Just a buy a 5600X (or 5600 soonish) if you want a six core.
They can work well on budget motherboards and even quality mobos are not expensive.

Appreciate the efforts, solid work and findings. But I’m a bit lost when it comes to PCIe config, do all these boards have PCIe 4.0? Or is it limited? Is the config the same on each board?

From CPU: PCIe x16 4.0 slot or two (x8)
From CPU: PCIe x4 4.0 to NVMe
(basically all boards support those)

From chipset: x6 4.0
(those can be used for whatever manufacturer wants)

I have not read this yet, but I love this series of in-depth guides. I had been shopping based only on chipset, features, and price, and had no idea that performance could vary so much.

Basically most of these boards will have PCIe 4.0 x 16 for the video adaptor. Some of the premium priced boards will have PCIe 5.0 x16. The video adaptor slots are powered by the CPU.

The additional PCIe slots are mostly PCIe 3.0 x1. The higher priced boards may include a PCIE x16 slot that is wired for PCIE x4 speeds. These slots may either support PCIE 3.0 or 4.0. They are powered from the B660 chipset.

The B660 chipset connects to the CPU via a DMI4 x4 link.

Why isn't there a standards body like JEDEC to handle VRM specifications?

Imagine if RAM makers were to start selling RAM that doesn't work at its rated (JEDEC) speed in motherboards, throttled, and so on.

This kind of grift shouldn't be here.
