No, not all M.2 slots are identical in speed. Their performance can vary based on the manufacturer and specific model.

I've been trying to understand this a bit. I just changed the motherboard in my PC to an ASRock X570 Steel Legend, which has two M.2 slots. I prefer using the one below the GPU over the one right behind it. But I'm curious—are both slots the same speed?

The motherboard port with chipset lanes experiences greater delay because it includes PCIe connections not linked directly to the processor. This means the corresponding CPU port tends to be quicker in practice (though the gap might be minor). According to the manual, the CPU port generally offers the optimal choice, often being the highest quality option due to its proximity.
