Intel Xeon "Sapphire Rapids" to be Quickly Joined by "Emerald Rapids," "Granite Rapids," and "Sierra Forest" in the Next Two Years
Intel's server processor lineup led by the 4th Gen Xeon Scalable "Sapphire Rapids" processors face stiff competition from AMD 4th Gen EPYC "Genoa" processors that offer significantly higher multi-threaded performance per Watt on account of a higher CPU core-count. The gap is only set to widen, as AMD prepares to launch the "Bergamo" processor for cloud data-centers, with core-counts of up to 128-core/256-thread per socket. A technologically-embattled Intel is preparing quick counters as many as three new server microarchitecture launches over the next 23 months, according to Intel, in its Q4-2022 Financial Results presentation.
The 4th Gen Xeon Scalable "Sapphire Rapids," with a core-count of up to 60-core/120-thread, and various application-specific accelerators, witnessed a quiet launch earlier this month, and is shipping to Intel customers. The company says that it will be joined by the Xeon Scalable "Emerald Rapids" architecture in the second half of 2023; followed by "Granite Rapids" and "Sierra Forest" in 2024. Built on the same LGA4677 package as "Sapphire Rapids," the new "Emerald Rapids" MCM packs up to 64 "Raptor Cove" CPU cores, which support higher clock-speeds, higher memory speeds, and introduce the new Intel Trust Domain Extensions (TDX) instruction-set. The processor retains the 8-channel DDR5 memory interface, but with higher native memory speeds. The chip's main serial interface is a PCI-Express Gen 5 root-complex with 80 lanes. The processor will be built on the last foundry-level refinement of the Intel 7 node (10 nm Enhanced SuperFin); many of these refinements were introduced with the company's 13th Gen Core "Raptor Lake" client processors.
