Razer Thunderbolt 5 Dock Chroma REVIEW Next-Level Docking for Mac and Windows Power Users

Upgrade your workstation with blazing-fast performance, expanded display support, and integrated SSD storage in one sleek, RGB-lit hub.

I’ve been patiently waiting for the Razer Thunderbolt 5 Dock to be released for months now. I’ve had the Thunderbolt 4 Dock Chroma for a few years and was very excited when I learned the next generation was being released. The Thunderbolt 4 Dock has been a reliable piece of my workstation, but as my technology has advanced to include Thunderbolt 5 connectivity, I want to take full advantage of what TB5 has to offer.

As of writing this article, Thunderbolt 5 in Windows laptops is limited. There are very few gaming laptops that support it and the ones that do have starting prices of approximately $2,000. That said, Thunderbolt 5 is fully supported in the latest iteration of macOS laptops. With that in mind, I tested the dock with two MacBook Pros and two Windows gaming laptops as well as a gaming desktop as I was putting the dock through its paces.

Differences Between Previous and Current Version

Pricing & Availability

The Thunderbolt 5 Dock Chroma is being offered for $399.99 from razer.com. It is available in two color ways — Black and Mercury White.

User Experience

So, before I even unboxed the TB5 dock, I was excited because it has been updated to support 140W power delivery for host devices AND can support up to three 4K monitors at 144Hz each. Not only that, but all the ports are located in the back of the dock. This was super refreshing to me since cable organization is a big deal for me. All the other docks I’ve worked with seem to have at least one port on the front, which is infuriating to me because it causes a cable to be strewn across your desktop. And, when you have a dock as visually pleasing as the Razer dock, you don’t want to hide the glorious RGB light effects behind a cable.

When you open the box, you’ll find the dock sitting on top of the inner carton packaging, which houses the power cable, power adapter, Thunderbolt 5 cable, stickers, and a user guide. I’m always shocked at how large power adapter bricks are in relation to the dock, but the TB5 dock’s power adapter is almost larger than the dock. The dock is only about a half an inch longer than the brick, but the brick is wider than the dock by about a quarter of an inch. I really hope that there is a way to shrink these power bricks in the future. It’s one of the only shortcomings of using a dock like this.

One of the things I was most excited about with this dock was the fact that it’s actually listed as being compatible with macOS. Not too long ago, Razer finally released a version of Synapse for macOS and even though it’s still in the ‘preview’ phase, I’ve loved using it with my mouses and now the TB5 dock.

Getting everything connected was easy. I turned it on its end so that the back was visible and then moved accessories over from my other dock — one by one. If you have a lot of peripherals like I do, you might have a little difficulty getting everything connected. I have the following items I need to connect.

• Razer Deathadder v4 Pro Mouse dongle (USB-A)
• Razer DeathStalker v2 Pro keyboard (USB-C)
• Kensington W1050 Camera (USB-A)
• BenQ Screenbar (USB-A)
• ViewSonic Monitor (DisplayPort)
• Razer Basilisk v3 Pro mouse 2.4Ghz dongle (USB-A)

As you might have noticed, I have quite a few USB-A connected devices and while I don’t need two mouses connected at once, I like to leave the dongle for the Basilisk connected for when I do want to use it. Even though this dock promotes the use of Thunderbolt, not having a DisplayPort or HDMI port is a little tricky to get around. DisplayPort/HDMI to USB-C cables do exist, but if you are trying to get the best possible refresh rate and resolution, you need to make sure you have the right HDMI or DisplayPort cable. So, this might require the purchase of a new cable because the only cable that comes with the Razer Thunderbolt 5 dock is the TB5 host cable. The cable is on the short side. This isn’t a bad thing, but it’s worth noting since workstation planning will have to be done carefully to accommodate the length.

The RGB lighting really adds a lot to the aesthetic of the dock. It’s bright and it glows along the bottom edges of the dock. Using Synapse, you can control the lighting effect and make modifications as needed. There are seven preset lighting effects to choose from.

Testing

I used two different MacBook Pros and a couple of different Windows computers to test the dock out.

• 14-inch, Nov 2024 Apple M4 MacBook Pro: 70W, Thunderbolt 5 (digital video output)
• 16-inch, 2023 Apple M2 Max MacBook Pro: 140W, Thunderbolt 4
• GIGABYTE Gaming A16: Intel Core i7-13620H, 1TB SSD, 32GB DDR5 RAM, GeForce RTX 5060, 165Hz refresh rate (on laptop display)
• Lenovo Legion 9 (16IRX9) Gaming Laptop
• HP Omen 45L GT22-3060 Gaming PC

Display Resolution / Refresh Rate

In order to get the best results for resolution and refresh rate, I connected the 14-inch MacBook Pro to our 45-inch LG UltraGear OLED 5K2K Gaming Monitor (LG 45GX950A-B). This monitor has a native resolution of 5120 × 2160 @ 165Hz (5K2K ultra-wide, 21:9) and it supports DisplayPort 1.4 with HDCP 2.3 and HDMI 2.1.

Because the 2024 MacBook Pro is the only laptop I used in testing that can drive the full resolution/refresh rate through Thunderbolt 5, I used it for testing. I was able to achieve the full resolution and refresh rate, which I confirmed through the macOS display settings report. I also used UFO Test to confirm the refresh performance.

