The M1 family of chips all share the same basic CPU core. More cores mean that the processor is faster. The base M1 has 8 cores. The M1 Pro and M1 Max have 10 cores. The M1 Ultra has 20 cores (Max x 2). The Max and Ultra also have a greater number of GPU cores for graphics processing than the M1 or M1 Pro.
When the M2 family of chips are released, they will also all share the same basic core but it will be a little faster and more efficient than the M1 cores. That means that each M2 version will be a little faster than their M1 equivalent, but the Pro/Max/Ultra of M1 will still be faster than the M2.
Think of them like car engines.
- The M1 is a 4-cylinder engine car.
- The M1 Pro is a 6-cylinder engine car.
- The M1 Max is an 8-cylinder engine car.
- The M1 Ultra is a 16-cylinder engine car.
Next year, the manufacturer improves the tuning so that the engines run little faster. that is the M2. The M2 engine runs faster than the M1 engine but still can’t beat the M1 Pro engine.
