Dimension comparison
Overview
In this comparison, we pit the ASRock AMD B850i Lightning against the NZXT N9 X870E, two robust motherboards designed for AMD's Ryzen 9000, 8000, and 7000 series processors. The ASRock board is priced at $179.99, while the NZXT variant comes in at $499.99, making it approximately 178% more expensive. Each motherboard targets different segments of the market, with unique features catering to distinct user needs.
Design and Form Factor
The ASRock AMD B850i Lightning features a compact Mini-ITX design, measuring 170x170mm. This makes it ideal for users looking to build small form factor (SFF) PCs. In contrast, the NZXT N9 X870E adopts a standard ATX layout, which provides more space for additional components. The full-metal cover on the NZXT adds a touch of elegance while concealing the PCB, enhancing the overall aesthetic. Therefore, if space-saving design is a priority, the ASRock motherboard is the better option, while the NZXT offers more expandability.
Power Delivery
When it comes to power delivery, the NZXT N9 X870E excels with a 20+2+1 power phase design, utilizing 110A Smart Power Stages to ensure stable performance during overclocking. The ASRock AMD B850i Lightning, on the other hand, features a 10+1+1 phase power design, which while adequate for most users, may not offer the same level of stability under extreme conditions. For serious gamers and overclockers, the NZXT’s superior power delivery system can provide a significant advantage.
Memory Support
The memory capabilities of these two motherboards highlight a major difference. The ASRock model supports two DDR5 DIMM slots with speeds up to 8200 MHz (overclocked), while the NZXT supports four DIMM slots with DDR5 memory speeds also exceeding 8000 MT/s. This means that the NZXT can accommodate more memory, which is beneficial for users looking for high-performance multitasking or demanding applications. If maximum RAM capacity is essential for your setup, the NZXT is the clear choice.
Storage Options
Storage possibilities vary greatly between the two models. The ASRock AMD B850i Lightning offers dual M.2 slots for high-speed storage, including one PCIe 5.0 and one PCIe 4.0. Conversely, the NZXT N9 X870E provides four M.2 slots—one PCIe 5.0 and three PCIe 4.0—along with quick-release latches for easier installation and upgrades. The additional M.2 slots on the NZXT board not only allow for more storage options but also facilitate faster data access, making it suitable for users with extensive storage needs.
Networking Capabilities
Networking features are another critical aspect where these motherboards differ. The ASRock model includes Killer 2.5G LAN and WiFi 6E, offering great connectivity options for gaming and streaming. In comparison, the NZXT N9 X870E comes equipped with WiFi 7 and 5GbE, providing significantly faster networking speeds and lower latency. If online gaming or high-speed data transfer is a priority, the NZXT’s advanced networking capabilities offer a notable advantage.
Aesthetics and Build Quality
Aesthetics are subjective, but both motherboards cater to different tastes. The ASRock AMD B850i Lightning maintains a straightforward and functional look, suitable for compact builds. The NZXT N9 X870E, however, features customizable RGB lighting and a premium full-metal cover, providing a more modern and stylish appearance. For users who value aesthetics alongside performance, the NZXT motherboard is likely to appeal more.
Pricing and Value
Price-wise, the ASRock AMD B850i Lightning is positioned at $179.99, making it a budget-friendly option, while the NZXT N9 X870E is priced at $499.99. This price difference of $320 represents about 178% more for the NZXT. While the ASRock motherboard offers great value for entry-level and mid-range builds, the NZXT caters to enthusiasts willing to invest more for enhanced features and performance. Ultimately, the choice will depend on your budget and specific needs.
Which should you buy?
In conclusion, the choice between the ASRock AMD B850i Lightning and the NZXT N9 X870E boils down to your specific requirements and budget. If you are looking for a compact, cost-effective solution for basic gaming or productivity, the ASRock model is an excellent choice at $179.99. Conversely, if you are an enthusiast aiming for high performance and are willing to invest in advanced features, the NZXT N9 X870E, despite its higher price of $499.99, offers superior power delivery, memory support, and networking capabilities. Assess your needs carefully to make the best decision.
