Intel is preparing a new Xeon D-series Code-named “Granite Rapids-D”

Serving as a branch of the Xeon server processors, the Xeon D series primarily targets the server market within the communication and networking sectors. It is particularly suitable for intensive computing environments demanding high performance yet constrained by power consumption and space, thereby posing a challenge to server processors based on the ARM architecture.

According to a report by VideoCardz, Intel is preparing a new rendition of the Xeon D series to supersede the existing Ice Lake architecture products, with the earliest launch anticipated in 2024. The upcoming generation of the Xeon D series incorporates chips codenamed “Granite Rapids-D,” the details of which have been unveiled in Intel‘s recent official instruction set guide.

Fabricated using Intel’s 3nm process, the Granite Rapids-D will come in two versions, the HCC and XCC, each offering different configurations, but both adopting the BGA-4368 socket. The XCC will house two I/O modules, supporting eight-channel memory, while the HCC will only possess one I/O module, supporting four-channel memory. The XCC will provide a greater number of PCIe 4.0/5.0 channels, offering increased flexibility in terms of support for CXL, Ethernet, and accelerators. Conversely, the HCC can only offer basic connectivity options.

The current Xeon D series is equipped with Ice Lake-D chips, launched in February 2022, utilizing the Sunny Cove microarchitecture and the 10nm manufacturing process. It supports three/four-channel DDR4-3200 memory, offering up to 56 PCIe channels and supporting 100Gbe network connections, replacing products based on the Broadwell architecture. There are two versions of this as well. The Xeon D-1700 series offers products ranging from 4 to 10 cores, while the Xeon D-2700 series ranges from 4 to 20 cores, totaling 36 models. The most high-end model is the Xeon D-2799, boasting 20 cores and 40 threads, a base frequency of 2.4GHz, a turbo frequency of 3.4GHz, equipped with 30MB of L3 cache, with a TDP of 129W.
