Overview of the ASRock AMD B850i Lightning and MSI PRO Z790-A MAX
The ASRock AMD B850i Lightning is priced at $179.99, while the MSI PRO Z790-A MAX comes in at $279.77, making the ASRock about 36% cheaper. Both motherboards cater to different processor families and come with distinct features that will appeal to varied user needs. The ASRock targets AMD Ryzen processors, while the MSI supports Intel’s 12th, 13th, and even 14th generation CPUs, showcasing a significant divergence in target audience and compatibility.
Design and Form Factor
The ASRock AMD B850i Lightning boasts a compact Mini-ITX design measuring 170x170mm, which is ideal for small form factor builds. This makes it perfect for users looking to save space without sacrificing performance. In contrast, the MSI PRO Z790-A MAX follows a traditional ATX form factor, which provides more room for additional components and better airflow. While the ASRock is designed for compact builds, the MSI is aimed at users who prefer a larger chassis with more expansion options.
Power Delivery and Performance
The ASRock features a 10+1+1 phase power design with a 110A Smart Power Stage, ensuring stable performance for AMD Ryzen processors. This is particularly beneficial for users looking to overclock, as it provides a solid foundation for enhanced performance. On the other hand, the MSI PRO Z790-A MAX offers a more robust 16+1+1 design with an 80A Smart Power Stage and dual 8-pin CPU power connectors. This enhanced power delivery system is particularly suited for high-performance Intel processors, making it a great choice for gamers and professionals.
Memory Support
When it comes to memory support, the ASRock AMD B850i Lightning can accommodate dual-channel DDR5 memory with speeds up to 8200+ MHz (OC), making it an excellent option for those who want to push the limits of their system. The MSI PRO Z790-A MAX also supports DDR5 memory, with speeds reaching up to 7800+ MHz (OC). Both motherboards support the latest memory technology, but the ASRock has a slight edge in terms of maximum overclocked speeds.
Storage Options
The ASRock provides dual high-speed storage options with its Blazing M.2 (PCIe Gen5x4) and Hyper M.2 (PCIe Gen4x4) slots, allowing for maximum storage performance in compact builds. This is a significant advantage for users who need quick access to data and game loading times. Conversely, while the MSI PRO Z790-A MAX includes M.2 support, it does not specify the same level of performance as the ASRock. Nevertheless, it still offers SATA 6G support, providing flexibility for traditional storage solutions.
Networking and Connectivity
In terms of networking, the ASRock AMD B850i Lightning features Killer 2.5G LAN and WiFi 6E, ensuring premium wired and wireless connectivity for a seamless online experience. The inclusion of Bluetooth further enhances its connectivity options. Meanwhile, the MSI PRO Z790-A MAX is equipped with WiFi 7 and Bluetooth 5.4, which are the latest standards, promising faster speeds and better range. For users focused on high-speed internet and connectivity, the MSI motherboard may have the edge.
Aesthetics and Build Quality
The ASRock motherboard sports a compact and practical design tailored for small builds, while the MSI PRO Z790-A MAX features a harmonious silver color scheme that complements both black and white PC builds. The MSI also touts a high-quality PCB made with server-grade materials, emphasizing durability and reliability. This difference in aesthetics may appeal to users who prioritize the visual aspects of their builds alongside performance.
Which should you buy?
Choosing between the ASRock AMD B850i Lightning and the MSI PRO Z790-A MAX largely depends on your specific needs and preferences. If you are building a compact system centered around AMD Ryzen processors and want high maximum memory speeds at a lower price point, the ASRock is an exceptional choice at $179.99. On the other hand, if you prefer Intel processors and seek the latest connectivity options with a larger form factor, the MSI, despite its higher price of $279.77, offers compelling features that justify its cost. Ultimately, your decision should align with your processor choice and system requirements.
