Intel Core Ultra 9 285 vs Intel Processor N250 Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark runs for the Intel Core Ultra 9 285 and the Intel Processor N250. The head-to-head benchmark array is empty, and the win counts for both processors stand at zero. This absence of paired testing data means any comparative analysis must rely on the individual benchmark scores recorded for the Core Ultra 9 285 and the architectural and specification differences between the two parts.

The Core Ultra 9 285 has a substantial set of recorded benchmark results. In Cinebench R23 multi-core, it scores 48,945 points, while its single-core result is 6,909 points. The R20 run shows 20,556 multi-core and 2,901 single-core. In the older R15 test, the multi-core score is 4,933 and single-core is 696. PassMark results are equally extensive: multithreaded score of 56,602, single-thread score of 4,881, integer math at 164,869, floating point math at 194,988, data compression at 602,121, data encryption at 46,949, extended instructions at 45,357, prime number finding at 459, random string sorting at 73,651, and physics at 3,598.

The Intel Processor N250 has no benchmark scores recorded in the database. Its average benchmark score is listed as 0, and its percentile versus all CPUs is 50. The Core Ultra 9 285, by comparison, sits at the 95th percentile across all CPUs in the database. The Core Ultra 9 285 also carries an average benchmark score of 75,488, placing it in close company with several AMD EPYC and Ryzen parts. The nearest rivals show a tightly grouped field: the AMD EPYC 8224P averages 75,582 (0.1% higher), the AMD EPYC 4545P averages 75,373 (0.2% lower), the AMD Ryzen 7 PRO 9755X3D averages 75,716 (0.3% higher), and the AMD Ryzen 7 PRO 9755 averages 75,738 (0.3% higher). These delta percentages are small, meaning the Core Ultra 9 285 effectively trades places with these server and workstation processors within a fraction of a percent.

Because the N250 has no recorded benchmark data, there are no wins to assign in either direction. The Core Ultra 9 285’s scores stand alone, and the N250’s performance profile must be inferred from its specifications rather than from measured results.

The Verdict

The data indicates a clear separation in intended use and measured capability. The Core Ultra 9 285 is a desktop processor with 24 cores and 24 threads, a base clock of 2.50 GHz, and a boost clock of 5.60 GHz. It consumes 65 watts TDP and uses the Intel Socket 1851. Its benchmark scores place it at the 95th percentile of all CPUs in the database, with an average score of 75,488. The nearest rivals are all AMD EPYC or Ryzen PRO parts, and the deltas are under 0.3% in either direction, showing that the Core Ultra 9 285 performs in the same class as those high-end server and workstation chips.

The Intel Processor N250 is a mobile part with 4 cores and 4 threads, a base clock of 0.10 GHz, and a boost clock of 3.80 GHz. Its TDP is 6 watts, and it uses the Intel BGA 1264 socket. It has no recorded benchmark scores and no nearest rivals in the database. Its percentile is 50, which is a neutral midpoint, but this number is not backed by any measured scores. The N250’s role is clearly low-power mobile computing, while the Core Ultra 9 285 targets high-performance desktop workloads.

From the recorded data alone, the Core Ultra 9 285 is the only one of the two with measurable performance evidence. Its multi-core Cinebench R23 score of 48,945 and PassMark multithread score of 56,602 indicate a processor designed for heavy parallel workloads. The N250, with its 4 cores, 6 watts, and single-channel memory, is not in the same performance class. The verdict from the data is straightforward: the Core Ultra 9 285 is for users who need high throughput, and the N250 is for systems where power consumption is the overriding constraint. No benchmark results exist for the N250 to suggest otherwise.

Architecture Differences

The two processors come from different architectural families and are built on different process nodes. The Core Ultra 9 285 uses the Arrow Lake architecture, specifically Arrow Lake-S, and belongs to the Core Ultra Series 2. It is fabricated on a 3 nm process at TSMC, with 17,800 million transistors on a 243 mm² die. The N250 uses the Twin Lake architecture, which is part of the Intel Processor family and traces its generation to Alder Lake-N. It is built on a 10 nm process at Intel, with no transistor count or die size recorded in the database.

Cache structures differ markedly. The Core Ultra 9 285 has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 36 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 Core Ultra 9 285’s per-core L2 allocation is significantly larger, and its total L3 is six times that of the N250.

Memory architecture also separates the two. The Core Ultra 9 285 supports DDR5 memory over a dual-channel bus, with a recorded memory bandwidth of 102.4 GB/s. It also supports ECC memory. The N250 supports DDR4, DDR5, and LPDDR5 over a single-channel bus, with a memory bandwidth of 38.4 GB/s. It does not support ECC memory. The Core Ultra 9 285 offers nearly three times the memory bandwidth of the N250.

PCIe connectivity reflects their market positions. The Core Ultra 9 285 provides PCIe Gen 5 with 20 lanes from the CPU. The N250 provides PCIe Gen 3 with 9 lanes from the CPU. Integrated graphics differ as well: the Core Ultra 9 285 uses Arc Xe-LPG Graphics with 64 execution units, while the N250 uses UHD Graphics 730.

The production status for both is active, but their release dates are different. The Core Ultra 9 285 was released on 2024-12-31, and the N250 was released on 2025-01-06. The Core Ultra 9 285 has a launch MSRP of $579, while the N250 has no recorded launch MSRP. Neither processor has an unlocked multiplier.

Where Each One Wins

The recorded data shows the Core Ultra 9 285 wins in every measurable performance category, simply because it is the only one with benchmark scores. Its Cinebench R23 multi-core score of 48,945 and single-core score of 6,909 indicate strong performance in both heavily threaded and lightly threaded workloads. The PassMark results reinforce this: integer math at 164,869, floating point math at 194,988, and data compression at 602,121. The 95th percentile ranking against all CPUs in the database places it among the top performers, and its nearest rivals are all AMD EPYC or Ryzen PRO parts within 0.3% of its average score. For desktop users running demanding applications, the Core Ultra 9 285 delivers recorded throughput that the N250 cannot match.

The N250 wins in power efficiency, based on specifications. Its 6 watt TDP is less than one-tenth of the Core Ultra 9 285’s 65 watts. Its 0.10 GHz base clock suggests an extremely low-power idle state, and its 3.80 GHz boost clock provides modest headroom when needed. The single-channel memory bus and 38.4 GB/s bandwidth are modest, but they align with a low-power mobile design that prioritizes battery life over throughput. The N250 also supports LPDDR5 memory, which is common in mobile systems, and its PCIe Gen 3 with 9 lanes is sufficient for lightweight peripherals. The N250’s integrated UHD Graphics 730 provides display output without a discrete GPU, and the mobile BGA 1264 socket indicates a soldered, compact form factor.

The use-case split is clear from the data. The Core Ultra 9 285 is for desktop systems where multi-core performance, high memory bandwidth, and PCIe Gen 5 connectivity are required. The N250 is for mobile devices where a 6 watt TDP and single-channel memory are acceptable trade-offs for extreme power savings. The absence of benchmark scores for the N250 means its actual performance is unverified in the database, but its specifications place it in a fundamentally different segment. Each processor wins in its own domain: the Core Ultra 9 285 in raw measured performance, and the N250 in power efficiency and mobile integration.
