Overview of GIGABYTE Z790 UD AC and SHANGZHAOYUAN B85M PRO
The GIGABYTE Z790 UD AC is priced at $149.99, while the SHANGZHAOYUAN B85M PRO is significantly cheaper at $79.99, making it about 47% less expensive. This price difference reflects the advanced features and technology present in the GIGABYTE model, which supports the latest Intel processors and offers enhanced performance for gaming and productivity tasks. In contrast, the SHANGZHAOYUAN motherboard is aimed at users looking for basic functionality for older Intel 4th generation CPUs.
Processor Compatibility
The GIGABYTE Z790 UD AC supports Intel’s latest 14th, 13th, and 12th Generation processors with an LGA 1700 socket. This compatibility allows users to leverage the latest advancements in processing power, providing better performance in gaming and multitasking scenarios. Conversely, the SHANGZHAOYUAN B85M PRO is limited to 4th Generation Intel processors, including the Core i7, i5, and i3 series. This restricts its use to older technology, which may not meet the demands of contemporary software and gaming.
Memory Support
The GIGABYTE Z790 UD AC offers dual-channel DDR5 memory support, accommodating up to four DIMMs. This allows for higher memory speeds and greater bandwidth, essential for high-performance applications. In contrast, the SHANGZHAOYUAN B85M PRO supports dual-channel DDR3 memory with a maximum capacity of 32GB. While DDR3 can still handle basic tasks, it lacks the speed and efficiency of DDR5, making the GIGABYTE board a better choice for future-proofing your build.
Power Design and Stability
The GIGABYTE Z790 UD AC boasts a sturdy 16+1+1 power phase design, which ensures stable and efficient power delivery, critical for high-end processors and overclocking. This sophisticated power design is complemented by features like fully covered MOSFET heatsinks and a 6-layer PCB for enhanced thermal performance. On the other hand, the SHANGZHAOYUAN B85M PRO utilizes a simpler 4-phase power supply. While adequate for its intended use, it may not provide the same level of stability under heavy loads or during extended use.
Connectivity Options
In terms of connectivity, the GIGABYTE Z790 UD AC is equipped with next-generation options, including PCIe 5.0, three NVMe PCIe 4.0 M.2 slots, and SuperSpeed USB 3.2 Gen 2x2 Type-C. This extensive connectivity supports the fastest data transfer speeds and multiple high-speed devices, perfect for modern gaming setups. In contrast, the SHANGZHAOYUAN B85M PRO features PCIe 3.0 and offers basic connectivity with one PCIe x16 slot, one PCIe x1 slot, and three SATA 3.0 ports. While it may suffice for basic usage, it lacks the advanced options needed for high-performance builds.
Thermal Management
The GIGABYTE Z790 UD AC is designed with comprehensive thermal management features, including M.2 thermal guards and ultra-durable armor. These features help maintain optimal operating temperatures, thereby enhancing performance and longevity. The SHANGZHAOYUAN B85M PRO, while it includes heat dissipation armor, does not offer the same level of thermal management, which may affect performance during intensive tasks or prolonged use.
User Experience and Design
Aesthetically, the GIGABYTE Z790 UD AC features RGB Fusion technology, allowing users to customize the lighting of their motherboard to match their gaming setup. Its advanced design caters to tech enthusiasts looking for a visually appealing and high-performing motherboard. The SHANGZHAOYUAN B85M PRO, on the other hand, has a more utilitarian design focused on functionality rather than aesthetics. While it may lack the flair of the GIGABYTE model, it can still serve as a reliable choice for basic computing needs.
Which should you buy?
In conclusion, if you're looking for a motherboard that supports the latest Intel processors, offers robust memory support, and features advanced connectivity options, the GIGABYTE Z790 UD AC is the clear winner at $149.99. However, if you're working with an older Intel 4th Generation CPU and need a more budget-friendly option, the SHANGZHAOYUAN B85M PRO at $79.99 may suffice. Ultimately, your choice should align with your specific needs and the performance you expect from your system.
