The AMD Ryzen 9 7940HS processor in the MINISFORUM UM790 Pro features 8 cores, 16 threads, and a max boost clock of 5.2GHz. Built on Zen 4 architecture, it delivers 30% faster multi-threaded performance than previous generations. Combined with Radeon 780M graphics, it supports 4K gaming and ray tracing, making it ideal for AAA titles like Cyberpunk 2077 and Elden Ring at medium-high settings.
Why Is DDR5 Memory Critical for Mini PC Performance?
DDR5 RAM in the UM790 Pro offers 4800MHz speeds, doubling bandwidth compared to DDR4. This reduces latency during data-intensive tasks like gaming or 3D rendering. With 16GB default capacity (upgradable to 64GB), it ensures smooth multitasking, allowing users to stream, game, and run background apps without frame drops. DDR5’s improved power efficiency also minimizes thermal throttling risks.
Beyond raw speed, DDR5 introduces on-die ECC (Error-Correcting Code) memory, which automatically detects and fixes minor data corruptions. This feature is particularly valuable for content creators working with large video files or 3D renders. The technology also supports bank group refresh, enabling partial array updates instead of full memory refreshes – a key factor in reducing power consumption by up to 20% compared to DDR4 modules.

Can the UM790 Pro Support Dual 4K Displays for Multitasking?
Yes, the UM790 Pro includes two HDMI 2.1 ports and two USB4 ports with DisplayPort Alt Mode. This setup enables simultaneous 4K@144Hz output across four monitors. Professionals can leverage this for video editing workflows, while gamers benefit from immersive multi-screen setups. The Radeon 780M GPU supports FreeSync Premium, eliminating screen tearing in high-FPS scenarios.
How Does WiFi6E Improve Connectivity in Gaming Mini PCs?
WiFi6E offers a 6GHz band, reducing interference from legacy devices. With speeds up to 9.6Gbps and lower latency, it’s optimal for cloud gaming via Xbox Cloud or NVIDIA GeForce NOW. The UM790 Pro’s dual-band AX210 card also supports MU-MIMO, allowing stable connections for multiple devices. Bluetooth 5.3 enhances peripheral compatibility with LE Audio and lower power consumption.
The 6GHz spectrum provides 59 additional 20MHz channels, effectively eliminating congestion in dense urban environments. This proves crucial for competitive gamers where even 5ms latency reductions can impact match outcomes. The UM790 Pro’s antenna design incorporates beamforming technology, focusing signals toward connected devices for 30% stronger reception compared to traditional omnidirectional setups.
| WiFi Standard Comparison | Maximum Speed | Latency |
|---|---|---|
| WiFi 5 (802.11ac) | 3.5Gbps | 10-30ms |
| WiFi 6 (802.11ax) | 9.6Gbps | 5-15ms |
| WiFi6E | 9.6Gbps+ | <5ms |
Expert Views
“Mini PCs like the UM790 Pro are redefining compact gaming,” says tech analyst Liam Carter. “The Ryzen 9 7940HS bridges the gap between desktops and portable systems, offering desktop-grade performance in a 0.5L chassis. Its dual-fan cooling is a game-changer—most rivals rely on single-fan designs, which struggle under sustained loads. For creators and gamers needing portability without compromises, this is a benchmark device.”
Conclusion
