(K12 – Ryzen 7 H 255) Great value, exceptional hardware and connectivity
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.

Alles super geklappt.Immer wieder gerne

Este mini PC tem funcionado muito bem neste um mês que tenho usado ele. Comprei por 4.500, preço bem mais baixo do que as opções com o processador 8845HS.O processador AMD Ryzen 7 7840HS é competente e praticamente idêntico ao 8845HS, com 8 cores rápidos, e não esquenta demais (temperatura máxima permitida é 100°C, não passa de 85°C em uso pesado aqui), devido ao bom sistema de esfriamento. Alguns compradores reclamam do barulho dos ventiladores internos (tem dois, um pequeno em cima e um maior embaixo), mas a minha unidade é bem silenciosa. Está rodando uns programas para mim que usam 50% do processador e cerca de 73°C o dia todo, todo dia (24/7).A placa de vídeo é a 780M, a mesma do 8845HS, e é bastante potente para uma placa integrada, suportando bem jogos médios e alguns pesados com configurações mais modestas. A BIOS dessa máquina permite alterar a quantidade de memória separada para a placa integrada.O SSD de 1TB é rápido, os 32GB de memória são suficientes para minha utilização.Vem com o Windows completo instalado e funciona bem nos meus testes, mas uso com Linux e tem sido estável.A única reclamação que tenho, que é um pequeno detalhe, é que o sistema não informa a velocidade de rotação (RPM) dos ventiladores, os softwares que mostram esse dado não suportam o sensor instalado.Atualizarei esta avaliação quando tiver mais dados sobre durabilidade.

Excelente, necesitaba una PC con con Xion Oculink para conectar una GPU externa y mi vieja PC no tenía ni USB 4.0, esta PC tiene lo que necesitaba.
