Intel Nova Lake desktop CPUs show promising early single-thread performance in leaked benchmarks
Intel’s next-generation Nova Lake-S desktop processors are beginning to surface in early benchmark databases, and the first results suggest that the upcoming CPU family could bring a notable jump in single-thread performance. While these figures come from pre-production hardware and should not be treated as final, they offer an intriguing first look at what Intel may be preparing for its future desktop lineup.
Several systems running Nova Lake-S processors recently appeared in the PassMark PerformanceTest 11.1 database. The listings include 28-core engineering samples with reported boost clocks reaching up to 4.8 GHz, along with smaller eight-core variants. The most eye-catching result comes from a 28-core Nova Lake sample that scored around 5,210 points in the single-thread benchmark.
That score places the early Nova Lake chip ahead of several high-end desktop CPUs currently on the market. For comparison, Intel’s Core Ultra 9 285K is listed at around 5,059 points, AMD’s Ryzen 9 9950X3D reaches roughly 4,805 points, and Intel’s Core i9-14900KF sits near 4,635 points in the same test. Even an eight-core Nova Lake sample reportedly running at up to 4.8 GHz managed to slightly edge past the Core Ultra 9 285K in single-thread performance.
The results become even more interesting when performance is adjusted for clock speed. If the reported 4.8 GHz boost clock is accurate, the 28-core Nova Lake sample delivers approximately 1,085 PassMark points per GHz. That would represent a roughly 15% improvement over the Core Ultra 9 285K and about a 29% gain over the Ryzen 9 9950X3D based on the available figures.
However, there are important caveats. The comparison with AMD’s processor uses its official maximum boost clock, not the actual frequency it was running at during the benchmark. PassMark does not always provide full operating frequency details, so the per-clock comparison should be viewed as an estimate rather than a definitive measurement.
The multi-threaded results are less exciting at this early stage. The 28-core Nova Lake samples scored around 61,000 points, which puts them slightly ahead of the Core i9-14900KF but still behind the Core Ultra 9 285K and Ryzen 9 9950X3D. The eight-core Nova Lake entries also struggled in multi-core testing, performing well below AMD’s Ryzen 7 9850X3D despite having the same number of cores.
There are several possible explanations for the weaker multi-thread performance. These chips are likely early engineering samples, meaning they may not be running at final clock speeds or with completed firmware and software optimization. Multi-core boost behavior could also be limited at this stage, especially if power management, thermal tuning, or platform support is still unfinished.
For now, the biggest takeaway is that Nova Lake may deliver a meaningful improvement in instructions-per-clock and single-thread responsiveness. That matters for gaming, everyday desktop use, productivity software, and applications that still rely heavily on fast individual cores. If Intel can maintain strong single-core gains while improving multi-core scaling before launch, Nova Lake-S could become a major step forward for the company’s desktop processor lineup.
Intel is expected to launch Nova Lake-S desktop CPUs in the first quarter of 2027. Early reports suggest the initial lineup may include models with up to 28 cores, along with certain versions featuring significantly larger L3 caches. Those cache-heavy models could be aimed directly at high-performance gaming systems and may help Intel better compete with AMD’s 3D V-Cache processors.
As always with early benchmark leaks, these results should be treated as a preview rather than a promise. Final retail CPUs may perform differently depending on clock speeds, core configurations, cache sizes, motherboard firmware, memory support, cooling, and power limits. Still, the early single-thread numbers suggest that Intel’s Nova Lake architecture could be one of the company’s most important desktop CPU updates in years.
