== Overview ==


The new Optimized Power Mode can provide up to 20 percent socket power savings with less than 5 percent performance impact for specific workloads. Innovations in air and [[liquid cooling]] can further reduce total data center energy consumption. Each series has a range of different models that can be drilled down to their target use case:
Intel 4th Gen Xeon Scalable processors(Sapphire Rapids)는 2023년 1월 출시된 데이터센터용 프로세서로, AI, 클라우드 컴퓨팅, 네트워킹, 에지 컴퓨팅, 슈퍼컴퓨팅을 위해 설계되었습니다.


* Performance general purpose
=== Summary ===
* Mainline general purpose
 
* Liquid cooling general purpose
* 무엇인가? — Intel 4th Gen Xeon Scalable processors (Sapphire Rapids)
* Single socket general purpose (“Q” Series)
* 왜 필요한가? — 데이터센터 성능, 효율성, 보안, 기능 향상
* Long-life Use (IoT) general purpose (“T” Series)
* 언제 사용하는가? — AI, 클라우드, 네트워킹, 에지, 슈퍼컴퓨팅
* IMDB/Analytics/virtualization optimized (“H” Series)
* 5G/Networking optimized (“N” Series)
* Cloud-optimized IaaS (“P”, “V” and “M” Series)
* Storage and hyperconverged infrastructure optimized (“S” series)
* HPC optimized (i.e., the Intel Xeon CPU Max series)


== General Improvement ==


=== PCI Express Gen5 (PCIe 5.0) ===
== Purpose ==
4th Gen Intel Xeon Scalable processors have up to 80 lanes of [[PCIe]] 5.0—ideal for fast networking, high-bandwidth accelerators, and high-performance storage devices. PCIe 5.0 doubles the


I/O bandwidth from PCIe 4.0,9 maintains backward compatibility, and provides foundational slots for CX
이 문서가 존재하는 이유


=== DDR5 ===
* Goal: Intel 4th Gen Xeon Scalable processors의 제품군, 아키텍처, 성능 특징을 한 곳에서 제공
Improve compute performance by overcoming data bottlenecks with higher memory bandwidth. DDR5 offers up to 1.5x bandwidth improvement over DDR4,10 enabling opportunities to improve performance, capacity, power efficiency, and cost. 4th Gen Intel Xeon Scalable processors offer up to 4,800 MT/s (1 DPC) or 4,400 MT/s (2 DPC) with DDR5.
* Scope: Xeon 모델 카테고리, PCIe 5.0, DDR5, CXL, XCC/MCC/HBM, 내장 가속기
* Non-goals: 이전 세대 Xeon 상세 비교, [[AMD EPYC]] 상세 비교는 별도 문서


=== CXL ===
Reduce compute latency in the data center and help lower total cost of ownership (TCO) with CXL 1.1 for next-generation workloads. CXL is an alternate protocol that runs across the standard PCIe physical layer and can [[support]] both standard PCIe devices and CXL devices on the same link. CXL provides a critical capability to create a unified, coherent memory space between CPUs and accelerators, and it will revolutionize how data center server architectures will be built for years to come


== XCC, MCC, and HBM Variants<ref>https://www.intel.com/content/www/us/en/support/articles/000094640/processors.html</ref> ==
== Key Concepts ==
One of the overlooked areas of 4th generation Xeon product is in the processor line's three main configurations.
