Intel Arrow Lake-S Desktop CPU Leaks Surface: 8P+16E Core Configuration Spotted

Intel arrow lake data leaks surface

The world of desktop computing is on the brink of a significant evolution with the upcoming release of Intel’s Arrow Lake-S CPUs. This next-generation platform promises to redefine performance standards, offering a blend of high-efficiency cores and cutting-edge technology.

Let’s hope the IPC jump in the final silicon seems substantial, like from Nehalem to Sandy Transitioning.

Intel’s initial decision to exclude APO support for its 12th and 13th Gen CPUs was met with significant backlash. Despite these CPUs sharing similar architectural (Gracemont E-Cores) traits with the 14th Gen CPUs, Intel confirmed in November 2023 that APO would not be supported on these processors.

Arrow Lake-S Core Configuration and Performance

The Arrow Lake-S Desktop CPUs from Intel are set to showcase the Lion Cove P-Core and Skymont E-Core architecture. These processors boast a formidable configuration, featuring up to 8 P-cores and 16 E-cores, resulting in a powerhouse setup of 24 cores and 32 threads. This is reminiscent of the existing 14th and 13th Gen flagship CPUs.

According to a leaked slide, the Intel Arrow Lake-S Desktop CPUs offer a 5% IPC increase and a 15% increase in multi-threaded performance. There’s also mention of the new P-Cores & E-Cores which we already know are based upon the Lion Cove and Skymont architectures. The CPUs will also feature up to 50% larger L2 cache.

Arrow Lake-S 6+16 (22 Cores / 28 Threads)
Arrow Lake-S 6+8 (14 Cores / 20 Threads)

Arrow Lake-S CPU Data:

  1. The CPU will feature a configuration of 8 P-Cores and 16 E-Cores, resulting in a total of 24 cores and 32 threads.
  2. The CPUs will also feature 8 additional AI-dedicated cores with 8 threads.
  3. The CPUs will offer a 5% IPC increase and a 15% increase in multi-threaded performance.
  4. The CPUs will feature up to 50% larger L2 cache.
  5. The CPUs will also get the latest GT1 Xe-LPG iGPU but with reduced Xe-cores compared to the ones featured on Meteor Lake CPUs.
  6. The CPUs are expected to be launched in H2 2024.

Platform Details

As for the platform, Intel will be offering Arrow Lake-S Desktop CPUs on its brand new LGA 1851 socketed motherboards with the 800-series PCH which includes the Z890, H870, B860, and H810 series. The top motherboards will feature up to DDR5-6400 memory. The platform diagram reveals two more SKUs with 6+8 and 6+16 configurations.

800-Series Motherboards Configuration Overview:

  1. The platform will support DMI Gen4 1×8.
  2. It will have a total of 24 PCIe Gen4 lanes.
  3. The maximum controller configuration will be 6 x 4.
  4. It will support up to 14 root ports.
  5. There will be 8 SATA III lanes.
  6. The platform will support 3x GbE Ports.
  7. It will have 10 USB 3.2 Gen2 x1 Ports, with every two ports being usable as a single USB Gen 3.2 Gen2x2 port (maximum of 4 supported).
  8. It will also support 14 USB 2.0 Ports.
  9. The platform will feature 802.11ax R2 with TDBC (160+80), and BT6/WIFI7.
  10. There will be 1x CSME SPI and 2 x TCH SPI.

Integrated Features

For starters, the Arrow Lake-S CPUs will feature native Thunderbolt 4/USB4 support, as well as DisplayPort 2.0 (UHBR20 only) and HDMI 2.1 support. The CPUs will also get the latest GT1 Xe-LPG iGPU but with reduced Xe-cores compared to the ones featured on Meteor Lake CPUs.

Some more information I could uncover:

  1. The LGA 1851 socket is planned to be supported until 2026.
  2. The platform will only be compatible with DDR5 memory, with no support for DDR4.
  3. The launch will commence with the introduction of the 800-Series motherboards.
  4. The motherboards will natively support up to DDR5-6400 memory as per JEDEC standards.
  5. There will be an increase in PCIe Gen 5.0 lanes through both the CPU and PCH.
  6. Arrow Lake-S will be the first desktop family to be supported.
  7. Each P-Core in the Arrow Lake-S CPUs will feature a 3 MB L2 Cache.
  8. The CPUs will feature updated Alchemist-integrated GPUs.
  9. The CPUs will include an integrated LLC “Adamantine” for GPU Tile.
  10. The CPU SKUs for Arrow Lake-S will include configurations of 8+16, 8+0, and 6+8.
  11. The launch is planned for the second half of 2024.

The Intel Arrow Lake-S platform is shaping up to be a game-changer in the CPU market. With its unique core configuration, advanced features, and promising performance, it’s definitely something to look forward to in the near future.

Stay tuned for more updates as we continue to follow the development and eventual release of the Intel Arrow Lake-S Desktop CPU Platform.
