1-2 The Power9 Sforza Processor Overview
The P9DSU-C motherboard uses dual Power9 Sforza processors that support 12
or 24 cores per processor with each core running at 4GHz. The 12-core proces-
sor offers up to 8 threads per core (SMT8), and the 24-core processor offers up
to 4 threads per core (SMT4). Utilizing IBM's 14 nm, 17 layer SOI technology,
the Power9 processor dramatically reduces overhead associated with encryption.
It greatly enhances system security, virtual media integration, and remote system
management and monitoring. With the Power9 processor built in, the P9DSU-C
motherboard provides the most dynamic, scalable solution to meet the diverse
needs of large cluster server platforms. This motherboard is especially optimized
for memory-intensive applications and is ideal for use in Cloud/HPC (High-Per-
formance Computing) servers as well as in data centers. The Power9 processor
supports the following features:
•
Up to 24 POWER9 chiplets containing a POWER9 core
•
32+32KB L1 cache per core, 512KB L2 cache per core, 120MB L3 cache per
chip and L4 chache via Centaur chip
•
12 Stage pipeline (5 cycles shorter than Power 8 Pipeline)
•
Enhanced on-chip acceleration with support for Nvidia NVLink 2.0, CAPI 2.0
and OpenCAPI 3.0
•
Direct Attach Memory (Scale Out) and Buffered Memory (Scale Up) options
with 120GB/s bandwidth and 230GB/s bandwidths respectively
•
Support for up to 48 PCI-E V.4 lanes
•
Power ISA v3.0
