Leaks about Intel's upcoming Nova Lake processors reveal conflicting details on their integrated GPU architecture. Initial reports pointed to Xe3P graphics, but newer findings suggest a mix of Xe3 and Xe3P cores across different models. This could lead to varied branding under the Arc series.
The integrated graphics for Intel's Nova Lake processors, expected to follow the Panther Lake generation, have sparked debate through recent leaks. Early Linux kernel patches indicated that Nova Lake would incorporate Xe3P architecture, the same used in the Crescent Island datacenter GPU. However, a fresh analysis from leaker Coelcanth's Dream challenges this, detailing changes for Nova Lake device IDs across low-power U-series, desktop S-series, and standard H-series variants.
These IDs align with GMD 30.4.4 and 30.5.4 versions, which correspond to the Xe3-LPG architecture confirmed for Panther Lake. Notably absent is any reference to Xe3P, associated with GMD 35.11.0, implying that most Nova Lake integrated GPUs will rely on Xe3 cores. Coelcanth's Dream anticipates enhancements in display and media engines compared to those in Panther Lake and the earlier Wildcat Lake.
Contrasting this, sources cited by VideoCardz describe a hybrid approach. High-end Nova Lake-H mobile chips, positioned at the top of the stack, are said to include a full Xe3P graphics tile with 12 cores. This configuration would replace the 12 Xe3 cores in Panther Lake's premium models, potentially offering a performance edge.
Such a strategy might result in divided branding within the Nova Lake family. Standard Xe3-based integrated GPUs could carry the Arc B-series label, while Xe3P variants adopt the high-performance Arc C-series designation, depending on the specific product SKU.
The discrepancies highlight the fluid nature of pre-release information, with implications for Intel's competitiveness in integrated graphics.
