2nd Generation Intel® Xeon® Scalable Family Ready

GIGABYTE's servers are fully ready to support the second generation of Intel® Xeon® Scalable Family processors, codenamed "Cascade Lake", which bring the following major enhancements:

• Intel® Optane™ DC Persistent Memory: Built-in support for this revolutionary new product based on Intel's 3D Xpoint technology
• Overall Performance: Higher CPU frequencies, improved turbo profiles vs. prior-gen Intel Xeon Scalable processors
• Increased DDR4 Memory Speed & Capacity: Up to 2933MHz (1 DIMM per channel on some SKUs), 16Gb based DIMM supported
• Intel Deep Learning Boost: Significantly accelerates inference performance for deep learning workloads optimized to use VNNI (Vector Neural Network Instructions)
• Security: Hardware mitigations for Meltdown / Spectre security vulnerabilities

Intel® Xeon® Scalable Family Processors

GIGABYTE's Intel® Xeon® Scalable Processor family servers are available in dual socket configurations, and are compatible with the full family of different SKUs (Bronze, Silver, Gold and Platinum) that are workload optimized to support different applications, from enterprise IT database, cloud and storage to the most high-demand HPC workloads.

Advanced features built into the silicon include:

• Intel® QAT: Speed up data compression and cryptography with integrated Intel QuickAssist Technology (QAT).
• Intel® AVX-512: Intel Advanced Vector Extension 512 instruction set architecture enables workload-optimized performance and throughput increases for advanced analytics, high performance computing (HPC) applications, and data compression.
• Intel® VROC: Intel Xeon Scalable Processors come with built-in support for Intel VROC (Virtual RAID on CPU). And GIGABYTE Intel Xeon Scalable NVMe SKU servers all ship with an Intel VROC module as standard.
• Intel® Omni-Path: Selected GIGABYTE servers support CPU SKUs with integrated Intel Omni-Path Fabric connection

Intel® Optane™ DC Persistent Memory Ready

GIGABYTE's second generation Intel® Xeon® Scalable family servers come ready to support Intel Optane DC Persistent Memory, a revolutionary new product that re-defines traditional memory & storage architectures by enabling a large persistent memory tier between DRAM and SSDs, that's higher capacity than DRAM and faster than SSDs, enabling the user to bring more data closer to the CPU for faster time for insight.

Optane DC Persistent Memory Modules ("DCPMM") integrate seamlessly into existing DDR4 DIMM slots, and use Intel's 3D Xpoint memory technology, which unlike DRAM retains data after power is removed. The modules will be available in capacities up to 512GB - a massive increase compared to the current maximum 128GB of industry-leading DDR4 memory sticks - and can be addressed by the OS or application either as memory (Memory Mode) or storage (Application Direct Mode).
