Xe3P Architecture: Potential Beyond Expectations

Recent leaks suggest that Intel’s Xe3P architecture might extend its influence beyond the anticipated Crescent Island segment, indicating compatibility with several hardware aspects, including discrete GPUs. Notably, the architecture shows promise for use in the upcoming Nova Lake processor line, as indicated in prior discussions, where the Nova Lake chips are expected to feature Xe3P-based integrated GPUs (iGPUs) based on disclosures from Linux kernel patches.

The user @GawroskiT uncovered details within a hardware log file, indicating that the Xe3P will exist in two distinct variants: LPM (Low Power Media) and HPM (High Power Media).While these variants do not correspond to full GPU architectures like LPG and HPG, their presence hints at the possibility of the Xe3P powering discrete graphics, particularly through its HPM configuration.

Currently, the scope of Xe3P’s application is still somewhat unclear, with clear usage expected for data center-oriented Crescent Island GPUs. However, its implementation in the Nova Lake CPU family appears highly probable. The Nova Lake series is likely to utilize the Xe3P architecture as the primary iGPU for essential graphics functionalities, while the Xe4 (Druid) may take over display and media responsibilities. Moreover, Xe3P could serve roles within discrete graphics offerings, targeting platforms for gaming, such as the Arc gaming series, or professional applications with Arc Pro units.

Despite these insights, Intel has yet to officially confirm the existence of the LPM and HPM variants. Consequently, any assumptions surrounding the Xe3P’s role in discrete GPUs should be approached with caution. In theoretical scenarios, should Xe3P find a place in discrete graphics cards, it might be categorized under the Arc C family, also known as Celestial. However, Intel has explicitly excluded Xe3P from the Arc B family, leaving its categorization pending official confirmation.