The Legion 9 laptop supports 8K resolution to external monitors so I was also able to confirm the full 5K resolution to the monitor connected through the dock — but I had to use a special DisplayPort to USB-C cable that supported the proper monitor bandwidth. The Thunderbolt 4 connection from the laptop supports 5K, but it caps out the refresh rate around 60Hz. So, for gaming purposes, I used the DisplayPort to USB-C cable.

Even though the GIGABYTE laptop doesn’t support Thunderbolt 5, I was able to connect it and determine that it can achieve full resolution with the right connection, but it works best at 2K (3440 x 1440).

Power Delivery Rate / Cooling

The dock was able to power the laptops with no issues. As far as cooling goes, I did hear the fan kick on a couple of times while I was testing. I never noticed its temperature getting to high and it was always cool the touch. I verified the temperature periodically with a handheld infrared thermometer. It was never higher than 87º.

SSD Storage Speed

In order to test the SSD’s speed, I ran two benchmarking tests — Blackmagic Disk Speed Test and AJA System Test Lite.

Using Blackmagic Disk Speed Test with a 5GB stress file, the SSD achieved write speeds of 2,728 MB/s and read speeds of 3,070.2 MB/s. This tool is commonly used by video editors to simulate editing and playback conditions, especially for high-resolution formats like 4K and 6K video. The results suggest the dock handles demanding media tasks with ease, offering reliable transfer rates for editing, exporting, and large file management.

In addition, the AJA System Test Lite was run using a 16GB test file at 4K Red HD resolution with the ProRes HQ codec. This test, which is also widely used in video production environments, delivered write speeds of 2,567 MB/s and read speeds of 3,029 MB/s. These numbers are consistent with the Blackmagic results and highlight the dock’s ability to maintain sustained performance under continuous load, something essential for professional users working with large video files or streaming data in real-time.

Although the tested speeds fall short of the theoretical maximum throughput of the WD_BLACK SN850X, a PCIe Gen4 x4 SSD, which is rated for up to 7,000 MB/s—this is expected when operating through an external dock. The Thunderbolt 5 interface, even with its doubled bandwidth compared to Thunderbolt 4, still shares PCIe lanes and incurs overhead through dock controllers. That said, achieving over 3,000 MB/s read and 2,500 MB/s write speeds in an external dock is impressive, and these numbers place the Thunderbolt 5 Dock Chroma well above typical external SSD enclosures in terms of real-world performance.

The Razer Thunderbolt 5 Dock Chroma’s M.2 slot performs exceptionally well, offering fast and stable throughput suitable for high-end workflows including video editing, game storage, and large-scale data transfers. The dock’s active cooling and power delivery appear to support the drive consistently under stress, making it a standout feature for professionals who need internal-grade performance in an external dock.

The only downside to the SSD is that it mounts like a standard external hard drive so if you want to unplug from the dock, you have to eject the external drive first.

Thunderbolt Share

Because Thunderbolt Share requires two PCs with at least Thunderbolt 4 connectivity, I used the Lenovo Legion 9 and HP Omen computers to test out this feature. This is a new feature introduced with Thunderbolt 5 technology but it’s supported on Thunderbolt 4 as well. Both the aforementioned machines have a Thunderbolt 4 port so I was able to connect the two using the Intel Thunderbolt Share software. I connected the Legion laptop as the host computer and then used the HP Omen as the shared machine. I was able to very easily drag and drop files from one PC to the other. It was much faster than over WiFi. Thunderbolt Share also has a KVM function where you can use your peripherals with both machines that are connected via Thunderbolt Share. I didn’t have any issue with that feature either.

I was also able to test out Thunderbolt Bridge between the two MacBook Pros, which is a similar feature. It allows two Macs to connect via Thunderbolt and transfer files over a high-speed peer-to-peer network, but it doesn’t enable the KVM function.

To test out this feature I plugged the 2024 MacBook Pro into the dock as the host computer. Then, I plugged the 2023 MacBook Pro into the dock using a Thunderbolt 4 cable. Because of Thunderbolt Bridge, I was able to connect directly to the 2023 MBP and drop files to it. It was blazing fast and nearly instantaneous. Since I’m constantly switching between my personal and work laptops (the two laptops I used for testing)this file sharing option can come in very handy.

Conclusion

The Razer Thunderbolt 5 Dock Chroma delivers on its promise as a next-generation docking solution for users with cutting-edge devices. It builds meaningfully on the already-excellent Thunderbolt 4 Dock Chroma by doubling bandwidth, expanding display support, increasing power delivery, and introducing standout features like a PCIe Gen4 SSD slot and Thunderbolt Share. While Thunderbolt 5 is still in its early stages, particularly in the Windows ecosystem, macOS users with supported hardware can take immediate advantage of what this dock offers. From stable high-speed SSD performance to streamlined cable management and sleek RGB styling, this dock elevates the workstation experience.

For anyone who is looking for fast file transfer options and superior monitor connectivity for gaming, the Razer Thunderbolt 5 dock is the one to get. In my opinion, this is the gold standard for Thunderbolt 5 docks.
