Key Takeaways
1. Nova Lake Core Ultra 400 series will replace Arrow Lake-S and Arrow Lake-S Refresh processors, launching in 2026 with expected performance improvements.
2. Leaks suggest a potential 10% boost in single-core performance and a 1.6x enhancement in multi-threaded performance for Nova Lake compared to Arrow Lake-S.
3. Nova Lake may introduce a new low-power island feature, absent in previous Arrow Lake models, aiming for better energy efficiency.
4. Speculation surrounds the inclusion of a large Last Line Cache in some Nova Lake models, but details remain unclear, warranting caution.
5. Nova Lake is rumored to feature a flagship model with 16 P-cores and 32 E-cores, potentially reaching up to 52 cores, but comparisons with Arrow Lake-S may be misleading without further information.
Intel’s upcoming Nova Lake Core Ultra 400 series is set to replace the existing Arrow Lake-S and the soon-to-be-released Arrow Lake-S Refresh desktop processors. Although Nova Lake won’t be available until 2026, early leaks suggest it will offer significant performance improvements compared to Arrow Lake-S.
Performance Gains Expected
A post from Game.Keeps.Loading (@G_melo_ding) on X claims that Nova Lake might provide as much as a 10% boost in single-core performance when compared to Arrow Lake. This enhancement is likely to result in better gaming experiences and improved responsiveness for single-threaded tasks. According to the leaked information, Nova Lake is touted to achieve “Leadership Gaming Performance,” boasting a 1.1x improvement in single-thread performance and a 1.6x enhancement in multi-threaded performance.
Previous Concerns with Arrow Lake-S
Our evaluation of the Arrow Lake-S Core Ultra 9 285K revealed some performance drops during gaming, despite standalone CPU benchmarks performing well. Intel did announce several Field Updates during CES 2025 to enhance gaming capabilities, but the actual improvements vary based on the specific game. It’s to be hoped that Nova Lake-S avoids facing such issues.
New Low-Power Island on the Horizon
Additionally, there’s news about a new low-power island being developed. Notably, Nova Lake could be the first desktop CPU to include this feature. While Arrow Lake-S and Arrow Lake-HX do not have low-power islands, the Arrow Lake-H does feature two low-power E-cores in its SoC tile. However, it’s unclear if these low-power cores are based on the new Skymont design or if they are simply modified Crestmont cores from Meteor Lake.
From the information available, Nova Lake is anticipated to launch with fresh Coyote Cove P-cores and Arctic Wolf E-cores. It’s still uncertain whether they will utilize TSMC’s 2 nm process or Intel’s 18A-P technology. The Nova Lake-S series is rumored to include a flagship model, the Core Ultra 9 485K, featuring 16 P-cores, 32 E-cores, and 4 low-power island E-cores, all with a TDP of 150 W. We might also see a combination of Celestial and Druid integrated GPUs within the same SoC.
Speculations and Cautions
There is speculation that some Core Ultra 5 Nova Lake-S models will come equipped with a large Last Line Cache or bLLC, similar to AMD’s successful 3D V-cache. However, this rumor should be viewed with skepticism, as the leak lacks specific details on which CPU generation is being compared. If it is indeed against Arrow Lake-S, the single-core performance gains might not be as appealing, particularly since Nova Lake is still a year away from release.
An Arrow Lake-S Refresh expected later this year might close the performance gap with the current Arrow Lake-S models. Moreover, we still lack information on clock speeds, making any claims of performance improvements quite vague.
A 1.6x or 60% increase in multi-core capabilities sounds promising compared to Arrow Lake-S processors. However, Arrow Lake-S tops out at 24 cores in the Core Ultra 9 285K, while Nova Lake might feature a massive 52-core design, making the comparison somewhat unclear at this stage.
There’s a chance that the performance figures mentioned in the leaked slide are based on a lower-tier Core Ultra 400 model. We should gain more insights in the upcoming months, so keep an eye out for further updates.
