No, 64K is definitely not loaded in 1 load operation. Maximum amount of load operations modern CPUs can do is 2x512-bit or 128 bytes per cycle or around ~600 GB

That said, there is no universal page size one can choose from. Some workloads will benefit from smaller page size while others will benefit from larger page size but 512K is not the size you will want to choose. Read-, write-, space-amplification, CPU cache thrashing etc.
