Power10 is a superscalar, multithreading, multi-core microprocessor family, based on the open source Power ISA, and announced in August 2020 at the Hot Chips conference; systems with Power10 CPUs. Generally available from September 2021 in the IBM Power10 Enterprise E1080 server.

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.[1][2][3][4]

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.[5]
