Intel’s 15th Gen CPUs to Harness 20A Process, Lunar Lake on 18A: TSMC’s 3nm for iGPUs

Intel has announced its plans for the future of its CPUs, with the upcoming 15th Gen Arrow Lake and Lunar Lake processors set to make significant advancements. These new CPUs will harness TSMC’s 3nm-class process nodes, marking a continuation of Intel’s outsourcing strategy.

The 15th Gen Arrow Lake lineup will feature Intel’s 20A node for the CPU tile, while the iGPU tile will utilize TSMC’s 3nm (N3) node. This upgrade from the previous Meteor Lake will bring a more advanced CPU tile, with an increase from 4A to 20A. The iGPU tile, however, will remain unchanged.

Lunar Lake, on the other hand, will be limited to the notebook segment and will be produced in limited quantities for high-end and enthusiast ultrabooks/convertibles. It will feature a CPU tile fabricated on Intel’s 18A node and an iGPU tile outsourced to TSMC’s N3B node (3nm+).

Intel’s Foundry division is also making strides to become a separate entity, aiming to serve rivals such as AMD, ARM, and nVidia. CEO Pat Gelsinger revealed that there will be a clear separateion between Intel products and Intel Foundry, with separate legal entities and budgets for each division.

The 15th Gen Arrow Lake processors are expected to be the most significant upgrade since Alder Lake. They will adopt a disaggregated (chiplet) architecture, featuring a 2nm-class 20A CPU die. The P-Cores will be upgraded to Lion Cove, while the E-Cores will see an improvement to Skymont. The iGPU tile will remain the same as Meteor Lake, utilizing the Xe-LPG architecture on TSMC’s 3nm node. These processors will offer up to 24 cores (8P + 16E) without hyperthreading, signaling Intel’s transition from SMT to Rentable Units.

Leaked Intel documents suggest that the 15th Gen processors will bring a 5% uplift in single-threaded performance and a 15% boost in multi-threaded performance. Additionally, the P-core L2 cache is expected to increase by 50% to 3MB.

Lunar Lake, on the other hand, will be a successor to Lakefield and will be fabricated on Intel’s 18A node for the CPU and TSMC’s N3B node for the iGPU. These chips will feature up to 10 cores (4P + 4E + 2LP) and will be similar to Arrow Lake but produced on superior nodes with a lower TDP of 7-15W. They are scheduled to launch during the holiday season following Arrow Lake’s release.

Overall, Intel’s 15th Gen CPUs, including Arrow Lake and Lunar Lake, promise significant advancements in performance and architecture. With the utilization of TSMC’s advanced process nodes, Intel aims to stay competitive in the ever-evolving CPU market. As we look towards the future, it will be interesting to see how these new processors fare against their competitors and what further innovations Intel has in store.
