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

Overview of the ASRock AMD B850i Lightning and GIGABYTE Z790 UD AC

The ASRock AMD B850i Lightning is priced at $179.99, while the GIGABYTE Z790 UD AC is about 17% cheaper at $149.99. Both motherboards cater to high-performance computing but target different processor families and use cases. The ASRock model supports AMD Ryzen processors, while the GIGABYTE is designed for Intel Core processors across multiple generations. Understanding these differences can help users make informed decisions based on their specific needs.

Form Factor and Design

The ASRock B850i Lightning features a Mini-ITX form factor, making it ideal for compact builds, measuring just 170x170mm. In contrast, the GIGABYTE Z790 UD AC adopts an ATX design, which provides more expansion options and is better suited for larger cases. The choice between these two designs largely depends on the user's build preferences and space constraints. If you prioritize a smaller footprint, the ASRock is the clear choice, whereas the GIGABYTE offers more room for additional components.

Power Delivery and Stability

Power delivery systems vary significantly between the two motherboards. The ASRock B850i Lightning boasts a 10+1+1 phase power design with a robust 110A Smart Power Stage, ensuring stable performance for high-demand applications. In comparison, the GIGABYTE Z790 UD AC comes with a 16+1+1 Twin Hybrid Phases Digital Power Design featuring 60A DrMOS, which is also designed to deliver stable power to Intel processors. Both motherboards provide premium power delivery, but the GIGABYTE's design may offer slightly better performance under peak loads due to its higher phase count.

Memory Support and Performance

The ASRock B850i Lightning supports dual-channel DDR5 memory with two DIMM slots, allowing for extreme overclocked speeds up to 8200+ MHz. This high-speed memory support is perfect for gamers and content creators seeking maximum performance. On the other hand, the GIGABYTE Z790 UD AC can accommodate up to four DDR5 DIMMs, providing greater flexibility for memory expansion. Both boards support the latest DDR5 technology, but the ASRock has a distinct advantage in terms of extreme speeds, whereas the GIGABYTE offers more capacity potential.

Connectivity Options

Connectivity features are essential for modern builds, and both motherboards excel in this area. The ASRock B850i Lightning includes PCIe 5.0 support with one x16 slot, ensuring compatibility with next-generation graphics cards. It also features Killer 2.5G LAN and WiFi 6E for superior networking capabilities. Conversely, the GIGABYTE Z790 UD AC supports PCIe 5.0 as well, but it offers triple M.2 slots for NVMe storage, enhancing storage flexibility. Both motherboards provide high-speed USB options, including USB 3.2 Gen2 Type-C ports, but the choice may depend on specific connectivity needs.

Storage Solutions

For storage solutions, the ASRock B850i Lightning features two M.2 slots, one optimized for PCIe Gen5 and the other for PCIe Gen4, delivering excellent performance for SSDs. The GIGABYTE Z790 UD AC, however, offers three M.2 slots, providing greater versatility for users looking to expand their storage options. Both motherboards ensure high-speed data transfer, but if you require multiple NVMe drives, the GIGABYTE is the better option due to its additional slots.

Networking Capabilities

Networking is another area where both motherboards shine, though they target slightly different needs. The ASRock B850i Lightning offers advanced networking with Killer 2.5G LAN and WiFi 6E, making it an excellent choice for gamers who demand low latency and high-speed connections. The GIGABYTE Z790 UD AC also includes dual-band WiFi and 2.5GbE, ensuring solid performance for online gaming and streaming. Both options are robust, but the ASRock may appeal more to users prioritizing cutting-edge wireless technology.

Price Comparison

The ASRock B850i Lightning is priced at $179.99, while the GIGABYTE Z790 UD AC is priced at $149.99. This makes the GIGABYTE about 17% cheaper than the ASRock, which could be a deciding factor for budget-conscious consumers. Despite the price difference, both boards offer excellent features tailored to different processor families. The value proposition will depend on whether the user prefers AMD or Intel processors and their specific needs for features like memory speed and storage options.

Which should you buy?

Choosing between the ASRock B850i Lightning and the GIGABYTE Z790 UD AC primarily depends on your processor preference and specific build requirements. If you're building a compact system with an AMD Ryzen processor and need top-tier memory speeds, the ASRock is the better choice. However, if you prefer Intel processors and require more expansion capabilities and storage options, the GIGABYTE offers excellent value and performance at a lower price point. Ultimately, both motherboards are excellent in their own right, catering to distinct user needs and preferences.
