Price Comparison
The ASRock AMD B850i Lightning WiFi 6E is priced at $179.99, while the B450M-HDV R4.0 costs significantly less at $72.47. This makes the B450M-HDV R4.0 about 60% cheaper than its counterpart. When considering a budget-friendly option, the B450M-HDV R4.0 provides substantial savings, especially for users who may not require the advanced features of the B850i Lightning. However, those looking for cutting-edge technology might find the higher price of the B850i justified given its capabilities.
Performance Capabilities
In terms of performance, the ASRock AMD B850i Lightning WiFi 6E offers superior specifications, supporting AMD Ryzen 9000, 8000, and 7000 series processors with DDR5 memory speeds of up to 8200+ MHz. In contrast, the B450M-HDV R4.0 is compatible with older Ryzen 2000 to 5000 processors and supports DDR4 memory speeds of up to 3200 MHz. The B850i's advanced 10+1+1 phase power design ensures stable performance in compact builds, which is essential for high-performance gaming or intensive tasks. For users focused on performance, the B850i Lightning is the clear winner.
Form Factor and Design
The ASRock AMD B850i Lightning WiFi 6E features a Mini-ITX compact design, making it ideal for small form factor builds, measuring 170x170mm. This compactness comes with the advantage of fitting into smaller cases, which can be a significant benefit for users with limited space. Conversely, the B450M-HDV R4.0 utilizes a Micro ATX form factor. While the Micro ATX provides more expansion options, it may not fit in smaller cases as easily as the Mini-ITX design of the B850i. The choice between these two motherboards may depend on the user’s case size and overall build preferences.
Memory and Storage Options
The B850i Lightning supports dual-channel configurations with two DDR5 DIMM slots, allowing for a total of 128GB of memory. This is particularly beneficial for users who require extensive multitasking capabilities or run memory-intensive applications. Meanwhile, the B450M-HDV R4.0 supports up to 64GB of DDR4 RAM across its two DIMM slots. Regarding storage, the B850i features dual M.2 slots (one PCIe Gen5x4 and one Gen4x4) for high-speed storage solutions, whereas the B450M has one Ultra M.2 slot supporting PCIe Gen3x4. Users focused on maximizing their system’s memory and storage performance will find the B850i more accommodating.
Connectivity Features
The ASRock AMD B850i Lightning WiFi 6E excels in connectivity with Killer 2.5G LAN, WiFi 6E, and Bluetooth, ensuring high-speed wired and wireless connections. It also includes USB 3.2 Gen2 Type-C ports capable of speeds up to 40Gb/s, which is advantageous for modern peripherals. The B450M-HDV R4.0, while functional, offers standard connectivity options such as HDMI, DVI-D, and D-Sub outputs along with Realtek Gigabit LAN. Users who prioritize cutting-edge connectivity will appreciate the B850i’s enhanced capabilities, especially in a world increasingly dependent on high-speed internet and data transfer.
Audio and Video Outputs
In terms of audio, the B450M-HDV R4.0 features a 7.1 channel HD audio codec, which can deliver a solid audio experience for gaming and multimedia. It also supports HDMI and DVI-D for video output.
