ASRock AMD B850i Lightning WiFi 6E Socket AM5 vs ASRock B450M/AC R2.0 AM4 AMD Promontory B450 SATA

Overview of the Products

In this comparison, we examine the ASRock AMD B850i Lightning WiFi 6E and the ASRock B450M/AC R2.0. The former offers cutting-edge features for high-performance builds while the latter is a budget-friendly option for users with less demanding requirements. The B850i is priced at $179.99, whereas the B450M is significantly cheaper at $79.00, making it about 56% less expensive.

Design and Form Factor

The ASRock AMD B850i Lightning WiFi 6E features a Mini-ITX form factor, measuring 170x170mm, which is ideal for compact builds. This is particularly beneficial for users looking to create small form factor PCs without sacrificing performance. On the other hand, the ASRock B450M/AC R2.0 is a Micro ATX motherboard, providing a bit more room for additional components and expansion options. The choice between these designs will depend largely on the user's case size and intended use.

Performance and Compatibility

The ASRock AMD B850i Lightning WiFi 6E supports AMD Ryzen 9000, 8000, and 7000 series processors, providing a future-proof option for high-performance computing. In contrast, the ASRock B450M/AC R2.0 is compatible with AMD Ryzen 2000, 3000, 4000 G-Series, and 5000 series processors. While the B450M offers decent performance for mid-range builds, the B850i's compatibility with newer processors allows for superior performance, particularly in gaming and demanding applications.

Memory and Storage Options

When it comes to memory, the ASRock AMD B850i Lightning WiFi 6E boasts two DDR5 DIMM slots that support extreme overclocked speeds up to 8200+ MHz. This high-speed memory support is crucial for users looking to push their systems to the limit. The B450M/AC R2.0, however, supports DDR4 memory up to 3200 MHz, which is adequate for most standard applications but may not meet the needs of performance enthusiasts. Additionally, the B850i features dual ultra-fast storage options with both PCIe Gen5x4 and PCIe Gen4x4 slots, offering significantly faster data transfer speeds than the B450M's SATA 6Gb/s connections.

Connectivity Features

Connectivity is another area where the ASRock AMD B850i Lightning WiFi 6E shines. It includes advanced networking capabilities with Killer 2.5G LAN and WiFi 6E, providing excellent wired and wireless performance. Furthermore, it features multiple USB 3.2 Gen2 ports, including a Type-C port that can achieve speeds up to 40Gb/s. The ASRock B450M/AC R2.0, while functional, offers standard HDMI graphics output and lacks the higher-speed connectivity options present in the B850i. This makes the B850i a better choice for users who rely heavily on fast networking and data transfer.

Power Delivery and Efficiency

The ASRock AMD B850i Lightning WiFi 6E is designed with a premium 10+1+1 phase power delivery system, which ensures stable performance even in compact builds. This feature is particularly important for users who plan to overclock their CPUs. In contrast, the B450M/AC R2.0 does not provide specific details about its power delivery system, which may not be as robust. For users seeking efficiency and stability during high-demand tasks, the B850i is the superior choice.

Price and Value

The ASRock B450M/AC R2.0 is priced at $79.00, making it an attractive option for budget-conscious consumers. In comparison, the ASRock AMD B850i Lightning WiFi 6E is priced at $179.99, which is about $100 more. While the B450M offers great value for basic computing needs, the B850i justifies its higher price with advanced features and support for modern hardware, making it a worthwhile investment for serious gamers and content creators.

User Support and Resources

Both products come from ASRock, a reputable brand in the motherboard market. The ASRock AMD B850i Lightning WiFi 6E emphasizes dedicated customer support directly through Amazon, which is beneficial for users who might have questions or require assistance. The B450M/AC R2.0 does not highlight this feature, which may be a consideration for less experienced users. Thus, the B850i offers an edge in terms of customer service and support.

Which should you buy?

Choosing between the ASRock AMD B850i Lightning WiFi 6E and the ASRock B450M/AC R2.0 boils down to your specific needs and budget. If you are building a high-performance PC and require the latest technology, the B850i is the clear winner with its superior memory speeds, advanced connectivity, and robust power delivery. However, if you are on a tighter budget and your computing needs are more basic, the B450M offers solid performance at a significantly lower price point. Ultimately, your decision should align with your performance expectations and financial considerations.
