Winner

GIGABYTE B850M EAGLE WIFI6E Motherboard - AMD Ryzen 9000 Series CPUs.

The Gigabyte B850M Eagle WiFi6E is a sensible comparison baseline given its memory speed and micro-ATX form factor, not a declared performance winner.

1. MSI PRO B850-S WIFI6E motherboard AMD B850 Socket AM5 ATX

Check price at PCHub

Price shown £103.47

The cheapest board here, offering Wi-Fi 6E and PCIe 5.0 storage on a full ATX layout.

The MSI PRO B850-S WIFI6E pairs the B850 chipset with Wi-Fi 6E, 2.5G LAN and a PCIe 5.0 M.2 slot protected by M.2 Shield Frozr, with Ryzen 9000 support subject to BIOS.

Its networking trails the Wi-Fi 7 and 5G LAN fitted to the pricier MSI Gaming Plus and Tomahawk boards, though it remains the most affordable ATX option in this group.

View exact-model Geekbench 6 result. The Geekbench Browser identifies the exact motherboard and marks this result valid. These are scores for one complete system using the named processor, memory and operating system, so they should not be treated as a motherboard performance rating or compared directly with results using another CPU.

At £103.47 it undercuts the Gigabyte B650 Eagle AX by £7.85 and the MSI Tomahawk by £93.95.

2. GIGABYTE B650 EAGLE AX Motherboard

Check price at PCHub

Price shown £111.32

The sole B650 chipset board in this lineup, with limited published feature detail beyond the model name.

The Gigabyte B650 Eagle AX uses the AM5 socket with the B650 chipset, standing apart from the four B850 boards in this comparison, though detailed specification data beyond the model name is not supplied.

Buyers should confirm networking, M.2 configuration and memory support directly, since this listing carries less confirmed connectivity information than the other four boards here.

View TechSpot B650 motherboard thermal results. The result is from TechSpot's B650 board chart and describes this board's VRM thermal behaviour under a high-load CPU test. It is a board-specific thermal result, not a CPU performance score. Compare temperatures only with boards tested by the same method.

At £111.32 it costs £7.85 more than the MSI PRO B850-S but £86.10 less than the MSI Tomahawk.

3. GIGABYTE B850M EAGLE WIFI6E Motherboard - AMD Ryzen 9000 Series CPUs.

Check price at PCHub

Price shown £117.47

The only micro-ATX board here, pairing Wi-Fi 6E with the highest stated overclocked memory speed in this group.

The Gigabyte B850M Eagle WiFi6E fits a micro-ATX form factor with Wi-Fi 6E, 2.5 GbE LAN, one PCIe 5.0 and one PCIe 4.0 M.2 slot, and DDR5 support up to 8200 MHz DDR5 overclocked.

That memory figure is the highest stated among these five boards, though its micro-ATX size and Wi-Fi 6E networking set it apart from the four full ATX boards with varying Wi-Fi standards.

Peak PCB backside temperature: 91°C
Cinebench 2024 score after stress test: 2,284 points

View TechSpot B850 motherboard test table. The Cinebench result followed the one-hour thermal stress test, and TechSpot reports that this board was power-limited to 170 W. These figures describe the tested board and full test system, not an isolated motherboard score. The 91°C figure is the peak PCB backside reading, so it is not directly interchangeable with MOSFET sensor or infrared readings from other reviews.

At £117.47 it sits close to the Gigabyte B650 Eagle AX, just £6.15 more, and well below the MSI Tomahawk at £197.42.

4. MSI B850 GAMING PLUS WIFI motherboard AMD B850 Socket AM5 ATX

Check price at PCHub

Price shown £149.21

An ATX board matching the Tomahawk networking spec while costing considerably less.

The MSI B850 Gaming Plus WiFi offers Wi-Fi 7, 5G LAN and PCIe 5.0 storage on a full ATX board, matching the networking specification of the pricier MSI Tomahawk.

It lacks the USB 20 Gbps port listed on the Tomahawk, the main stated difference between the two MSI boards despite their shared Wi-Fi 7 and 5G LAN connectivity.

5. MSI MAG B850 TOMAHAWK WIFI motherboard AMD B850 Socket AM5 ATX

Check price at PCHub

Price shown £197.42

The priciest board here, distinguished by its USB 20 Gbps port alongside Wi-Fi 7 and 5G LAN.

The MSI MAG B850 Tomahawk WiFi combines Wi-Fi 7, 5G LAN, PCIe 5.0 storage and a USB 20 Gbps port, the only board in this comparison to list that USB specification.

Its price sits well above the similarly networked MSI Gaming Plus, with the USB 20 Gbps port as the clearest stated difference between the two MSI ATX boards.

View The FPS Review test results and methods. The review identifies a Ryzen 9 7900X as its 2026 AMD test CPU. Its HWiNFO MOSFET temperature is reported with an inconsistent Fahrenheit unit, so that sensor value is omitted here. The infrared temperature uses a different measurement method from PCB thermocouple results and should not be ranked directly against them.

At £197.42 it is the most expensive board in this group, £93.95 more than the entry-level MSI PRO B850-S.
