Intel’s 2nd Gen E-Core Solely Xeon CPUs, codenamed Clearwater Forest, are anticipated to characteristic as much as 288 cores with up to date structure.
Intel 2nd Gen E-Core Solely Xeon “Clearwater Forest” CPUs Pack Up To 288 Cores With Improved Structure
The newest data comes from Bionic_Squash who retains the tab on the newest developments on Intel’s upcoming chips. In line with the most recent publish, it appears to be like like we’re getting an early style of what to anticipate from Intel’s 2nd Gen Xeon household primarily based on the E-Core CPU structure. The primary E-Core-only household, codenamed Sierra Forest, is but to launch with a deliberate launch for mid-2024 so primarily based on how early this data is, issues may change as we get nearer to the 2025 launch of Clearwater Forest.
Core depend comparability:
SRF-SP < CWF-SP
SRF-AP = CWF-AP— Bionic_Squash (@SquashBionic) December 1, 2023
With that mentioned, it appears to be like like Intel’s Clearwater Forest will make the most of an up to date model of the Crestmont E-Core structure. This might be the fourth Gen E-Core structure with Gracemonth being the primary which made its debut on Alder Lake and was later reused in Raptor Lake CPUs, Crestmonth which goes to debut within the upcoming Meteor Lake CPUs, and Sierra Glen which is able to debut with Sierra Forest chips.
As for Sierra Glen (for Sierra Forest), the E-Core structure feels quite a bit much like Crestmont which itself is similar to Gracemont with some adjustments right here and there as defined on this article. In Clearwater Forest, we’ll see an optimized model of Crestmont cores from the appears to be like of it. These are mentioned to be barely modified variations of Crestmont so not significantly the Skymont E-Core CPU structure which can be utilized by Lunar Lake and Panther Lake by 2025.
The cores in SRF are barely modified model of Crestmont

IPC uplift must be fairly first rate, there’s additionally fairly huge L3 cache improve on CWF

The Clearwater Forest Xeon CPUs using the up to date Crestmont structure are mentioned to supply as much as 288 cores which is the very same (Max) core depend because the Sierra Forest chips. The distinction is that the Clearwater Forest-SP chips will provide extra cores than Sierra Forest-SP (144 cores) whereas the Clearwater Forest-AP chips will peak out on the identical 288 core depend as Sierra Forest-AP. The IPC can also be mentioned to obtain an honest uplift and one main enchancment for Clearwater Forest goes to be a lot greater L3 caches much like what we have seen on the fifth Gen Emerald Rapids P-Core household.
The Intel Clearwater Forest Xeon CPUs that includes the brand new and up to date E-Core structure will debut in 2025 and make the most of the 18A course of node.
