  • Intel is not expected to offer vPro support for any Wildcat Lake SKU.
  • The Core 3 305 model is a newly reported addition to the lineup, distinct from the previously mentioned Core 3 304.

Intel Nova Lake-HX Enthusiast Laptop Processors (Unconfirmed Leaks)

Overview

A series of leaks, primarily attributed to leaker Jaykihn, have detailed the core configurations for Intel's upcoming Nova Lake-HX enthusiast laptop platform. This platform is expected to launch around CES 2027.

Reported CPU Configurations

Die SKU P-Cores (Coyote Cove) E-Cores (Arctic Wolf) LP-E Cores Total Cores iGPU (Xe3P / Celestial) Reported TDP Nova Lake-HX 8 16 4 28 2 Core ~55W Nova Lake-HX 4 8 4 16 2 Core ~55W Nova Lake-H 4 8 4 16 12 Core ~28W Nova Lake-H 4 8 4 16 4 Core ~28W Nova Lake-U 4 0 4 8 4 Core ~28W Nova Lake-U 2 0 4 6 2 Core ~15W

Key Architectural Details from Leaks

  • Architecture: The Nova Lake-HX will use "Coyote Cove" P-cores and "Arctic Wolf" E-cores (though other leaks mention "Darkmont" E-cores for desktop).
  • Compute Tile: The Nova Lake-HX is expected to use a single compute tile, attributed to power constraints and manufacturing costs in mobile form factors. This contrasts with the desktop Nova Lake-S, which is rumored to use dual compute tiles with up to 52 cores.
  • Power Efficiency: A key improvement will be the inclusion of dedicated Low Power E-cores (LPEs) on the SoC Tile, which was absent in the Arrow Lake-HX series, to enhance power efficiency.
  • Graphics: The iGPU will use the refined Xe3P (Celestial) architecture. The SoC Tile will also house next-generation Xe4 (Druid) Media and Display engines.

Competition and Future Platforms

  • AMD's anticipated competitor is the "Gator Range" processor, with leaks suggesting up to 24 Zen 6 cores across two CCDs.
  • Beyond Nova Lake, Intel's Razer Lake-AX platform is identified as a future competitor to AMD's Halo-class APUs.
  • The Razer Lake-AX platform may potentially integrate Intel's x86 core architectures with NVIDIA's RTX GPUs in custom SoCs.

Intel Xeon Diamond Rapids and Coral Rapids (Unconfirmed Leak)

A separate leak from Jaykihn on social media has provided details on Intel's next-generation Xeon server processors:

  • Diamond Rapids: Planned for a mid-2027 launch. It will be the last Xeon lineup without Simultaneous Multithreading (SMT). It is expected to scale up to 256 cores initially, with a peak of 512 cores via a compatible 16-channel platform.
  • Coral Rapids: Planned for a mid-2028 launch, which is expected to bring back SMT for 8-channel platforms.
