It is running a full transformer type neural network on your cpu, it needs all the speed it can get. It’s because the translation engine requires at least SSSE3.1 instructions[1]. These are translated to wasm SIMD instructions[2] which are only enabled by browsers if the underlying hardware is there to execute these at least somewhat efficient.
