Ulefone Atom 3 and Atom 4 Mini PCs Launched: Prices, Features and Key Differences

A desktop PC does not have to take up half your table. The new Ulefone Atom 3 and Atom 4 pack a Windows computer into a small box that can sit beside a monitor or hide behind it. Both come with 16GB RAM, a 512GB SSD and Windows 11 Pro, but their display support, storage expansion and size are quite different.

Ulefone is expanding beyond rugged phones with this new mini PC series. The Atom 3 focuses on connecting more screens and peripherals, while the Atom 4 is the smaller, lower-priced option for a simple desk setup. These are launch details, not a hands-on performance review.

Ulefone Atom 3 and Atom 4 Prices

The Atom 3 launch price is US$489.99, against a stated regular price of US$549.99. The Atom 4 launch price is US$389.99, against a stated regular price of US$449.99. That puts a US$100 gap between the two launch offers.

Sales began on 11 November 2026 through the Ulefone Official Store, AliExpress and OZON. The launch offers run through 11 December 2026. These are global dollar prices, not Indian retail prices. Ulefone has not announced an India-specific price or local retail launch in this announcement.

Atom 3: More Screens and Storage

The Atom 3 uses an AMD Ryzen 3 7330U processor with four cores, eight threads and a boost clock of up to 4.3GHz. It is positioned for office work, study, browsing and everyday multitasking. Those specifications alone do not establish how it will perform under sustained heavy workloads.

Its more useful distinction is the ability to connect three 4K displays at 60Hz. HDMI, DisplayPort and the full-featured USB-C port provide the three outputs. A spreadsheet on one screen, a browser on another and a video call on a third is the kind of workflow this arrangement can help organise.

Storage expansion is another advantage. The Atom 3 has two M.2 2280 SSD slots, with support for up to 2TB per slot, or 4TB in total. The supplied SSD is 512GB; extra drives are not included. This gives it room to grow if documents, photos or project files start filling the original drive.

Atom 4: A Smaller Desktop Setup

The Atom 4 takes a different approach. Its body measures 100.6 × 100.6 × 34mm and weighs approximately 265g. That makes the computer itself easy to move between workspaces, although it still needs mains power, a screen and input devices. It is not a laptop replacement for use away from a desk.

Inside is an AMD Ryzen 5 3501U with four cores, eight threads, a boost clock of up to 3.7GHz and Radeon Vega 8 graphics. The Atom 4 supports two 4K displays at 60Hz. Its model number and Ryzen 5 badge should not be read as proof that it is faster than the Atom 3; the two use different processors and need real testing for a fair performance comparison.

Ulefone claims cooling noise as low as 21dB. This is a company figure, not a measured result from our testing, and should not be taken to mean the fan will stay equally quiet under every workload.

The Atom 4 ships with a 512GB M.2 SSD. Its official specifications allow that drive to be replaced with one of up to 2TB. Unlike the Atom 3’s two-drive arrangement, this is a replacement upgrade rather than adding a second SSD.

Ports, Wireless Connectivity and Displays

The Atom 3 offers seven USB ports: one 10Gbps USB-C, two 10Gbps USB-A ports and four 5Gbps USB-A ports. There is also Gigabit Ethernet, Wi-Fi 6 and Bluetooth 5.2. This gives it more flexibility for a keyboard, mouse, webcam, external storage and other desk accessories.

The Atom 4 is simpler, with two USB-A 3.0 and two USB-A 2.0 ports, alongside Gigabit Ethernet, Wi-Fi 5 and Bluetooth 4.2. Its HDMI and DisplayPort outputs handle the two-screen arrangement. Both machines have a 3.5mm audio connection.

The 4K figures describe display output, not a promise of 4K gaming performance. These compact systems are better understood as everyday desktop options rather than dedicated gaming machines.

Windows 11 Pro and VESA Mounting

Both models arrive with Windows 11 Pro pre-installed and include a VESA mounting bracket. Mounting the computer behind a compatible monitor can free up desk space and keep the main box out of sight. You will still need to plan the power, display and accessory cables.

A mini PC can be useful when a monitor, keyboard and mouse are already available. It avoids replacing the entire setup just to change the computer. Ulefone also positions these models for classrooms, retail counters and digital signage, though suitability will depend on the software and connections needed.

Which Atom Mini PC Makes More Sense?

On the announced specifications, the Atom 3 is the more flexible choice for a multi-screen desk. Its third display output, extra USB ports, newer wireless connectivity and two SSD slots explain much of its higher price.

The Atom 4 prioritises compact size and a lower entry price. A two-monitor office setup that does not need many fast USB devices may fit its feature set. The decision should centre on those practical differences rather than the model numbers alone.
