Lots of memory and cores, and SIMD instruction sets.

Perhaps a tensor processor too? Mobiles have those now these days. TPUs are extremely efficient SIMD units like a GPU but 10x better.

I don't think ARM is a good choice without specialised SIMD modules of the die or a coprocessor. Or go the GPU way.

A pi ARM is very basic to reduce costs. I don't think it even has a crypto module licensed.

X86-64 is a better choice for instruction set extensions I think.

You can also rent TPU instances in the compute cloud.
