Intel Core Ultra 5 250KF Plus vs Intel Processor N250 Comparison

Head-to-Head Benchmarks

The recorded data contains a complete benchmark profile for the Intel Core Ultra 5 250KF Plus, while the Intel Processor N250 has no benchmark entries in the database. This makes a direct numerical comparison impossible for most workloads, but the available data for the Core Ultra 5 250KF Plus can be positioned against its nearest rivals to establish its performance tier.

The Core Ultra 5 250KF Plus posts an average benchmark score of 66,159, placing it in the 93rd percentile of all CPUs tracked by the database. Its closest competitor, the Intel Core 9 273PQE, scores 66,099, a negligible 0.1% difference. The AMD Ryzen 9 7950X3D trails by 0.4% with a score of 65,914. On the other side, the Intel Core Ultra 5 250K Plus leads by 1% with 66,855, and the AMD EPYC 4465P leads by 1.1% with 66,925. These margins indicate that the 250KF Plus sits in a tightly contested performance band where a few points separate the top contenders.

In Cinebench workloads, the 250KF Plus delivers a multi-core score of 42,718 in Cinebench R23 and 17,941 in Cinebench R20. The single-core results are 6,030 in R23 and 2,532 in R20. In the older Cinebench R15 test, it records 4,305 multi-core and 607 single-core. These figures show strong scaling from R20 to R23, with the multi-core score more than doubling between the two versions, consistent with the additional workload complexity in newer render tests.

PassMark results further characterize the processor. The multi-thread score is 50,146, while single-thread performance is 4,698. Integer math completes at 123,030, floating point math at 159,824, and extended instructions at 42,880. Data compression reaches 553,155, data encryption scores 41,292, and random string sorting hits 67,209. Physics simulation scores 3,183, and prime number finding scores 452. The floating point result exceeds the integer result by roughly 30%, indicating strong SIMD throughput. The encryption score is notably lower than compression, reflecting the algorithmic differences between these workloads.

Because the Intel Processor N250 has no recorded benchmarks, the database shows zero wins for each processor in direct head-to-head tests. The N250's percentile rank of 50 places it at the median of all tracked CPUs, but without actual scores, no quantitative performance statement can be made from the database.

Architecture Differences

The two processors occupy entirely different market segments and design philosophies. The Core Ultra 5 250KF Plus is a desktop part built on the Arrow Lake Refresh codename, belonging to Core Ultra Series 2 with an Ultra 5 (Arrow Lake) generation label. It uses a 3 nm process node from TSMC, packs 17,800 million transistors onto a 243 mm² die, and features 18 cores with 18 threads. Its cache hierarchy includes 192 KB L1 per core, 3 MB L2 per core, and 30 MB of shared L3 cache.

The Intel Processor N250 is a mobile processor using the Twin Lake architecture, listed under the Intel Processor (Alder Lake-N) generation. It uses Intel's 10 nm process node, has 4 cores and 4 threads, and offers 96 KB L1 per core, 2 MB shared L2, and 6 MB shared L3. No transistor count or die size is recorded for the N250.

Clock speeds diverge sharply. The 250KF Plus has a base clock of 4.20 GHz and a boost clock of 5.30 GHz. The N250 lists a base clock of 0.10 GHz and a boost of 3.80 GHz. The extremely low base clock for the N250 reflects its ultra-low-power design, with a 6 W TDP compared to the 125 W TDP of the 250KF Plus.

Memory support differs by capability and channel configuration. The 250KF Plus supports DDR5 memory on a dual-channel bus with 115.2 GB/s bandwidth. The N250 supports DDR4, DDR5, and LPDDR5, but only on a single-channel bus, delivering 38.4 GB/s. The 250KF Plus supports ECC memory; the N250 does not. The 250KF Plus uses PCIe Gen 5 with 20 CPU lanes, while the N250 uses PCIe Gen 3 with 9 CPU lanes.

The 250KF Plus has no integrated graphics, which explains the "KF" suffix. The N250 includes UHD Graphics 730. The 250KF Plus has an unlocked multiplier, the N250 does not. Sockets differ as expected: the 250KF Plus uses Intel Socket 1851, while the N250 uses Intel BGA 1264.

Release timing differs. The 250KF Plus launched on 2026-03-10 with a launch MSRP of $184. The N250 launched earlier on 2025-01-06 with no launch MSRP recorded. Both are listed as Active in production status.

Where Each One Wins

The Core Ultra 5 250KF Plus wins in every category where the database records data. Its 18 cores, 5.30 GHz boost clock, and 30 MB L3 cache place it firmly in the desktop performance tier, with an average benchmark score in the 93rd percentile. The benchmark results show particular strength in multi-threaded rendering and math workloads. Cinebench R23 multi-core at 42,718 and PassMark multi-thread at 50,146 indicate sustained throughput for CPU-bound tasks. The floating point score of 159,824 versus integer math at 123,030 suggests the architecture handles scientific and simulation workloads especially well.

The 250KF Plus also wins on platform capabilities. Dual-channel DDR5 with 115.2 GB/s bandwidth, ECC support, PCIe Gen 5 with 20 lanes, and an unlocked multiplier make it suitable for workstation and enthusiast desktop builds. The absence of integrated graphics means a discrete GPU is mandatory, but the KF designation already signals this trade-off.

The Intel Processor N250 wins on power efficiency and integration. Its 6 W TDP compared to 125 W makes it suitable for fanless or battery-powered mobile designs. The single-channel memory support for DDR4, DDR5, and LPDDR5 offers flexibility across memory types, and the integrated UHD Graphics 730 eliminates the need for a separate GPU in basic systems. Its BGA socket and mobile segment designation confirm it is not intended for upgrades or high-performance workloads.

The N250's 4 cores and 4 threads with a 3.80 GHz boost clock place it in the entry-level mobile category. Its 50th percentile rank indicates median performance among all CPUs, but the lack of benchmark data prevents precise workload characterization. The 0.10 GHz base clock suggests aggressive power management, with the processor likely idling at very low frequencies and boosting only when needed.

For use cases, the 250KF Plus suits multi-threaded desktop workloads: rendering, compilation, scientific computing, and content creation. Its 18 threads and high cache capacities align with tasks that scale across cores. The N250 suits low-power embedded or entry mobile use cases where the 6 W TDP and integrated graphics matter more than raw throughput. The database records no direct head-to-head wins because the N250 has no benchmark entries, but the specification gap between the two parts is substantial across every measurable dimension.
