And RISC-V encodes programs into fewer bytes than X86, so it wins in that regard. But there are still no implementation that have all the other features needed for top performance. There are many factors that affect performance.

"There are many factors that affect performance."

Not only man different features contribute to performance but also that put performance depends so much on use-case. Two CPUs implementing the same arch might each win a benchmark that has a different instruction mix or memory access pattern, etc.
