Intel introduced a separate microarchitecture for low-power / low-cost x86 systems in the 2008 Silverthorne Atom processors. Variation of the microarchitecture in different product families has since helped the company to span a wider performance / power efficiency range. From 2008 to 2020, each product family opted for either the Atom-class microarchitecture or the Core-class one. However, the introduction of hybrid CPUs (starting with the short-lived Lakefield) saw the placement of cores based on both microarchitectures in the same die. The Tremont microarchitecture (developed as part of the Atom-family) made its debut in Lakefield before gaining wider market presence through Jasper Lake and Elkhart Lake. Its successor (Gracemont) is adopting a similar trajectory. After its introduction in Alder Lake (ADL), it underwent further refinement in Raptor Lake (RPL). The hybrid processors in these two families teamed up the Gracemont efficiency cores with the Golden Cove (ADL) / Raptor Cove (RPL) performance cores. Eventually, Intel released a new line of processors under the 'Alder Lake-N' (ADL-N) tag comprising only the Gracemont cores, a pared-down integrated GPU, and premium connectivity options removed. As a replacement for the Tremont-based Jasper Lake SoCs, ADL-N has found its way into a variety of entry-level computing systems including notebooks and compact desktops.

ASRock Industrial's lineup of ultra-compact form-factor (UCFF) systems - the Intel-based NUC BOX series and AMD-based 4X4 BOX series - has enjoyed significant market success, allowing the company to regularly introduce products based on the latest Intel and AMD offerings. At the same time, the expanding market for compact computing systems has also brought many Asian companies such as ACEMAGIC, Beelink, GEEKOM, GMKtec, and MinisForum into play. These vendors are essentially brands for OEMs / ODMs with experience in product design and manufacturing experience. The rise of e-commerce has allowed them to find an outlet for their product designs via direct-to-consumer sales.

As ADL-N ramps up, we are seeing a flood of low-cost compact desktop systems based on it from multiple vendors. We took advantage of this opportunity to source two contrasting ADL-N mini-PCs - the ASRock Industrial NUC BOX-N97 and the GMKtec NucBox G2. Though both systems utilize a quad-core ADL-N SoC, the feature set and target markets are very different. The review below provides a detailed analysis of the system features, build, performance profile, and value proposition of the NUC BOX-N97 and the NucBox G2.

Introduction and Product Impressions

Rapid strides have been made in CPU performance and power efficiency over the last decade. This has resulted in compact systems equipped with sub-15W TDP SoCs becoming powerful enough to replace bulky desktops for many use-cases. This trend gained mainstream attention with Intel's introduction of the ultra-compact form-factor (4in. x 4in.) NUC in the early 2010s. The 4x4 form-factor continues to hold sway even today, as evidenced by the variety of UCFF systems introduced by multiple vendors every year. The ASRock Industrial NUC BOX-N97 we are looking at in this review utilizes the tried and tested 4x4 form-factor.

The 4x4 form-factor was chosen in order to be able to accommodate a 2.5" disk drives and SODIMM kits. Since that time, both storage and memory technologies have evolved significantly. High-capacity M.2 2242 / 2230 SSDs are becoming common, and soldered RAM is not being met with as much derision as before. These have contributed to some vendors introducing micro-PCs with a sub-4x4 footprint. The second system evaluated as part of this review, GMKtec's NucBox G2, is one such micro-PC measuring 3.4 in x 3.4 in.

ASRock Industrial NUC BOX-N97

ASRock Industrial has been serving the industrial systems market with compact boards and mini-PCs since the days of Intel Skylake (6th Gen) / Braswell. Having taken over ASRock's Beebox design, the company's product releases in this category have had a regular cadence.

The company has been maintaining a line of actively-cooled 4in. x 4in. NUC BOX systems based on Intel's low power microarchitecture. In the Tremont era, the company introduced the Elkhart Lake-based NUC BOX-J6412. This was the successor of the NUC BOX-3xx0 based on the Braswell SoCs. The NUC BOX-N97 is the company's latest product in the lineup. This Gracemont version utilizes the ADL-N Intel Processor N97. Similar to other products in the NUC BOX line, the system if offered as a barebone, with the ability to accommodate a single DDR4-3200 SODIMM and either a 2.5" SATA drive or a M.2 2280 SATA / NVMe SSD.

In addition to the main unit, the NUC BOX-N97 package comes with a VESA mount and corresponding screws, and a 65W (19V @ 3.42A) power adapter. A geo-specific power cord is supplied along with a product overview / installation brochure. The gallery below provides a comprehensive look at the chassis design and I/O ports placement. The space for the 2.5" drive is on the underside of the unit (the one that needs to be separated out in order to install the RAM and disk drive). The SATA cable is affixed to the underside, as shown in one of the gallery pictures.

We opted to install a 16 GB Crucial DDR4-3200 CL 22 SODIMM in the system along with a SK hynix Gold P31 NVMe SSD. It must be noted that the M.2 slot accepts both SATA and NVMe SSDs, with the latter operating at PCIe 3.0 x1.

Every NUC BOX system reviewed before had been equipped with dual SODIMM slots. The NUC BOX-N97 has only one slot, though (as the ADL-N SoCs have only a single memory channel). Except for the DRAM slot, the rest of the NUC BOX-N97's internals are very similar to the other NUC BOX systems reviewed before. The system uses a notebook-style cooler. There are no bells and whistles, and the chassis design and thermal solution are tried and tested versions.

