This price difference reflects the distinct target audiences and features of each motherboard. GIGABYTE's offering is designed for high-performance gaming with support for Intel's latest processors, while MSI's model caters to users looking for a reliable, budget-friendly option for AMD Ryzen processors.
Performance Capabilities
The GIGABYTE Z790 UD AC boasts impressive performance capabilities, supporting Intel Core processors from the 12th to the 14th generation, and utilizing DDR5 memory technology for enhanced speed and efficiency. In contrast, the MSI A520M-A PRO, while supporting AMD's 3rd Gen Ryzen processors, is limited to DDR4 memory, which may restrict its performance in comparison. This difference can significantly influence the choice for gamers and content creators looking for advanced processing power and speed.
Build Quality and Design
The GIGABYTE Z790 UD AC features a robust power design with a 16+1+1 Twin Hybrid Phases Digital Power Design, ensuring stable performance even under heavy loads. Additionally, it includes comprehensive thermal management features, such as fully covered MOSFET heatsinks and M.2 thermal guards. Meanwhile, the MSI A520M-A PRO emphasizes durability with high-quality assembly but lacks the advanced thermal solutions found in GIGABYTE's model. Users seeking longevity and stability in high-performance scenarios may favor the Z790 UD AC.
Connectivity Options
Connectivity is a strong point for the GIGABYTE Z790 UD AC, which includes PCIe 5.0 support, three M.2 slots, and SuperSpeed USB 3.2 Gen 2x2 Type-C. This allows for faster data transfer rates and more versatile storage options. In contrast, the MSI A520M-A PRO supports PCIe 3.0 and offers a single M.2 slot with Turbo M.2 capability, which, while functional, does not match the speed of its competitor. For users who prioritize cutting-edge connectivity, the GIGABYTE model is the clear winner.
Gaming Features
For gamers, the GIGABYTE Z790 UD AC provides advanced features designed to optimize gaming performance, such as its support for high-speed DDR5 memory and enhanced power phases that can deliver superior overclocking potential. In comparison, the MSI A520M-A PRO focuses on providing essential gaming features like Audio Boost for better sound quality but lacks the advanced capabilities of the Z790 UD AC.

GIGABYTE's Z790 UD AC includes user-friendly features such as Q-Flash for easy BIOS updates and RGB Fusion for customizable lighting. This enhances the overall user experience, especially for those who enjoy personalization. The MSI A520M-A PRO, on the other hand, introduces the Dragon Center, which integrates various MSI tools into a single interface, making it easier for users to manage system settings. However, the lack of advanced customization options may be a drawback for some users.
Price and Value for Money
The GIGABYTE Z790 UD AC is priced at $149.99, while the MSI A520M-A PRO is available for $68.99, making the latter a more budget-friendly option. This represents a price difference of approximately $81, which can be significant for users on a tight budget. However, the higher price of the GIGABYTE model reflects its advanced features and capabilities, making it a better investment for serious gamers or those requiring high performance.
