GIGABYTE B650 Eagle AX AM5 LGA 1718 AMD B650 ATX Motherboard, DDR5, Triple M.2 (1x PCIe 5.0 M.2 + 2X PCIe 4.0 M.2), USB 3.2 Gen2x2 Type-C, AMD Wi-Fi 6E, Realtek GbE LAN vs SHANGZHAOYUAN B85M PRO LGA 1150 Motherboard for Intel 4th Gen Core i7 i5 i3/Pentium/Celeron Series Processors (Micro-ATX, DDR3, PCIe 3.0, NVME M.2, SATA 3.0, VGA/DVI/HDMI-Compatible, Gigabit LAN)

Socket Compatibility and Processor Support

The GIGABYTE B650 Eagle AX AM5 supports AMD Ryzen 7000 Series processors via the AM5 socket, while the SHANGZHAOYUAN B85M PRO is designed for Intel 4th Gen Core i7/i5/i3, Pentium, and Celeron CPUs using the LGA 1150 socket. This fundamental difference means the two motherboards are incompatible with each other’s processor families. The B650 Eagle AX enables users to leverage modern AMD platforms with future-proof AM5 architecture, whereas the B85M PRO targets older Intel systems from the 4th generation lineup. The price difference reflects this divide: the GIGABYTE model costs $139.99, nearly 75% more than the SHANGZHAOYUAN at $79.99.

Memory Support and Performance

The GIGABYTE B650 Eagle AX supports DDR5 memory across four DIMM slots with AMD EXPO and Intel XMP compatibility, enabling faster speeds and improved performance. In contrast, the SHANGZHAOYUAN B85M PRO uses dual-channel DDR3 memory with support up to 1333/1600/1866MHz and a maximum capacity of 32GB. While both offer multi-channel memory configurations, DDR5 on the GIGABYTE board provides significantly higher bandwidth and lower latency compared to DDR3. The B650 Eagle AX also features a 12+2+2 phase VRM design, which enhances power delivery stability under load—something absent in the SHANGZHAOYUAN’s 4-phase power supply. This makes the GIGABYTE board better suited for high-performance builds requiring consistent memory throughput.

Storage Interface and Expansion Capabilities

The GIGABYTE B650 Eagle AX includes three M.2 slots: one PCIe 5.0 M.2 and two PCIe 4.0 M.2, offering cutting-edge storage speeds and scalability. It also supports USB 3.2 Gen2x2 Type-C for fast external data transfer. The SHANGZHAOYUAN B85M PRO features a single M.2 slot that supports NVMe and SATA modes automatically, along with three SATA 3.0 ports. While it offers basic NVMe support, it lacks PCIe 5.0 and has no Type-C connectivity. The GIGABYTE motherboard’s triple M.2 configuration allows for RAID setups or dedicated OS drives, giving it a clear edge in storage flexibility and speed. The SHANGZHAOYUAN’s single M.2 slot limits expansion options for users seeking high-speed SSD arrays.

Connectivity and I/O Features

The GIGABYTE B650 Eagle AX delivers advanced connectivity with USB 3.2 Gen2x2 Type-C, AMD Wi-Fi 6E, and Realtek GbE LAN for high-speed wired networking. These features ensure low-latency internet access and rapid file transfers. The SHANGZHAOYUAN B85M PRO includes a standard RJ45 Gigabit LAN port but lacks Wi-Fi and Type-C support. Its I/O includes VGA, DVI, and HDMI-compatible outputs, allowing display connections through multiple interfaces. However, it does not include any USB Type-C ports or wireless capabilities. For users prioritizing modern peripherals and network performance, the GIGABYTE model offers superior I/O options, especially with its inclusion of Wi-Fi 6E and high-speed USB.

Power Delivery and Thermal Design

The GIGABYTE B650 Eagle AX features a 12+2+2 phase digital VRM solution with advanced thermal design and M.2 Thermal Guard to maintain stable power delivery and prevent throttling during sustained workloads. This robust power system supports high-end AMD processors effectively. The SHANGZHAOYUAN B85M PRO uses a simpler 4-phase power supply with all-solid-state capacitors and a 24+8 pin power interface, requiring at least a 500W PSU. While well-built for its class, it lacks the thermal protection and phase count needed for overclocking or heavy-duty use. The GIGABYTE’s enhanced VRM and cooling features make it far more suitable for demanding applications like gaming, content creation, or server tasks.

Form Factor and Physical Design

The GIGABYTE B650 Eagle AX is an ATX-sized motherboard, providing ample space for components, cooling solutions, and expansion cards. Its larger footprint allows for better airflow and easier cable management. The SHANGZHAOYUAN B85M PRO is Micro-ATX, which reduces size and fits smaller cases but limits expansion potential. Both boards come with an I/O shield, but the SHANGZHAOYUAN explicitly notes that the manual and CR2032 battery are not included in the package. The GIGABYTE board’s ATX form factor gives it greater compatibility with full-size cases and high-end cooling systems, making it ideal for desktops prioritizing build quality and future upgrades.

Which should you buy?

If you're building a modern system around an AMD Ryzen 7000 Series processor, the GIGABYTE B650 Eagle AX is the only viable choice—it supports AM5, DDR5, PCIe 5.0, and advanced connectivity like Wi-Fi 6E and USB 3.2 Gen2x2 Type-C. At $139.99, it’s about 75% more expensive than the SHANGZHAOYUAN B85M PRO, which sells for $79.99. However, this price gap reflects a generational leap in technology: the GIGABYTE board offers future-proofed hardware, superior power delivery, and next-gen storage and networking. The SHANGZHAOYUAN B85M PRO remains relevant only for legacy Intel 4th Gen systems where budget constraints outweigh performance needs. For new builds, the GIGABYTE B650 Eagle AX is the definitive upgrade—its features justify the cost for anyone seeking long-term reliability and peak performance.
