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.

Intel seems to be taking risks that AMD has likely rejected in the past. So, let's see a GPU-powerful APU that isn't also a chip with way too many cores. For 15 years, we've been waiting for a powerful APU paired with a mid-range CPU so someone doesn't have to shell out an insane amount of money to get it. What do I mean 15—for 150 years we've been asking AMD to put its most powerful integrated graphics on a low-cost CPU, but noooooooo. You want a powerful integrated GPU? You'll only find it on the most expensive CPU. You idiots, if I were dropping $300+ on a CPU, do you really think I'd be sticking with integrated graphics?

This is pretty cool, 65w eh I wonder how it would compare to say a rtx3050 6gb since that uses about 75w all entirely from the pci-e

I'd blame OEMs for a lot of that. That's where most of the sales come from, and I doubt any of them were asking for a CPU that might justify a customer to go cheap. They want to upsell. Now that the market is on its head, there is certainly an opportunity for such a thing, but it remains to be seen if it will actually be affordable. The upsized GPU might be reason enough for OEMs to justify upcharging for it. Even then, there have been times where AMD did try to offer something decent, and OEMs would ship it out with slow single-channel memory.

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.

This is likely the same silicon as Nova Lake H for laptops or handhelds. Intel is simply not disabling functional units for the desktop/NUC version.

Combined with a dGPU will the CPU be able to use the total PL2 of 154w as usual?

Btw @john_ it seems more like an upper midrange CPU, still very interesting.

It might be a 16 core model, but only 4 cores are P cores. Also 4 of the other cores are LPE-Cores. Now in a line up with a maximum number of cores, let's say 24, this could be a mid range model. But in a line up that latter will have models with 52 cores, this should be categorized as a low to mid range model. If it is build entirely at Intel's fabs, I could see it coming at a price of under $200. But because we are talking about multi billion dollar companies trying to make as much profit as possible, Intel could easily disappoint me with a $300 price tag.

I'm ranking the CPU solely based on PL2. Although not directly comparable, it is very close to e.g. 250K, but on (in theory) a more efficient node, so...
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.

can anyone hazard a guess as to what we'll see FLOP wise for FP32 and FP16? seeing as intel seems to be on a hot streak with integrated graphics, we can expect a fair outing...
