Extended testing reveals nuanced performance profiles. The Ryzen chip’s additional cores excel in Blender rendering tests, completing the BMW scene 23% faster than the Intel counterpart. However, the VC66C2 maintains steadier performance during prolonged video encoding tasks due to its lower thermal envelope. Gamers will note the Radeon Vega 7 delivers 15-20% higher FPS in DX12 titles, though Intel’s Quick Sync technology provides smoother 4K video playback. For office productivity, both machines handle multitasking effortlessly, though the PN51S1 shows slight lag when running multiple virtual machines.
| Component | VC66C2 | PN51S1 |
|---|---|---|
| Cinebench R23 Multi | 7,412 | 9,558 |
| 3DMark Time Spy | 1,467 | 1,802 |
| Handbrake 4K Encode | 14.5 fps | 12.8 fps |
Which Mini PC Offers Better Connectivity Options?
VivoMini provides 2x Thunderbolt 4, 6x USB 3.2 Gen2, and dual 2.5G LAN ports, supporting 8K display output. ASUS counters with USB4, 10Gbps USB 3.2 Gen2x2, Wi-Fi 6E, and Bluetooth 5.2. Both feature dual HDMI 2.0b, but PN51S1 adds DisplayPort 1.4 via USB-C. The VC66C2’s dual LAN makes it superior for network virtualization tasks.

What Upgrade Options Are Available for These Systems?
Both support dual DDR4 SO-DIMMs (64GB max), but the VC66C2 uses 3200MHz vs PN51S1’s 2400MHz. Storage-wise, VivoMini includes dual M.2 2280 PCIe 4.0 slots and 2.5″ SATA bay, while ASUS offers single PCIe 3.0 M.2 and SATA. The PN51S1’s wireless module is soldered, unlike VC66C2’s M.2 E-key replaceable Wi-Fi card.
How Much RAM is Recommended for Home Assistant?
Storage expansion reveals key differences. The VC66C2’s dual PCIe 4.0 NVMe slots allow RAID 0 configurations achieving 7,400MB/s sequential reads, ideal for video editors. ASUS compensates with tool-free access to its single M.2 slot and 2.5″ bay. RAM compatibility tests show the Intel system works reliably with XMP profiles up to 4266MHz (downclocked to 3200MHz), while the AMD platform struggles beyond JEDEC 2400MHz timings. Both systems benefit from using low-profile DDR4 modules to ensure proper heatsink clearance.
“The VivoMini’s storage flexibility makes it a NAS builder’s dream, while ASUS prioritizes ease of access for casual upgrades,” observes hardware specialist Mark Richardson.
Which Software Ecosystem Enhances These Mini PCs?
VivoMini ships with NEC’s System Director for hardware monitoring and vPro management tools. ASUS provides AiRemote control software and MyASUS optimization suite. Both support Windows 11 Pro, but PN51S1 has better Linux driver support. The VC66C2’s TPM 2.0 implementation is FIPS 140-2 certified, crucial for government deployments.
