Tango uses state of the art optimizations to minimize the overhead of binary translation. The Technology page describes these optimizations in more detail.

In this page we present a few benchmark results which show the performance of Tango v2.0.0. We run the benchmark on CPUs supporting both 32-bit and 64-bit ARM to allow for a fair comparison. All benchmarks were compiled as 32-bit ARM code and the resulting binaries were run with Tango enabled ("Translated") and disabled ("Native").

Note that newer ARM cores such as the Neoverse V1 and Cortex-X1 have highly optimized AArch64 execution. For example, on the Pixel 6's Cortex-X1, Geekbench 5 runs 40% faster in 64-bit mode than in 32-bit mode. As such, Tango translated code can take advantage of this and deliver better performance than original 32-bit code. When this happens, the performance gains are shown as positive percentages in Geekbench scores and negative percentages in SPEC run time differences.
