X11DDW-L/NT User's Manual
1.2 Processor and Chipset Overview
Built upon the functionality and capability of the dual Intel Xeon Scalable-SP and 2nd Gen Intel
Xeon Scalable-SP processors (Socket P) with support of Intel C621/C622 chipsets(Note1),
this motherboard provides superb system performance, ecient power management, and a
rich feature sets based on cutting-edge technologies to address the needs of next-generation
computer users. With support of a 6-channel DDR4 memory controller and up to 28 cores
with Hyper-Threading technology, the X11DDW-L/NT provides maximal performance, system
cooling, and PCI-E capacity. This motherboard is optimized for general purpose server
platforms.
Features Supported by Intel Xeon Scalable-SP Processors
Intel Xeon Scalable-SP processors support the following features:
• Intel AVX-512 instruction support to handle complex workloads
• 1.5x memory bandwidth increased to 6 channels
• Hot plug and enclosure management with Intel Volume Management Device (Intel VMD)
• Rich set of available IOs with increased PCI-E lanes (48 lanes)
• Integrated Intel Ethernet Connection X722 with iWARP RDMA
New features supported by 2nd Gen Intel Xeon Scalable-SP Processors
2nd Gen Intel Xeon Scalable-SP processors support the following features:
• Higher performance for a wider range of workloads with per-core performance increase
• Support of Optane DC Persistent Memory (DCPMM) with aordable, persistent, and
large capacity (Refer to Section 1.8 for details.)
• Up to 2993 MHz memory supported
• Vector Neural Network Instruction (VNNI) support for Accelerate Deep Learning & Arti-
cial Intelligence (AI) workloads
• Speed Select Technology provides multiple CPU proles that can be set in the BIOS.
(This feature is available on select CPU SKUs).
• Seamless hardware security mitigations & performance/frequency exibility
Note 1: The X11DDW-L is supported by Intel C621 chipset, and the X11DDW-NT is
supported by Intel C622 chipset.
Note 2: DCPMM memory and 2933 MHz memory are supported by 2nd Gen Intel Xeon
Scalable-SP processors only.
