   • Socket: LGA1851
   • PCIe Lanes: Gen 5 x20.

2. Architecture and Process Node:

   • The 15th Gen Arrow Lake family is fabbed on Intel’s 20A process for the CPU cores and TSMC’s 3nm process for the integrated GPU (iGPU).
   • Hyper-threading has been removed, and AVX-512 instructions are not present.
   • Power limits have been reduced from 253W to 177W (PL2), with a PL4 limit of 333W.
   • The ringbus architecture is likely updated, and P-cores and E-cores are more closely “mixed.”
   • The Core i9-15900K/Core Ultra 9 2xxK is a high-end offering with impressive specifications.

3. Performance Expectations:

   • While exact performance benchmarks are yet to be released, we can anticipate excellent multi-threaded performance due to the high core count.
   • The DDR5 memory support and improved IPC (Instructions Per Clock) should contribute to overall system responsiveness.
   • The integrated Xe-LPG GPU with 64 EUs will provide decent graphics capabilities for integrated graphics.
   • The NPU (Neural Processing Unit) could enhance AI-related workloads.

4. Availability:

   • Intel has confirmed that the 15th Gen Arrow Lake processors will arrive by the end of 2024.
   • The Core i9-15900K/Core Ultra 9 2xxK will likely be part of this release.
   • Recently, these processors were spotted in the GFX CI system, which tests upcoming components for Linux, suggesting an imminent launch.

In summary, the Intel Core i9-15900K promises to be a powerhouse for enthusiasts, content creators, and gamers alike. Keep an eye out for official announcements and detailed reviews as we approach the release date! 🚀🔥
