The real reason is that ARM publishes the detailed pipeline documentation that I need, so squeezing out every last cycle for ARM is fun, while Intel hides the pipeline documentation, so squeezing out every last cycle for Intel is painful." https://blog.cr.yp.to/20140517-insns.html https://blog.cr.yp.to/20140517-insns.html
