The Julia version on your M1 Pro might be even quicker than my creaky old Xeon 🙂

We’ve seen benchmarks where the M1 is 2x-3x faster, even using all my 40 cores vs M1’s 8 cores

And then there’s also this accelerator ([Apple M1 GPU from Julia?](https://discourse.julialang.org/t/apple-m1-gpu-from-julia/69563)) that can further speed up linear algebra at least 4x on my machine (see code below). Would be interesting to see if Apple Silicon processors will start to get used in HPC clusters as some points. Historically, Apple didn’t seem to be interested in this but who knows. Presumably, there’re applications where you can use multicore computation instead of single core or multithreading where 40 core Intel(R) Xeon(R) will o…
