Intel Sierra Forest “Xeon 6E” CPU With 144 Cores & 180 MB Cache Leaks Out Again

Intel’s upcoming Sierra Forest “Xeon 6E” CPU has once again made an appearance, this time in a dual-socket configuration just weeks before its official launch. Let’s dive into the details of this powerful processor.

Key Specifications:

• Cores: The Sierra Forest “Xeon 6E” CPU boasts an impressive 144 E-Cores.
• Threads: It supports 144 threads for parallel processing.
• Base Clock: The base clock speed is 2.20 GHz.
• Cache: The chip features a whopping 180 MB of cache:
  • L3 Cache: 108 MB
  • L2 Cache: 72 MB
  • L1 Data Cache: 4 MB
  • L1 Instruction Cache: 9 MB

Platform Details:

• Beechnut City Platform: The CPU was tested on the Beechnut City platform, which is a reference evaluation platform with a 2S (Dual-Socket) design. It supports 32 DDR5 DIMMs and utilizes the LGA 4677 socket. The platform can handle up to 350W CPU TPDs and offers 88 PCIe Gen5 lanes.
• Memory: The test configuration included a total of 256 GB of DDR5 memory.
• Expected TDPs: Sierra Forest CPUs are expected to have TDPs as low as 200W and will be available for both 1S and 2S servers.
• High-End Variant: The higher-end variant of the Sierra Forest CPU, featuring 288 cores, will support the LGA 7592 socket platform (known as the “Avenue City” reference platform).

Performance:

• The leaked Geekbench results indicate that this particular Intel Xeon 6E Sierra Forest CPU is still in the early engineering sample (ES) stage. Both single-core and multi-core performance appear to be relatively low.
• While the E-Core architecture isn’t directly comparable to performance-oriented P-Core designs, we expect the 144 E-Cores to perform better than the posted results.
• The official launch of these chips is expected within this quarter, so stay tuned for more information.
