Price Comparison
When it comes to pricing, the MACHINIST X99 is significantly more affordable than the ASRock B650I Lightning WiFi. The ASRock B650I Lightning WiFi is priced at $169.99, while the MACHINIST X99 costs only $76.99. This means the MACHINIST X99 is about 55% cheaper than the ASRock option. For budget-conscious consumers or those looking to build a system without breaking the bank, the MACHINIST X99 presents a compelling choice.
Form Factor
The ASRock B650I Lightning WiFi is designed in a compact Mini-ITX form factor, measuring 170mm x 170mm, which is ideal for small form factor builds. In contrast, the MACHINIST X99 is an M-ATX motherboard, providing a larger footprint that allows for more expandability and additional components. If space is a primary concern, the ASRock is the better option, while the MACHINIST may appeal to users looking for more slots and features at the cost of additional size.
Processor Compatibility
Processor compatibility is a key differentiator between these two motherboards. The ASRock B650I Lightning WiFi supports AMD Ryzen 9000, 8000, and 7000 series processors, ensuring compatibility with the latest AMD technology. Meanwhile, the MACHINIST X99 is designed for Intel's LGA 2011-v3 socket, supporting the Intel Xeon E5 V3/V4 series and Core i7 5th and 6th generation processors. This means that the ASRock offers more future-proofing with its support for newer AMD CPUs, while the MACHINIST caters to users invested in Intel's older architecture.
Memory Support
In terms of memory support, the ASRock B650I Lightning WiFi has an advantage with its dual DDR5 DIMM slots, optimized for overclocked speeds of up to 7200+ (OC). This modern memory technology can significantly enhance performance in gaming and productivity tasks. On the other hand, the MACHINIST X99 supports 4-channel DDR4 memory, allowing for a maximum capacity of 128GB (4 x 32GB). While it supports ECC, RECC, and non-ECC memory, it lacks the speed and efficiency of DDR5. Therefore, if high-speed memory is a priority, the ASRock is the superior choice.
Connectivity Options
Connectivity features are essential for modern computing needs. The ASRock B650I Lightning WiFi boasts an impressive suite of connectivity options, including Phantom Gaming 2.5G LAN, Intel WiFi 6E, and multiple USB 3.2 Gen2 ports, including front and rear Type-C. In comparison, the MACHINIST X99 offers Gigabit LAN and various USB 3.0 options but lacks WiFi capabilities unless an additional M.2 WiFi module is installed. For users prioritizing advanced connectivity and faster network speeds, the ASRock is undoubtedly the better option.
Storage Solutions
For storage solutions, the ASRock B650I Lightning WiFi features a blazing M.2 PCIe 5.0 x4 slot that allows for cutting-edge NVMe SSD speeds, along with dual M.2 slots and two SATA3 ports for versatile storage configurations. Conversely, the MACHINIST X99 includes three NVME M.2 slots (PCIe 3.0 x4) and SATA 6Gbps support. While both motherboards offer ample storage options, the ASRock leads in speed with its PCIe 5.0 compatibility, making it more suitable for high-performance storage setups.
Power Delivery System
The power delivery systems of both motherboards reflect their design philosophies. The ASRock B650I Lightning WiFi features an 8+2+1 phase power design with premium Dr.MOS components, ensuring exceptional stability and efficiency, particularly for overclocking. In contrast, the MACHINIST X99 utilizes a 6-phase power supply, which, while adequate, may not offer the same level of performance under heavy loads. For users looking to push their CPUs to the limit, the ASRock’s robust power delivery system provides a clear advantage.
Which should you buy?
Choosing between the ASRock B650I Lightning WiFi and the MACHINIST X99 largely depends on your specific needs and budget. If you are looking for cutting-edge technology, advanced features, and the best performance, the ASRock B650I Lightning WiFi is worth the investment at $169.99. However, if you are on a tighter budget and still want a reliable motherboard that supports older Intel processors, the MACHINIST X99 at $76.99 offers excellent value. Ultimately, your choice should align with your processor preference, performance goals, and budget constraints.
