History
Predecessor(s)POWER9

The processor is designed to have 15 cores available, but a spare core will be included during manufacture to cost-effectively allow for yield issues.

Power10-based processors will be manufactured by Samsung using a 7 nm process with 18 layers of metal and 18 billion transistors on a 602 mm2 silicon die.

The main features of Power10 are higher performance per watt and better memory and I/O architectures, with a focus on artificial intelligence (AI) workloads.
