An interesting leak has let us see the key specifications of the Intel Xeon Emerald Rapids, a new generation of professional processors from the chip giant that will arrive after Sapphire Rapids. This means that they will be two generations above the Xeon Ice Lake-SP seriesand will offer significant performance improvements.
The Intel Xeon Emerald Rapids will have the same design as the Sapphire Rapids, which means that Intel will go back to using a design based on “tiles” or interconnected blocks they will be able to work as if it were a monolithic kernel design. We know that Sapphire Rapids will have four interconnected tiles, and Xeon Emerald Rapids will most likely hold that many blocks.
Taking a look at the specifications that have been leaked, and the information that has accompanied it, we discover that the Intel Xeon Emerald Rapids are going to have a configuration of up to 64 cores and 128 threads. Unlike the Alder Lake-S series, a generation of high-performance consumer processors, the Xeon Emerald Rapids will not have a split between high-performance cores and high-efficiency cores. They will only use high performance cores.
This new generation will use socket E, it will have a TDP between 125 and 350 watts, they will be manufactured on the Intel node, they will offer high scalability thanks to their support of configurations of one, two, four and up to eight sockets, they will have the latest acceleration technologies from Intel, including Data Streaming Accelerator, QuickAssist Technology, Dynamic Load Balancer, Advanced Matrix Extension and Intel In-memory Analytics Accelerator.
Each CPU will be able to work with a configuration of Eight-channel DDR5 memory at a maximum of 5,600 MHz if using two modules per channel or 4800 MHz if using one module per channel (one or two DIMMs per channel). The UPI (Ultra Patch Interconnect) system will have a 20 GT/s mode, which is a clear improvement over Sapphire Rapids’ 16 GT/s. The chip giant will also add TDX (Trust Domain Extensions) instructions, which are used in hardware-isolated virtual machines.
Other important details that have been confirmed in that leak are the support of PCIe Gen 5 and the inclusion of numerous security features. We don’t have an exact release date yet, but Intel has been aiming for 2023. Considering the delay that Sapphire Rapids has suffered, it is likely that the Xeon Emerald Rapids will not arrive until the end of said year, provided that everything goes well and there are no further delays in the release of Sapphire Rapids.
