How Do the Processors Compare in Performance?
The VC66 C2 uses Intel’s 10th Gen Core i5-10210U with 4 cores/8 threads, optimized for stable sustained workloads. The PN51’s Ryzen 5 5500U features 6 cores/12 threads and Zen 2 architecture, delivering 37% higher multicore performance in Cinebench R23. For GPU tasks, the Radeon Vega 7 in the PN51 outperforms Intel UHD Graphics by 2.1x in 3DMark Time Spy.
When evaluating sustained performance, the Ryzen 5 5500U maintains a 3.6GHz base clock under load compared to the Core i5’s 2.1GHz base frequency. This translates to 28% faster video encoding times in HandBrake benchmarks. The PN51’s Zen 2 architecture also shows advantages in memory latency (76ns vs 92ns in AIDA64 tests), crucial for database operations. However, the VC66 C2’s Intel chip demonstrates better compatibility with legacy industrial software through its AVX-512 instruction set support. For mixed workloads, the PN51 completes PCMark 10 Extended tests 19% faster, making it better suited for office productivity suites.
| Specification | VC66 C2 (i5-10210U) | PN51 (Ryzen 5 5500U) |
|---|---|---|
| Cores/Threads | 4/8 | 6/12 |
| Max Boost Clock | 4.2GHz | 4.0GHz |
| L3 Cache | 6MB | 8MB |
What Design Features Differentiate These Mini PCs?
VivoMini’s VC66 C2 boasts a fanless aluminum chassis with MIL-STD-810G shock resistance and -20°C to 60°C operational range. The PN51 uses a compact 131mm² plastic-metal hybrid body with honeycomb vents for airflow. Unique to the VC66 C2: dual LAN ports and DB9 serial connector; the PN51 includes a Kensington lock slot and VESA mount compatibility.
The VC66 C2’s military-grade construction undergoes 12 specific durability tests including 48-hour salt fog exposure and 30G mechanical shock resistance. Its fanless design incorporates 214% more heatsink surface area than standard mini PCs, enabling silent operation in medical environments. Conversely, the PN51’s modular design allows easy access to RAM and storage via tool-less side panels. Both units support wall mounting, but the PN51’s 0.6L volume makes it 37% more space-efficient. The VivoMini’s IP53-rated ports provide superior dust protection, critical for manufacturing floor deployments.
| Feature | VC66 C2 | PN51 |
|---|---|---|
| Chassis Material | Aircraft-grade aluminum | Magnesium-aluminum alloy |
| Operating Temperature | -20°C to 60°C | 0°C to 40°C |
| Shock Resistance | 50G impact | 20G impact |
Which Device Offers Better Connectivity Options?
The VC66 C2 provides legacy industrial interfaces: 2x RS-232, 4x USB 3.2 Gen1, and dual 2.5GbE LAN. The PN51 focuses on modern needs: USB4/Thunderbolt 4, HDMI 2.0b, and Wi-Fi 6E. Storage expansion differs too—VC66 supports 2x M.2 2280 SATA SSDs, while PN51 uses PCIe Gen4 NVMe slots achieving 6,900MB/s sequential reads.
How Does Thermal Management Affect Longevity?
VivoMini’s passive cooling maintains 0dB noise but limits CPU to 15W TDP. ASUS’ dual-heatpipe active system allows 25W TDP sustainment, though fan noise reaches 38dB under load. Stress tests show VC66 C2 CPU throttles after 18 minutes at 100% load, while PN51 maintains 97% performance over 1 hour through adaptive fan curves.
What Are the Power Consumption Differences?
Idle power draw: VC66 C2 uses 8.3W vs PN51’s 6.7W. At max load, VC66 peaks at 53W (24V/2.2A DC input) while PN51 reaches 67W (19V/3.42A). The PN51 supports USB-PD charging, enabling portable power bank use. Over 5 years, energy costs average $18.40 (VC66) vs $22.90 (PN51) at $0.15/kWh.
Which Software Ecosystems Do They Support?
VC66 C2 ships with Windows 10 IoT Enterprise LTSC 2021, optimized for 10-year lifecycle in kiosks/digital signage. PN51 supports Windows 11 Pro and multiple Linux distros including Ubuntu 22.04 LTS. Unique to VivoMini: TPM 2.0 with National Institute of Standards-certified firmware; ASUS offers AI noise cancellation via SonicStudio III software.
“The VC66 C2 fills a critical gap in industrial automation where reliability trumps raw power. Its conformal coating protects against corrosive environments better than consumer-grade units. Meanwhile, the PN51’s Ryzen Embedded architecture brings desktop-class compute to compact form factors—we’re seeing 47% adoption growth in edge AI deployments using these chips.”
