Intel 14th Gen Specs: Only 6 P-Cores on Meteor Lake Desktop CPUs, 2nm Arrow Lake-S with 8P+8E Cores [Rumor]

The (alleged) specifications of Intel’s 14th Gen lineup have surfaced (via: WCCFTech) for the first time. Divided into two sub-families leveraging different process nodes and core architectures, it’ll mark a defining shift in the chipmaker’s design philosophy. Roughly four years following the launch of rival AMD’s first chiplet-based design (Ryzen 3000), Intel will release its first modular chips in the consumer space. In addition, the 14th Gen family, comprising the Meteor and Arrow Lake offerings, will come with a new “V” socket, blocking, mandating that users buy a new set of motherboards.

Meteor Lake is slated for a mid to late 2023 release. It’ll leverage five disaggregated dies, fabbed on the Intel 4 (CPU tile), TSMC N5 (iGPU tile), TSMC N6 (SoC and I/O tiles), and the Intel 16 (Foveros Base Die):

CPU Tile	Intel 4
3D Foveros Base Die	22FFL/Intel 16
GPU Tile	TSMC 5nm (N5)
SoC Tile	TSMC 6nm (N6)
I/O Tile	TSMC 6nm (N6)

The first is the K-series die with a base and boost TDP of 125W and 254W, respectively. Then, there’s the non-K SKU with a 65W base power and the low-power T-series chip running at 35W (stock). The core counts of the five Meteor Lake-S dies are as follows:

• Meteor Lake-S (K): 22 Cores (6P + 16E)
  • TDP: 125W
• Meteor Lake-S (non-K): 22 Cores (6P + 16E)
  • TDP: 65W
• Meteor Lake-S (T): 22 (6P + 16E)
  • TDP: 35W
• Meteor Lake-S (non-K): 14 Cores (6P + 8E)
  • TDP: 65W
• Meteor Lake-S (T): 14 Cores (6P + 8E)
  • TDP: 35W

Meteor Lake-S will top out at 22 cores, two less than Raptor Lake. The P-core count will be reduced to 6 (from 8), keeping the E-core counts unchanged at 16. Redwood Cove will succeed Raptor Cove/Golden Cove as the P-core, and Crestmont will be the successor to Gracemont. Meteor Lake will land in mid or late 2023, followed by Arrow Lake towards the end of 2024.

Arrow Lake will leverage the 20A (2nm) process node. It’ll scale the P-core back to 8 or 24 when factoring in the E-cores. The 14th Gen lineups will utilize Intel’s Foveros 3D packaging technology. Unlike the first implementation of Foveros, Meteor Lake will feature a dummy base tile (interposer) without any logic. The four functional chiplets or tiles will be 3D stacked atop this skeleton die.

• Arrow Lake-S (K): 24 Cores (8P + 16E)
  • TDP: 125W
• Arrow Lake-S (non-K): 24 Cores (8P + 16E)
  • TDP: 65W
• Arrow Lake-S (T): 24 Cores (8P + 16E)
  • TDP: 35W

Meteor Lake and Arrow Lake will both feature a 4-core Xe iGPU die for a total of 512 ALUs, nearly the same as the A310. While this shouldn’t pose much of a challenge to the Ryzen mobile APUs, the desktop-grade parts might end up being slower.
