Well fundamentally all super computers are turing machines. So one can do X while Y can not doesn't really make sense in that context.

However the second-fastest (ARM based Fugaku) absolutely wipes the floor with the fastest in certain tasks due to a difference in interconnect topology. Fugaku futhermore has no GPUs unlike many other super computers and instead a CPU with some vector instructions, leading to a different programming model.

If you are more into specialized hardware, Anton3 is amazing.
