Intel Nova Lake-S Leaks: 28-Core CPUs, AVX-512 Support, and Desktop Debut

Intel is actively developing its next-generation Nova Lake-S desktop processors, with initial engineering samples featuring 24 and 28 cores and native support for AVX-512 instructions now booting on early test platforms, according to reports from hardware publications including Profesional Review and Notebookcheck.org based on kernel logs.

Nova Lake-S Core Counts and Architecture Details

According to kernel logs cited by Notebookcheck.org, the upcoming Nova Lake-S processor family is already running on at least two designated test motherboards. German hardware reporting indicates that these initial desktop silicon samples are configured with 24 and 28 cores, pointing toward a continuation of Intel’s hybrid architecture combining performance and efficiency cores.

As reported by Profesional Review, these upcoming processors will bring back support for Advanced Vector Extensions 512, known as AVX-512. This instruction set extension handles heavy parallel workloads such as artificial intelligence, scientific simulations, and media encoding with increased efficiency. Hardware Premium further notes that leaked power distribution details point toward an integrated graphics architecture featuring 12 Xe3 graphics execution units within the Nova Lake platform.

Desktop Platform Rollout and Testing Timeline

According to Profesional Review, Nova Lake will debut first on desktop platforms rather than mobile devices, diverging from previous product launch cadences. While these early engineering samples demonstrate that hardware validation is underway on specialized test benches, Intel has not yet announced a commercial release window for retail desktop processors based on the Nova Lake architecture. The appearance of boot logs indicates that the platform has reached the stage of early silicon bring-up, allowing engineers to test power delivery, thermal responses, and instruction set execution under real-world operating conditions.
