Intel "Nova Lake-S" iGPU with 12 Xe3P Cores to Feature 40 W PL2 and 20 MB of L2 Cache
According to the reliable Intel leaker Jaykihn, Intel's upcoming "Nova Lake-S," featuring 12 Xe3P cores, currently has a Power Limit 2 (PL2) setting of about 40 W. This builds on the previous rumor that this integrated graphics solution will arrive with two VCCGT phases for up to 65 W of power. This SKU includes four P-Cores, eight E-Cores, and four LPE-Cores, along with 12 Xe3P GPU cores. This 4+8+4 CPU core and 12 GPU core configuration is one of the few processors where integrated graphics require two VCCGT phases. In regular SKUs, VCCGT is a single-phase power rail for the integrated graphics inside the processor.
However, we now know that the PL2 setting will only use 40 W, as the 65 W threshold is set for extreme scenarios like PL3, and the graphics processor's PL4 is capped at that 65 W figure. The Xe3P features more microarchitectural changes compared to the Xe3 found in "Panther Lake." If readers recall, a 12 Xe3-core iGPU found in "Panther Lake" has 16 MB of L2 cache, while the Xe3P iGPU dedicated to "Nova Lake" will have a 20 MB L2 cache configuration, a 25% increase. More L2 cache means that some workloads will naturally benefit, but we still don't know preliminary performance. The Xe3P microarchitecture is expected to carry more changes, especially since it has a larger L2 cache.Depending on the SKU, Intel can include a single compute die for up to 28 cores total or two compute dies for a 52-core CPU SKU. It seems that the single compute die version will arrive first, with the dual compute die variants following. The 28-core "Nova Lake-S" DS version, a new SKU segment, is expected to launch in Q1 of 2027. For the regular overclocking-focused "K" SKUs, Intel reportedly plans an early Q2 launch between March and April. Since this is a single compute die SKU with 16 CPU cores and 12 GPU cores, we can expect to see it possibly within the first wave of the "Nova Lake" releases.

Don't hear me wrong, AMD has been lax on iGPUs for a while now. I'm still waiting on them to rise to the mobile iGPU challenge that Intel is throwing down. At this point, I think they just assume their CPUs will get paired with an NVIDIA dGPU in whatever form factor goes out, as AMD has largely given up on mobile dGPUs as well. The best they have there are RDNA3 chips that launched almost 3 years ago, to little fanfare.
Btw @john_ it seems more like an upper midrange CPU, still very interesting.
OTOH Intel is not generous with P-cores, but reaching 154w PL2 (or even 114w) with only 4 P-cores seems very inefficient.
It's a few(?) months of waiting.
