Dimension comparison
Price Comparison
When considering the price, the ASUS Prime B840-PLUS WiFi is significantly more affordable at C$153.44 compared to the GIGABYTE Z790 Eagle AX, which retails for C$249.99. This represents a difference of C$96.55, making the ASUS motherboard a more economically viable option for budget-conscious consumers. The substantial price gap may influence buyers looking for value, especially those who do not require the latest features offered by more expensive models.
Socket Compatibility
The ASUS Prime B840-PLUS WiFi supports the AMD AM5 socket, which is compatible with the latest AMD Ryzen 9000, 8000, and 7000 Series Desktop Processors. In contrast, the GIGABYTE Z790 Eagle AX utilises the Intel LGA 1700 socket, accommodating 13th and 14th Gen Intel Core Series Processors. This distinction is crucial for consumers who are either invested in one brand's ecosystem or planning to upgrade their CPU in the near future. Choosing a motherboard that aligns with your desired processor lineage is essential to ensure compatibility and performance.
Memory Support
When it comes to memory technology, the ASUS Prime B840-PLUS WiFi is equipped to handle DDR5 RAM, ensuring users can leverage the high-speed capabilities of this modern memory standard. The GIGABYTE Z790 Eagle AX also supports DDR5, with a dual-channel configuration featuring four DIMM slots for memory expansion. Both motherboards are well-suited for high-performance builds, but the choice may come down to the motherboard's overall compatibility with other components.
Power Delivery and Design
The ASUS Prime B840-PLUS WiFi boasts an enhanced power solution with a 6-layer PCB, alloy chokes, and durable capacitors aimed at providing stable power delivery. Meanwhile, the GIGABYTE Z790 Eagle AX features a twin 12+1+1 phases digital VRM solution, which is designed to ensure robust power management for its supported processors. Both motherboards offer solid power delivery systems, but the GIGABYTE's more intricate phase design may appeal to those planning to push their CPUs to higher performance levels, particularly in overclocking scenarios.
Connectivity Options
Connectivity is a strong suit for both motherboards, but they cater to different needs. The ASUS Prime B840-PLUS WiFi comes with Wi-Fi 6E, a PCIe 4.0 x16 slot, and several PCIe 4.0 M.2 slots, allowing for a variety of fast data transfer options. It also includes Realtek 2.5Gb Ethernet and USB 10Gbps Type-A and Type-C ports. Conversely, the GIGABYTE Z790 Eagle AX offers PCIe 5.0, NVMe M.2, and USB 3.2 Gen 2x2 Type-C, which are designed for the latest connectivity standards. Users needing cutting-edge performance in their data transfer will find the GIGABYTE motherboard more appealing.
Thermal Management
Thermal management differs notably between the two motherboards. The ASUS Prime B840-PLUS WiFi incorporates comprehensive cooling solutions, including VRM and M.2 heatsinks, a PCH heatsink, and hybrid fan headers. This setup is beneficial for maintaining optimal operating temperatures during heavy workloads. The GIGABYTE Z790 Eagle AX also emphasizes thermal design, featuring an advanced thermal solution with enlarged MOSFET heatsinks and an M.2 thermal guard. While both boards appear well-equipped to handle heat dissipation, the GIGABYTE’s specific focus on MOSFET cooling may offer an edge in high-performance scenarios.
Personalization Features
In terms of personalization, the ASUS Prime B840-PLUS WiFi stands out with its three addressable Gen 2 headers compatible with ASUS-exclusive Aura Sync RGB lighting. This feature allows users to easily customise the aesthetics of their builds. The GIGABYTE Z790 Eagle AX does not highlight any specific personalization features in its specifications, which may limit options for users who value visual customisation in their setups. For those who enjoy tailoring their PC's appearance, the ASUS motherboard has a clear advantage.
Which should you buy?
Choosing between the ASUS Prime B840-PLUS WiFi and the GIGABYTE Z790 Eagle AX ultimately depends on your specific needs and budget. The ASUS motherboard offers a lower price point of C$153.44, making it an attractive option for those focused on affordability without sacrificing essential features. It excels in personalisation and connectivity while supporting the latest AMD processors. On the other hand, the GIGABYTE Z790 Eagle AX, priced at C$249.99, caters to users who require the latest technology, such as PCIe 5.0 and robust thermal management for high-performance builds. Therefore, if you're looking for value and compatibility with AMD processors, the ASUS is the way to go, while the GIGABYTE is ideal for users seeking cutting-edge Intel performance.
