ASRock AMD B850i Lightning WiFi 6E Socket AM5 vs ASUS ROG Crosshair X870E Dark Hero ATX

Design and Form Factor

The ASRock AMD B850i Lightning is designed as a Mini-ITX motherboard, while the ASUS ROG Crosshair X870E Dark Hero is an ATX motherboard. This fundamental difference affects compatibility and build options. The compact design of the ASRock motherboard (170x170mm) makes it ideal for small form factor builds, allowing users to save space without compromising on functionality. On the other hand, the ASUS motherboard provides a larger surface area, accommodating more components and offering greater expandability.

With a Mini-ITX form factor, the ASRock model is perfect for users looking to build compact gaming rigs or home theater PCs, but it does require careful selection of case and cooling solutions. The ASUS ATX motherboard, by contrast, is geared towards those who want to maximize their build with additional features and connectivity options.

Power Delivery and Overclocking

The ASRock AMD B850i Lightning features a 10+1+1 phase power design, while the ASUS ROG Crosshair X870E Dark Hero boasts a robust 20+2+2 power stage configuration. This significant difference in power delivery means that the ASUS motherboard is better equipped for overclocking, providing the necessary stability and performance for high-demand applications.

Given the advanced power solutions in the ASUS motherboard, it is particularly well-suited for users who intend to push their Ryzen processors to the limit. The ASRock, while still capable, may not handle extreme overclocking scenarios as effectively, making it more suitable for moderate users.

Memory Support

When it comes to memory support, the ASRock AMD B850i Lightning can handle up to 128GB of DDR5 RAM at speeds of 8200+ MHz (OC). In contrast, the ASUS ROG Crosshair X870E Dark Hero also supports DDR5 memory but does not specify maximum speeds or capacity. However, it features a more robust memory layout with multiple slots, enhancing its capability for memory-intensive tasks.

The ability of the ASRock board to support extreme memory speeds is a notable advantage for enthusiasts who prioritize high-performance gaming or content creation. In comparison, users who need more memory slots for extensive multitasking or larger capacity would find the ASUS model more appealing.

Storage Options

The ASRock AMD B850i Lightning provides dual ultra-fast storage capabilities with its Blazing M.2 (PCIe Gen5x4) and Hyper M.2 (PCIe Gen4x4) slots. Meanwhile, the ASUS ROG Crosshair X870E Dark Hero offers a more extensive storage solution with five M.2 slots, including two PCIe 5.0 slots and three PCIe 4.0 slots.

For users looking to maximize storage performance and flexibility, the ASUS motherboard clearly outshines its competitor. The increased number of slots allows for more SSD installations and better performance scaling, which is essential for high-end gaming and data-intensive applications.

Networking Features

Both motherboards excel in networking capabilities, but they cater to different needs. The ASRock AMD B850i Lightning features Killer 2.5G LAN and WiFi 6E with Bluetooth, providing an excellent balance of wired and wireless connectivity. Conversely, the ASUS ROG Crosshair X870E Dark Hero steps it up with onboard Wi-Fi 7 (802.11be), along with Realtek 10Gb Ethernet and 5Gb Ethernet options.

The ASUS motherboard, with its advanced Wi-Fi 7 technology, promises faster wireless speeds and improved connectivity, making it ideal for users who prioritize cutting-edge networking. The ASRock board, while still robust, may not offer the same level of future-proofing or performance in high-demand network scenarios.

Audio Quality

The audio capabilities of these motherboards differ significantly. The ASRock AMD B850i Lightning lacks specific audio details in its features, while the ASUS ROG Crosshair X870E Dark Hero is equipped with the ROG SupremeFX ALC4082 codec and ESS ES9219 Quad DAC for high-quality audio playback up to 32-Bit/384 kHz.

For audiophiles or gamers who value immersive sound, the ASUS motherboard clearly has the upper hand, offering superior audio components designed for high-fidelity sound reproduction. The absence of explicit audio features in the ASRock board suggests it may not cater to users who prioritize audio quality as much as other aspects.

Price Comparison

The ASRock AMD B850i Lightning is priced at $179.99, making it about 74% cheaper than the ASUS ROG Crosshair X870E Dark Hero, which retails for $699.99. This substantial price difference reflects the target markets for each motherboard.

The ASRock model is a budget-friendly option for casual users or those building compact systems, while the ASUS model is designed for enthusiasts who demand high performance and advanced features, justifying its higher price point.

Which should you buy?

Choosing between the ASRock AMD B850i Lightning and the ASUS ROG Crosshair X870E Dark Hero ultimately depends on your specific needs and budget. If you’re looking for a compact, affordable option with solid performance for everyday tasks, the ASRock motherboard is an excellent choice. However, if you’re an enthusiast seeking advanced features, superior power delivery, extensive connectivity options, and high-quality audio, the ASUS motherboard is the clear winner despite its higher price. Consider your priorities for power, expandability, and budget to make the best decision for your build.
