MSI MAG B850 TOMAHAWK MAX WIFI Motherboard vs MSI X870E Gaming Plus WiFi ATX Motherboard - Supports AMD Ryzen 9000/8000/7000 P

Chipset and Core Architecture

Both motherboards support the latest AMD Ryzen 9000, 8000, and 7000 processors on the AM5 socket, but they differ fundamentally in their chipset choice. The MSI MAG B850 TOMAHAWK MAX WIFI uses the B850 chipset, positioning itself as the more accessible option for mainstream users. The MSI X870E Gaming Plus WiFi, by contrast, uses the premium X870E chipset, designed for enthusiasts seeking maximum performance and features. Both employ a 14 Duet Rail Power System with Core Boost architecture, though the B850 model features an 80A SPS VRM whilst the X870E model uses a 60A SPS VRM. The chipset choice impacts feature set, cooling capabilities, and overall system stability when pushing high-end components.

Power Delivery and Thermal Management

The MSI MAG B850 TOMAHAWK MAX WIFI delivers superior power delivery with its 80A SPS VRM system, making it better suited for power-hungry CPUs and overclocking scenarios. The MSI X870E Gaming Plus WiFi, with its 60A configuration, still provides ample power for demanding workloads but targets a slightly less extreme use case. Both boards feature the FROZR GUARD cooling technology, incorporating 7W/mK MOSFET thermal pads, extra choke thermal pads, and extended heatsinks. Both include chipset heatsinks and EZ M.2 Shield Frozr II protection to prevent M.2 drive thermal throttling. The combo-fan header on both boards supports pump and system cooling headers with 3A capacity, ensuring comprehensive thermal management for high-performance builds.

Memory and Overclocking Support

Memory handling differs slightly between these two platforms. The MSI MAG B850 TOMAHAWK MAX WIFI supports DDR5 memory overclocking up to 8400+ MT/s, whilst the MSI X870E Gaming Plus WiFi reaches 8200+ MT/s with overclocking. Both boards feature 4 x DDR5 DIMM SMT slots enabling 1DPC 1R configurations for extreme memory speeds, making them equally capable for memory-intensive workloads like content creation and simulation. The higher overclocking ceiling on the B850 model provides a marginal advantage for performance enthusiasts pursuing record-breaking memory clocks. For most users running standard or moderately overclocked memory profiles, both boards deliver comparable real-world performance and stability.

Storage Connectivity

Storage options represent a notable difference between these boards. The MSI MAG B850 TOMAHAWK MAX WIFI provides four M.2 connectors: two Gen5 x4 slots (128Gbps), one Gen4 x4 slot (64Gbps), and one Gen4 x2 slot (32Gbps), offering maximum flexibility for NVMe expansion. The MSI X870E Gaming Plus WiFi includes three M.2 connectors with one Gen5 x4 slot, two Gen4 x4 slots, but omits the Gen4 x2 option. The B850 model's additional M.2 slot and inclusion of the Gen4 x2 connector make it superior for users building high-storage systems or requiring backup capacity. However, for most users focused on a single or dual-NVMe setup, the X870E model's configuration remains perfectly adequate and matches real-world requirements.

PCIe and Graphics Card Support

Both motherboards feature a primary PCIe 5.0 x16 slot (128GB/s) with Steel Armor protection for graphics cards, supporting the latest NVIDIA and AMD GPUs. The MSI MAG B850 TOMAHAWK MAX WIFI features Steel Armor II, representing a marginally enhanced cooling variant. The key difference lies in secondary PCIe lanes: the B850 model includes only the primary x16 slot specification, whilst the X870E Gaming Plus WiFi offers an additional PCIe 4.0 x4 slot, providing more expansion flexibility for additional storage drives or networking cards. For single-GPU gaming and content creation builds, both boards excel equally. The X870E's secondary slot benefits users requiring multiple expansion cards or dual-GPU configurations, though such setups are increasingly rare in modern computing.

Network and Audio Connectivity

Both boards share identical modern networking specifications, featuring Wi-Fi 7 with Bluetooth 5.4 and 5Gbps LAN connectivity. However, the rear port configurations differ noticeably. The MSI MAG B850 TOMAHAWK MAX WIFI includes USB 20G Type-C and 7.1 USB High Performance Audio with Audio Boost 5 supporting S/PDIF output, catering to audiophiles requiring legacy digital audio connections. The MSI X870E Gaming Plus WiFi substitutes the USB 20G for USB4 Type-C 40Gbps with display output and offers 7.1 HD Audio with Audio Boost, prioritising next-generation connectivity over legacy audio features. The X870E's USB4 port provides superior bandwidth for external storage and monitors, whilst the B850's S/PDIF output appeals to dedicated audio setups.

Price and Market Value

Pricing favours the MSI X870E Gaming Plus WiFi, currently available at £199.99 compared to the MSI MAG B850 TOMAHAWK MAX WIFI at £208.99. The X870E model has maintained stable pricing around £199.99 for the past 30 days, suggesting consistent value, whilst the B850 shows slightly higher 30-day and 90-day averages (£215.29 and £222.71 respectively), indicating recent price stabilisation. For a budget-conscious builder, the X870E represents approximately £9 savings upfront. Both models demonstrate strong market positioning with the B850 ranking 7th and the X870E ranking 10th in their category's bestseller charts. When considering the performance premium offered by the B850's superior power delivery and M.2 connectivity, the price difference becomes reasonable for enthusiast-grade builds.

Which should you buy?

Choose the MSI MAG B850 TOMAHAWK MAX WIFI if you prioritise maximum power delivery, extensive storage expansion with four M.2 slots, and higher memory overclocking potential up to 8400+ MT/s. This board excels for power users, overclockers, and content creators requiring multiple NVMe drives and maximum stability under extreme loads. Conversely, select the MSI X870E Gaming Plus WiFi if you prefer a premium chipset platform, modern USB4 connectivity, and strong value at a lower price point. The X870E's enhanced connectivity and stable pricing make it ideal for gamers and creators seeking a balanced feature set without paying extra for capabilities they won't utilise. Both deliver exceptional AM5 platform support, but your choice ultimately depends on whether you need the B850's specialist features or prefer the X870E's streamlined modern approach.
