Intel Nova Lake-S leak points to powerful Xe3P graphics, 154 W boost limit, and larger cache
Fresh details about Intel’s rumored Nova Lake-S desktop APU are giving PC enthusiasts a clearer look at what the company may be preparing for its next-generation Core Ultra platform. The latest leak suggests that one of the most interesting Nova Lake-S configurations could feature a powerful integrated GPU based on Intel’s Xe3P architecture, along with notable power and cache specifications.
According to the leaked information, the Nova Lake-S desktop chip equipped with a 12-core Xe3P integrated graphics block may have an iGPU-specific PL2 limit of 40 W. PL2 refers to a short-term boost power limit, meaning this figure applies when the graphics portion is operating under heavier temporary loads rather than during sustained use.
The full chip-wide PL2 is reportedly listed at 154 W. This number includes the entire processor package, not just the integrated graphics. As with most early engineering data, these values should be treated as preliminary and may change before any final retail release.
One of the more important details involves power delivery. Earlier rumors suggested that this specific Nova Lake-S model may require a 65 W-class power-delivery segment to unlock the full performance of its integrated graphics. The new leak appears to support that claim, indicating that the 12Xe3P configuration may need two VCCGT power phases to achieve maximum GPU performance.
That detail matters because integrated graphics performance is often limited not only by architecture, but also by available power and motherboard design. If accurate, Intel may be preparing a desktop APU that pushes integrated GPU performance higher than typical mainstream desktop processors, potentially making Nova Lake-S more appealing for compact PCs, budget gaming systems, and users who want capable graphics without a dedicated GPU.
The leak also includes cache information for Intel’s upcoming Xe3-generation graphics blocks. The Xe3P 12Xe configuration expected in Nova Lake is said to include 20 MB of L2 cache. By comparison, the Xe3 12Xe graphics block planned for Intel’s Panther Lake mobile platform reportedly carries 16 MB of L2 cache.
That larger L2 cache could help improve graphics performance by reducing memory bottlenecks, especially in workloads such as gaming, media processing, and GPU-accelerated applications. Integrated GPUs rely heavily on system memory, so additional cache can play an important role in keeping performance more consistent.
The rumored Nova Lake-S chip is expected to combine a 4P+8E+4LP-E CPU layout with the 12Xe3P integrated graphics block. In simple terms, that points to a hybrid processor design with four performance cores, eight efficiency cores, and four low-power efficiency cores. This type of configuration would allow Intel to balance high-performance desktop workloads with better power efficiency during lighter tasks.
While these details are exciting, it is important to remember that Nova Lake-S has not been officially launched. The reported specifications appear to come from unreleased engineering materials, so final products could arrive with different power limits, cache sizes, graphics configurations, or CPU layouts.
Still, if the leak proves accurate, Intel’s Nova Lake-S could mark a major step forward for desktop processors with stronger built-in graphics. A 12Xe3P iGPU with 20 MB of L2 cache and a dedicated 40 W graphics boost limit would position this chip as one of Intel’s most ambitious desktop APU designs yet.
