Board Features

The ASUS ROG Strix B550-F Gaming is an ATX motherboard which slots into the mid-range of the AM4 market. It combines a solid feature set with dual PCIe M.2 slots, including one capable of supporting PCIe 4.0 x4 drives, while the other is wired to PCIe 3.0 x4. In addition to this is six SATA ports with support for RAID 0, 1, and 10 arrays. Offering a marked improvement over B450 models in regards to memory performance, the B550-F Gaming Wi-Fi supports DDR4-5100 with a maximum capacity of up to 128 GB across four memory slots. For networking, there's a good quality Intel pairing which includes an I225-V 2.5 GbE Ethernet controller, with an AX200 Wi-Fi 6 module which also allows the use of BT 5.0 devices. The boards PCIe configuration includes a top full-length PCIe 4.0 x16 slot, a full-length PCIe 3.0 x4 slot, and three PCIe 3.0 x1 slots.

Touching on rear panel connectivity, ASUS has included two USB 3.2 G2 ports including a Type-C and Type-A port, as well as four USB 3.2 G1 Type-A and two USB 2.0 ports. For users looking to use compatible Ryzen APUs, there's an HDMI 2.1 and DisplayPort 1.2 output pairing, while there's also a USB BIOS Flashback button which allows users to easily update the board's firmware. The onboard audio is taken care of by a SupremeFX S1200A HD audio codec with five 3.5 mm audio jacks and a single S/PDIF optical output. Users can add to the boards USB with an additional four USB 2.0 ports made available via two front panel headers, as well as a single USB 3.2 G1 Type-A header which adds two more Type-A ports. 

Test Bed

As per our testing policy, we take a high-end CPU suitable for the motherboard that was released during the socket’s initial launch and equip the system with a suitable amount of memory running at the processor maximum supported frequency. This is also typically run at JEDEC subtimings where possible. It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.

While we have been able to measure audio performance from previous Z370 motherboards, the task has been made even harder with the roll-out of the Z390 chipset and none of the boards tested so far has played ball. It seems all USB support for Windows 7 is now extinct so until we can find a reliable way of measuring audio performance on Windows 10 or until a workaround can be found, audio testing will have to be done at a later date.

Readers of our motherboard review section will have noted the trend in modern motherboards to implement a form of MultiCore Enhancement / Acceleration / Turbo (read our report here) on their motherboards. This does several things, including better benchmark results at stock settings (not entirely needed if overclocking is an end-user goal) at the expense of heat and temperature. It also gives, in essence, an automatic overclock which may be against what the user wants. Our testing methodology is ‘out-of-the-box’, with the latest public BIOS installed and XMP enabled, and thus subject to the whims of this feature. It is ultimately up to the motherboard manufacturer to take this risk – and manufacturers taking risks in the setup is something they do on every product (think C-state settings, USB priority, DPC Latency / monitoring priority, overriding memory sub-timings at JEDEC). Processor speed change is part of that risk, and ultimately if no overclocking is planned, some motherboards will affect how fast that shiny new processor goes and can be an important factor in the system build.

    I won't give a dollar to ASUS for an AMD product. They've crapped the bed one too many times at this point.
  • Alim345 - Wednesday, July 22, 2020 - link

    Are higher benchmark scores of some boards are due to default bios configuration or beefier power delivery systems?

    Page 4 - Board Features - "For users looking to use compatible Ryzen APUs, there's an HDMI 2.1 and DisplayPort 1.2 output pairing"

    Correct me if I'm wrong, but I thought this MOBO had an onboard integrated graphics processor thus circumventing the need for a specific Ryzen APU. Given that, could you not use, say, a Ryzen 7 3700X like in your test setup and still take advantage of the onboard HDMI/DP?

    Has anyone read the article before posting? Are anandtech authors paid based on a numer of characters? This article contains multiple typos, and then (which is really irritating) multiple repetitions of the whole sentences across the article. In one place the only change in the whole paragraph that is being duplicated is “AMD” changed to “AM4”.

    You must be new here...

    Has been an ongoing issue for years now.

    It's to be expected when they have no editor.

    Anandtech has been dropping that ball for a good half decade or more. Part of the problem is article and table standardization through the use of prior articles and tables. That invariably results in mistakes when clearing old data before entering new information. Those sorts of errors show up constantly making it very clear there is lots of copy and paste sorts of slapdash happening behind the curtain. Professional writers and good editorial proofing are things you should look elsewhere to find.

    pathetic. With msi x570 tomahawk msrp $210 this board has no chances.
  • danjw - Sunday, August 2, 2020 - link

    I think it would be better to list deltas from ambient in the VRM temperature chart. Since that is the real data, save users from having to do the math in their head. ;-)

    Also, I would really like to see Linux benchmarks added.

    Love it Asus rog makes the best top their boards
