Intel 15th Gen Core i7-15700K, Core i9-15900K Specs and Release Date [Update]

Intel's 15th Gen Arrow Lake family will be fabbed on the 20A process (CPU) and TSMC's 3nm (iGPU) node

Intel’s 15th Gen Arrow Lake processors will offer a sizable upgrade over existing 14th Gen parts. Combining upgraded core architectures with cutting-edge process nodes, we can expect a highly competitive lineup by the end of 2024. Intel has repeatedly confirmed that the 15th Gen Arrow Lake processors will arrive by the year’s end, leveraging its cutting-edge 20A process node and Foveros 3D packaging.

Update: The 15th Gen Arrow Lake processors will likely be called the Core Ultra 2 series processors. However, until there’s an official announcement from Intel for better discoverability, we’ll continue to use the existing title.

Intel’s 15th Gen Arrow Lake family will be fabbed on the 20A process (CPU) and TSMC’s 3nm (iGPU) node. Hyper-threading has been removed, and AVX-512 remains MIA. The power limits have been reduced from 253W to 177W (PL2), while the PL4 limit stands at 333W. The ringbus will likely be updated, and as per tipsters, the P-cores and E-cores will be more closely “mixed.”

Intel Core i5-15600K (Core Ultra 5 2xxK)

According to a recent report from Bilibili, only the 6P + 8E core CPU tile (used on the Core i5s) will be fabbed on the prestigious Intel 20A node. The higher-end 8P + 16E CPU die will allegedly be manufactured on an advanced 3nm-class TSMC node. The tipster alleges that all mobile Arrow Lake CPU tiles will also be fabbed on the advanced TSMC process node. He confirms that the NPU will be retained while LPE cores on the SoC die will be disabled. The Arrow Lake desktop processors will leverage the lower-end iGPU tile from Meteor Lake (with 4 Xe Cores).
