For example, a dedicated "AX51-NVMe" server for 65 euro / month = 73 usd / month gives you: AMD Ryzen 7 3700X Octa-Core (8 physical aka 16 logical cores), RAM: 64 GB DDR4 ECC, NVMe: 2x 1 TB NVMe SSD, unlimited traffic. That's less than half the cost of lightsail per logical core, or less than 1/4 of the cost of lightsail per GB of ECC ram.
