Any more complex code was left to the compiler. The removal of so much circuitry, about  of the transistors in the Motorola 68000 for instance, allowed the CPU to include more registers, which had a direct impact on performance.
Any intricate code was delegated to the compiler, resulting in a considerable decrease in hardware components, roughly equivalent to about half of the transistors in the Motorola 68000 processor. As a consequence, more registers were incorporated into the CPU, leading to a notable improvement in speed.
