GIGABYTE B650 Eagle AX AM5 LGA 1718 AMD B650 ATX vs GIGABYTE Z790 UD AC LGA 1700 ATX Motherboard,

Overview

The GIGABYTE B650 Eagle AX and GIGABYTE Z790 UD AC are two powerful ATX motherboards designed for high-performance computing. The B650 Eagle AX is priced at $139.99, making it about 17% cheaper than the Z790 UD AC, which costs $149.99. Both motherboards offer excellent features, but they cater to different processor families and performance needs.

Socket Compatibility

The B650 Eagle AX supports AMD's AM5 socket, which is designed for the Ryzen 7000 Series processors. In contrast, the Z790 UD AC is compatible with Intel's LGA 1700 socket, supporting 14th, 13th, and 12th Gen Intel Core processors. This distinction is crucial for users looking to build a system specific to their preferred CPU brand. Depending on your choice of processor, one motherboard will be more suitable than the other.

Memory Support

Both motherboards are DDR5 compatible, allowing for faster data transfer rates compared to older DDR4 memory. The B650 Eagle AX features four SMD DIMMs with support for AMD EXPO and Intel XMP memory modules. Meanwhile, the Z790 UD AC also supports dual-channel DDR5 with four DIMMs. This means that both motherboards can effectively leverage high-speed memory, but users should consider their specific use cases when selecting RAM.

Power Design

The power design of a motherboard is vital for system stability and performance. The B650 Eagle AX boasts a 12 plus 2 plus 2 Phases Digital VRM Solution, ensuring stability during high-load conditions. In comparison, the Z790 UD AC features a more robust 16 plus 1 plus 1 Twin Hybrid Phases Digital Power Design, which includes 60A DrMOS. This indicates that the Z790 UD AC may offer slightly better performance under extreme workloads, appealing to users who prioritize overclocking and demanding applications.

Thermal Management

Effective thermal management is essential for maintaining performance and longevity in high-performance systems. The B650 Eagle AX includes advanced thermal design features such as an M.2 Thermal Guard to ensure stable performance of SSDs. On the other hand, the Z790 UD AC incorporates fully covered MOSFET heatsinks, M.2 Thermal Guard, and Ultra Durable Armor, making it potentially more effective at managing heat under heavy loads. Gamers and content creators who push their systems to the limits may find the Z790’s cooling solutions advantageous.

Connectivity Options

Connectivity is another crucial aspect to consider when choosing a motherboard. The B650 Eagle AX offers stable connectivity with one PCIe 5.0 M.2 slot and two PCIe 4.0 M.2 slots, along with USB 3.2 Gen 2x2 Type-C. The Z790 UD AC steps it up with three M.2 slots, all supporting PCIe 4.0 x4, and also features SuperSpeed USB 3.2 Gen 2x2 Type-C. For users who require extensive storage options and high-speed data transfer, the Z790 UD AC provides a more versatile connectivity solution.

Networking Features

Networking capabilities can significantly influence the overall performance of a system, especially in gaming and streaming. The B650 Eagle AX is equipped with AMD Wi-Fi 6E and Realtek GbE LAN, offering solid wireless and wired connectivity. In contrast, the Z790 UD AC features dual-band WiFi and 2.5GbE LAN, providing faster wired networking and improved wireless performance. For users who prioritize online gaming or high-bandwidth applications, the Z790 UD AC may be the preferable choice.

Price and Value

When it comes to price, the B650 Eagle AX is currently available for $139.99, whereas the Z790 UD AC is priced at $149.99. This $10 difference represents about a 7% premium for the Z790 UD AC. Given the feature set of both motherboards, users must consider whether the additional capabilities of the Z790 justify the higher price. If the features align with your performance needs, the investment may be worth it; otherwise, the B650 Eagle AX offers substantial value for users focused on AMD platforms.

Which should you buy?

Choosing between the GIGABYTE B650 Eagle AX and GIGABYTE Z790 UD AC ultimately depends on your specific needs. If you are committed to AMD processors and are looking for a budget-friendly option, the B650 Eagle AX is a strong contender with solid features for its price. Conversely, if you prefer Intel processors and seek advanced power design, superior thermal management, and enhanced connectivity options, the Z790 UD AC justifies its higher price. Consider your processor choice, desired features, and budget to determine which motherboard best suits your setup.
