AMD mobile CPUs power new mini-ITX motherboards — Zen 3 or Zen 4 chip onboard, two M.2 slots, and four 2.5G Ethernet ports
Mobile Zen 3 and Zen 4 chips make their way to the desktop.
Mini-PC hardware designer Changwang has launched mini-ITX motherboards for NAS computers equipped with mobile Zen 3 and Zen 4 APUs from the Ryzen 7000 series (via HXL). While the motherboards come with mobile Ryzen APUs, the board itself uses the standard mini-ITX form factor, complete with an x16 PCIe slot for gaming GPUs, two M.2 slots for PCIe 4.0 SSDs, and a plethora of Ethernet ports.
Though Changwang's new motherboards appear to be the first to utilize mobile Ryzen 7000 APUs, they're not entirely unprecedented. A few months ago, Minisforum launched a mini-ITX motherboard with a Ryzen 7 7745HX CPU, a mobile version of the Ryzen 7 7700X. Erying Technology, another Chinese manufacturer of mini-PC products like Changwang, launched motherboards integrated with mobile 14th Generation Intel CPUs.
Changwang offers four different Ryzen 7000 APUs: the Ryzen 9 7940HS, the Ryzen 7 7840HS, the Ryzen 7 7735HS, and the Ryzen 5 7640HS. While the eight-core Ryzen 9 7940HS and Ryzen 7 7840HS are identical, except for the former having a 100 MHz boost clock and the Ryzen 5 7640HS is just a six-core version of the Ryzen 7 7840HS, the 7735HS is a bit unique. Instead of being based on the Zen 4 Phoenix chip, it uses the Zen 3 Rembrandt chip used for the Ryzen 6000 series, and this may be the first time this chip has ever come to a standard desktop motherboard.

Overall, the features included on the Changwang motherboard are decently impressive. There are two M.2 slots capable of servicing PCIe 4.0 SSDs, though because Phoenix APUs only have 16 total PCIe slots, installing one or two M.2 SSDs means lowering the x16 slot's lanes from 16 to 8. The rear I/O includes four USB ports, but one has USB4 support, which isn't too familiar on the desktop. However, most of the I/O area is occupied by four Ethernet ports capable of 2.5 gigabits, which would undoubtedly make any networking enthusiast happy.
These motherboards with integrated Ryzen 7000 APUs might have been pretty killer a few months ago, but just days ago, AMD launched its Ryzen 8000G series APUs for the desktop, which use the same Phoenix chip that the Ryzen 7040HS chips use. Ryzen 8000G chips are a little faster, more customizable, and can be installed and upgraded like regular desktop chips, which are all significant points against Changwang's motherboard.
However, when it comes to price, Changwang has the advantage. With a cost of 2,888 Yuan or about $400, the Ryzen 7 7840HS-equipped board looks pretty decent. A Ryzen 7 8700G retails for $329, and the cheapest AM5 mini-ITX boards cost $130 at minimum (and come with the A620 chipset). No AM5 motherboards, however, come with four Ethernet ports, a unique selling point for Changwang's Ryzen 7000 motherboard.

FWIW, this MoDT 'mobile on desktop' model actually comes with the latest Ryzen 7 8845HS CPU support as well (see the image embedded below).
Even though the specs also list the Ryzen 5 7640HS, the company is planning to drop the idea to include this particular SKU (confirmed this via the AIB board channel forums. Some say there was a typo error in the marketing specs sheet).
But in any case, it would be nice to have the Ryzen 7 8845HS on this board as well, the latest "HAWK POINT" Zen 4 processor. This would add some extra cost to this MoDT board though. But these MoDT boards don't allow any upgradability or any replacement option.
And, similar to the recently released Ryzen 8000G APUs, the CPU's TDP can be unlocked to 65 Watts via the BIOS, from the default 54 Watts (applies to all CPUs on this board).

Actually the main selling point of this board isn't for Gaming though, as the company is targeting Home servers, NAS, and network/storage devices. The board also supports two SFF-8643 ports, for additional 8 SATA ports as well (so a total of 9 SATA drives supported by this board).

thestryker This would basically make for the most fully featured low power NAS.Reply
I really liked their last NAS boards, but the SoC wasn't powerful enough so I didn't get one. They've since updated that one to ADL-N which makes it more functional. They did make a clever low footprint NAS case, but it's also 6 drives so I'm curious if theyll adapt it or not.
I have two minipc router boxes built using their boards and they've been pretty good. They have some of the most interesting board designs out there. -
digitalgriffin Great value for a utility box provided they are Intel networking chips. But what CPU cooler can you use? It's non standard height.Reply -

It has mounting holes for LGA1700, and it even has an optional factory heatpipe cooler. The factory heatsink looks like an AXP-X47.digitalgriffin said:Great value for a utility box provided they are Intel networking chips. But what CPU cooler can you use? It's non standard height. -
TechLurker Given the integrated graphics, it seems ideal to pair it up with a smart raid/storage card, that has built-in bifurcation, esp. if one/both M2 slots are used for storage, and go for a serious home server.Reply
I do wonder if the M2 slots would permit an M2 to 10GbE Ethernet Adapter. -

Most likely aliexpress/taobao/CWWK like the rest of their stuff. Periodically they make their way to Amazon sellers, but it's all the same hardware just a matter of who you want to facilitate it. Two versions of the ADL-N NAS boards launched in Dec and Jan respectively so I'd expect sometime this month or next at the earliest.digitalgriffin said:Great. How do we get one?

thestryker I didn't login to check to see which aliexpress store I purchased from before so I can't speak to whether or not this one is solid (if you've never used aliexpress there tend to be several stores with very similar names). Here's the first listing for one of these boards: https://www.aliexpress.us/item/3256806342934461.htmlReply
The listing has all of the details, but to address some of what wasn't covered in the article: LGA 1700 cooler compatibility, they're i226-V NICs and it claims to support ECC (it's most likely accurate, but you never know). -

I'm pretty sure there are add-in cards that can do bifurcation, meant for use with motherboards that don't support bifurcation normally (or have more limited bifurcation options). An old one for example was this IO Crest card that had a bridge chip allowing all 4 drives to be seen by the OS even on mobos that don't support bifurcation (but that one is x16, and no idea if it can operate on x8 with reduced speed).Deleted member 2824971 said:Bifurcation isn't a function of the add-on cards, but of the onboard chipset or SoC and typically needs BIOS support to initialize the root ports accordingly and before booting.
Those were the ones I was thinking of (specifically, the few x8 options available out there), which could in theory help offset the x8 limitation while still allowing 4 or more M2 drives to show up (the few x8 PCIe 4.0 cards that support 4 NVMe).
The theoretical alternative I had in mind is something like a Synology E10M20 x8 card in that can do 10GbE + 2 NVMe, leaving the other NVMe slots free for other adapters like you've mentioned.
In either case, taking your ideas into account, such add-in cards could theoretically offer even more expansion if any of the slots can present other adapters, allowing for multiple SATA SSDs or even some old-school high-capacity HDDs.
Now these specialty boards seem even more tempting to play around with. -
das_stig Interesting motherboard, good cpu, plenty of memory, 2.5G NICS, now if only it had more slots, to have a more SAS/SATA connections for NAS and some wifi cards for AP, AIO server/ router and NAS.Reply
