officially for Thunderbolt 5 and Thunderbolt 4 laptops, and the YAML explicitly lists Thunderbolt 3 laptops as not supported. Linux and ChromeOS are also not officially supported. For Windows users with a new Thunderbolt 5 laptop, that may not matter. For everyone else, it is a real buying risk.

Mac users should be especially careful. Anker lists macOS compatibility, but the product data notes that best compatibility may require newer macOS versions and that base M1, M2, and M3 chips remain single-external-display systems. The TS4 has similar base-chip display limits, but better overall Mac positioning.

Compatibility winner: CalDigit TS4. It supports more operating systems and older Thunderbolt systems.

Price and Value

The CalDigit TS4 has an MSRP of $379.99. The Anker Prime TB5 is $399.99. A $20 gap is not huge, but the value math favors the CalDigit unless you specifically need Thunderbolt 5.

For less money, the TS4 gives you more ports, better card readers, broader OS support, Thunderbolt 3 compatibility, and a higher 9.2 review score. It is also a proven premium dock rather than an early-adopter purchase.

The Anker Prime TB5 makes sense when the 80 Gbps link, two downstream Thunderbolt 5 ports, 140W charging, or high-end display paths are the reason you are buying. If your laptop only has Thunderbolt 4, much of the Anker’s advantage disappears, while the price remains premium.

Value winner: CalDigit TS4. The Anker is compelling for a narrower audience, but the TS4 delivers more reliable value for most buyers.

Verdict: CalDigit TS4 Wins for Most Buyers

The CalDigit TS4 wins this comparison because it is the more complete and more broadly compatible dock. Its 18-port layout, UHS-II card readers, 2.5GbE networking, 98W charging, no-driver setup, and strong Mac support make it the better all-around recommendation in 2026. The 9.2 score vs the Anker Prime TB5’s 8.2 score reflects that practical advantage.

The Anker Prime TB5 is not a bad dock. It is powerful, modern, and genuinely interesting for Thunderbolt 5 laptops. But it is expensive, does not support Thunderbolt 3 laptops, has weaker card readers than the TS4, and depends heavily on host support for its best display tricks.

Choose the CalDigit TS4 if:

• You want the best all-around Thunderbolt dock for Mac or Windows
• You need more ports for storage, USB accessories, audio, and card readers
• You want UHS-II SD and microSD readers
• You use a Thunderbolt 3 or Thunderbolt 4 laptop
• You care more about proven reliability than early Thunderbolt 5 bandwidth
• You want the better value at MSRP

Choose the Anker Prime TB5 if:

• You already own a Thunderbolt 5 laptop
• You need 140W host charging
• You use Thunderbolt 5 storage or displays that benefit from 80 Gbps bandwidth
• You want HDMI 2.1 and DisplayPort 2.1 built in
• You are comfortable checking host-specific display support before buying
• You plan to upgrade your laptop soon and want a more future-facing dock
