AMD-based ultra-compact form-factor (UCFF) systems are slowly gaining market acceptance, with the Zen architecture slowly catching up with Intel on both the performance as well as power consumption front. AMD's latest and greatest has been reserved for the high-end desktop market, with the parts meant for low-power / compact systems appearing a few quarters later. Zen 3-based desktop CPUs were introduced recently. However, Zen 2-based parts with 12-25W TDP (Renoir APUs) have started appearing in compact desktop systems only recently. ASRock Industrial launched the Ryzen 4000U-based 4X4 BOX-4000 series in September. The review below looks at the flagship model - the 4X4 BOX-4800U - and how it compares against the equivalent Comet Lake-U-based Frost Canyon NUC from Intel.


The PC market has grown in the last few years, thanks in no small part to ultra-compact form-factor (UCFF) and gaming systems. Intel's NUC line-up has been ruling the roost in the former category. Given AMD's focus on multi-threaded performance and core counts with the first-generation Zen microarchitecture, Zen and Zen+-based Ryzen APUs did not have good enough power efficiency and performance per watt to make a dent in Intel's success in the NUC space. ASRock Industrial did release UCFF systems based on the AMD Ryzen Embedded Processors lineup (we reviewed one such system - the 4X4 BOX-V1000M). While the GPU prowess and multi-threaded performance turned out to be appreciable aspects, the single-threaded performance, power efficiency, and driver issues made it a tough sell against competing Intel-based NUCs. The introduction of Zen 2-based APUs (Renoir) fabricated in TSMC's 7nm process changed the equation by addressing all the aforementioned weak points.

AMD prioritized the delivery of Renoir APUs to the notebook market, with mini-PCs following soon after. ASRock Industrial was again at the forefront. Along with Asus's PN50, they were one of the first to launch systems based on these parts. The 4X4 BOX-4000 series has three different SKUs with CPU core counts of 4 (Ryzen 3 4300U), 6 (Ryzen 5 4500U), and 8 (Ryzen 7 4800U) each. The last one is the flagship, and that is the one we are looking at today.

The 4X4 BOX-4800U has a 104mm x 102mm main-board housed in a 110mm x 117.5mm x 47.85mm plastic chassis. The system matches the Intel NUCs in the footprint department. The board comes with a soldered processor - the Ryzen 7 4800U belonging to the AMD Renoir APU series. It is an octa-core processor with SMT enabled (8C/16T). It can operate with a TDP configurable between 12W and 25W.

ASRock Industrial sampled us a barebones version of the system. In partnership with Patriot Memory, they also provided us with their recommended storage (Patriot P300 PCIe 3.0 x4 NVMe SSD) and memory (Patriot Signature Line 2x32GB DDR4-3200 SODIMM) for usage with the PC.

Full Specifications ASRock Industrial 4X4 BOX-4800U Specifications

The ASRock Industrial 4X4 BOX-4800U kit doesn't come with any pre-installed OS, but does come with a CD containing the drivers. In any case, we ended up installing the latest drivers downloaded off the product support page. In addition to the main unit, the other components of the package include a 90 W (19V @ 4.74A) adapter, a US power cord, a VESA mount (along with the necessary screws), a driver CD, user's manual and a quick-start guide. Installing the storage and RAM is straightforward - a matter of popping off four screws on the chassis underside and mounting the components in the appropriate slot.

The above gallery shows the package components along with the chassis design and the internal components. The system also includes support for the installation of a 2.5" drive, with a very flexible SATA power / data cable already in place.

In the table below, we have an overview of the various systems that we are comparing the ASRock 4X4 BOX-4800U against. Note that they may not belong to the same market segment. The relevant configuration details of the machines are provided so that readers have an understanding of why some benchmark numbers are skewed for or against the ASRock 4X4 BOX-4800U when we come to those sections.

    It would be great to see a comparison with new Mac Mini M1

    Ganesh why would you use a Bapco Benchmark - Mobilemark. Its results are complete crap. You must not know the history of Bapco and how its basically an arm of Intel, made for Intel chips.

    Notice how the AMD 4800U loses in every benchmark with Mobilemark and consumes more power doing it but when you look at the other results, synthetic or otherwise its mostly in AMDs favour... Intel benchmarking tools at work. This is a known thing among everyone who follows this stuff. If you want to maintain your credibility stick to independent benchmarks not ones made by the vendor for the vendors own chips.

    I feel like the 35W 4800HS, with a bit more cooling, would be a better sweet spot for this form factor.

    Speaking of which, my 4900HS doesn't idle that hot. But I did notice that it behaves quite differently when running on battery (where it drops down to 400Mhz) and on AC (where it wont go below 1GHz, even though the cores are largely asleep). Its possible that this 4800U is stuck in the Windows "plugged in" profile.
  • TheinsanegamerN - Tuesday, December 1, 2020 - link

    Given the box pulls 65 watt, there is no way it’s sticking to its TDP. A 4800hs would likely perform the same to slightly worse, given its smaller GPU
  • six_tymes - Wednesday, November 25, 2020 - link

    I hope to see these with DDR5. anyone knows when DDR5 platforms are suppose to roll out?
  • James5mith - Wednesday, November 25, 2020 - link

    2021-2022 timeframe.
  • 5080 - Wednesday, November 25, 2020 - link

    IMO the real breakthrough in this formfactor will come for AMD once they move to ZEN4/Navi based APU's on 5nm with DDR5 and USB4.0 in 2022.
  • PixyMisa - Thursday, November 26, 2020 - link

    Yes. They could add more graphics cores, but without also adding memory bandwidth that won't achieve much. DDR5 will break that bottleneck.
  • Spunjji - Friday, November 27, 2020 - link

    I'm thinking the biggest boost would come from combining DDR5 with a larger local cache a-la "Infinity cache" - 5nm should give them enough spare die area to achieve that, and it'll presumably help keep the power draw lower than stuffing the entire area with logic would.

    I just want to point out that on the spec chart, you only list "USB 3.2 Type-C", but there is clearly more to it than that, as that spec can be 10GB, 20GB, alt-mode DP, alt-mode HDMI.
    I know it's clearly marked as 10GB alt-DP in the pictures.

    aside from that
    When are manufacturers going to switch over to USB-C PD for these smaller devices? I know that USB-C PD can do 100W and this thing only eats 70W at full load from the wall.
