AM4 · Zen 2 · 8 Cores / 16 Threads · All-Rounder
The AMD Ryzen 7 3700X brought 8 cores and 16 threads to the mainstream at a price point that disrupted the market. With a 65W TDP and boost clocks up to 4.4 GHz, it's efficient, capable, and still handles modern games and productivity workloads respectably.
Running on AM4, the 3700X works with B550 and X570 motherboards. B550 is the sweet spot for most builders, adding PCIe 4.0 support at a reasonable price. X570 boards offer more PCIe 4.0 lanes and additional USB connectivity, making them better for workstation use with multiple NVMe drives.
The 3700X's efficient 65W TDP means even basic B550 boards run it effortlessly. Consider upgrading the CPU to a Ryzen 5 5600X (better gaming) or Ryzen 7 5800X (better multi-threaded) on the same board — AM4's best value proposition.
12+2+1 phases · 2.5G LAN · 2x M.2 · Upgrade-ready
The B550 Tomahawk is the perfect match for the 3700X. The 12+2+1 VRM laughs at the 3700X's modest power requirements and leaves massive headroom for a future Ryzen 5000 upgrade. 2.5G LAN, 2x M.2 (one PCIe 4.0), and excellent build quality make this the default recommendation for any AM4 build.
14+2 phases · WiFi 6 · 2.5G LAN · Premium audio
The premium B550 choice for the 3700X. WiFi 6, 2.5G LAN, ALC4080 audio, and a 14+2 VRM deliver a flagship experience without the flagship price. The Strix build quality and ASUS BIOS make it a joy to configure and use daily. Perfect for the 3700X and any future AM4 upgrade.
16+2 phases · Fanless X570 · WiFi 6 · 2.5G LAN
If you need X570's extra PCIe 4.0 lanes for multiple NVMe drives or are building a workstation, the Dark Hero is the ultimate AM4 board. The fanless X570 chipset cooling, exceptional 16+2 VRM, WiFi 6, 2.5G LAN, and passive design make it whisper-quiet. Overkill for the 3700X, but perfect if you plan to upgrade to a 5950X later.
12+2 phases · 2.5G LAN · 2x M.2 · Great price
Outstanding bang for the buck. The 12+2 VRM is more than the 3700X needs, 2.5G LAN is a premium touch at this price, and 2x M.2 covers your storage. No-frills, reliable, and affordable — leaving more budget for your GPU and RAM.
Micro-ATX · 10+2 phases · 2x M.2 · Unique design
The go-to Micro-ATX B550 board with style. The 10+2 VRM runs the 3700X without issue, 2x M.2 provides fast storage, and the distinctive design sets it apart from bland budget boards. Great for compact builds where space is at a premium.
