GIGABYTE Z790 Eagle AX LGA 1700 Intel Z790 ATX Motherboard with DDR5 vs ASUS Prime B650-PLUS WiFi AMD B650 AM5 Ryzen Desktop 9000 8000 & 7000 ATX Mother

Processor Compatibility and Socket Type

The GIGABYTE Z790 Eagle AX supports Intel 14th and 13th Gen Core processors with its LGA 1700 socket, while the ASUS Prime B650-PLUS WiFi is compatible with AMD Ryzen Desktop 7000, 8000, and 9000 series processors via the AM5 socket. The GIGABYTE board is tailored specifically for Intel’s latest generation CPUs, offering direct compatibility without additional BIOS updates. In contrast, the ASUS motherboard supports multiple AMD Ryzen generations but may require a BIOS update when used with Ryzen 8000 or 9000 series processors. This means users seeking the latest Intel CPUs will find the GIGABYTE Z790 Eagle AX ready out-of-the-box, while AMD users get broader, albeit slightly more complex, compatibility with the ASUS Prime B650-PLUS WiFi.

Memory Support and Expansion

Memory-wise, the GIGABYTE Z790 Eagle AX offers support for dual-channel DDR5 memory across four DIMM slots, focusing on the latest high-speed RAM standards. In comparison, while the ASUS Prime B650-PLUS WiFi’s precise memory type isn’t explicitly listed, the mention of ASUS OptiMem II technology suggests a design aimed at preserving signal integrity and improving memory overclocking performance. The GIGABYTE’s explicit DDR5 compatibility signals a forward-looking stance on memory technology, whereas ASUS appears to optimize for stability and overclocking, catering to enthusiasts looking to push their memory performance.

Power Delivery and Thermal Management

The GIGABYTE Z790 Eagle AX features a robust power design with a twin 12+1+1 phase digital VRM solution, which provides stable power for demanding Intel CPUs. It also boasts an advanced thermal design with enlarged MOSFET heatsinks and an M.2 thermal guard to protect critical components from overheating. Meanwhile, the ASUS Prime B650-PLUS WiFi offers comprehensive cooling with VRM, M.2, and PCH heatsinks, alongside hybrid fan headers and Fan Xpert 2+ software for fan control. While both motherboards prioritize thermal efficiency, GIGABYTE’s power delivery system with its specific phase count suggests a potentially stronger emphasis on delivering clean and consistent power.

Connectivity and Expansion Options

Connectivity is a strong point for both motherboards but with different focal areas. The GIGABYTE Z790 Eagle AX supports next-generation PCIe 5.0, NVMe M.2, and USB 3.2 Gen 2x2 Type-C, ensuring top-tier data transfer speeds and future-proof peripheral support. ASUS Prime B650-PLUS WiFi goes further in network and USB connectivity, featuring WiFi 6E, Realtek 2.5Gb Ethernet, USB 10Gbps Type-C, front USB 5Gbps Type-C, and even Thunderbolt 4 header support. This means ASUS is better suited for users who prioritize wireless networking and ultra-fast USB connectivity, while GIGABYTE appeals to those emphasizing PCIe 5.0 and USB 3.2 Gen 2x2 speeds.

BIOS and Software Features

The ASUS Prime B650-PLUS WiFi offers a notable BIOS FlashBack feature, allowing users to update the UEFI BIOS easily by dropping the BIOS file onto a FAT32 USB stick and pressing a button—even without a CPU or memory installed. This safety and convenience feature is ideal for users who want a straightforward BIOS update process. Conversely, the GIGABYTE Z790 Eagle AX does not specifically mention BIOS update features in the provided data. ASUS also incorporates Aura Sync RGB lighting with onboard headers for synchronizing RGB components, enhancing customization and aesthetics.

Price Comparison

The ASUS Prime B650-PLUS WiFi is priced at C$194.03, making it the more budget-friendly option compared to the GIGABYTE Z790 Eagle AX, which costs C$249.99. This C$55.96 price difference reflects the different platform focus, with ASUS offering advanced networking and USB options at a lower cost, while GIGABYTE charges a premium for Intel Z790 chipset features and DDR5 support. Buyers should weigh whether the extra cost for GIGABYTE’s Intel-centric design and DDR5 capability is justified for their needs.

Design and Form Factor

Both motherboards use the ATX form factor, providing ample expansion slots and compatibility with most mid-tower and full-tower cases. The GIGABYTE Z790 Eagle AX emphasises a sturdy power design and advanced thermal solutions with enlarged heatsinks, while the ASUS Prime B650-PLUS WiFi includes hybrid fan headers and comprehensive cooling with multiple heatsinks for VRM, M.2, and PCH. ASUS also adds Aura Sync RGB lighting for visual customization, which may appeal to users looking to enhance the aesthetics of their build. Functionally, both designs aim at high performance and cooling but with different feature emphases.

Which should you buy?

Choosing between the GIGABYTE Z790 Eagle AX and the ASUS Prime B650-PLUS WiFi depends primarily on your CPU platform preference and connectivity needs. If you are building with Intel 13th or 14th Gen processors and want DDR5 memory support coupled with a robust power delivery system, the GIGABYTE board at C$249.99 is the clear choice. However, if you prefer AMD Ryzen 7000, 8000, or 9000 series CPUs and value extensive connectivity options like WiFi 6E, 2.5Gb Ethernet, Thunderbolt 4 support, and a convenient BIOS FlashBack feature—all at a lower price of C$194.03—the ASUS Prime B650-PLUS WiFi is more compelling. Ultimately, your decision should align with your processor brand, connectivity priorities, and budget considerations.
