Dimension comparison
Overview of the MSI MPG B550 GAMING PLUS and MSI B850 GAMING PLUS WIFI6E
The MSI MPG B550 GAMING PLUS is priced at £99.98, while the MSI B850 GAMING PLUS WIFI6E retails for £119.99. This price difference of £20 reflects the varying features and capabilities of the two motherboards. Both motherboards cater to gamers and PC builders, but they do so with different specifications and support for different generations of AMD processors.
Processor Support
The MSI MPG B550 GAMING PLUS supports AMD Ryzen 3rd generation processors, while the MSI B850 GAMING PLUS WIFI6E is built for the latest Ryzen 7000, 8000, and 9000 series processors. This means that if you are looking to build a high-performance system with the most recent technology, the B850 is the better choice. The B850’s support for the newer processor generations makes it more future-proof, allowing for potentially higher performance in demanding applications and games.
Memory Compatibility
In terms of memory, the MSI MPG B550 GAMING PLUS can accommodate up to 128GB of DDR4 RAM, providing substantial capacity for multitasking and gaming. In contrast, the MSI B850 GAMING PLUS WIFI6E pushes the envelope further with support for DDR5 memory, allowing for speeds of over 8200 MT/s when overclocked. This significant leap in memory technology means that the B850 is better suited for users who require the fastest memory speeds for intensive workloads, making it a more attractive option for high-performance builds.
Connectivity Features
When it comes to connectivity, the MSI B850 GAMING PLUS WIFI6E offers modern options like a premium Wi-Fi 6E module and Bluetooth 5.3, ensuring fast and reliable wireless connections. It also features a 2.5Gbps LAN for high-speed wired internet access. On the other hand, while the MPG B550 GAMING PLUS includes USB 3.2 Gen 2, it lacks the advanced wireless features of the B850. For users prioritising cutting-edge connectivity, the B850 clearly outshines the B550.
Cooling Solutions
The MSI B850 GAMING PLUS WIFI6E features advanced cooling solutions, including MOSFET thermal pads and an extended heatsink, contributing to better thermal management during intensive tasks. The B550 also boasts an enhanced thermal solution with a 7 WmK level thermal pad and extended heatsink but lacks some of the additional cooling features present in the B850. This makes the B850 a better choice for users who intend to push their systems to the limit, as it provides more robust cooling capabilities.
Expansion Slots
In terms of expansion, the MSI B850 GAMING PLUS WIFI6E offers two M.2 connectors, including one that supports Gen5 speeds, allowing for extremely fast storage solutions. The MPG B550 GAMING PLUS, while it includes dual M.2 slots as well, doesn’t support the latest Gen5 technology. This difference is crucial for users looking to achieve the highest storage speeds for gaming and data-intensive applications. Thus, the B850 stands out with its superior expansion capabilities.
Audio Quality
Audio performance is another area where the MSI B550 GAMING PLUS shines with its AUDIO BOOST feature, providing studio-grade sound quality for an immersive gaming experience. The B850 also includes Audio Boost technology, ensuring high-quality audio output. While both motherboards aim to provide excellent audio experiences, the B550's focus on this feature may appeal to audiophiles and gamers alike who value sound quality in their gaming setups.
Aesthetics and Customisation
Both motherboards come with MSI’s Mystic Light technology, enabling RGB lighting customisation. However, the B550 specifically mentions support for 16.8 million colours and various effects controlled in one click, giving it a slight edge in personalisation options. For users who enjoy customising their builds for aesthetic appeal, the MPG B550 GAMING PLUS might be the more attractive option, although both motherboards offer good options for lighting effects.
Which should you buy?
Deciding between the MSI MPG B550 GAMING PLUS and MSI B850 GAMING PLUS WIFI6E ultimately depends on your specific needs. If you are looking for a budget-friendly motherboard that supports Ryzen 3rd generation processors and offers solid gaming features, the B550 is a great choice at £99.98. However, if you want to invest in a more future-proof system that supports the latest Ryzen processors, DDR5 memory, and advanced connectivity options, the B850 at £119.99 is the superior option. Overall, for high-performance builds and modern features, the MSI B850 GAMING PLUS WIFI6E is the clear winner.
