ASRock B450M/AC R2.0 AM4 AMD Promontory B450 SATA vs ASRock B650I Lightning WiFi AMD AM5 Mini-ITX Motherboard

Introduction to the ASRock Motherboards

In the world of PC building, choosing the right motherboard is crucial for performance and compatibility. In this comparison, we will look at two distinct motherboards from ASRock: the ASRock B450M/AC R2.0 and the ASRock B650I Lightning WiFi. Each caters to different user needs and preferences, showcasing varied features and price points.

Pricing Overview

The ASRock B450M/AC R2.0 is priced at $79.00, while the ASRock B650I Lightning WiFi comes in at $169.99. This makes the B450M/AC R2.0 about 53% cheaper than its counterpart. The significant difference in price reflects the different technologies and target audiences of each motherboard, with the B450M targeting budget-conscious gamers and builders, and the B650I catering to those looking for cutting-edge features and future-proofing.

Form Factor and Design

The ASRock B450M/AC R2.0 is designed as a Micro ATX motherboard, making it suitable for standard builds that require a balance between size and expandability. In contrast, the B650I Lightning WiFi employs a Mini-ITX form factor, measuring 170mm x 170mm, which is ideal for compact builds and space-constrained environments. This difference in design means that while the B450M can accommodate more expansion slots and features, the B650I is engineered for users looking to save space without compromising on performance.

Supported Processors

The ASRock B450M/AC R2.0 supports AMD AM4 Socket Ryzen processors, including the 2000, 3000, 4000 G-Series, and 5000 series. This allows users to build systems with a range of AMD processors, but it is limited to older generations. On the other hand, the B650I Lightning WiFi supports the latest AMD Ryzen 9000, 8000, and 7000 series processors, making it a more future-proof choice for those looking to leverage the latest advancements in CPU technology.

Memory Support

When it comes to memory support, the ASRock B450M/AC R2.0 supports DDR4 memory with a maximum speed of 3200 MHz. In contrast, the B650I Lightning WiFi takes it a step further by supporting DDR5 memory, optimized for overclocked speeds up to 7200+ MHz. This difference in memory technology not only allows the B650I to handle higher speeds and bandwidth but also makes it more suitable for high-performance applications and gaming.

Connectivity Options

Connectivity is another area where the two motherboards differ significantly. The ASRock B450M/AC R2.0 features basic connectivity options, including HDMI output and a limited number of PCIe slots. However, the B650I Lightning WiFi boasts an advanced connectivity suite that includes Phantom Gaming 2.5G LAN, Intel WiFi 6E, and multiple USB 3.2 Gen2 ports. This extensive range of options makes the B650I a superior choice for users who prioritize fast networking and extensive peripheral connections.

Power Delivery and Efficiency

The ASRock B450M/AC R2.0 features a standard power delivery system, suitable for basic builds. In contrast, the B650I Lightning WiFi incorporates an advanced 8+2+1 phase power design with premium Dr.MOS components, ensuring exceptional stability and efficiency. This robust power delivery system is particularly beneficial for overclocking and maintaining system performance under heavy loads.

Audio and User Experience

The audio capabilities of the two motherboards also differ. The ASRock B450M/AC R2.0 provides basic audio output, suitable for everyday use. However, the B650I Lightning WiFi enhances the audio experience with a Realtek ALC897 7.1 CH HD Audio Codec, complemented by Nahimic Audio technology. This improvement allows for immersive and crystal-clear sound, making it better suited for gaming and media consumption.

Which should you buy?

Ultimately, the decision between the ASRock B450M/AC R2.0 and the ASRock B650I Lightning WiFi depends on your specific needs and budget. If you're looking for a cost-effective solution for older AMD processors and don't require the latest features, the B450M/AC R2.0 at $79.00 is an excellent choice. However, if you are interested in building a compact, future-proof system with the latest technology and superior performance, the B650I Lightning WiFi at $169.99 offers advanced features that justify the price. Consider what aspects are most critical for your PC build to make the best choice.
