Quite meek compared to a year 2018 PC (2 years old)
CPU: Easily OC >5GHz
GPU: RTX 2080 14.2 teraflops
RAM: 64GB
The PS5 had custom hardware design and chipsets that push the throughput limit of the SSD. Cannot compare with PC components that all connected to limited bandwidth buses that need to cater for $10 cards all the way to $3K cards plus running on general purpose bloated OS.
You should go watch the Road to PS5 to understand more on the custom hardware architecture.
