ASRock B850 LiveMixer WiFi VS ASRock B850 Pro RS

At their core, the ASRock B850 LiveMixer WiFi and ASRock B850 Pro RS are built on the same foundation: both use the AM5 socket with the B850 chipset, share an identical ATX form factor (244 × 305 mm), support overclocking, include dual BIOS, output via HDMI 2.1, and carry a 3-year warranty. For a buyer evaluating platform capability and longevity, these two boards are effectively interchangeable on paper.

The only meaningful divergence in this group is connectivity: the LiveMixer WiFi includes Wi-Fi and Bluetooth, while the Pro RS has neither. In practice, this is a significant real-world distinction. Without built-in wireless, Pro RS owners who need network access away from an Ethernet port must purchase a separate PCIe or USB adapter — adding cost, consuming a slot or port, and potentially introducing driver complexity. Bluetooth absence also rules out wireless peripherals and audio devices without a dongle.

The LiveMixer WiFi holds a clear edge in this group purely due to its integrated wireless capabilities. Unless a buyer is certain they will always use a wired Ethernet connection and have no need for Bluetooth, the LiveMixer WiFi offers meaningfully broader out-of-the-box connectivity at no sacrifice in platform specs, dimensions, or warranty coverage.

The ASRock B850 LiveMixer WiFi and the ASRock B850 Pro RS both support a maximum memory amount of 256GB, providing ample capacity for demanding applications and workloads. They also share the same number of memory slots, with 4 slots available for RAM expansion, and both motherboards support dual-channel memory configurations, which help optimize performance.

In terms of memory speed, both motherboards support overclocked RAM speeds of up to 8000 MHz, offering significant headroom for high-performance memory setups. Additionally, both products support DDR5 memory, which ensures compatibility with the latest generation of faster and more efficient RAM modules.

Neither the ASRock B850 LiveMixer WiFi nor the ASRock B850 Pro RS supports ECC (Error-Correcting Code) memory, so neither is specifically designed for workloads that require this feature for data integrity.

The ASRock B850 LiveMixer WiFi and the ASRock B850 Pro RS motherboards offer a variety of port options, but there are some differences. The LiveMixer WiFi has 1 USB 3.2 Gen 2 port (USB-A), 4 USB 3.2 Gen 1 ports (USB-A), and 1 USB 3.2 Gen 2 port (USB-C). In comparison, the Pro RS has no USB 3.2 Gen 2 USB-A ports, but it matches the LiveMixer WiFi with 4 USB 3.2 Gen 1 USB-A ports and 1 USB 3.2 Gen 2 USB-C port. Additionally, the Pro RS offers an extra USB 3.2 Gen 1 USB-C port, which the LiveMixer WiFi lacks.

For USB 2.0 ports, the LiveMixer WiFi has 8, while the Pro RS has 6. Both motherboards have no USB 3.2 Gen 2x2, USB 4 40Gbps, or USB 4 20Gbps ports, and neither includes Thunderbolt 3 or 4 ports.

In terms of display outputs, the LiveMixer WiFi includes 1 HDMI output and 1 DisplayPort output, while the Pro RS only has an HDMI output. Both motherboards feature 1 RJ45 Ethernet port and lack PS/2, eSATA, DVI, or VGA connectors.

Both the ASRock B850 LiveMixer WiFi and the ASRock B850 Pro RS motherboards offer a solid selection of connectors. For USB ports through expansion, both products support 4 USB 3.2 Gen 1 ports, 1 USB 3.2 Gen 2x2 port, and 4 USB 2.0 ports. The two motherboards also support 4 USB 3.0 ports through expansion. The major difference comes in the number of SATA 3 connectors: the LiveMixer WiFi has 2, while the Pro RS has 4.

When it comes to fan headers, the LiveMixer WiFi includes 6, while the Pro RS has 7, giving the Pro RS slightly more options for cooling setups. The LiveMixer WiFi supports 3 M.2 sockets, while the Pro RS offers 4, providing more flexibility for adding high-speed storage devices on the Pro RS.

Both motherboards have a TPM connector, ensuring compatibility with trusted platform modules for security, but neither includes U.2 or mSATA connectors. Additionally, neither product supports SATA 2 connectors.

The ASRock B850 LiveMixer WiFi and the ASRock B850 Pro RS both offer a variety of PCIe slots, but there are differences in the number of PCIe x16 slots. The LiveMixer WiFi has 2 PCIe 4.0 x16 slots and 1 PCIe 5.0 x16 slot, whereas the Pro RS has 1 PCIe 4.0 x16 slot and 1 PCIe 5.0 x16 slot. This gives the LiveMixer WiFi more PCIe 4.0 x16 slots for additional expansion cards like GPUs or other high-performance peripherals.

Both motherboards lack PCIe x1, PCI, PCIe 2.0 x16, PCIe x4, and PCIe x8 slots, which means that their expansion options are focused primarily on the x16 slots. Additionally, neither motherboard offers PCIe 3.0 x16 slots, making both models suitable for modern systems relying on PCIe 4.0 and 5.0 for high-speed connections.

In summary, the primary difference in expansion slots is that the LiveMixer WiFi offers more PCIe 4.0 x16 slots compared to the Pro RS, which only has one. Both motherboards, however, provide a similar set of options for high-speed expansion through PCIe 5.0 x16 slots.

Both the ASRock B850 LiveMixer WiFi and the ASRock B850 Pro RS motherboards support 7.1 audio channels, delivering high-quality surround sound. However, there is a difference in the audio connectivity features. The LiveMixer WiFi includes an S/PDIF Out port, which allows for high-quality digital audio output to external devices. In contrast, the Pro RS does not feature an S/PDIF Out port.

In terms of audio connectors, the LiveMixer WiFi offers 2 connectors, while the Pro RS provides 3 connectors, giving the Pro RS slightly more flexibility for connecting external audio devices.

Overall, while both motherboards support the same audio channel configuration, the LiveMixer WiFi has the advantage of an S/PDIF Out port, whereas the Pro RS offers an extra audio connector for more device connections.

Both the ASRock B850 LiveMixer WiFi and the ASRock B850 Pro RS motherboards support RAID 1 and RAID 10 (1+0), allowing for redundancy and performance in storage configurations. They also both support RAID 0, which enables faster read and write speeds through striping. However, there is a difference in RAID 5 support. The LiveMixer WiFi supports RAID 5, providing a balance of redundancy and storage efficiency, while the Pro RS does not support RAID 5.

Neither motherboard supports RAID 0+1, which is a combination of RAID 0 and RAID 1.

In summary, while both motherboards support essential RAID configurations like RAID 1, 10, and 0, the LiveMixer WiFi has the added capability of RAID 5, making it more versatile for certain storage setups compared to the Pro RS.
