ASRock AMD B850i Lightning WiFi 6E Socket AM5 vs GIGABYTE Z790 Eagle AX LGA 1700 ATX Motherboard,

Overview of the ASRock AMD B850i Lightning and GIGABYTE Z790 Eagle AX

The ASRock AMD B850i Lightning WiFi 6E is priced at $179.99, while the GIGABYTE Z790 Eagle AX is slightly cheaper at $159.99, making it approximately 17% less expensive. Both motherboards offer advanced features catering to gamers and PC builders, but they are designed for different processor families, which can greatly influence your choice.

The ASRock motherboard supports AMD's Ryzen 9000, 8000, and 7000 series processors, whereas the GIGABYTE model is compatible with Intel's Core 14th, 13th, and 12th generation chips. This fundamental difference in compatibility is crucial depending on your preferred CPU brand and performance needs.

Form Factor and Design

The ASRock B850i Lightning features a Mini-ITX form factor, which is ideal for compact builds, measuring just 170x170mm. This makes it a great choice for those looking to save space without sacrificing performance. On the other hand, the GIGABYTE Z790 Eagle AX utilizes a larger ATX form factor, providing more room for additional components and better airflow.

If your build requires a compact design, the ASRock model is the clear winner. However, if you prefer a more spacious layout with the option to expand, the GIGABYTE motherboard would be more suitable. Your choice of chassis will significantly impact your overall system design.

Power Delivery and Stability

Power delivery is a critical aspect of motherboard performance, and both models excel in this area. The ASRock B850i Lightning boasts a 10+1+1 phase power design with a 110A Smart Power Stage (SPS), ensuring stable performance even when overclocking. In comparison, the GIGABYTE Z790 Eagle AX offers a robust 12+1+1 power phase configuration, which also supports efficient power distribution.

Both motherboards are designed for high performance, but the GIGABYTE's slightly higher power phase count may offer a minor edge in power stability under heavy loads. However, both options are well-optimized for their respective CPU families.

Memory Support

The ASRock B850i Lightning supports dual-channel configurations with two DDR5 DIMM slots, allowing for extreme overclocked speeds up to 8200+ MHz. This is particularly advantageous for users seeking high-speed memory performance. Conversely, the GIGABYTE Z790 Eagle AX provides four DIMM slots, supporting dual-channel DDR5 memory as well, but it does not specify maximum speeds as high as the ASRock model.

In terms of memory capacity, the ASRock provides up to 128GB, which is ample for most gaming and professional applications. If memory speed is your priority, the ASRock has the upper hand, but if you prefer more slots for flexibility in upgrading, the GIGABYTE might be the better option.

Connectivity Options

Connectivity is where both motherboards shine, albeit in different ways. The ASRock B850i Lightning includes advanced networking options with Killer 2.5G LAN and WiFi 6E, offering superior wired and wireless connectivity. It also features a USB 3.2 Gen2 Type-C port capable of 40Gb/s speeds with compatible processors.

On the other hand, the GIGABYTE Z790 Eagle AX also offers WiFi 6E and 2.5GbE Ethernet, along with USB 3.2 Gen 2x2 Type-C support. Both boards provide ample high-speed connectivity, making them excellent choices for gaming and data-intensive tasks.

If you need the fastest possible connections, both motherboards are equipped to deliver. However, the ASRock's focus on high-speed USB capabilities may appeal more to those who regularly transfer large files.

Storage Options

Storage is another critical factor when choosing a motherboard. The ASRock B850i Lightning excels with its dual ultra-fast storage options, including Blazing M.2 (PCIe Gen5x4) and Hyper M.2 (PCIe Gen4x4) slots, maximizing storage performance in a compact design. This makes it an excellent choice for users looking to utilize the latest storage technologies.

In contrast, the GIGABYTE Z790 Eagle AX provides three M.2 slots, supporting PCIe 4.0 NVMe drives. While it offers ample storage options, it does not match the cutting-edge PCIe Gen5 support of the ASRock motherboard.

For users prioritizing the latest storage technology, the ASRock B850i Lightning stands out. However, if you need more physical M.2 slots, the GIGABYTE could be more appealing.

Aesthetics and Customization

While both motherboards are functional, they also cater to aesthetic preferences. The ASRock B850i Lightning is designed with a sleek, modern look that fits well in compact builds, and it offers RGB lighting options for customization. The GIGABYTE Z790 Eagle AX also features RGB Fusion for aesthetic enhancements, alongside a sturdy build quality that appeals to gamers.

Ultimately, your choice may come down to personal preference in design. Both motherboards provide options for customization, but the implementation and overall aesthetic may sway your decision.

Which should you buy?

Deciding between the ASRock AMD B850i Lightning and the GIGABYTE Z790 Eagle AX ultimately depends on your specific needs and preferences. If you are building a compact system with an AMD Ryzen processor and prioritize high-speed memory and storage options, the ASRock model is an excellent choice at $179.99. However, if you prefer a larger ATX form factor, want more DIMM slots for memory expansion, and are looking to save some money at $159.99, the GIGABYTE Z790 Eagle AX is a great alternative. Each motherboard excels in its own right, catering to different user requirements and system designs.
