Intel official announcement 144 core new Xeon!

Intel official announcement 144 core new Xeon!

On the evening of March 29, Intel held a webinar for investors in the Data Center and Artificial Intelligence Division, announcing the Xeon platform roadmap for 2023-2025, including the news of four new products.

First look at the overall roadmap.

Earlier this year, Intel released the fourth-generation Xeon Scalable Platform code-named Sapphire Rapids.

In the fourth quarter of this year, Intel will release Emerald Rapids, confirming for the first time that it will belong to the fifth generation of products.

2024 will be exciting. In the first half of the year, the first pure small-core, Intel 3 process Sierra Forest will be launched, followed by the same Intel 3 process, but Granite Rapids with pure P core. Wire.

In 2025, we will see Clearwater Forest, the process is upgraded to Intel 18A, and the Diamond Rapids that was exposed earlier did not appear on the roadmap this time.

have to say,This timetable is quite tight, especially considering that the fourth generation of Sapphire Rapids Xeon has been delayed for a long time for some reason, which also forced Intel to speed up the pace. It will launch the fourth generation platform in about two years, which is very important for Intel. , which is extremely rare for data center platforms.

Although the fourth-generation Xeon of Sapphire Rapids is a bit late, its influence and appeal are still there.

According to official data, it has won more than 450 system designs, a record high for Xeon.

Among them, more than 200 products from more than 50 manufacturer partners have been shipped and launched, and the scale of the first shipment is also the largest in history. The world’s top 10 cloud service companies will also deploy new platforms within 2023.

  The fifth-generation Emerald Rapids are now sampling and undergoing batch verification, and will be delivered on schedule in the fourth quarter of this year.

It still continues the existing Intel 7 manufacturing process, and there will be no essential changes in the architecture. The focus is to increase the number of cores and improve energy efficiency.

The packaging interface also continues to LGA4677, and existing platforms can be seamlessly upgraded.

In the future, Intel will learn from the hybrid architecture introduced by the 12th/13th generation Core, but it is not a dual architecture, and it will walk on two legs.

One is the performance-optimized P-core performance core design, which can be said to be the traditional route, vigorously improving performance, and continuing to build various accelerators. The product codes all end with Rapids, which is very appropriate as the name suggests.

The second is the E-core energy-efficient core design optimized for energy efficiency. It has more cores, higher throughput performance, and better energy efficiency. It is suitable for the cloud market. The product codes all end with Forest (forest), corresponding to the number of densely packed cores.

Sierra Forest is the first E-core design Xeon, which has already had samples and successfully lit them up.Completed the startup of multiple operating systems within 18 hours, setting a new recordwill be shipped in the first half of next year.

  It will have up to 144 cores (144 threads)——Not as many as 334 and 512 as previously rumored, but not a lot, and will exceed the size of AMD Bergamo’s 128 Zen4c cores.

Come and feel the spectacular scene of densely packed 144 cores running at the same time.


The P-core product that debuted almost simultaneously is Granite Rapids, which will also be delivered within 2024.

Its research and development is also progressing smoothly, and all key engineering nodes have been completed, and the number of cores will continue to increase.

Sierra Forest, Granite Rapids will be upgraded toBrand new Intel 3 manufacturing process (can be understood as 3nm), LGA7529 package interface, share the same platform and many IP, technologywhich naturally helps shorten development and time-to-market.

It is worth mentioning that Granite Rapids has innovative breakthroughs in memory and I/O, especially the memory will support DDR5-8800 MCR RIDMM, and the maximum bandwidth will reach an astonishing 1.5TB/s, which is 83% higher than the current level.

Intel demonstrated a live demonstration of a dual-socket system running DDR5-8000.

continue to the future,Clearwater Forest will be delivered in 2025, introducing the Intel 18A manufacturing process (understood as 1.8nm) for the first time.

Intel will fulfill its promise of “four-year five-generation process nodes” at that time, including 7, 4, 3, 20A, 18A, of which 4 and 20A will not be used on Xeon.

Product details are not disclosed, only know that it is a new generation of E-core, which will definitely greatly increase the number of cores again.

Finally, the overall product layout of Intel data centers and artificial intelligence. In addition to Xeon CPUs, there will also be GPU computing accelerators, AI accelerators, and FPGAs, which cooperate with each other to form the grand blueprint of Intel XPU.

Among them, the Habana Gaudi 3 AI accelerator has completed design certification, or tape-in, but performance details have not been announced.

In 2023, Intel plans to have as many as 15 new FPGA products pass the Production Release Qualification (PRQ) program, which is Intel’s largest new FPGA product release to date.
