GIGABYTE Z790 UD AC LGA 1700 ATX Motherboard,MSI B650 Gaming Plus WiFi Motherboard AMD B650

Price Comparison

The GIGABYTE Z790 UD AC is priced at $149.99, while the MSI B650 Gaming Plus WiFi has a higher price of $171.54. This makes the GIGABYTE model about 17% cheaper than the MSI motherboard. Price can often be a deciding factor for consumers, especially for those looking to build a gaming rig on a budget. The lower price of the GIGABYTE Z790 UD AC may appeal to gamers who want to optimize their spending without compromising on performance. However, the additional features of the MSI motherboard may justify its higher cost for some users.

Compatibility and Processor Support

The GIGABYTE Z790 UD AC supports Intel Core processors from the 12th to 14th generation, providing a broad range of compatibility for users looking to upgrade or build a new system. In contrast, the MSI B650 Gaming Plus WiFi is designed for AMD’s B650 chipset, supporting Ryzen processors from the 7000 to the upcoming 9000 series. This distinction is crucial for consumers who have a preference for either Intel or AMD, as it directly influences the choice of CPU and overall system compatibility. Therefore, the decision between these two motherboards may hinge significantly on the user's preferred processor brand.

Memory and Performance Features

In terms of memory, the GIGABYTE Z790 UD AC supports dual-channel DDR5 memory with four DIMM slots, enabling efficient multitasking and high-speed performance. On the other hand, the MSI B650 Gaming Plus WiFi also supports DDR5 with four DIMM slots but offers enhanced overclocking capabilities, with configurations reaching up to 6400+ MHz. This means that while both motherboards are capable of high-performance memory support, the MSI motherboard provides additional features for users interested in pushing their memory to its limits. Such performance enhancements can be particularly attractive to gamers and content creators looking for top-tier performance.

Cooling Solutions

When it comes to cooling solutions, the MSI B650 Gaming Plus WiFi has a more robust thermal management system, featuring an extended heatsink, dedicated pump-fan cooling header, and M.2 Shield Frozr to prevent thermal throttling. The GIGABYTE Z790 UD AC also boasts a comprehensive thermal design with fully covered MOSFET heatsinks and an M.2 thermal guard, but it may not rival the depth of MSI’s cooling features. Effective cooling is essential for maintaining optimal performance during intense gaming sessions, making this an important consideration for users who plan to overclock their systems or run demanding applications.

Connectivity Options

Connectivity is another area where both motherboards shine, but they cater to different needs. The GIGABYTE Z790 UD AC includes PCIe 5.0, multiple NVMe PCIe 4.0 M.2 slots, and USB-C 3.2, ensuring high-speed data transfer and future-proofing for newer devices. The MSI B650 Gaming Plus WiFi, however, stands out with its Wi-Fi 6E capabilities, Bluetooth 5.3, and dual M.2 Gen4 slots. This means that while the GIGABYTE motherboard offers advanced PCIe support, the MSI model provides superior wireless connectivity options, making it more appealing for users who prioritize a wireless setup or require faster networking speeds.

Build Quality and Durability

Both motherboards are built with quality in mind, featuring durable designs that include a 6-layer PCB. However, the MSI B650 Gaming Plus WiFi enhances its durability with 2 oz. of thickened copper and Steel Armor for its primary PCIe slot. This can be particularly beneficial for gamers using high-end graphics cards, as it can help prevent damage and ensure stability during operation. The GIGABYTE Z790 UD AC also emphasizes reliability with its ultra-durable armor and thermal designs, but the MSI's additional features may offer an edge in terms of long-term durability and performance under heavy loads.

User Experience and Ease of Use

User experience can greatly influence the decision between these two motherboards. The GIGABYTE Z790 UD AC includes features like EZ-Latch and Q-Flash, which simplify installation and BIOS updates, making it a user-friendly option for both beginners and seasoned builders. The MSI B650 Gaming Plus WiFi, while not lacking in ease of use, focuses more on performance-centric features, which might be more appealing to those with experience in system building. Ultimately, if a straightforward build process is a priority, the GIGABYTE model may be the better choice.

Which should you buy?

Choosing between the GIGABYTE Z790 UD AC and the MSI B650 Gaming Plus WiFi ultimately depends on your specific needs and preferences. If you are looking for a cost-effective solution with solid performance and ease of use, the GIGABYTE Z790 UD AC at $149.99 is a compelling option. However, if you prioritize advanced cooling features, superior wireless connectivity, and support for the latest Ryzen processors, the MSI B650 Gaming Plus WiFi may justify its higher price of $171.54. Each motherboard has its strengths, so consider your build requirements and personal preferences carefully before making a decision.
