Seven Small (But Powerful) Mini-PCs, Reviewed

Intel NUC D54250WYK (Haswell)

While the previous-gen NUC was limited to a 1.8 GHz Core i3, the Haswell-based models can be quite a bit quicker. The D54250WYK comes with a Core i5-4250U operating at 1.3 GHz. It spins up to 2.6 GHz under the right thermal conditions thanks to Turbo Boost, though. More important, it features Intel's HD Graphics 5000, yielding a big step up in mainstream gaming potential.

Newegg has the model listed for $375, though it's currently not in stock. Amazon does have the NUC available, albeit priced in excess of $400. And again, this is a barebones kit, so you still need memory, a Wi-Fi module, and an mSATA-based SSD. Adding Windows 8.1 Professional, Intel's SSD 525 180 GB, and 8 GB of DDR3 from Corair raises the total to $833.97, which is more than twice what you pay for the kit.

Bundle And First Impression

You would think that Intel received enough feedback from its NUC launch a year ago to start bundling a power cable. We talked to the company at CES 2014, and it does in fact plan to start including a cable. But the Haswell-based unit we have for review still doesn't come with one. For now, that cable you see in the picture above has to be purchased separately. The barebones kit comes with an AC adapter, a VESA mounting plate, documentation and, of course, the NUC, though.

I can't imagine anyone complaining about the size of Intel's first effort. It immediately impressed us with compact dimensions and very capable internals. However, Intel took about 15% of the D54250WYK's height compared to the Ivy Bridge-based models. At 4.6" x 4.4" x 1.4" and 1.05 lbs, the weight is down a bit as well. The metal sides are no longer the same color as the top; now they're silver. But the basic design remains the same. At the end of the day, it looks like Intel took a bit of direction from Zotac's Zbox Nano.

The front of the newer NUC sports more connectivity than last generation's. It offers two USB 3.0 ports, a combo input/output audio jack, and an IR sensor for your media center remote (purchased separately).

Around back you find the power connection, mini-DP output, a mini-HDMI interface, GbE networking, and two more USB 3.0 ports.

The interior looks a lot like the previous-gen NUC, except for the addition of SATA and the same as the original NUC with the addition of a SATA port that can't really be used anyway due to this unit's enclosure. By building it onto the motherboard, though, Intel paves the way for slightly taller configurations with room for a 2.5" hard drive or SSD. You still get two SO-DIMM memory slots on one side of the board and two mini-PCIe interfaces (one with mSATA drive support) on the other.

Once again, we know that Haswell-based mobile processors don't work with 1.5 V DDR3 memory. You need to make sure you seek out 1.35 V DDR3L to use with this platform.

Special Features And Livability

The D54250WYK is an evolved NUC. It's smaller than its predecessor with more functionality. Intel's prior effort lacked audio I/O, so that was added. The IR sensor is new too. We find a lot more ports to accommodate external peripherals. Without question, the new NUC is much more desirable than the Ivy Bridge-based version.

    Not a single AMD based SFF PC?
    I am disappoint, this would be a great area for AMD to show their competitiveness.
  • ta152h
    @outlw6669I built one based on the A6 5200, and it's perfect for what I need it for. It's low power, more than fast enough for what 99% of the people do, quiet, and inexpensive. I'm a little surprised they didn't choose something based on the Jaguar for that reason, but it might just be a situation where nothing with one was sent to them for review. Certainly this is a poor representation, without both Jaguar and Bay Trail missing. I got to the first page, read what they had, looked at the cases, and moved on. Reading about different versions of Ivy Bridge and Haswell and how they compare to each other is profoundly uninteresting.

    I wouldn't mind having a small system like this. Maybe Mid-Year when everyone's CPU/APUs are out, I'll have the chance to make a smart buy. Thanks for the article. :)
  • blackmagnum
    Buy a laptop and hook a screen to it; no compromises.
  • mesab66
    It is interesting that by going slightly larger with the enclosure space (still keeping within cube/rectangle/media player shape) opens up the possibility of so much more power....dedicated gfx, full cpu, etc etc., and, can be cheaper to build - depending on the users requirements.......of course, at the cost of power requirements, etc. I'm thinking most folk would ideally chose a slightly larger form factor for living room/media pc duties.On the other hand, if constraints are tight (form factor in this article) and the end user's requirements match, then these options are worth considering.
  • mesab66
    Maybe Tom's could do some options on Media PC/HTPC builds for a future article?

