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

Intel's Sierra Forest “Xeon 6E” CPU with 144 cores has once again leaked in a dual-socket configuration just weeks ahead of its launch.

Intel's Sierra Forest “Xeon 6E” CPU leaked with 144 cores, large cache pool as launch closes

This wouldn't be the first time we've seen Intel's Sierra Forest “Xeon 6E” CPUs Geekbench 6 database. This new entry is very similar to the last one and shows a 144 core configuration with two CPUs for a total of 288 cores.

This particular chip was running on one more time. Bechant City Platform which is a reference evaluation platform with a 2S (Dual-Socket) design and supporting 32 DDR5 DIMMs. The platform comes with the LGA 4677 socket, which offers support for up to 350W CPU TPDs and 88 PCIe Gen5 lanes. Sierra Forest is expected to feature under 200W TDP and will come in both 1S and 2S servers. The higher-end 288-core variant will feature support. The LGA 7592 socket platform that falls under the “Avenue City” reference platform..

The special Intel Sierra Forest Xeon 6E CPU has 144 E-Cores, 144 threads, a base clock of 2.20 GHz, and lots of cache. 108 MB of L3, 72 MB of L2, 4 MB of L1 data and 9 MB of L1 instruction cache. The chip has a total of 180 MB of cache.

Since this is a 2S platform we're looking at, there were two chips running, which is why 288 cores are mentioned instead of 144, but the cache count makes it clear that each chip has 144 E-Cores. SKU was not Top 288 Core SKU Which should be expected after a while. Additionally, the CPU was running with a total of 256 GB of DDR5 memory.

As for performance, it seems that this particular Intel Xeon 6E Sierra Forest CPU platform is still an early ES design based on single and multi-core performance. That's pretty low and while the E-Core architecture shouldn't be compared to performance-oriented P-Core designs, we still expect the 144 E-Cores to perform much better than the results posted here. The official launch of these chips is relatively close and is expected to launch this quarter so stay tuned for more information.
