We cover pitting these mini pcs against each other in a guide of its own.
Check the table below to see the hardware gap before diving into the specific features that matter for your workflow. Note that specific RAM speeds and SSD model numbers can vary by retailer, so always verify the current listing details before purchase.
| Feature | GMKtec M6 | KAMRUI Pinova P2 |
|---|---|---|
| Processor | AMD Ryzen 7 7640HS (Zen 4) | AMD Ryzen 3 4300U / 7330U (Zen 2/3) |
| Graphics | Radeon 760M (8 CUs) | Radeon Vega 5/6 |
| RAM | 32GB DDR5 (Expandable) | 16GB LPDDR4 (Soldered) |
| Storage | 1TB NVMe + Second Slot | 512GB NVMe + SATA |
| Networking | Dual 2.5 GbE | Single 1 GbE |
| Ports | USB4, HDMI 2.0, DP | USB 3.2, HDMI 2.0, DP |
When you look at the CPU generation alone, the M6 uses a newer architecture that boosts faster and handles more threads. This makes it the technical superior in almost every raw performance metric.
However, the KAMRUI P2 isn’t bad for its price. It just operates in a completely different lane. It is an efficiency-focused device, not a performance one. Understanding this distinction is key to making the right buy.
CPU and GPU: The M6 is built for gaming
The GMKtec M6 houses the AMD Ryzen 7 7640HS. This is a Zen 4 chip with 6 cores and 12 threads, capable of boosting to 5.0 GHz. It delivers roughly 30-40% more single-core performance than the older Ryzen chips found in the KAMRUI P2.
The integrated Radeon 760M graphics are the deciding factor for media and gaming. With 8 compute units running at up to 2.6 GHz, the M6 can play titles like Fortnite and Overwatch 2 at 1080p with stable framerates. It also handles 1080p video editing in DaVinci Resolve or Premiere Rush without stuttering, thanks to the newer display engines.
For content creation, the higher core count of the M6 matters when rendering. You can export 4K clips significantly faster than on the P2. The KAMRUI P2 uses a Ryzen 3 chip, which is efficient but slow by comparison.
Its Vega 5 or 6 graphics are fine for displaying video, but they cannot drive modern 3D games at playable settings. Before you buy anything, it is worth looking at evaluating mini pc performance.
If you plan to game or do creative work, the P2 is not capable enough. It will bottleneck your projects and cause frustration. The M6 is the only one of these two that feels like a true desktop replacement for these tasks.
Winner: GMKtec M6. It handles gaming, development, and heavy multitasking that would choke the KAMRUI.

RAM and storage: Expandability vs. Limitations
The GMKtec M6 comes with 32GB of DDR5 RAM in dual-channel configuration. Crucially, this memory is socketed, meaning you can upgrade it later if you need more space for virtual machines or large datasets. It supports up to 128GB in many configurations, which is rare in this price bracket.
The KAMRUI P2 has 16GB of LPDDR4 RAM that is soldered directly to the motherboard. You cannot add more RAM. If you buy it, that is the maximum memory you will ever have. This is a significant long-term limitation for power users who might open too many tabs or run local LLMs.
Storage on both machines is expandable, but the M6 supports faster PCIe 4.0 drives and dual M.2 slots. This allows you to run a high-speed OS drive and a larger storage drive separately. The P2 typically has one M.2 slot and one SATA slot, which is slower but sufficient for basic files.
If you plan to keep your mini PC for five years, the M6’s upgradeability saves money later. You can swap in faster SSDs and more RAM as technology improves. The P2 is a fixed-spec device; it is what it is on day one and day one,000. Before you buy anything, it is worth looking at pinova p2 gmktc m6 ultra.
Winner: GMKtec M6. The ability to upgrade RAM and storage makes it a longer-lasting investment.
Pro tip: Check the manufacturer's specific manual for your exact SKU to confirm maximum RAM capacity, as this can vary between production runs.
