Intel Nova Lake-S iGPU Gets 40 W Power Limit and 20 MB L2 Cache

A More Capable iGPU Takes Shape

Intel’s next desktop platform is slowly coming into focus. According to leaks from reliable Intel tipster Jaykihn, as reported by TechPowerUp, the Nova Lake-S integrated graphics solution featuring 12 Xe3P cores will operate with a Power Limit 2 setting of approximately 40 W. That number matters for everyday sustained workloads, and it slots in well below the platform’s ceiling. The 65 W figure that surfaced in earlier rumors applies to extreme scenarios, specifically PL3 and the graphics processor’s PL4 cap, not typical sustained gaming or productivity loads.

The SKU in question pairs four P-Cores, eight E-Cores, and four LPE-Cores with those 12 Xe3P GPU cores. That 4+8+4 CPU configuration is notable for another reason too: it is one of the few Nova Lake processors where the integrated graphics require two VCCGT power phases. In most desktop chips, VCCGT is a single-phase rail. The extra phase headroom explains how the platform can hit that 65 W ceiling when things get demanding, while the 40 W PL2 figure keeps everyday thermals in check.

Xe3P Brings More Than a Name Change

The jump from Xe3 to Xe3P is not purely cosmetic. The Panther Lake platform already uses a 12 Xe3-core iGPU, and that chip carries 16 MB of L2 cache. Nova Lake-S pushes that to 20 MB, a 25 percent increase, according to TechPowerUp’s reporting. More L2 cache generally benefits workloads that are sensitive to memory latency and bandwidth, which is a pretty good description of integrated graphics running anything remotely demanding.

Preliminary performance numbers are not yet available, so the real-world gaming impact of that cache bump remains an open question. Still, the Xe3P microarchitecture is described as carrying more changes than the cache alone would suggest. Whether those changes translate to a meaningful generational leap for integrated gaming performance is something that will only become clear once actual benchmarks surface.

Launch Timeline and SKU Structure

Nova Lake-S is shaping up to be a flexible platform. Depending on the SKU, Intel can configure a single compute die for up to 28 cores total or two compute dies for a 52-core CPU option. The single compute die versions are expected to arrive first. The 28-core Nova Lake-S DS SKU, which represents a new segment for Intel, is reportedly targeting Q1 2027. The enthusiast-focused K SKUs, aimed at overclocking, are said to be on track for an early Q2 launch somewhere between March and April of next year.

The 16-CPU-core, 12-GPU-core configuration discussed here fits neatly into that first wave of Nova Lake-S releases, sitting in the single compute die camp. For PC gamers who lean on integrated graphics, either because discrete GPU prices remain painful or because a compact build demands it, the specs suggest Intel is treating the iGPU as something worth engineering around rather than an afterthought.

The 40 W PL2 figure is particularly interesting context for anyone building a small form factor system. It means the integrated graphics can stretch its legs without demanding exotic cooling or a massive power delivery setup. Whether 20 MB of L2 cache and the Xe3P architecture refinements add up to playable frame rates in modern titles at reasonable settings is the question worth watching when pre-production hardware eventually makes its way into reviewers’ hands.
