We Finally Get To Try Out The Gigabyte Brix Pro

We first saw the Gigabyte Brix Pro Ultra Compact PC Kit in September 2013 at the Intel Developer Forum and instantly fell in love with the pint-sized system due to the hardware inside. Gigabyte managed to fit the Intel Core i7-4770R 3.9GHz quad-core processor  along with Intel’s powerful new Iris Pro 5200 integrated graphics in a form factor that is just 62 x 111.4 x 114.4 mm or 0.79 Liters in size. We recently got our hands on the Gigabyte Brix Pro GB-BXi7-4770R, which is the flagship model that runs $649.99 plus shipping if you are lucky and can find a retailer that isn’t out of stock at the moment. The Gigabyte Brix Pro is only available in limited regions and only available in black and red with the Intel Core i7 4770R processor. It should be noted that the $650 price tag includes the DIY PC kit that includes the Brix Pro, 802.11ac mini PCIe wireless card and the power adapter and cable. You still need to purchase a dual-channel DDR3L SO-DIMM memory kit and the mSATA Solid-State Drive and/or a 2.5″ drive, which will add to the price of this build.

Gigabyte Brix Pro Ultra Compact PC

We’ll be taking a look at the Gigabyte Brix Pro GB-BXi7-4770R in black today. This PC features a 4th Generation Intel Core i7-4770R ‘Haswell’ processor that runs at 3.2GHz (3.9GHz Turbo) and Intel Iris Pro 5200 graphics. This is the very best of the integrated graphics solution that Intel has to offer and is the same one used in some of the high-dollar Apple 2013 iMacs. This is a system that is aimed at high-end users that want a powerful CPU and graphics capable of playing some games and running a 4K or mufti-monitor setup.

Gigabyte Brix Pro GB-BXi7-4770R Features:

  • Intel 4th generation Core i7-4770R processor
  • Intel Iris Pro graphics 5200 w/ 128MB of EDRAM or embedded ram
  • Supports 2.5” thickness 7.0/9.5mm Hard Drives (1 x 6Gbps SATA3)
  • Ultra compact PC design – 0.79L (62 x 111.4 x 114.4 mm)
  • 1 x mSATA SSD Slot
  • 2 x SO-DIMM DDR3L Slots (1333 / 1600 MHz)
  • IEEE 802.11 a/b/g/n/ac Wi-Fi / Bluetooth 4.0 Mini-PCIe card
  • HDMI plus Mini DisplayPort Outputs (supports dual displays)
  • 4K resolution output (4096 x 2304 via HDMI)
  • 4 x USB 3.0
  • Gigabit LAN
  • Headphone jack with S/PDIF
  • VESA mounting bracket (75 x 75mm + 100 x 100mm)


Inside the retail packaging you’ll find the BRIX Pro, power adapter, power cord, VESA mounting plate, screws for the mounting plate and VESA bracket and then finally the instructions and a driver disc. I’m not sure why any company bothers to ship driver discs in this day and age, but you have a copy of the already outdated drivers on it!

Gigabyte Brix Pro

On the top of the Gigabyte Brix Pro you have a power button with an activity/status light built-in. It should be noted that the glossy black surface horribly shows fingerprints, so have your cleaning cloth ready if fingerprints bother you. On the front panel you have a pair of SuperSpeed USB 3.0 ports and for audio connectivity there is a SPDIF audio a front panel connector. This will be useful in Home Theater scenarios that use an A/V receiver. A good portion of the front housing is a mesh cover for improved airflow and on the side of the Brix Pro there are also ventilation slots.

Gigabyte Brix Pro Back

On the back of the Gigabyte BRIX Pro you’ll find both Mini DisplayPort and HDMI ports on the rear panel, enabling support for simultaneous dual display connectivity. The GIGABYTE BRIX Pro also supports the latest 4K displays by offering support of screen resolutions of up to 4096 x 2304 via HDMI. You also have a Kensington Security Slot, DC power in, Realtek Gigabit LAN and another pair of USB 3.0 ports. The hot exhaust air from the CPU cooler is blown out of the large ventilation hole above the rear input/output ports and there are more vents and slots for cool air to enter on the side of the case and below the rear I/O panel. Cooling the mighty Intel Core i7 4770R processor is going to be a chore as this high-end chip is rated as being a 65W part under typical load scenarios, but can reach around 85 Watts under extreme load situations. Gigabyte is going to need a beefy cooler with a high CFM fan to keep this temperature running cool. In the past that has meant you’ll end up with a noisy system, but we’ll see if Gigabyte came up with a good solution.


