There are plenty of AMD based laptops that outperform the M1's. The M1 isn't about best performance but best battery life vs x86 offerings.
Then why do you have a 9900K? Obviously the M1 can't do certain things the 9900K machine can do, including 8TB SSD. I highly doubt the M1 would outperform the 9900K but I can't find any benchmarks since the M1's are always compared to other laptops, for good reason.
There is no 13 or 14 inch AMD laptop that outperforms a loaded 14in M1 Max system. Especially not when taking into account overall CPU, GPU, SSD, and RAM performance. If you want the fastest 13 or 14 inch laptop in the world, you've only got once choice - Apple.
