On Binary Translation and Its Consequences

Automated excerpt

Binary translation is challenging because x86-64 instructions sometimes don’t map to aarch64 ones in a straightforward manner. Geekbench 7 comes in both aarch64 and x86-64 versions, providing an opportunity to compare performance with binary translation against native aarch64 performance. Performance counter data from various aarch64 cores show roughly similar instruction counts when executing Geekbench 7’s native aarch64 binary, with occasional exceptions.
