Does the ASRock B550 Phantom Gaming 4 support Ryzen 5000 CPUs?

Yes. ASRock lists support for AM4 socket Ryzen 3000, 3000 G-Series, 4000 G-Series, 5000 and 5000 G-Series desktop processors. Check ASRock's CPU support list for your exact model and any required BIOS version.

Does this motherboard have built-in WiFi?

No. It includes one M.2 Key E slot for a WiFi module, so you supply and install the card yourself. Wired networking is handled by the board's onboard LAN.

Do I get PCIe 4.0 for my graphics card?

Yes, on the primary slot. The board has one PCIe 4.0 x16 slot, plus one PCIe 3.0 x16 and two PCIe 3.0 x1 slots. PCIe 4.0 speeds require a compatible Ryzen 3000 or 5000 series CPU.

What memory speed does it support?

ASRock rates the board for DDR4 4733+ MHz when overclocked. Achievable speeds depend on your CPU's memory controller and the specific kit, so verify your RAM against ASRock's memory QVL.

Will an AMD Athlon CPU work in this board?

No. ASRock explicitly states the B550 Phantom Gaming 4 is not compatible with AMD Athlon processors, so plan on a Ryzen 3000-series or newer chip.
