Recent leaks have provided detailed insights into Intel's next-generation Xeon 6 series processors, which include the Granite Rapids and Sierra Forest lines. The Granite Rapids processors will feature up to 128 cores utilizing P-Core architecture based on Redwood Cove cores, which support hyperthreading. In contrast, the Sierra Forest processors will include up to 288 cores, using E-Cores based on Sierra Glen cores without hyperthreading support. Intel's new Xeon 6 series encompasses two distinct packages with different socket specifications—Beechnut City with the LGA-4710 socket and Avenue City with the LGA-7529 socket. These platforms are designed for dual-socket motherboards, with Beechnut City supporting up to 350W TDP and 16 channels per CPU, and Avenue City accommodating up to 500W TDP and 12 channels per CPU.

Hardware leaker YuuKi_AnS has disclosed images and some specifications of the new processors, indicating that the larger Avenue City package can support more pins and has a larger size compared to Beechnut City. Among the disclosed models, the Granite Rapids Xeon 6 6xxxP series is noted to reach up to 128 cores with a 500W TDP and clock speeds varying from 2.0 to 3.2 GHz. The exact size of the L3 cache for these processors has not been confirmed, although a 56-core variant features 288 MB of L3 cache.

The initial launch of the Xeon 6 series is scheduled for this year, with Sierra Forest expected in the second half and Granite Rapids to follow. The specifics of core counts, threads, and cache sizes for various models in the Sierra Forest lineup have also been revealed, ranging from 64 to 288 cores with corresponding increases in cache size and power requirements.

Intel's strategic advancements in the Xeon 6 series aim to enhance computational power and efficiency, positioning these processors to be integral in future high-performance computing environments.