The power adapter that is included with the Giabyte Brix Pro is a 135W model with a DC19V output (7.1A) made by FSP Group. The exact model number is FSP135-RSEBN2 and we’ve run across this power adapter before on All-In-One (AIO) systems and tiny PCs. This power brick has a power efficiency level rating of V, which means it has to be 86% efficient at low voltage and 87% efficient at standard voltages. It also must have a true power factor of 0.9 or greater at 100% of rated load when tested at 115 volts @ 60Hz. This power brick does have a noticeable whine to it and can be heard in a quiet room especially at low loads.


We’ve covered the basics of the Gigabyte Brix Pro, but before we get to benchmarking and performance testing, let’s first take a look at the inside of the DIY PC kit and show you how we built ours.

    I was finding a review for this, great one

  • Kevin Hess

    complete junk

    • Todd Oxenford

      “Complete junk.”

      I think not! I use this as my Plex Media Server and it does a fine job transcoding multiple streams at once with no issues.

      • vampyren

        Good to hear 😀
        I have a NUC with i5-4250U and it sucks, cant even play the movies locally with Plex. So i was looking at this. Nice to hear your happy with it. Sure its expensive but i watch movies allot and love Plex for keeping a nice library 😀

        • Todd Oxenford

          I think you really need an i7 for transcoding. As I said, I have multiple streams running locally and remotely and have no issues..although, it does get loud, so I put the everything inside a cabinet and am using a Logitech Harmony Hub, controlling everything with an old iPad.

          It’s worth the upgrade. I also bought one for my son who needed an new PC, and he mounted it on the back of his LED TV.

    Hey Legitreviews/Nathan. Thanks for a good review! 🙂
    This review was very interresting to read but it would have been even better if you could have demonstrated game performance with different RAM speeds, and also if you could have shown more reference systems and a few more games because right now its a bit hard to evaluate how much better this performs compared to say a desktop Intel HD 4600, or where it would place compared to a GTX650/750.
    Btw, I really agree with you they should have made it one/half inch taller for better cooling. I actually would have preffered a overdimensioned cooler by big margin rather than this underdimensioned one that encourages ppl to underclock their new system.

    PS. Maybe the reason the TDP went skyhigh was because the memory was much faster than i7-4570R’s max specced RAM-speed (=1600mhz). Anyway still a really interresting aspect of this Brix Pro and before reading this review I didnt knew it would accept that kind of “OC”. I hope gaming-performance scales linearly with RAM speed.

    what is this good for?

    Kind regards

  • Felipe

    Is it possible to have both SSD and a 2.5 HDD at the same time?

    • Simon

      Yes, mSATA + 2.5″ SATA HDD (9mm)

  • Sin Sentido Comun

    WOuld be nice to test audio software, I am very interested but noise can an issue, at the same time audio apps doesn’t consume much video power (or not one at all) so it might not push the GPU too much,

    • Todd Oxenford

      I run Foobar for some ripped SACD’s and it works and sounds great going through Dolby Digital 5.1.

    Any chance you have a Kinect for Windows sensor and are willing to try out the system compared to something like a GTX 680? If that thing can get solid 30fps in 3d mapping mode, it will be THE robotics controller platform everyone is using.

    • legitreviews

      I do not have the Kinect for windows sensor and I know that has different features than the normal Xbox 360 Connect that are all over. Anyway to use the Xbox version?

      • basroil

        There’s nothing technically stopping you if you have the USB adapter, though the results might get wonky. Kinect Fusion doesn’t inherently use any of the Kinect for Windows features unless you enable them, so as long as you don’t try texture mapping or near mode it should work. Just remember to up the resolution (voxel density) until you hit just under 2gb vram use.

        • Peter

          Did you have the time to try Brix with the kinect sensor?

        • basroil

          Still no budget for brix, perhaps in another 6mo (though 960m version would be out by then)

  • Internet

    Why do you mention BIOS repeatedly in the review? This is a UEFI implemntation, not a BIOS. But you call it “UEFI BIOS” to really get things wrong. Why?

    • Internet

      Perhaps you can merge this in with the previous note?

      Watts dissipated in use isn’t “TDP” – TDP is Thermal Design Power. You can’t “hit a TDP of 85w” during use; the design power is still 65W. You are instead generating 85w in the form of heat, but not generating a “TDP.”

      I won’t go in depth about the editorial problems with this piece… nearly every page has some flaw, including missing half of a paragraph on page 3.

      Also: Your KeyShot 4.3 is unregistered, and not for commerical use. But the purpose of these reviews is ad revenue, isn’t it?

      I don’t really get what’s legit about repeated misuse of terminology.
      This article is quite poorly written and I do not believe the author possesses
      the knowledge necessary to write about these topics.
