Intel Core Ultra 5 250K Plus vs Intel Processor U302L Comparison

Head-to-Head Benchmarks

The Core Ultra 5 250K Plus has a complete set of recorded benchmark scores, while the Intel Processor U302L has none in the database. This makes direct head-to-head comparisons impossible on a test-by-test basis. However, the aggregate data provides a clear separation. The Core Ultra 5 250K Plus achieves an average benchmark score of 66,855, placing it in the 93rd percentile of all CPUs tracked. The U302L sits at the 50th percentile with an average benchmark score of zero, reflecting the absence of recorded performance data.

The nearest rivals for the Core Ultra 5 250K Plus give context to its standing. It trails the AMD EPYC 4465P by 0.1%, with that rival averaging 66,925. The Intel Xeon 6515P is 0.2% ahead at 67,006. The Intel Core Ultra 9 275HX leads by 0.9% with 67,469. The Core Ultra 5 250KF Plus, a close sibling, scores 66,159, putting the 250K Plus 1.1% ahead. These deltas are all within roughly one percent, indicating that the 250K Plus performs in a tightly packed band near the top of the database.

Architecture Differences

The two processors come from different architectural lineages. The Core Ultra 5 250K Plus uses the Arrow Lake Refresh codename and belongs to the Core Ultra Series 2 generation, identified as Ultra 5 (Arrow Lake). Its process node is 3 nm, fabricated by TSMC. The Intel Processor U302L is based on Raptor Lake architecture, with the codename Raptor Lake-PS, and uses a 10 nm process node from Intel's own foundry. These are fundamentally different designs, separated by two process generations and distinct manufacturing sources.

The Core Ultra 5 250K Plus contains 17,800 million transistors on a die size of 243 mm². The U302L has no recorded transistor count or die size in the database. Cache hierarchies differ sharply. The 250K Plus provides 192 KB of L1 cache per core, 3 MB of L2 per core, and 30 MB of shared L3 cache. The U302L offers 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3. The 250K Plus has three times the L3 capacity and larger per-core caches at every level.

Memory support also diverges. The 250K Plus supports DDR5 memory only, with dual-channel configuration and a recorded memory bandwidth of 115.2 GB/s. It supports ECC memory. The U302L supports both DDR4 and DDR5, also dual-channel, but has no recorded memory bandwidth figure and does not support ECC. The PCIe interface differs as well: the 250K Plus uses Gen 5 with 20 lanes (CPU only), while the U302L uses Gen 4 with 8 lanes (CPU only). Integrated graphics are present on both, with the 250K Plus using Arc Xe-LPG Graphics with 64 execution units, and the U302L using UHD Graphics with 80 execution units.

The 250K Plus has an unlocked multiplier, indicating overclocking capability. The U302L does not. The 250K Plus uses a 3 nm TSMC process, while the U302L uses Intel's 10 nm process. These architectural differences account for the substantial performance gap implied by the benchmark data, even though the U302L lacks direct scores.

The Verdict

The recorded data points to a decisive performance advantage for the Intel Core Ultra 5 250K Plus. Its average benchmark score of 66,855 places it in the 93rd percentile of all CPUs, with a complete set of Cinebench and PassMark results confirming strong multi-threaded and single-threaded performance. The Intel Processor U302L has no benchmark scores, an average score of zero, and a 50th percentile rank. The 250K Plus also dominates on specification: 18 cores versus 5, a 5.30 GHz boost clock versus 2.40 GHz, 30 MB of L3 versus 10 MB, and a 3 nm TSMC process versus Intel's 10 nm node.

The U302L is a mobile part with a 15-watt TDP, designed for low power consumption rather than peak throughput. It supports both DDR4 and DDR5 memory, which offers flexibility for system builders, and it includes UHD Graphics with 80 execution units. The 250K Plus is a desktop part with a 125-watt TDP, capable of higher sustained performance but requiring more power and a different platform.

For users selecting a desktop processor with high compute throughput, the data clearly favors the Core Ultra 5 250K Plus. Its benchmark results place it within one percent of top-tier workstation and server parts like the AMD EPYC 4465P and Intel Xeon 6515P, while using a mainstream desktop socket. The unlocked multiplier and Gen 5 PCIe support add to its appeal for high-performance builds.

For mobile applications where power efficiency is the priority, the Intel Processor U302L fits a different role. Its 15-watt TDP and dual memory support make it suitable for low-power systems, but the absence of benchmark data means no performance claims can be made from the database. The 50th percentile rank indicates a mid-tier position, but without recorded scores, any quantitative comparison is impossible.

The verdict from the data is straightforward: the Core Ultra 5 250K Plus is the higher-performing processor, backed by complete measurements across multiple benchmark suites. The U302L remains an unquantified part in the database, suitable only for qualitative assessment based on its low TDP and mobile orientation. Buyers seeking maximum performance from the recorded data should choose the 250K Plus. Buyers needing a low-power mobile processor will find the U302L's specifications, but no benchmark evidence to validate its performance level.
