ASRock AMD B850i Lightning WiFi 6E Socket AM5 vs ASUS ROG Maximus Z890 Hero Intel® Z890 LGA 1851

Overview of the Motherboards

When comparing the ASRock AMD B850i Lightning and the ASUS ROG Maximus Z890 Hero, a clear distinction arises in their target audience and design philosophy. The ASRock is designed for compact builds with a Mini-ITX form factor, while the ASUS offers a robust solution for those seeking advanced features in an ATX layout. Priced at $179.99, the ASRock is about 50% cheaper than the ASUS model, which is priced at $357.16. This price difference sets the stage for examining their capabilities in detail.

Form Factor and Design

The ASRock AMD B850i Lightning boasts a Mini-ITX form factor measuring 170x170mm, making it an excellent choice for small form factor builds. This compact design allows users to create powerful systems without taking up much space. In contrast, the ASUS ROG Maximus Z890 Hero features a standard ATX layout, providing more room for expansion and connectivity. The larger design supports more components and advanced cooling solutions, which can be beneficial for gamers and professionals who require high performance.

Compatibility and Processors

The ASRock motherboard is compatible with AMD Ryzen 9000, 8000, and 7000 series processors, giving users a wide range of options for their builds. The ASUS ROG Maximus, on the other hand, is built for Intel's LGA 1851 socket, specifically designed for the latest Intel Core Ultra processors. This difference in processor compatibility is critical for users who have brand loyalty or specific performance needs from their CPU choice.

Memory and Overclocking

In terms of memory support, the ASRock AMD B850i Lightning features two DDR5 DIMM slots that can handle extreme overclocked speeds up to 8200+ MHz. Meanwhile, the ASUS ROG Maximus Z890 Hero also supports DDR5 memory but emphasizes advanced overclocking features through technologies like NitroPath DRAM and AI Overclocking. This makes the ASUS a more appealing choice for enthusiasts and gamers who want to push their systems to the limits, despite being priced at about 97% higher than the ASRock.

Connectivity Options

The connectivity options present on both motherboards reflect their intended use cases. The ASRock includes advanced networking features such as Killer 2.5G LAN and WiFi 6E, offering excellent wired and wireless performance. Conversely, the ASUS ROG Maximus Z890 Hero takes connectivity further with WiFi 7, Thunderbolt 4, and three PCIe 5.0 M.2 slots. This variety in connectivity ensures the ASUS can handle multiple high-speed devices and peripherals, making it suitable for intensive tasks and future-proofing against emerging technologies.

Power Delivery and Stability

Power delivery is crucial for maintaining system stability, especially in high-performance builds. The ASRock features a 10+1+1 phase power design with a 110A Smart Power Stage, which provides significant stability in compact systems. The ASUS ROG Maximus Z890 Hero, however, offers a more robust power solution with 22(110A)+2(90A)+1(90A)+2(80A) stages, ensuring that even the most demanding setups remain stable under pressure. This higher power stage count helps enhance performance, particularly in overclocking scenarios.

Additional Features

Both motherboards come with unique features aimed at enhancing user experience. The ASRock boasts dual ultra-fast storage options with M.2 slots for maximum performance, whereas the ASUS emphasizes its AI technologies, including AI Cooling and AI Networking, to optimize system performance effortlessly. These additional features can significantly impact the overall performance and usability of each motherboard, depending on user preference.

Which should you buy?

Deciding between the ASRock AMD B850i Lightning and the ASUS ROG Maximus Z890 Hero ultimately comes down to your specific needs and budget. If you're looking for a compact, cost-effective option that supports AMD processors, the ASRock is about 50% cheaper and offers solid performance for small builds. However, if you require advanced features, exceptional overclocking capabilities, and future-proof connectivity, the ASUS is worth the investment, despite its higher price tag.
