It’s been two years since AMD launched its AM5 motherboard platform and the 600-series motherboards. This period has welcomed a range of CPUs from the Ryzen 7000 to the Ryzen 9000 families. While the 600-series offers impressive features and compatibility with the latest Zen 5 CPUs, enthusiasts are always hungry for more innovation. Enter the 800-series chipset, AMD’s latest advancement to enhance user experience with cutting-edge technology.
Last year, AMD introduced the 800-series motherboards, starting with the X870E and X870 variants alongside the Ryzen 9000 processors. Recently, these were followed by the B850 and B840 series, offering exciting new designs and features perfect for both new AMD builders and those looking to upgrade from older AM4 models.
Today, we’re diving into MSI’s B850M Mortar WIFI motherboard. Priced attractively around $150, this motherboard provides a fantastic range of capabilities without breaking the bank.
The Evolution of the AMD AM5 Platform
The AMD AM4 platform, launched in 2017, has proven remarkably resilient, continuing to thrive in 2024. With recent chip launches, it seems AMD plans to keep it around for a while longer. However, the spotlight is now on the second-generation AM5 platform, featuring the 800-series family. While initial releases targeted high-end enthusiasts, the new B850E and B850 options bring these innovations to a more budget-friendly segment.
Exploring the B850 Chipset
The AMD B850 chipset marries both Gen5 and Gen4 capabilities. Gen5 is typically harnessed for NVMe storage, while Gen4 supports graphics. Manufacturers can also allocate Gen5 lanes for discrete graphics when needed. The AM5 boards also support USB 3.2 (20 Gbps), though high-end options feature USB4. The configuration supports x16 Gen4 or x8 Gen5/Gen4 graphics setups. Importantly, B850 motherboards accommodate both memory and CPU overclocking, aiming squarely at Intel’s B760 lineup, largely in the $100-$200 range.
Advanced Features and Specifications
AMD offers a dazzling array of features with the 800-series. The B850 motherboards include Promontory 21 die, excluding native USB4 support but retaining Gen5 GPU support (with optional Gen5 M.2). The B840 serves as an entry-level option with Promontory 19, offering Gen4 GPU/SSD support. Meanwhile, AMD maintains the A620/A620A series for budget-conscious consumers, promising competitive pricing against Intel.
The LGA 1718 Socket and Future Prospects
The transition from the AM4 platform to the AM5 socket marks a shift from PGA to LGA design, increasing pin connections and supporting more advanced features. AMD commits to extending AM5’s relevance well into 2027 and beyond, ensuring long-term support and innovation.
Cooler Compatibility
The AMD Ryzen 7000/8000/9000 CPUs maintain a 45x45mm form with a robust integrated heat spreader. This design means existing coolers can seamlessly fit the latest Ryzen processors, ensuring a smooth upgrade path.
These recent advancements continue to make AMD a formidable force in the world of CPUs and motherboards, catering to both budget and high-performance seekers alike. With the 800-series, AMD sets a new standard for power, compatibility, and innovation.
