Size: 32GB DDR5+512GB NEW H 255
This is specifically for the K12 with the Ryzen 7 H 255. Honestly, not a bad deal. The CPU is pretty good for its class, and has very acceptable integrated graphics. The H 255 is seemingly only sold to the chinese market, has no real documentation officially (as of the time of writing), and is essentially a recycled die from better chips that didn't meet the cut so to speak (at least as far as I can find), but I don't see any of those as a real problem; die recycling is perfectly fine if it actually works and is stable, and AMD is usually pretty good at the latter... and it makes me feel a little better that AMD can save something that would otherwise end up being e-waste. Despite the borderline unofficial nature of the CPU, I have not experienced any performance issues, instability, or crashes of any kind after a few weeks. Note that I updated the BIOS and microcode immediately after receiving the unit, and I suggest everyone do the same. The unit itself is from GMKtec, which is a chinese company. However, there were some (good) surprises in the box that tells me they actually cared about the end user experience, though possibly only just enough to make sure that the average joe blow didn't immediately return it because they got pissed off at something that would honestly be Microsoft's fault (eg. the horrendous OOBE for Windows). I choose to believe they actually care though, and somewhat reinforcing that, my email to them was answered the next day (I'll get to what the contents of that was later). The specs of the unit, aside from the CPU which is pretty good itself, are actually darn incredible. OCuLink is a quasi-rare connector, but an *extremely* welcome one! That significantly improves the unit's lifespan and enables mostly modern gaming, provided you genuinely do the research into how to use it (remember, don't plug or unplug it when the PC is on!), though it can already handle light-medium gaming with just the integrated graphics. Though I have not tried the OCuLink port yet, I have no reason to believe it doesn't work or anything like that. USB4 is also extremely welcome, and I can confirm that it not only works, but it follows best practices of how to implement the protocol. Since the port does do PCIe tunneling, it should work with all Thunderbolt 4 appliances out of the box. GMKtec could have taken the cheap way out and omitted this detail, but they did not. Absolutely incredible to have both of these available. There are also, seemingly (I have not opened the unit up yet, no reason to), three M.2 slots, one at Gen4x4 and two at Gen4x2, which is perfectly fine in terms of speed and great in terms of how many slots they offer. I cannot think of any other mini PC with this level of overall connectivity. You lose out on some external USB connectors that would otherwise be present, but USB4 seriously more than makes up for it. The dual 2.5G LAN ports are just the whipped cream on top of all this. Though, not all can be as good. There is no S3 power state support in the firmware, so you're stuck with shutting down the computer, hibernating it, or relying on Microsoft's absolutely abysmal "implementation" of sleep in the form of modern standby (S0). This was confirmed in my aforementioned email to GMKtec's support. Oh well, I have the whipped cream but miss out on the cherry. This may be an oversight on GMKtec's part, but it may also be difficulty getting S3 implemented with OCuLink. Don't know exactly how that works. I'm tempted to knock a star off for this, since S3 is a very, very nice power state to have available, but it's something I'm personally not terribly concerned about, especially with everything else so good. Please, if you're reading this GMKtec, add it in a BIOS update! Would love to see it! There may also be an issue with the TPM, specifically in regards to when the firmware tells the OS to initiate S0 sleep (eg. from the power button short pressed). In such an event, when the computer resumes from S0 the TPM will either fail or lock up. This may be an issue with Windows, or with the TPM, or with just my unit, and it requires a reboot to clear it up. Either way, my way around it is to leave the unit turned on or to just shut it down, but again it's not a concern for me personally, and YMMV. Overall, I would recommend this unit. Though I have not opened it to inspect the internals, nor tested the OCuLink connector yet, I see great value in this unit, and I imagine I will keep it around for a very long time, getting significant usage out of it. I would give it 4.5 stars if that were possible, but for Amazon I will leave it at 5.

Size: 32GB DDR5+1TB 7840HS
Pros: - Small - Powerful (8 Zen4 cores, 16 logical CPUs, Radeon 780M graphics, HX power spec) - (Relatively) low power consumption from being a laptop CPU (Though the HX is not as efficient as the U version) - Comes with a good amount of good quality RAM from a name brand - 2x 2.5G nics - USB4 port (haven't tested it out yet, other reviewers had issues) - Good cooling - Quiet at idle (YMMV) Cons: - Came with a moderately used Lexar SSD - Windows 11 (wiping that put even more write cycles on the SSD) - A U power spec option or BIOS support for lowering TDP would have been nice for lower power consumption - No SATA support - Ethernet controllers are Realtek, not Intel - Wifi also not Intel This is just an initial review, but out of the box I noticed that the 1TB SSD that was included in this GMKtek K6 mini PC had logged about 86 hours of usage in SMART, as well as over 8TB written and 7TB read on this 1TB Lexar SSD. That seems like a lot more than initial imaging and burn-in to me. Over 8 full write cycles for every memory cell will have an impact on the SSD's lifespan. I am only using the included SSD as a supplement to my main SSD, so it's not a big issue, but buyer beware! Also, the SSD did come with an extra heatsink pre-installed. That may improve the longevity of the disk enough to compensate for a lot of the usage. I removed it from the included drive and installed it on my 3rd-party drive instead since I use that one more. Overall, this system seems to work well. I wiped Windows 11 and am using proxmox on it. The Ryzen 7840 CPU is really great for my purposes as a VM server / AI host. In July 2024 I got this for $509. With the 32Gigs of ram and a 1TB SSD that is functioning, at least, it's a really amazing deal. Similar machines from other manufacturers cost hundreds more without the RAM or SSDs, so I'm not going to complain too loudly. In fact, I think it's a great deal from Amazon and GMKtec. Time will tell how well this machine holds up, but the construction seems solid, the cooling seems to be well-designed for this form factor with a fan for the CPU being pretty standard, but a second fan for cooling all the other components is a nice addition that you don't see in some competitors. I will update this review with any developments.
