Intel Core Ultra 7 366H vs Intel Processor N250 Comparison

Head-to-Head Benchmarks

The benchmark database contains no direct head-to-head comparison results between the Intel Core Ultra 7 366H and the Intel Processor N250. The Core Ultra 7 366H has a full suite of recorded measurements, while the N250 has no benchmark entries at all. This asymmetry in available data makes direct score-for-score comparisons impossible. However, the recorded data for the Core Ultra 7 366H can be positioned against its nearest rivals, and the N250 can be assessed through its percentile ranking.

The Core Ultra 7 366H delivers a Cinebench R23 multi-core score of 28477 and a single-core score of 4020. In Cinebench R20, it records 11960 multi-core and 1688 single-core. Cinebench R15 shows 2870 multi-core and 405 single-core. PassMark results include a multi-thread score of 33429, single-thread of 4043, integer math at 83695, floating point math at 103615, data compression at 327455, data encryption at 25845, extended instructions at 26901, find prime numbers at 326, physics at 2880, and random string sorting at 39814.

Its average benchmark score across all recorded tests is 41263, which places it in the 87th percentile of all CPUs in the database. The nearest rivals are tightly clustered. The Intel Core Ultra 7 356H averages 41215, a delta of 0.1 percent. The AMD Ryzen AI 5 PRO 440 averages 41208, also a delta of 0.1 percent. The AMD Ryzen 9 5900X averages 41376, putting the 366H behind by 0.3 percent. The Intel Core Ultra X7 358H averages 40967, meaning the 366H leads by 0.7 percent. These deltas are small, indicating that the 366H sits in a highly competitive performance band where no single rival holds a decisive edge.

The Intel Processor N250 has no recorded benchmark scores in the database. Its percentile rank is 50, which places it exactly at the midpoint of all CPUs. Without individual test scores, the database cannot quantify its performance in any specific workload. The absence of data means the N250 cannot be compared numerically to the Core Ultra 7 366H in any of the standard tests such as Cinebench or PassMark.

Architecture Differences

The Core Ultra 7 366H uses the Panther Lake architecture, codenamed Panther Lake, and belongs to the Ultra 7 (Panther Lake-H) generation within the Core Ultra Series 3. It is built on Intel's 3 nm process node. The N250 uses the Twin Lake architecture, codenamed Twin Lake, and is listed as Intel Processor (Alder Lake-N) generation. It is built on Intel's 10 nm process node. Both chips are manufactured by Intel, but the process difference is substantial: 3 nm versus 10 nm.

Core counts differ sharply. The 366H has 16 cores and 16 threads. The N250 has 4 cores and 4 threads. Neither chip supports simultaneous multithreading, as thread counts equal core counts for both. Cache hierarchies diverge significantly. The 366H has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The N250 has 96 KB of L1 cache per core, 2 MB of shared L2 cache, and 6 MB of shared L3 cache. The 366H thus carries roughly double the L1 per core, more L2 per core, and three times the total L3.

Clock speeds follow the same pattern. The 366H has a base clock of 2.00 GHz and a boost clock of 4.80 GHz. The N250 has a base clock of 0.10 GHz and a boost clock of 3.80 GHz. The 366H's boost clock is 1.00 GHz higher, and its base clock is far higher in absolute terms.

Memory support differs. The 366H supports DDR5 and LPDDR5X over a dual-channel memory bus, with a recorded memory bandwidth of 115.2 GB/s. The N250 supports DDR4, DDR5, and LPDDR5 over a single-channel memory bus, with a recorded memory bandwidth of 38.4 GB/s. The bandwidth gap is exactly threefold in favor of the 366H. Neither chip supports ECC memory.

PCIe connectivity differs by generation and lane count. The 366H uses PCIe Gen 5 with 12 lanes (CPU only). The N250 uses PCIe Gen 3 with 9 lanes (CPU only). Integrated graphics also differ: the 366H includes Intel Xe3 Graphics, while the N250 includes UHD Graphics 730.

Thermal design power is heavily skewed. The 366H has a TDP of 25 watts. The N250 has a TDP of 6 watts. This is a ratio of roughly 4.2 to 1, indicating very different power envelopes and thermal design targets.

Sockets differ. The 366H uses Intel BGA 2540. The N250 uses Intel BGA 1264. Release dates also differ: the 366H was released on 2026-01-04, while the N250 was released on 2025-01-06. Both are marked as active production and both are mobile market segment parts. Neither chip has an unlocked multiplier.

The Verdict

The data indicates a clear performance hierarchy. The Core Ultra 7 366H occupies the 87th percentile of all CPUs, with a substantial average benchmark score of 41263. The N250 sits at the 50th percentile with no recorded average score. Every architectural metric favors the 366H: more cores, more threads, larger caches, higher clocks, faster memory bandwidth, newer PCIe standard, newer process node, and a larger power envelope.

The N250's 6 watt TDP and 4-core configuration position it as a low-power part. Its 3.80 GHz boost clock and 6 MB of L3 cache are modest figures. The 366H, with 25 watts and 16 cores, is positioned for substantially heavier workloads. The 366H's performance class, as indicated by its nearest rivals (all within 0.7 percent of its average score), shows it competes with high-end desktop and mobile processors. The AMD Ryzen 9 5900X being only 0.3 percent ahead confirms this tier.

For users whose workloads demand multi-core throughput, the 366H is the only choice supported by the recorded data. Its Cinebench R23 multi-core score of 28477 and PassMark multi-thread score of 33429 indicate strong parallel performance. The N250 has no such measurements, so no claim of comparable throughput can be made.

For power-constrained or thermally limited systems, the N250's 6 watt TDP and 50th percentile rank indicate a much lighter processing footprint. The database does not record any performance scores for the N250, so its actual speed in specific tasks cannot be stated. The only verifiable facts are its architectural parameters and its median percentile standing.

The 366H's 4.80 GHz boost clock, 18 MB L3 cache, and dual-channel 115.2 GB/s memory bandwidth give it clear advantages in memory-intensive and latency-sensitive workloads. The N250's single-channel 38.4 GB/s bandwidth and 6 MB L3 cache are limiting factors for such tasks. The 366H also leads in PCIe generation, with Gen 5 versus Gen 3, which matters for external device throughput.
