A massive roadmap for the Intel Xeon server-grade CPUs has allegedly leaked online. The roadmap appears to show the future of known Intel Xeon Ice Lake, Sapphire Rapids, as well as some unknown generations of processors that Intel is reportedly developing.
Intel Xeon processor roadmap for the next two years has reportedly surfaced online. The roadmap outlines Intel’s plans for the Xeon server-grade processors in every stage of development, including currently shipping, in development, in the planning stage, and even next-generation and concept stages.
Intel Xeon Roadmap Mentions Multiple Stages Of Development And Core Architectures:
Intel recently confirmed its Ice Lake Xeon processors will enter volume production starting from Q1, 2021. The new alleged roadmap outlines which Intel Xeon processors are already [Shipping], [In Development], in [Planning | NextGen], and which are in [Concept] phases. Since the roadmap is primarily for the Xeon server-grade processors, the industries mentioned are HPC (High-Performance Computing) CSP (Cloud Service Providers), Storage as a Service, and other scalable enterprises.According to the roadmap, Intel has no plans to refresh its Walker Pass series, known as Intel Xeon Advanced processors, which are meant for the HPC segment. The HPC segment will have to sustain without an entirely new generation of CPUs at least until the end of 2022.
However, Intel does appear to have a plan to deploy a new HPC/AI oriented Xeon Scalable (Tennesse Pass) series based on Ice Lake-X architecture. Interestingly, the successor to the Tennesse Pass is slated to arrive only a few short months later, called Denali Pass (Eagle Stream), which will be based on Sapphire Rapids architecture. The primary difference between the two generations is the later one, which is based on Sapphire Rapids, will have DDR5 and PCIe Gen 5 support.The Tennesse Pass CPUs are aimed at high-power servers. Meanwhile, the Coyote Pass featuring Ice lake CPUs will go into the mainstream servers. Usually, Intel Xeon server CPUs are designed for dual-socket configuration motherboards. These new CPUs would support up to 32 DIMMs, but the technology used for these memory modules isn’t mentioned. A similar evolutionary leap is also applicable to Coyote Pass, which will be succeeded by Fox Creek Pass just two quarters later with identical I/O support.
