Intel NPU6 for Nova Lake will bring significant speed boost
Hardware leaker Jaykihn has posted a new update on Intel’s Nova Lake-S desktop CPUs. The tweet claims that Nova Lake-S will pair Xe3-LPG integrated graphics (two cores) with a new sixth generation NPU block, NPU6 . This lines up with our own report from last week on the graphics side and adds the first clear NPU detail for the desktop series.
Our information suggests that Nova Lake-S reusing the same Xe3-LPG architecture planned for Panther Lake and Wildcat Lake rather than the Xe3P core from the Crescent Island data center GPU. The newer architecture will be used, but for other Nova Lake chips (premium mobile). Jaykihn’s post directly tags Nova Lake-S with Xe3-LPG, specifically the 2x Xe3 variant. Jaykihn says that this is a downgrade given that current-gen destkop series feature 4 cores (but keep in mind it should be much faster than Xe-LPG with XMX as featured in Arrow Lake).
NVL-S ships with NPU6 at 74 TOPS, a three-generation uplift from the 13 TOPS of ARL-S.
The iGPU is comprised of 2 Xe3-LPG cores, a regression in core count from the 4 in ARL-S.

The NPU side is where Nova Lake-S makes the biggest step. Arrow Lake and Arrow Lake Refresh both rely on the NPU3 block, which delivers around 13 INT8 TOPS on desktop. Jaykihn states that Nova Lake-S moves to NPU6, skipping NPU5 entirely. According to this leakNPU6 in roughly the 74 TOPS range, so our updated table lists Nova Lake with a 74 TOPS target, which works out to about 5.6x higher raw NPU throughput than Arrow Lake-S.
Intel NPU generations
- NPU3 – Meteor Lake – 11.5 TOPS Mobile
- NPU3 – Arrow Lake – 13 TOPS Mobile & Desktop
- NPU4 – Lunar Lake – 48 TOPS Mobile
- NPU5 – Panther Lake – 50 TOPS 🆕 Mobile
- ➡️NPU6 – Nova Lake – 74 TOPS 🆕 Mobile & Desktop ⬅️
The just-announced Panther Lake chip is to feature NPU5 with up to 50 TOPS, a small upgrade over Lunar Lake’s NPU4, however Intel mentions that the 5th generation was focusing on improvement in TOPS/area and optimizations for newer workloads.

Intel has been ramping its client NPU designs quickly. Meteor Lake introduced NPU3 with up to 11.5 TOPS on mobile, while Arrow Lake reused that block at higher clocks for 13 TOPS on desktop. If Nova Lake-S now adopts NPU6 alongside Xe3-LPG graphics as claimed, Intel’s next desktop platform should move to the same NPU generation as its mobile stack instead of trailing by one design cycle.
