Intel's Granite Rapids-D Xeon CPUs officially surface for the first time, according to a support document obtained by the media outlet Computer Base.
Intel Granite Rapids-D to Feature Intel 3 Manufacturing Process With Significant Performance Uplifts
Update: The renowned leaker @yukki_ans has uploaded what seems to be a die configuration of the upcoming Granite Rapids-D lineup, and interesting details have been revealed.
The Granite Rapids-D are expected to come in two different variants. The HCC (High Core Count) model will comprise a single LCC die and IO die with support for four memory channels. The Granite Rapids-D XCC will offer a single HCC die and 2 IO dies, allowing support for additional ethernet and accelerator capabilities. The XCC variant will also support up to eight memory channels.
Original Story: For those unaware, the Xeon D processors are currently under the Ice Lake-D lineup, and the new Granite Rapids-D family is expected to replace Ice Lake. Moreover, it is revealed that the upcoming processors will be based on Intel 3 fabrication technology, which comes with various improvements in crucial data center applications such as high-performance libraries. The Intel 3 process node has generational optimization, providing an 18% performance per watt gain from Intel 4.
Generally, the Intel Xeon D lineup doesn't feature a high core count and is suited for less-intensive applications when compared to running databases. They are ideal for home networking and computing use. Apart from the Granite Rapids-D, Intel is also expected to release two other variations, Granite Rapids-AP and Granite Rapids-SP, which were recently pictured in two different leaks.
The Intel 6th Gen Granite Rapids-SP/AP CPUs CPUs will utilize different chip designs. The Granite Rapids-SP/AP chips will also be based on the "Intel 3" process node and take advantage of the brand-new Redwood Cove cores, which are expected to deliver a significant performance uplift over existing Golden Cove and Raptor Cove P-Cores. The Granite Rapids-D will also be using the same Redwood Cove P-cores used by the rest of the two Granite Rapids families.
The actual release date for the upcoming Granite Rapids-D lineup isn't specific yet, although it is expected to release around the end of 2024. The standard Granite Rapids-SP Xeon CPUs are also expected to launch in the second half of 2024, whereas the E-Core-only Sierra Forest will launch in the first half of 2024. Expect more information in the coming months.
