Overview of the Gigabyte A520I AC and SHANGZHAOYUAN B85M PRO

The Gigabyte A520I AC is priced at $99.99, while the SHANGZHAOYUAN B85M PRO costs $79.99, making it about 17% cheaper than its competitor. Both motherboards cater to different processor families and form factors, with the A520I AC supporting AMD Ryzen processors and the B85M PRO designed for Intel's 4th generation Core processors. This article will delve into their respective features, performance capabilities, and overall value to help you decide which motherboard fits your needs better.

Performance Comparison

In terms of performance, the Gigabyte A520I AC is optimized for 3rd Gen AMD Ryzen processors with its AM4 socket, offering a Direct 6 Phases Digital PWM with 55A DrMOS. This configuration promises efficient power delivery, which can enhance overall system performance. The B85M PRO, on the other hand, supports Intel’s 4th gen processors such as the i7 and i5 series, utilizing a 4-phase power supply design. While both motherboards have strong power management features, the A520I AC's VRM design is geared toward high-performance gaming scenarios, making it a more suitable choice for users aiming for robust gaming capabilities.

Memory Support

The memory support in both motherboards is significant, but they differ in type and capacity. The Gigabyte A520I AC features dual-channel DDR4 memory support with a maximum of 32GB across 2 DIMMs, which is ideal for modern applications and gaming. In contrast, the SHANGZHAOYUAN B85M PRO supports dual-channel DDR3 memory with a maximum capacity of 32GB as well, but at lower frequencies of 1333/1600/1866 MHz. DDR4 memory in the A520I AC allows for faster speeds and improved performance in memory-intensive tasks, providing an edge over the B85M PRO’s older DDR3 standard.

Connectivity Options

Connectivity is another crucial factor where the Gigabyte A520I AC excels. It offers one PCIe 3.0 x16 slot and a single NVMe PCIe 3.0 x4 M.2 slot, making it well-equipped for high-speed storage solutions. Additionally, it includes multiple display interfaces, such as rear DisplayPort and dual HDMI outputs. The B85M PRO also features a PCIe 3.0 x16 slot and an M.2 slot but lacks the variety of display outputs available on the A520I AC. For users looking to build a multi-display setup or leverage high-speed storage, the A520I AC provides superior flexibility.

Integrated Features

The integrated features of both motherboards also cater to different user needs. The Gigabyte A520I AC includes ALC887 audio codec for decent sound quality, Intel Dual Band AC WiFi, and Bluetooth capabilities, enhancing its appeal for multimedia use. It also boasts RGB Fusion 2.0 support, allowing for customizable lighting effects in compatible setups. In contrast, the SHANGZHAOYUAN B85M PRO focuses on basic functionalities without advanced audio or wireless integrations, making it a more straightforward option for users who do not require extensive multimedia features.

Form Factor and Design

Form factor plays a significant role in motherboard selection, especially for compact builds. The Gigabyte A520I AC is a Mini-ITX motherboard, ideal for small form factor builds, while the B85M PRO adopts a Micro-ATX design, providing more expansion options at the cost of size. The A520I AC’s compact design is great for users who want to build a space-efficient gaming rig or home theater PC. However, those needing more expansion slots for additional components may find the B85M PRO’s larger size advantageous.

Price Consideration

At a price of $99.99, the Gigabyte A520I AC is positioned at a premium compared to the $79.99 price of the SHANGZHAOYUAN B85M PRO. This approximately 17% price difference reflects the A520I AC's additional features and support for newer technology. For users on a budget, the B85M PRO offers solid performance for older Intel processors, but it lacks many modern features found in the A520I AC. Therefore, the decision may ultimately hinge on whether the added functionalities of the A520I AC justify the higher price for potential buyers.

User Experience and Reliability

User experience can be a crucial factor when considering a motherboard. The Gigabyte A520I AC is well-regarded for its stability and performance, particularly among gamers and content creators. The optimized VRM heatsink and robust power delivery system contribute to a reliable experience. Conversely, while the SHANGZHAOYUAN B85M PRO is a functional motherboard, it may not provide the same level of reliability under heavy loads due to its simpler design and older components. Users seeking a dependable motherboard for demanding tasks might lean toward the A520I AC for its enhanced stability.

Which should you buy?

Choosing between the Gigabyte A520I AC and SHANGZHAOYUAN B85M PRO ultimately depends on your specific needs and budget. If you prioritize modern features, performance, and a compact design, the A520I AC is a strong contender, albeit at a higher price of $99.99. Conversely, if you are looking for a budget-friendly option that supports older Intel processors and don’t require advanced features, the B85M PRO at $79.99 is a solid choice. Each motherboard caters to different user bases, so consider your requirements carefully before making a purchase.
