UniFi Cloud Gateway Ultra vs Max: $150 Apart

These two are the closest pair among the eight gateways this site tracks, sharing a quad-core A53 at 1.5 GHz, 3 GB of memory, the same 141.8 × 127.6 × 30 mm case, and the same 0.96-inch status display. Ubiquiti even rates them identically for scale, at 30+ UniFi devices and 300+ simultaneous users.

What separates them is the speed of everything downstream of the WAN port and whether the gateway can hold footage. If neither is a constraint, the cheaper unit is the whole answer. How to choose a UniFi gateway sets both against the rest of the range.

Both accept a multi-gig line, because both WAN ports run at 2.5 GbE. The difference begins one hop later. The Ultra hands that traffic to gigabit ports and the Max does not, so a 2 Gbps plan reaches a single device on the Max and never does on the Ultra.

This matters more over time than it reads. A switch, a NAS, or a Wi-Fi 7 access point on a 2.5 GbE uplink is held to a gigabit behind the Ultra. That is the port most people wish they had bought differently. UniFi uplinks and aggregation covers where 2.5 GbE at the edge pays off.

For a household on gigabit fibre with gigabit devices, none of this is reachable, and the Ultra's four ports are simply four ports.

IDS/IPS throughput is the ceiling that applies once threat inspection is switched on, and the Ultra's sits exactly where a symmetrical gigabit line does. That is comfortable today and has no headroom if the line is upgraded, which is the argument for the Max even on a network that is otherwise gigabit.

A common misreading is that the Ultra's 2.5 GbE WAN port implies 2.5 Gbps of inspected throughput. The port speed and the inspection rating are separate figures, and it is the smaller one that governs once IPS is on.

For anyone planning Protect cameras, this line usually settles the comparison on its own, because the alternative behind an Ultra is a second box — an NVR or a gateway that can hold a drive. Protect storage sizing works through how much disk a given camera count needs.

The drive is a separate purchase on the Max, so the real figure is $279 plus an SSD. Even so, it is one device on the shelf rather than two, and the camera count it supports covers most homes.

Both are fanless and both run from a USB-C supply, so this is a difference in what the adapter has to deliver rather than in how the unit behaves. Neither will be the thing that shows up on an electricity bill.

Weight runs the other way, which is a small surprise. The Ultra is 520 g and the Max 460 g without an SSD, rising to 519 g with one fitted. Both share the same case dimensions and the same -10 to 40 °C operating range.

The device ratings are identical, so this is a question about port speed, line speed, and cameras.

Buy the Cloud Gateway Max if:

• Your network is 2.5 GbE, or heading there. Four 2.5 GbE LAN ports are the reason to spend the $150.
• Your line is faster than a gigabit. 2.3 Gbps of IPS leaves room where the Ultra's 1 Gbps does not.
• Cameras are coming. The NVMe slot makes it a recorder; the Ultra cannot be one.

Buy the Cloud Gateway Ultra if:

• Gigabit is the line and the devices. Nothing above is reachable, and $150 buys a lot of other hardware.
• Draw matters. At 6.2 W it is the lightest load of the eight gateways here.
• A separate recorder is already planned. An NVR or a rack gateway makes the Max's slot redundant.
