Download MSI afterburner, absolutely invaluable for this sort of stuff. Log CPU & GPU temps/utilisation/clock frequency/memory usage, FPS, GPU power/voltage limit. First check for obvious albeit unlikely issues (temps, VRAM leak) then make sure that the 1% lows don't correspond with the GPU core or memory reverting to it's base clock ...then spend £300 on a 5000 series with confidence!
XMP, think you mentioned above.
You didn't mention OS. If windows 10, make sure you've got the Ryzen-specific windows power plan installed. Ryzen 2000 was notorious for not recognising load/demand and sitting there at idle when it should be using it's boost clock.
Can also apply a mild OC (R5 2600 has an unlocked multiplier!) and watch the 1% lows increase (or not!).
B450s had extremely limited BIOS memory so early boards shipped with a UEFI BIOS supporting 1000/2000/maybe-3000 and laterly they came with (or you can flash, super easy, not as daunting as it once sounded) a non-UEFI BIOS which free'd up space for 3000/5000 series profiles.