    Power. I don't care about no power. Where's the love for the old games? If I want to play some of the classics which just don't emulate properly, I have to hunt for a heavy old Pentium3 box and try to get it working. How about a cheap mini PC with miniaturized legacy hardware for full compatibility to dual-boot win98 & XP, with gameports, VGA & S-Video, PS/2 & USB, IDE & SATA external ribbon & power connectors, & a turbo button for choosing between 2 processors 200MHz & 3GHz?

    I am a huge fan of compact systems. Almost everything I have built has been ITX. But I've had a hard time with the NUC form factor. As a desktop, I think it's actually too small. One of those boxes would get lost on my desk, continuously being pushed around by other clutter. Now, if I had a hutch with an optimally sized cubby, that might be a different story.

    VESA mounted on the back of a monitor, these look really clunky, and I'd rather go with an AIO kit using the thin mini-ITX form factor where I have more control over processor choice.

    I'd be more excited if this technology and form factor were applied in a more interchangeable system with a standardized GPU socket. I really like what ASRock and Gigabyte have done with their compact systems. They're not as compact, but having something a little more substantial on my desk is a good thing, and they pack a lot of punch. I just wish the standards were developed to allow builders to replicate that feat - pipe dream, I know.

    One thing is for sure, AMD needs to develop it's own equivalent of the NUC and thin Mini-ITX. The success of it's Kaveri line I think would be helped out by innovation in form factor.
  • axehead15
    I think you should compare the Mac Mini to these, that way we can see how it adds up.
  • Onus
    It would take a unique set of requirements for any of these devices to make sense, particularly compared to competition. With the possible exception of the ASRock unit, the price is outrageous. If you don't have room by your TV for a [much more powerful and versatile] mini-ITX system, for the difference in cost you can replace your TV stand or component rack instead.

    These are essentially for gadget-freaks with more money than sense.
  • bloodroses75
    Interesting concept for these machines, price to performance is not worth it yet though. Buying an Inwin (or other brand) mini-itx case with power supply and building your own machine from the ground up is a much better deal.As with Intel, the i7s are only dual core? I'd be personally upset if I bought one and realized that after plugging it in. They should have kept a standard with their naming, like on their desktops:Pentium= dual core, no HTi3= dual core, HTi5= quad core, no HTi7= quad core, HTand yes, I realize Intel did release an i5 that was only dual core with HT and thought it was a complete rip-off too.

    Why did people vote down s997863? I'd kill for a mini pc that could actually play NWN 1 and/or the horde of DOS games.

    I'm pretty sure any of these will fit the bill for old windows games like NWN 1.

    DOS based stuff has its own challenges, I don't know enough about dosbox emulators but I suspect these are more than powerful enough.
  • Bolts Romano
    Thank you for the article, at least now I know some other brands never heard before. It is quite a surprise the price is hitting the same level as a notebook or mac mini price range or lower (remember this mini pc does not come w OS)
  • burkhartmj
    these devices are super cool, but it's hard to ignore the fact that one can generally get better performance out of a fully configurable and upgradable ITX form factor for the same price. For niche use cases, these would be incredibly helpful, but I don't see them becoming particularly mainstream.

    On the contrary, there are plenty of performance issues with old games when using new hardware. My 6670 and 7850 play NWN 1 piss-poorly with my 965 BE, por ejemplo.

    Intel's IGPUs fare no better nor do NVidia's GPUs. Speaking from experience.

    Why some i7 are dual cores?
  • Croc Ography
    Huge fail for the ASRock... Tom's Hardware is not reading their own listed specs:"Audio Channels: 7.1+2 Channel HD Audio Codec with Content Protection and DTS Connect support" -- this means that if you burn your own Blurays or DVD's to PLEX or BMC and any of them have Cinavia on them you will not be able to play them from this HTPC.Therefore this device is useless.
  • tntom
    Great article! Thank you! Thank you! I hope this segment becomes more competitive and brings the prices down. Right now the prices are too inflated. All of these have more than enough CPU but except for the Asrock are lacking in GPU performance.Please update with the Brix A8 APU and Iris Pro 5200 when you finish testing them out.
