Ryzen 7 3800XT is a high-performance processor model.
I observed my Ryzen 7 3800xt not reaching its claimed 4.7GHz under stress. I checked CineBench single, all-core tests, and CPU-Z but still got temps near 72°C max. One core hit around 60°C.
The purpose of the boost is often unclear. Typically, two threads reach 4.5GHZ while all cores operate at 4.275.
I think with PBO I'm reaching about 4.2ghz to 4.4ghz, though one core on the CCX1 is a bit faster. How are your results? Mine are a little below what I'd think is typical for the CPU, but I'm using an older x370 board with DDR3200 at XMP profile and not going over it much. I believe my chipset has a real limit around 3400mhz thanks to its design, even though the BIOS might try to push it up to 3600mhz.
Be honest with Ryzen and especially the Ryzen 3000, overclocking isn't worth it. Allowing PBO and the chip's built-in algorithms to handle things is the optimal choice. Yet there are tools like Clock Tuner by 1usmus that try to extract the highest possible speed from your processor. I've seen reports suggesting it often pushes for more aggressive, less stable overclocks, so be cautious.
