The Gigabyte A520I AC is priced at $99.99, while the MSI A520M-A PRO Gaming Motherboard is significantly cheaper at $68.99, making it about 31% less expensive. Both motherboards are designed for AMD Ryzen processors, but they offer different features and capabilities that cater to various user needs.
The Gigabyte A520I AC is a Mini-ITX motherboard, ideal for compact builds, while the MSI A520M-A PRO is a Micro-ATX motherboard, providing a larger form factor that can accommodate additional components. Users should consider their specific requirements, such as size constraints and desired features, when choosing between these two options.
Compatibility with Processors
Both motherboards support 3rd Gen AMD Ryzen processors and cater to the AM4 socket type, making them versatile choices for users looking to build or upgrade their systems. The Gigabyte A520I AC explicitly supports the latest generation of AMD Ryzen processors, ensuring compatibility with the latest technologies.
In contrast, the MSI A520M-A PRO Gaming Motherboard also supports AMD Ryzen 4000 G-Series processors, providing additional flexibility for users who may choose to utilize these CPUs. This broader compatibility makes the MSI board a compelling option for users who want more choices in processor selection.
Memory Support
The memory specifications differ slightly between the two motherboards. The Gigabyte A520I AC supports Dual Channel DDR4 memory with two DIMM slots, allowing for efficient memory usage and decent performance. However, it doesn't specify a maximum memory speed.
The MSI A520M-A PRO, on the other hand, supports DDR4 memory up to 4600(OC) MHz, which is significantly higher than most consumer-grade motherboards. This feature provides users with the opportunity to maximize their system's memory performance, especially for gaming and intensive applications. This higher memory speed capability gives the MSI motherboard an edge in terms of memory performance.
Expansion Capabilities
When it comes to expansion options, the Gigabyte A520I AC features a PCIe 3.0 x16 slot and one NVMe PCIe 3.0 x4 M.2 slot. This configuration allows for decent upgrade potential, especially for users looking to add high-speed storage solutions.
In comparison, the MSI A520M-A PRO offers a Turbo M.2 slot that runs at PCI-E Gen3 x4, enhancing performance for NVMe-based SSDs. Both motherboards provide solid expansion options, but the MSI’s Turbo M.2 feature could lead to better performance for users who prioritize storage speed in their builds.
Audio Quality
Audio performance is an essential aspect for many users, especially gamers and content creators. The Gigabyte A520I AC uses the ALC887 audio codec, which offers a reliable audio experience suitable for most applications.
The MSI A520M-A PRO offers an Audio Boost feature, promising studio-grade sound quality. This could be particularly beneficial for users who value high-fidelity audio capabilities. If sound quality is a deciding factor, the MSI motherboard may be the better choice due to its enhanced audio features.
Networking Features
Networking capabilities also differ between the two motherboards. The Gigabyte A520I AC boasts a blazing-fast 1GbE LAN connection, along with Intel Dual Band AC WiFi and Bluetooth support, making it an excellent choice for users who need reliable wireless connectivity.
Conversely, the MSI A520M-A PRO does not mention integrated WiFi or Bluetooth, which could be a disadvantage for users who require these features for wireless connectivity. For those who depend on high-speed internet access and wireless capabilities, the Gigabyte A520I AC clearly stands out.
Design and Aesthetics
In terms of design, the Gigabyte A520I AC is a Mini-ITX board with an optimized VRM heatsink, making it suitable for compact builds while maintaining efficient thermal performance. Its RGB FUSION 2.0 feature adds a touch of personalization for users who enjoy customizing their setups.
The MSI A520M-A PRO has a more traditional Micro-ATX layout, which may not have the same aesthetic appeal but allows for easy access to components and better airflow. While both motherboards have their unique designs, users who appreciate aesthetics may lean towards the Gigabyte board for its RGB features.
Which should you buy?
When choosing between the Gigabyte A520I AC and the MSI A520M-A PRO Gaming Motherboard, the decision largely hinges on your specific needs and budget. The MSI A520M-A PRO, priced at $68.99, is about 31% cheaper than the Gigabyte A520I AC, making it a more budget-friendly option. It also offers superior memory support and audio enhancements.
However, if you need a compact solution with superior networking features and aesthetic appeal, the Gigabyte A520I AC could be worth the extra investment. Ultimately, both motherboards have their strengths, and your choice should align with your unique requirements and preferences.
