Zotac has made a name for itself over the years by packing copious amounts of computing power into ever-shrinking form factors. We were impressed with the Zbox Magnus EN1070 and have an even-faster Zbox Magnus EN1080K in the TR labs right now. The company is back at it again with two new machines. The Zbox PI225 has enough performance for everyday tasks, and it's stuffed into a fanless package roughly the size of a SATA SSD. Meanwhile, the Zbox MI553 brings an Intel Core i5-7300HQ quad-core processor and next-generation display and peripheral connectivity to the party.
The Zbox PI225 is built around Intel's Apollo Lake Celeron N3350 dual-core SoC. The 1.1 GHz CPU base clock isn't going to knock socks off, but the little chip can Turbo up to 2.4GHz when called upon. The PI225 can go without a fan thanks to the processor's power rating of just 4 W. The CPU is partnered with 4 GB of LPDDR3 memory. A 32 GB eMMC chip provides primary storage and a microSD slot allows expandability. The 64-bit version of Windows 10 comes pre-installed.
The outside of the box sports a pair of USB 3.0 Type-C ports and a microUSB power jack. One of the USB Type-C connectors must be used for display output using the included Type-C-to-HDMI adapter. The maximum display resolution is 4096x2160 at 30 Hz. The tiny machine has 802.11ac Wi-Fi and Bluetooth 4.2 support for connecting to wireless networks and peripherals. The box measures a mere 3.8" long, 2.5" wide, and just 0.3" thick (9.5 cm x 6.3 cm x 0.8 cm). Those measurements are just a bit larger than a standard Raspberry Pi's 3.4" x 2.2" (8.6 cm x 5.6 cm) footprint, and that's not counting the Pi's enclosure.
Folks willing to tote around a larger package in exchange for more horsepower might want to look at the Zbox MI553. The mobile Core i5-7300HQ processor can boost up to 3.5 GHz and sports Intel's HD 630 graphics with full H.265 decoding support and the ability to stream Netflix at 4K resolution. Zotac offers a turnkey version of this machine with 4 GB of DDR4 memory and a 120 GB M.2 SATA SSD preinstalled. Pickier gerbils might prefer the barebones version with two empty DDR4 SODIMM slots, an M.2 2242 SATA slot, an M.2 2280 PCIe slot, and a spot for a 2.5" SATA drive.
The Zbox MI553 connects to monitors using DisplayPort 1.2 and HDMI 2.0 outputs. Those jacks on the back of the box are joined by a Thunderbolt 3 port, four USB 3.0 connectors, a Gigabit Ethernet jack, and a connector for an external Wi-Fi antenna. The front panel has a USB 3.1 Type-C port, audio jacks, and a card reader. Like its smaller brother, this machine has 802.11ac Wi-Fi and Bluetooth 4.2 support. External dimensions measure 7.3" on each side and 2.8" tall (18.5 cm x 18.5 cm x 7.2 cm).
