The introduction of the Intel NUC in the early 2010s kickstarted the ultra-compact form-factor (UCFF) trend for desktop systems. Processors with TDPs ranging from 6 - 15W formed the backbone of this segment in the initial years. Intel and AMD have been officially allowing configurable TDPs for their notebook segment offerings for a few years now. This has prompted some vendors to introduce UCFF systems with regular 45W TDP processors (albeit, in cTDP-down mode).

GEEKOM, the private label brand of Shenzhen Jiteng Network Technology Co., has been on a roll lately with the introduction of multiple UCFF systems in the last year. The brand has become an avenue for the company to market excess inventory from their OEM / ODM production runs. As a result, we are seeing the introduction of fully configured systems based on older CPU generations, but at extremely attractive price points. The GEEKOM A5 is one such product.

The system is available in only one configuration - a Ryzen 7 5800H CPU along with a 512 GB SSD and 32 GB of RAM. The company sent that over to put through our evaluation routine for small form-factor computing systems. This review explores the performance profile and value proposition of the system, along with a discussion of factors that might tempt consumers to opt for it despite the use of a processor from early 2021.

Introduction and Product Impressions

Small form-factor (SFF) systems are replacing bulky desktops for many use-cases. The rapid growth in this segment has led to the rise of many Asian vendors focusing on these systems. GEEKOM is a private label brand of Shenzhen Jiteng Network Technology Co., Ltd. - an OEM / ODM for small form-factor computing systems. The company manufactures both Intel and AMD-based systems. The private label started off with a few entry-level systems (such as the MiniAir 11) , but has since branched out to introduce machines with leading-edge processors. We recently took a look at their Raptor Lake-H-based Mini IT13, but the focus today is on the GEEKOM A5. This system is equipped with a relatively old AMD Cezanne SoC from early 2021.

The Ryzen 7 5800H in the GEEKOM A5 has eight cores and sixteen threads, with a Radeon RX Vega 8 integrated GPU. It is fabricated in TSMC's 7nm processor. At the time of its introduction in the 2021 CES, the SoC was slotted right in the middle in AMD's Ryzen 5000 Mobile H-series lineup.

In order to make up for the use of an old processor, GEEKOM is being very liberal with DRAM capacity (32 GB of DDR4-3200) and has also used a relatively high-performance DRAMless Gen 3 SSD (512GB of SK hynix 176L 3D TLC behind a Maxio SSD controller in the Lexar NM620). The entire package is being marketed with a sub-$400 price point - essentially less than half of what such an UCFF system would have cost, had it been purchased in 2021.

GEEKOM's package for the A5 is spartan - the main unit is accompanied by a welcome card, VESA mount with associated screws, an installation guide, HDMI cable, and a 120W (19V @ 6.32A) AC adapter with a geo-specific power cord.

The main unit clocks in at 117mm x 112mm x 49.2mm. The system is sized to accept a 2.5" drive. The case design is essentially the same as the Mini IT13. The form-factor is meant to deliver functionality similar to the full-height mainstream NUCs. The larger dimensions allow for a wider variety of ports in the systems compared to regular UCFF systems that forego the 2.5" drive support.

GEEKOM does not sell barebones versions of the A5. A SSD, DRAM, and a pre-installed copy of Windows 11 Pro are also provided.

Unlike the other AMD-based GEEKOM system we had reviewed before, the board and chassis design are fairly straightforward and similar to the NUCs.

The DDR4 SODIMM slots and the Gen3 x4 M.2 SSD slots on the motherboard are pre-populated in the GEEKOM configuration. The WLAN / BT module is under the NVMe SSD slot (similar to the mainstream NUCs). There is a metal frame that is built around the 2.5" drive slot, and a thermal pad is affixed to it to provide heat transfer support from the M.2 2280 NVMe SSD. Our review configuration was equipped with 2x Shenzhen Wodposit Tech. WPBH32D408SWM-16G DDR4-3200 SODIMMs and a Lexar NM620 (2023 model) Gen3 x4 M.2 2280 NVMe SSD. Windows 11 Professional came pre-installed.

The full specifications of the review sample (as tested) are summarized in the table below. The Ryzen 7 5800H has a TDP of 45W, and a minimum power (cTDP-down) of 35W. As we shall see in our BIOS options analysis and detailed investigation into the thermal characteristics in a later section, the form-factor of the system and the notebook-style thermal solution restricts the operation of the processor to a 35W cTDP mode.

    Yes. Inferior, yet pricier than AMD counterpart.

    All I see here is outdated hardware. Gen3 and not Gen4 or better. No USB 4. Etc. Great unit if you are placing it in a Mall display.

    An ASRock X300 Desk Mini with an STX/AM4 MB and Ryzen 5700G can be had for a little over $320 and the X300 Desk Mini comes with 2, M.2 x4 PCIe link slots and space for 2 SATA internal SSDs. And one of the M.2 slots can be fitted with an M.2 to OCuLink adapter and there's plenty of Knockouts on the X300 Desk Mini's case to rout the OCuLink cable out of the case easily sans any need to open the case afterwards. So with Knockouts on the case for an optional OEM 2 USB port kit or other knockout some OCuLink port could be retrofitted is one gets creative!

    As an owner of a MiniITX board with a 5700G I regret to inform you that external PCIe lanes only run at x3 with that CPU, even for storage. So while on paper that X300 looks better than this mini box, in practice it's got the same limitation. The 5700G is overall not quite as powerful as this mini box at equivalent wattages, although thanks to being an ITX sysem I run mine at 65W which likely outperforms this box substantially.

    The M.2 PCIe Lanes on processor side of the Board is listed as PCIe 3.0 X4 lanes while the M.2 on back side of the MB limited to what's listed so not according to ASrock's specifications page for the X300 Desk Mini:

    - 2 x SATA 6Gb 2.5-inch 7mm/9.5mm Hard Drive (RAID 0/1)
    - 1 x Ultra M.2 (2280) PCIe Gen3 x4 SSD Slot
    - 1 x Ultra M.2 (2280) Slot
    - PCIe Gen3 x4 (Renoir, Picasso and Raven Ridge APU)
    - PCIe Gen3 x2 (Athlon 2xxGE series APU)

    And what Gen3 that not enough for you that you have to use Gen4? As for USB4, I agree. And you can get it if you buy mini-pc with ryzen 6800u/h or 7735H.

    That non-USB-C PSU brick must be a joke.
  • lmcd - Monday, December 11, 2023 - link

    Depending on your USB controller as part of the lone source of power is an anti-feature in my opinion. With laptops it's different because there's a battery, but USB-C desktop power is a "no thanks."
  • meacupla - Monday, December 11, 2023 - link

    It's a standard, and really cheap, 19V laptop power brick.
    Finding a cheap USB-C charger than can output >120W over a single port is a challenge, unfortunately. Most of them top out at 100W per port.

    200W and 240W PD cables have been available for at least 6 months, but no such charger has shown up yet.
  • stephenbrooks - Monday, December 11, 2023 - link

    The brick is nearly as large as the PC.