GMKtec NucBox G2

The GMKtec's NucBox G2 is the company's follow-up to the still-active Jasper Lake-based NucBox 7. This micro-PC family adopts the ports-all-around scheme that we already saw in last week's review of the ACEMAGIC T8 Plus. Like the ACEMAGIC system, the NucBox G2 also comes with soldered LPDDR5 RAM. A semblance of upgradability is maintained, thanks to the use of a M.2 2242 SATA SSD. The system is not available as a barebone kit. Our review configuration came with 12 GB of LPDDR5-4800 RAM and a 1 TB SATA SSD with Windows 11 Pro pre-installed.

In addition to the main unit, the NucBox G2 package comes with a HDMI cable, wall mount with associated screws, an user manual, a warranty card, and a 36W (12V @ 3A) geo-specific wall wart with a Type-C output. Unfortunately, this is a non-conforming USB Type-C application, and the wall wart can't be used reliably with other devices conforming to USB-PD sink standards. The adapter can only be used with the Type-C power input-only port of the NucBox G2. The top part of the main unit can be pried off easily to expose the M.2 2242 SATA SSD slot. GMKtec also offers an alternative colored top panel. Teardown pictures are provided in the gallery below along with a look at the placement of various I/O ports.

The teardown pictures show the M.2 SATA SSD surrounded by a plastic frame on which the WLAN antenna are mounted. Unscrewing the underside reveals a LED lighting base connected to the main board with a ribbon connector. A small notebook-style fan is also visible along with the associated copper heat spreader. The LED lighting base has open vents allowing the fan to suck in air and blow it out over the heat spreader fins. Taking off the heat sink and fan reveals the ADL-N package and a single DRAM package that incorporates four 24 Gbit Micron dice.

The soldered RAM is not user-upgradeable. However, the M.2 2230 slot for the WLAN component is accessible under the M.2 SATA SSD slot. The pre-installed SSD is from FuturePath, and seems to have the same SSD controller manufacturer as the FPT310 SSD seen in the ACEMAGIC T8 Plus review.

The NucBox G2 came with Windows Pro OS pre-installed, but we had to wipe it and install Windows 11 Enterprise to keep the testing environment consistent across different systems. The full specifications of the two review samples (as tested) are summarized in the table below.

    n100 vs n200, n200 is faster. That I can understand
    n100 vs n97, n97 is faster. Who came up with this naming scheme?
  • NextGen_Gamer - Friday, October 6, 2023 - link

    Total agree, Intel had the opportunity with a new new series (Intel Processor N) and still messed it up. N50 is 2 cores, 6-Watts. N97, somehow, is 4 cores, at 12-Watts. Then you move "up" to N100, 4 cores, but at 6-Watts. N200 is the same as N100, but gets a small clockspeed bump and finally gets you the full Intel UHD Graphics @ 32 EUs. Then Intel went ahead and named the 8 core ones to Core i3 N300/N305 - why throw the i3 in there??? Why not just keep it as Intel Processor N300? At least the split between N300/N305 makes sense: N305 just gets a higher TDP, and nothing else.
  • mode_13h - Sunday, October 8, 2023 - link

    Lots of good points, here. However, the part about N97 can be partially explained in that I believe it's not one of their models meant for things like Chromebooks. Rather, it's more of a specialty/embedded part. If you look at them on, the N97 lists its product segment as Embedded, while the N100's vertical segment is Mobile.

    The fact that they're aimed at different segments means their specs don't necessarily have to plot along the same continuum. Though, it'd be nice if they did.
  • NextGen_Gamer - Monday, October 9, 2023 - link

    @ mode_13h - Ahh, you are right, that does explain it, a little at least haha. I am personally waiting for a nice NUC-type box to come around with the N200 in it, and *hopefully* a SO-DIMM for DDR5 and M.2 2280 for the SSD.
  • mode_13h - Monday, October 9, 2023 - link

    Beware of how many lanes are active on the SSD, though. PCIe 3.0 x1 is pretty disappointing, though it still beats SATA!

    I was expecting to see at least x2 - these SoCs don't have a ton of I/O, but they have one more lane than the previous generation. Going back 2 generations, Gemini Lake had only PCIe 2.0 x6! So, you'd really think they could spare at least 2 lanes for NVMe.
  • NextGen_Gamer - Tuesday, October 10, 2023 - link

    I currently have the Intel NUC11ATKPE, with the Pentium Silver N6005 processor. My WD SN850 is running at PCIe 3.0 x2 right now, but I really don't see why these newer Alder Lake-N systems wouldn't want to spare a full PCIe 3.0 x4 for the M.2 slot. I would rather sacrifice other I/O and have your storage subsystem running as fast as it can.
  • deil - Wednesday, October 11, 2023 - link

    Well, its buldozer kind of thing.
    It's NEWER, with ddr5 instead of ddr4 AND $100 cheaper.
    If your order them by price, performance matches.
  • - Friday, October 6, 2023 - link

    Are the memory timing right? Seems like the ASROCK is a stronger box. Main diff is 2W of power
    at idle? And $30 bucks?
  • ganeshts - Saturday, October 7, 2023 - link

    Yes, memory timing is for LPDDR5-4800 (it is not comparable against DDR4-3200 timings or DDR5 timings).

    The ASRock box is substantially different from the G2 - check the I/Os and also more importantly it has scope for additional user configuration wrt RAM capacity and SSD capacity. The G2 has soldered RAM.

    Btw, the difference in price is not $30, but more than $100. The G2 is ready out of the box for $230 with Win 11 Pro pre-installed. The NUC BOX-N97 needs RAM, SSD / HDD, and OS to be supplied by the user.
  • mode_13h - Sunday, October 8, 2023 - link

    Also, the NUC BOX-N97 is from ASRock Industrial, and therefore presumably built to a higher standard and with better support!

    I've never heard of GMKtek - do they offer real support for US-based customers? What's the warranty on that unit? How long do you think they'll keep releasing BIOS updates for it?
