A Linux 7.3 kernel driver patch adds device IDs 0xD74A and 0xD748 while dropping 0xD744, raising the count of recognized Nova Lake-S Xe3 desktop GPUs to seven. The expansion hints that Intel may be developing up to seven SKUs for the Core Ultra 400-series, though not all device IDs necessarily translate to retail products. The same Xe3 graphics architecture powers Panther Lake's Arc B300-series iGPUs and the Arc G3 Extreme SoC already shipping in gaming handhelds.

Intel also updated its media engine: the Protected Xe Path no longer requires HuC firmware in kernel space, shifting that load to user space instead. Whether the flagship Arc B390 iGPU will appear in desktop form remains unconfirmed, but Nova Lake-S is designed around AI-accelerated workloads that benefit from additional GPU cores alongside the integrated NPU.

Separately, Intel is readying two gaming-oriented SKUs packing 22 cores and a massive 108 MB bLLC cache. That cache size dwarfs current desktop offerings and signals a direct play for enthusiast workloads where latency-sensitive gaming performance matters.

Seven device IDs in Linux doesn't guarantee seven retail parts, but it reveals a broader segmentation strategy than prior generations. The cache-heavy gaming variants and AI-focused core counts suggest Intel is finally treating integrated desktop graphics as a serious performance tier rather than a baseline feature.
