The state of SIMD in Rust in 2026
A lot of progress was made since last year, and I made some of it! After [last year's survey](https://shnatsel.medium.com/the state of simd in rust in 2025 32c263e5f53d) I started contributing to the SIMD library that seemed the most promising. One thing led to another, and now I'm a maintainer of Fearless SIMD. To avoid a conflict of interest, I invited authors of other libraries ( std::simd , wide , pulp , macerator ) to review and provide feedback on a draft of this article.

When to choose x86-64 vs aarch64
Not all cloud vCPUs are created equal. When you create a PlanetScale Postgres or Neki database, you have to choose between `aarch64` (ARM) and `x86-64`. Two clusters on different architectures can have the same vCPU count and RAM, yet perform very differently. It's worth understanding the implications, since you can't easily switch the CPU architecture on your cluster later. x86 grew up on the desktop, prioritizing backward compatibility and performance. It began at Intel in 1978 and IBM’s…
