Gigabyte Brix GB-BXi7-4500

Seven Small (But Powerful) Mini-PCs, Reviewed

Gigabyte isn't the first company we think of when the conversation switches to small PCs, but the company is working hard to impress with its Brix product line. The goal appears to be to best Intel at its own game (even though we know that, in reality, both companies work closely together). The Brix is slightly smaller and significantly lighter than Intel's offering. Gigabyte further mixes things up with some interesting configuration options: the BXPi3-4010 features an integrated WVGA (864x480) projector, while the BXA8-5545 may be the closest thing to an AMD-based NUC, equipped with an A8-5545M APU with on-die Radeon 8510G graphics. We also have the Brix Pro in our lab, outfit with a Core i7-4770R that includes Iris Pro graphics 5200.

The model we're reviewing today is the BXi7-4500, featuring Intel's Haswell-based Core i7-4500U with 4 MB of shared L3 cache, a 1.8 GHz base clock rate, and a 3 GHz Turbo Boost ceiling. Somewhat disappointingly, the Core i7-4500U is equipped with HD Graphics 4400, rather than GT3/GT3e GPU. As a result, our expectations of graphics performance aren't very high.

The BXi7-4500 is currently available on Newegg for $530 as a barebones system. Adding Windows 8.1 Pro x64 OEM, Intel's SSD 525 180 GB, and 8 GB of Crucial DDR3 brings the price as tested to $954.98.

Bundle And First Impression

Bundled inside the box, you'll find the Brix mini-PC, a VESA mount, an AC adapter and power cable, documentation, and a driver CD. While Intel gives you the AC adapter with its NUC, you don't get a power cable (though in our meeting with Intel at CES this year, company representatives mentioned this is changing), so Gigabyte gets credit for its more complete kit. The VESA adapter plate is used to mount the Brix on a monitor, if you want it out of sight.

Gigabyte's styling looks a lot like Intel's design, with the added flair of a silver accent around the Brix's top edge. At 1.2" x 4.2" x 4.5" and 0.8 lbs, this is the smallest and lightest mini-PC in our round-up. In fact, it's only about 75% as heavy as the previous-gen Ivy Bridge-based NUC. 

The front of this Brix is kept fairly simple; there are two USB 3.0 ports, and a combo headphone and S/PDIF jack. You can also see the power button up top.

Around back, there's an AC power connector, HDMI output, mini-DP output, GbE jack, and two more USB 3.0 ports.

This is the bottom of the Brix. See the nub in the upper right-hand corner? That little handle makes it easier to pull off the bottom cover compared to Intel's NUC.

If it wasn't for the blue Gigabyte motherboard, you might assume you were looking inside Intel's mini-PC. The basic configuration is the same: there are two SO-DIMM slots for dual-channel DDR3 configurations, a mini-PCIe slot on the opposite end of the board, with an mSATA slot next to it. Although this is a barebones kit that requires memory and a hard drive, Gigabyte does give you a Wi-Fi/Bluetooth combo card. We're a little disappointed that it's a Realtek RTL8723AE-based controller limited to the 802.11n standard instead of ac, but at least Bluetooth 4.0 is supported.

Note that platforms based on mobile Haswell only support 1.35 V SO-DIMMs; your older 1.5 V DDR3 modules won't work. Check out Haswell And 1.35 V Memory: Three DDR3 SO-DIMM Kits, Tested for more information on performance at each data rate with Intel's newest architecture.

Special Features And Livability

It seems like Gigabyte's Brix is the company's attempt to improve on Intel's NUC while making it even smaller. Although the company's design tweaks are evident, they aren't particularly impactful, either. Having said that, the inclusion of a power cable, a bundled Wi-Fi/Bluetooth adapter, and the bottom cover handle earn the Brix favor, all else being equal. They're not, though. The $530 BXi7-4500 is more expensive than Intel's $375 Haswell-based NUC D54250WYK on Newegg. The BXi5-4200 at $390 is a closer match, though. Comparing those two sub-$400 competitors, the Brix has a higher base clock, while the NUC gives you HD Graphics 5000 (making gaming a much more viable possibility). Regardless of your choice, the match-up is much closer.
