MINISFORUM BD790I X3D Mini ITX Motherboard - Ryzen 9 7945HX3D Power

In this review the MINISFORUM BD790I X3D is presented as a high-performance Mini ITX motherboard built around the integrated AMD Ryzen 9 7945HX3D. The bottom line: this board is for users who need flagship CPU power in a compact SFF build, offering 16 cores/32 threads and extensive cache for gaming, streaming and content creation. It stands out because it delivers near-desktop performance and triple-display support while keeping noise and power use low, making it a practical option for small-form-factor systems that cannot sacrifice performance.

Key Features

• Flagship processor: The built-in Ryzen 9 7945HX3D supplies 16 cores and 32 threads for heavy multitasking and demanding applications.
• 3D V-Cache and large cache: 144MB of L2+L3 cache with 3D V-Cache improves frame stability and reduces latency in complex game scenes.
• High-speed storage: Dual PCIe 5.0 M.2 slots let users install next-gen SSDs for very fast read speeds and sustained throughput.
• DDR5 memory support: Supports DDR5 memory up to 96GB for future-proofed multitasking and content workflows.
• Compact cooling design: Extensive heatsink coverage and an active SSD cooler keep thermals under control for prolonged high-load use.
• Modern connectivity: Triple-display outputs via HDMI 2.1, DP 1.4 and USB-C plus WiFi 6E and Bluetooth 5.3 provide flexible I/O and wireless performance.

Who It's For

This board targets small-form-factor builders who want a true flagship CPU in an ITX footprint: gamers who value low-latency 3D V-Cache gains, streamers needing many threads, and creators who want fast PCIe 5.0 storage and DDR5 bandwidth. It is also suited to those who prioritize energy efficiency while retaining performance, as the board delivers high throughput with relatively low power draw.

Not ideal for users who require many legacy ports or internal drive bays, since the design emphasizes M.2 storage and does not provide multiple SATA connectors. Also, those seeking the widest possible BIOS customization may find the firmware less flexible according to some user feedback.

Pros & Cons

Pros

• Exceptional multi-core performance from the integrated Ryzen 9 7945HX3D for gaming and productivity.
• Large 144MB cache and 3D V-Cache provide improved gaming frame stability and responsiveness.
• Dual PCIe 5.0 M.2 and DDR5 support enable very fast storage and memory configurations for future upgrades.
• Efficient cooling layout keeps the board quiet and stable under sustained loads.

Cons

• Limited legacy storage options, with few or no SATA ports noted by users, which may complicate some builds.
• BIOS options receive some criticism for being limited compared with enthusiast motherboards.
