Intel Sierra Forest “Xeon 6E” CPU With 144 Cores & 180 MB Cache Leaks Out Again
Intel's Sierra Forest "Xeon 6E" CPU featuring 144 cores has leaked out once again in a dual-socket configuration just a few weeks ahead of its launch.

It won't be the first time that we have seen Intel's Sierra Forest "Xeon 6E" CPUs appear within the Geekbench 6 database. This new entry is very similar to the last one and shows a 144-core config featuring two CPUs for a total of 288 cores.

This particular chip was once again running on the Beechnut City platform which is the reference evaluation platform featuring a 2S (Dual-Socket) design & supports 32 DDR5 DIMMs. The platform comes with the LGA 4677 socket, offering support for up to 350W CPU TPDs and up to 88 PCIe Gen5 lanes. Sierra Forest is expected to feature TDPs as low as 200W and will come in both 1S and 2S servers. The higher-end 288 core variant will feature support on the LGA 7592 socket platform which comes in the "Avenue City" reference platform.
The particular Intel Sierra Forest Xeon 6E CPU features 144 E-Cores, 144 threads, a base clock of 2.20 GHz, and lots of cache. There's 108 MB of L3, 72 MB of L2, 4 MB of L1 Data & 9 MB of L1 Instruction cache. There's a total of 180 MB cache on this chip.
Since this is a 2S platform we are looking at, two chips were running which is why 288 cores are mentioned instead of 144 but the cache count makes it clear that each chip was a 144 E-Core SKU and not the top 288-core SKU which should be expected a bit later. Additionally, the CPU was running alongside a total of 256 GB of DDR5 memory.
As for the performance, it looks like this particular Intel Xeon 6E Sierra Forest CPU platform is still an early ES design based on single and multi-core performance. It is rather low and while the E-Core architecture should not be compared to the performance-oriented
