Newly published die shots of Intel´s ´Arrow Lake´ desktop processors confirm a complex chiplet architecture built atop a base die using Intel´s 22 nm FinFET process. Shared by the YouTube channel HighYield, the annotated images display a distinctive four-tile configuration: the compute tile, manufactured on TSMC´s advanced N3B process and sized at 117.24 mm²; an SoC tile to its right, also from TSMC but on the N6 node, measuring 86.65 mm²; a GPU tile next to the SoC tile, featuring four Xe graphics cores and an Arc Alchemist render slice; and a 24.48 mm² I/O tile, also on TSMC N6, occupying the bottom left of the package. This new design marks a significant departure from previous architectures by integrating these elements atop a foundational die through Intel´s Foveros Omni stacking technology.
Arrow Lake also introduces a reworked hybrid core strategy, shifting away from physically separate clusters of high-performance P-cores and efficient E-cores. Instead, four of the eight P-cores are positioned along the die´s outer edge, while the other four are at the center. The four E-core clusters are interleaved between the P-cores, each accessing 3 MB of dedicated L2 cache. All cores are interconnected via a unified 36 MB L3 cache ring bus, and for the first time, E-cores benefit from access to the sizable L3 cache pool, potentially enhancing background processing and heat distribution across the die.
Each tile in the Arrow Lake architecture serves a dedicated function: the I/O tile incorporates Thunderbolt 4 controllers, PCIe buffers, and PHYs; the SoC tile embeds display engines, media accelerators, and DDR5 memory controllers. Intel´s decision to favor TSMC´s foundry services over its in-house 20A node for this processor represents a pivotal change in manufacturing strategy, making Arrow Lake the company´s first desktop CPU series to be almost entirely produced by external partners. On the software front, Intel is rolling out IPO profiles within select prebuilt systems—allowing seamless optimization of CPU and memory performance under warranty-safe conditions. The 200S Boost, available via BIOS updates, provides modest overclocking gains with ultra-fast DDR5, but the IPO profiles are proving to deliver broader, more consistent performance improvements with mainstream memory configurations.
