Intel Next-Gen Core Leaks Out, Xeon AP Server CPU to Pack Greater than 128 Cores [Rumor]

The next-generation Intel core architecture may have been leaked out, and it’s named SSHPmont. If true, it’s a change from the usual naming scheme. From Tre to Grace to SSHP. Sounds too secret-y, and may simply be a placeholder. Either way, these SSHPmont cores will power the Sierra Forrest-AP processors, Intel’s absolute high-end SKUs for cloud providers. The previous Xeon AP lineup was Cascade lake AP which basically “glued” two Cascade Lake dies on a single BGA-5903 substrate.

In the end, though, Cascade Lake-AP didn’t get enough traction from cloud providers and was largely shelved. That’s one of the reasons why we saw no AP solution with Ice Lake-S. The Sierra Forest processors are designed for the Birch Stream-AP (BHS-AP) platform, with a launch expected in early 2024. It will reportedly leverage the LGA 7529 socket with a whopping 7,529 pins. In comparison, AMD’s next-Gen Epyc Genoa platform will be based on an LGA 6096 socket.

From what we know, Sierra Forest will be preceded by the Birch Stream platform in early 2023, consisting of Granite Rapids in both SP and AP variants. These will be the first chips from Intel fabbed on the 7nm process (now Intel 4 node). It’s after these two lineups that we expect to see SF, so it’s a long way away, and at this point, it’s mere speculation.

According to MLID, Emerald Rapids-SP or the 5th Gen Xeon Scalable processors will feature the Raptor Lake cores, fabbed on Intel’s 7 node (10nm ESF). The transition from Golden to Raptor Lake can be thought of as that between Sunny to Willow Cove, except it’ll actually improve the IPC a bit. The core count is expected to increase from 56 on Sapphire to 64 on Emerald Rapids, plus improved I/O and higher boost clocks.