Networking: The home lab and server advantage
The GMKtec M6 includes dual 2.5 Gigabit Ethernet ports. This turns the mini PC into a capable home server, pfSense firewall, or NAS box. You can separate traffic for different networks without buying an extra adapter or USB gadget.
The KAMRUI P2 has a single Gigabit Ethernet port. While sufficient for a standard office PC or media server, it lacks the bandwidth and port separation needed for serious networking projects. If you want to run multiple isolated networks, you will need external hardware with the P2.
If your goal is to run a home lab or a high-speed network appliance, the M6 is the only one of these two that supports that use case out of the box. It is a powerful choice for hobbyists who want to learn about networks without the bulk of a rack server.
For normal users who just stream Netflix or browse the web, either machine is more than fine. The extra ports on the M6 are a bonus feature for those who need it, but they don’t hurt anyone else.
Winner: GMKtec M6. It supports advanced networking tasks that the KAMRUI simply cannot do.
Connectivity and Video Output: Who drives your monitors?
Both machines support triple 4K displays, which is great for productivity setups. The GMKtec M6 uses USB4 ports for video output, which is faster and more future-proof than standard USB-C. It also includes a dedicated DisplayPort and HDMI 2.0 port.
The KAMRUI P2 uses a single USB-C port with DisplayPort Alt Mode, alongside HDMI and a standard DisplayPort. This is sufficient for most office setups. If you run three 4K monitors at 60Hz, both machines will handle it.
However, the M6’s USB4 supports higher bandwidth for 8K displays, which is a feature most people won’t need today but might use in a few years.
USB speeds are another differentiator. The M6 offers USB4 at 40 Gbps, which is nearly double the speed of the USB 3.2 Gen 2 ports on the KAMRUI. This matters if you use external SSDs or fast external cameras. For basic thumb drives and keyboards, both feel identical.
Winner: GMKtec M6. It offers faster USB standards and more robust video output options for high-end monitor configurations.
Thermals, Noise, and Power Consumption
The GMKtec M6 has a higher TDP, often ranging from 45W to 60W depending on the configuration. This means it generates more heat and will run its fans more aggressively. Under heavy load, you will hear the fan spin up. It is not loud, but it is audible in a quiet room.
The KAMRUI P2 is an efficiency machine with a 28W TDP. It runs cooler and quieter. In a home theater setup, it will likely be completely silent even during video playback. It is the better choice if noise is your primary concern and you don’t care about max performance.
Power bills will also differ. The M6 uses more electricity under load, but for a mini PC, the difference in daily cost is negligible for most users. It costs a few cents more per month to run a server 24/7. For intermittent use, the difference is irrelevant.
Winner: KAMRUI P2. It is quieter and cooler, making it the better choice for media hubs and silent office environments.
Safety first: Always keep the vents clear of dust. Use a compressed air can to clean the fans every six months to prevent overheating.
The bottom line
Buy the GMKtec M6 if you need performance, gaming, or future upgradeability. Buy the KAMRUI P2 only if your budget is tight and your needs are strictly limited to web browsing, documents, and video playback. The M6 is the better long-term investment for most users who want a true desktop replacement in a small box.

Frequently asked questions
Can the KAMRUI Pinova P2 play modern games?
No. The integrated Vega 5 graphics are not powerful enough for modern 3D titles. You can run old games or 2D indie titles, but expect low framerates on anything recent. For gaming, you need the GMKtec M6.
Is the KAMRUI P2 RAM upgradeable?
No. The 16GB of LPDDR4 memory is soldered to the board. You cannot add or replace it after purchase. If you might need more RAM in the future, buy the GMKtec M6 instead.
Which mini PC is quieter?
The KAMRUI P2 is generally quieter at idle and light loads because it has a lower TDP processor. The GMKtec M6 will spin up its fans more often under heavy gaming or rendering tasks, but it remains relatively quiet for its performance.
Does the GMKtec M6 support USB4?
Yes. The M6 features USB4 ports that support up to 40 Gbps speeds and can output 8K video. The KAMRUI P2 typically uses USB 3.2 Gen 2 Type-C ports, which are slower.
