Has integrated CPU

At their core, the Asus ROG Strix B850-A Gaming WiFi and the MSI MAG B850 Tomahawk Max WiFi share an identical platform foundation: both use the AM5 socket with a B850 chipset, follow the standard ATX form factor, and come without an integrated CPU or graphics solution. This means both boards are designed for the same generation of AMD processors and will fit in any full-size ATX case without compatibility concerns.

The connectivity story is equally matched. Both offer the full Wi-Fi 7 (802.11be) stack — backwards compatible through Wi-Fi 4 — paired with Bluetooth 5.4, which represents the current mainstream standard for low-latency, stable wireless peripheral connections. Neither board supports aptX audio. On the usability side, both provide dual BIOS, easy BIOS reset, overclocking support, RGB lighting, and an HDMI 2.1 output, and both carry the same 3-year warranty. These are meaningful quality-of-life features for builders — dual BIOS in particular acts as a safety net against failed firmware updates.

The only measurable difference in this group is physical size: the ROG Strix measures 244 × 305 mm versus the Tomahawk Max's 243.8 × 304.8 mm — a gap of just 0.2 mm on each axis that has zero practical significance for case fitting or installation. In summary, this group reveals a virtual tie: the two boards are functionally and dimensionally equivalent across every general specification provided, and neither holds a meaningful advantage here.

Memory:
maximum memory amount 192GB 256GB
RAM speed (max) 8000 MHz 5600 MHz
overclocked RAM speed 8000 MHz 8400 MHz
memory slots 4 4

Supports ECC memory

The Asus ROG Strix B850-A Gaming WiFi and MSI MAG B850 Tomahawk Max WiFi differ in their maximum supported memory capacity. The Asus board supports up to 192GB of RAM, while the MSI board offers a larger maximum capacity of 256GB. Both motherboards feature 4 memory slots and support DDR5 memory, with a dual-channel configuration.

When it comes to RAM speed, the Asus motherboard supports a maximum RAM speed of 8000 MHz, while the MSI board supports a lower maximum of 5600 MHz. However, the MSI board can handle overclocked RAM speeds up to 8400 MHz, slightly higher than the Asus board's overclocked speed of 8000 MHz. Both motherboards do not support ECC memory, ensuring they are geared toward high-performance gaming or general computing rather than enterprise-level error correction.

In summary, while the Asus board offers higher base RAM speed, the MSI board supports a larger memory capacity and can achieve slightly higher overclocked speeds. Both have similar slot and memory channel configurations, with no ECC memory support on either model.

The Asus ROG Strix B850-A Gaming WiFi and MSI MAG B850 Tomahawk Max WiFi differ in several connector specifications. The Asus board features 2 USB 3.2 Gen 1 ports, 4 USB 2.0 ports, and 2 USB 3.0 ports through expansion, while the MSI board offers 4 USB 3.2 Gen 1 ports, 4 USB 2.0 ports, and 4 USB 3.0 ports through expansion. Both motherboards have 4 M.2 sockets, providing ample expansion for storage, and 2 SATA 3 connectors (Asus) vs 4 SATA 3 connectors (MSI), with the MSI board offering more options for traditional storage devices.

The Asus board has 6 fan headers, while the MSI board includes 8 fan headers, providing additional cooling control for users with larger builds or more demanding cooling setups. The Asus board lacks a TPM connector, whereas the MSI board includes one, which could be important for certain security features. Both motherboards lack mSATA connectors and U.2 sockets, so these options are not available for either model.

In summary, while both motherboards have similar M.2 and USB expansion capabilities, the MSI board provides more SATA 3 connectors, additional fan headers, and includes a TPM connector for enhanced security. The Asus board, on the other hand, offers fewer fan headers and lacks the TPM connector.

Expansion slots:
PCIe 4.0 x16 slots 1 1
PCIe 5.0 x16 slots 1 1
PCIe 3.0 x16 slots 0 0
PCIe x1 slots 0 1
PCI slots 0 0
PCIe 2.0 x16 slots 0 0
PCIe x4 slots 0 0
PCIe x8 slots 0 0

The Asus ROG Strix B850-A Gaming WiFi and MSI MAG B850 Tomahawk Max WiFi both offer 1 PCIe 4.0 x16 slot and 1 PCIe 5.0 x16 slot, allowing for high-speed expansion with modern GPUs. However, the Asus board does not have any PCIe x1, PCIe x4, or PCIe x8 slots, limiting its flexibility for additional smaller expansion cards. In contrast, the MSI board includes 1 PCIe x1 slot, which provides the option for adding smaller expansion cards such as network cards or sound cards, but it also lacks PCIe x4 and PCIe x8 slots.

Both motherboards do not include any PCI slots or PCIe 2.0 x16 slots, which are older formats that are not commonly used in modern builds. This makes both boards focused on the more recent PCIe standards, with an emphasis on PCIe 4.0 and 5.0 for high-performance components.

In summary, while both boards feature the same number of PCIe 4.0 and PCIe 5.0 x16 slots, the MSI board provides an additional PCIe x1 slot, which may offer more expansion options for users who require smaller add-in cards. The Asus board does not have this extra flexibility in terms of PCIe x1 expansion, but both boards focus on high-speed, modern expansion options.

Audio:
Signal-to-Noise ratio (DAC) 120 dB 120 dB
audio channels 7.1 7.1
Has S/PDIF Out port
audio connectors 2 2

The Asus ROG Strix B850-A Gaming WiFi and MSI MAG B850 Tomahawk Max WiFi have identical audio specifications. Both motherboards feature a 120 dB signal-to-noise ratio (DAC), which indicates a high level of audio clarity. They also support 7.1 audio channels, providing a rich surround sound experience for users. Additionally, both motherboards are equipped with an S/PDIF Out port for digital audio output, and each offers 2 audio connectors for connecting audio devices such as speakers or headphones.

Since the audio specifications match perfectly between the two motherboards, there are no differences in terms of audio quality or connectivity options for either product.

Storage:
Supports RAID 1
Supports RAID 10 (1+0)
Supports RAID 5
Supports RAID 0
Supports RAID 0+1

The Asus ROG Strix B850-A Gaming WiFi and MSI MAG B850 Tomahawk Max WiFi both support RAID 1, RAID 10 (1+0), and RAID 0 configurations, allowing for flexible storage setups. However, there is a difference in RAID 5 support: the Asus board supports RAID 5, while the MSI board does not. Both motherboards do not support RAID 0+1, meaning that users cannot set up this specific RAID configuration on either board.

In summary, the main difference between the two boards in terms of storage is the inclusion of RAID 5 support on the Asus board, which is not available on the MSI board. Both motherboards support other common RAID configurations like RAID 1, RAID 10, and RAID 0.

Comparison Summary & Verdict

Both boards share a strong common foundation: AM5 socket, B850 chipset, Wi-Fi 7, DDR5, and solid 7.1 audio — making either a capable choice for a modern build. However, their differences point to distinct audiences. The Asus ROG Strix B850-A Gaming WiFi stands out with its USB 3.2 Gen 2x2 port, a dedicated DisplayPort output, RAID 5 support, and higher official RAM speed ceiling of 8000 MHz, appealing to power users who need versatile connectivity and advanced storage options. The MSI MAG B850 Tomahawk Max WiFi counters with a generous 256 GB maximum memory capacity, more SATA 3 connectors, additional fan headers, a TPM connector, and a higher overclocked RAM ceiling of 8400 MHz — making it the stronger pick for workstation builders, content creators, and those planning heavily expanded or cooling-intensive systems.
