ARM is a RISC architecture. RISC stands for Reduced Instruction Set Computing. This means that the CPU has a limited number of instructions it can use. As a result, each instruction runs in a single cycle and the instructions are simpler. Meanwhile, x86 is a CISC architecture, which stands for Complex Instruction Set Computing.
ARM is designed to be smaller, more energy-efficient, and creates less heat.
One problem is that x86 programs can’t run on ARM. Most programming languages can target ARM just fine. Any currently-maintained programs should have few problems. Anything written in Assembly will need to be rewritten to work on ARM though.
There’s also an issue of speed. Since ARM has fewer instructions, developers need to use more instructions.
