Apple recently unveiled a new lineup of Macs, all powered by the next-generation M4 chips that deliver enhanced performance and efficiency. These models come equipped with either the M4, M4 Pro, or M4 Max chips. While the M4 powers the base models, the M4 Pro and M4 Max provide additional horsepower and incorporate advanced technologies like Thunderbolt 5, a high-speed data transfer protocol co-developed by Intel and Apple.
If you’re considering an M4 Pro-powered Mac Mini or an M4 Pro/Max-powered MacBook Pro, these models mark Apple’s first computers to feature Thunderbolt 5. Some Intel-powered laptops, such as the Razer Blade 18, also offer Thunderbolt 5 compatibility.
Thunderbolt 5 represents a significant leap in data transfer capabilities, supporting speeds up to 80 Gbps and up to 120 Gbps with the Bandwidth Boost feature, making it up to thrice as fast as Thunderbolt 4, which peaks at 40 Gbps. This allows for connections to high-resolution (up to 8K) high-refresh-rate monitors using a single USB-C port, though a Thunderbolt 5-compliant data cable is necessary.
Introduced in September 2023, Thunderbolt 5 is now available in Apple’s latest Macs, making them among the first commercial devices to support this technology.
With Thunderbolt 5, a device like the Mac Mini M4 can achieve up to 80 Gbps of bi-directional data transfer, meaning it can send and receive data at that speed simultaneously. This feature is perfect for high-resolution displays and enables rapid transfer of large files, such as 4K and 8K video footage.
A single Thunderbolt 5 port can power up to three 4K monitors at 144Hz or two 8K monitors, while also supporting connectivity to a wide array of accessories like monitors, external GPUs, storage drives, and more through a single connection. However, Apple Silicon currently does not support external graphics, limiting this feature to Intel-powered Thunderbolt 5 PCs.
A major benefit of Thunderbolt 5 is that it utilizes a standard USB-C port. To maximize the potential of Thunderbolt 5, you’ll need a certified Thunderbolt 5 USB-C cable, which is priced slightly higher than a regular USB-C cable.
Thunderbolt 5 is also backwards-compatible with Thunderbolt 4 and USB4 v2, so you can continue using existing accessories, albeit at Thunderbolt 4 speeds of 40 Gbps.
Thunderbolt 5 is available on all Macs with M4 Pro or M4 Max chips, including the latest Mac Mini, 14-inch MacBook Pro, and 16-inch MacBook Pro. For high-end Intel laptops with Thunderbolt 5, you’ll need to check the specifications, as only some models feature it.
