The whole point of the 550/520 is guaranteed out-of-the-box support for 4000-series CPUs. With B450, you are limited to boards that explicitly state out-of-the-box support on the box or have BIOS flashback function for CPU-less BIOS update.The whole point of 500 series mobo's is PCIe 4.0 support, without that, I don't see a reason to consider this over a B450 board.
This is true. Most of the Zen 2 chips runs best when we leave it to run at stock with PBO on. In my experience, performance actually regressed when I overclocked a Zen 2 chip.No overclocking isn't exactly a deal breaker. PBO does a good enough job, that overclocking Ryzen 3000 is a waste of time, anyway.
So, given the B450 now will have support for 4000 series CPU's, if the A520 doesn't support PCIe 4.0, what exactly is the point of considering it over B450? The whole point of 500 series mobo's is PCIe 4.0 support, without that, I don't see a reason to consider this over a B450 board.
If it never had overclocking how would you explain this thenA series never had overclocking
