ASRock AMD B850i Lightning WiFi 6E Socket AM5 vs ASRock B850M-X WiFi R2.0 AM5 Micro-ATX

Overview of Both Motherboards

The ASRock AMD B850i Lightning WiFi 6E and the ASRock B850M-X WiFi R2.0 are both excellent choices for users looking to build a system with AMD Ryzen processors. The B850i Lightning is priced at $179.99, while the B850M-X is about 28% cheaper at $129.99. Both motherboards support AMD Ryzen 9000, 8000, and 7000 Series processors, but they cater to different form factors and user needs.

The B850i Lightning is a Mini-ITX motherboard designed for compact builds, while the B850M-X is a Micro-ATX motherboard that provides more expandability. Depending on your specific requirements, one of these motherboards may serve you better than the other.

Form Factor and Size

The ASRock B850i Lightning features a Mini-ITX form factor, measuring 170x170mm, making it ideal for small form factor builds. This compact design allows users to create sleek, space-saving systems. In contrast, the B850M-X is a Micro-ATX motherboard, which is larger and provides more room for additional components.

The Mini-ITX design of the B850i Lightning caters to enthusiasts who want a streamlined setup, while the B850M-X offers greater flexibility for users who may want to include more hardware, such as additional graphics cards or storage drives. If space is a premium for you, the B850i Lightning may be the better option.

Power Delivery and Stability

When it comes to power delivery, the ASRock B850i Lightning boasts a premium 10+1+1 phase power design with a 110A Smart Power Stage. This robust power delivery system ensures stable performance, particularly during overclocking scenarios. On the other hand, the B850M-X features a 6+1+1 phase power design with Dr.MOS for VCore, which is competent but less powerful than that of the B850i.

For users looking to push their systems to the limit, the B850i Lightning’s superior power phase design provides a more stable environment for overclocking, making it the better choice for performance-oriented builds.

Memory Support and Compatibility

Both motherboards support DDR5 memory with speeds up to 8200+ (OC) MHz, providing ample bandwidth for demanding applications and gaming. The B850i Lightning has two DDR5 DIMM slots supporting dual-channel configurations, while the B850M-X also features two DIMM slots with similar support.

Given that both options offer the same memory capabilities, your choice may hinge more on other features rather than memory support alone. However, the B850i Lightning's Mini-ITX form factor might limit your future upgrade options compared to the more versatile B850M-X.

Expansion Slots and Connectivity

The ASRock B850i Lightning includes one PCIe 5.0 x16 slot, which is ideal for the latest graphics cards, and features dual M.2 slots for high-speed storage options. Conversely, the B850M-X provides one PCIe 5.0 x16 slot along with one PCIe 4.0 x16 and one PCIe 4.0 x1 slot, which offers more flexibility for adding multiple cards.

Both motherboards also feature advanced networking capabilities, with Wi-Fi 6E and Bluetooth, ensuring fast wireless connectivity. If you plan to add multiple expansion cards, the B850M-X may be the more suitable option.

Storage Options

For storage, the ASRock B850i Lightning includes both a Blazing M.2 slot (PCIe Gen5x4) and a Hyper M.2 slot (PCIe Gen4x4), ensuring you have the latest technology for high-speed storage. The B850M-X also features a Blazing M.2 slot alongside a Hyper M.2 slot, giving it competitive storage capabilities.

Both motherboards support a good range of SATA connections, but the B850i Lightning’s additional PCIe 5.0 support may provide faster overall performance for gamers and professionals who require top-tier storage solutions.

Audio Features

The audio capabilities of the ASRock B850i Lightning and B850M-X are comparable, with both boards supporting high-definition audio codecs. The B850M-X features the Realtek ALC897 7.1 channel HD audio codec, while the B850i Lightning does not specify its audio codec but is designed for high-quality sound output.

While both motherboards are capable of delivering excellent audio experiences, the B850M-X explicitly highlights its audio features, making it a more appealing option for users who prioritize sound quality in their builds.

Which should you buy?

Ultimately, your choice between the ASRock B850i Lightning and the ASRock B850M-X will depend on your specific needs and preferences. If you are looking for a compact Mini-ITX motherboard with superior power delivery and storage capabilities, the B850i Lightning at $179.99 may be the better option. However, if you require a more affordable Micro-ATX motherboard with greater expansion potential and flexibility, the B850M-X, priced at $129.99, is an excellent choice.

Both motherboards are well-suited for AMD Ryzen processors, but your decision should align with your build goals, whether that's compactness or expandability.
