Where Each One Wins

The benchmark data shows a complete split: the Core Ultra 5 250K Plus is the only one of the two with recorded performance scores. The Intel Processor U301L has no entries in the database, meaning all wins across every workload category belong to the Core Ultra 5 250K Plus by default. The Core Ultra 5 250K Plus delivers 18 threads across Cinebench R15, R20, and R23, with scores of 4,640, 18,442, and 30,867 in multi-core tests, respectively. Single-core results reach 328, 2,603, and 2,261 in the same test versions.

In PassMark workloads, the Core Ultra 5 250K Plus shows strength in data compression (568,721) and floating-point math (162,692). Integer math scores 125,091, while extended instructions hit 44,565. The multi-thread PassMark score is 51,596, with a single-thread score of 4,757. The U301L has zero recorded data, so its wins cannot be quantified; the database contains no metrics for any workload on that processor.

For use-case separation, the data supports the Core Ultra 5 250K Plus for heavily threaded tasks like rendering and compression, given its 30,867 Cinebench R23 multi-core score and 568,721 data compression score. The U301L, with 5 cores and 6 threads, is a lower-thread-count part, but without benchmark scores, its relative performance in any use case cannot be stated from the recorded data. The Core Ultra 5 250K Plus also leads in memory bandwidth at 115.2 GB/s, an advantage for data-intensive workloads, whereas the U301L has no bandwidth figure in the database.

Architecture Differences

The two processors come from different design generations and foundries. The Core Ultra 5 250K Plus uses the Arrow Lake Refresh codename, built on a 3 nm process at TSMC with 17,800 million transistors and a die size of 243 mm². The Intel Processor U301L uses the Raptor Lake-PS codename, built on a 10 nm process at Intel, with no transistor count or die size recorded.

The Core Ultra 5 250K Plus features 18 cores and 18 threads, indicating no hyper-threading on any core, while the U301L has 5 cores and 6 threads, suggesting one core with two threads. The Core Ultra 5 250K Plus has larger per-core caches: 192 KB L1 and 3 MB L2 per core, versus 80 KB L1 and 1.25 MB L2 per core for the U301L. The shared L3 cache also differs: 30 MB versus 8 MB.

Memory support diverges clearly. The Core Ultra 5 250K Plus only supports DDR5, while the U301L supports both DDR4 and DDR5. The Core Ultra 5 250K Plus has ECC memory enabled, while the U301L does not support ECC. PCIe connectivity also differs: the Core Ultra 5 250K Plus provides Gen 5 with 20 CPU lanes, whereas the U301L provides Gen 4 with 8 CPU lanes.

The integrated graphics differ as well. The Core Ultra 5 250K Plus uses Arc Xe-LPG Graphics with 64 execution units. The U301L uses UHD Graphics with 64 execution units, but the architecture is not the same. The Core Ultra 5 250K Plus has an unlocked multiplier, while the U301L is locked. The Core Ultra 5 250K Plus targets the desktop segment on Intel Socket 1851; the U301L targets the mobile segment on Intel Socket 1700.

The Core Ultra 5 250K Plus also has a 93rd percentile ranking versus the U301L's 50th percentile. The average benchmark score for the Core Ultra 5 250K Plus is 66,855; the U301L has an average score of 0 due to no recorded benchmarks.

Head-to-Head Benchmarks

The head-to-head benchmark data is empty. There are no direct comparisons between the Core Ultra 5 250K Plus and the Intel Processor U301L in the database. The only benchmark scores available belong to the Core Ultra 5 250K Plus, so the analysis of its performance relative to the U301L must rely on the Core Ultra 5 250K Plus's absolute scores and its nearest rivals.

The Core Ultra 5 250K Plus achieves a Cinebench R23 multi-core score of 30,867, which indicates strong parallel throughput. Its Cinebench R20 multi-core score is 18,442, and R15 multi-core is 4,640. In single-core tests, the scores are 2,261 (R23), 2,603 (R20), and 328 (R15). PassMark multi-thread is 51,596, and single-thread is 4,757.

The nearest rivals provide context for the Core Ultra 5 250K Plus's position. The AMD EPYC 4465P has an average score of 66,925, which is 0.1% higher than the Core Ultra 5 250K Plus's 66,855. The Intel Xeon 6515P is 0.2% higher at 67,006. The Intel Core Ultra 9 275HX is 0.9% higher at 67,469. The Intel Core Ultra 5 250KF Plus is 1.1% lower at 66,159. These deltas are small, indicating the Core Ultra 5 250K Plus sits within a tight performance cluster.

For the U301L, no such comparison is possible. Its percentile rank of 50 places it below the Core Ultra 5 250K Plus's 93rd percentile, but without scores, the margin cannot be quantified. The U301L's 5 cores and 6 threads, combined with a 1.20 GHz base and 2.20 GHz boost, suggest lower peak throughput, but the data does not provide measured performance.

The largest wins for the Core Ultra 5 250K Plus are in multi-core and compression workloads. The 30,867 Cinebench R23 multi-core score and the 568,721 data compression score are the highest recorded values across its benchmark suite. Floating-point math at 162,692 and integer math at 125,091 also show strong compute capability. Data encryption scores 42,144, random string sorting 69,090, and find prime numbers 486. The physics test scores 3,494.

These numbers, while not directly comparable to the U301L due to missing data, establish the Core Ultra 5 250K Plus as a high-throughput desktop processor. The U301L's lack of recorded benchmarks means the database cannot confirm any workload advantage for it. The Core Ultra 5 250K Plus holds all measured wins by default.
