Intel 144 Core Sierra Forest Xeon CPU Leaks Out: Powered By Sierra Glen E-Core Architecture, 172 MB Cache

wccftech.com:

Intel's next-gen Sierra Forest Xeon CPU featuring a mighty 144 E-cores has been leaked within the Geekbench database.

Intel has given us a lot of details on its Sierra Forest Xeon CPUs which will be packing the Sierra Glen E-Core. This E-Core is an optimized version of the Crestmont core that will be incorporated within Meteor Lake & Arrow Lake client CPUs. The CPUs will come in 144 SP and 288 AP configs.

Now, we have the first appearance of the 144-core variant showing up within the Geekbench 6 benchmark database. This particular chip was running on the Beechnut City platform which is a reference evaluation platform featuring a 2S (Dual-Socket) design and 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 particular Intel Sierra Forest Xeon CPU features 144 E-Cores, 144 threads, a base clock of 2.20 GHz, and lots of cache. There's 108 MB of L3, 64 MB of L2, 4 MB of L1 Data & 9 MB of L1 Instruction cache. 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 Sierra Forest CPU platform was 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 P-Core designs, we still expect 144 E-Cores
