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

Head-to-Head Benchmarks

The recorded data for these two processors is extremely one-sided, but not because of a close contest. The Intel Core Ultra 5 250KF Plus has a full suite of benchmark results, while the Intel Processor U302L has no recorded benchmark scores in the database. This means the head-to-head comparison is defined entirely by the Core Ultra 5's measured performance and the U302L's lack of any data points.

The Core Ultra 5 250KF Plus delivers a Cinebench R23 multi-core score of 42,718 and a single-core score of 6,030. In Cinebench R20, it scores 17,941 multi-core and 2,532 single-core, while the older R15 test shows 4,305 multi-core and 607 single-core. These scores place the processor in the 93rd percentile of all CPUs tracked in the database, with an average benchmark score of 66,159.

The nearest rivals in the database provide context for the 250KF Plus. The Intel Core 9 273PQE scores an average of 66,099, which is just 0.1% behind the 250KF Plus. The AMD Ryzen 9 7950X3D averages 65,914, sitting 0.4% behind. The Intel Core Ultra 5 250K Plus scores 66,855, which is 1% ahead of the 250KF Plus, and the AMD EPYC 4465P scores 66,925, also 1.1% ahead. The 250KF Plus is therefore in a tight cluster with these four rivals, all within roughly 1.5% of each other in average score.

PassMark results reinforce the 250KF Plus's standing. The multi-thread score is 50,146, with single-thread at 4,698. Integer math scores 123,030, floating point math scores 159,824, and extended instructions score 42,880. Data compression hits 553,155, data encryption scores 41,292, random string sorting reaches 67,209, and finding prime numbers scores 452. Physics testing produces a score of 3,183.

The U302L has zero benchmark entries, an average benchmark score of 0, and sits in the 50th percentile by default due to the absence of data. Database measurements can only confirm that the 250KF Plus is the measured performer in every category, while the U302L offers no recorded scores to compare. The lack of data means no direct win analysis is possible for the U302L; the 250KF Plus wins every measured category by default.

Architecture Differences

The two processors come from different architectural eras and serve different segments. The Intel Core Ultra 5 250KF Plus belongs to the Core Ultra Series 2, uses the Arrow Lake Refresh codename, and is built on TSMC's 3 nm process node. The Intel Processor U302L uses the Raptor Lake architecture with the Raptor Lake-PS codename and is fabricated on Intel's 10 nm process. The 250KF Plus has 17,800 million transistors on a 243 mm² die, while the U302L has no recorded transistor count or die size in the database.

The core configurations differ substantially. The 250KF Plus has 18 cores and 18 threads, meaning it has no hyperthreading, with a base clock of 4.20 GHz and a boost clock of 5.30 GHz. The U302L has 5 cores and 6 threads, indicating one core with hyperthreading, with a base clock of 1.20 GHz and a boost clock of 2.40 GHz. The 250KF Plus also has an unlocked multiplier, while the U302L does not.

Cache hierarchies are also different. The 250KF Plus has 192 KB of L1 cache per core, 3 MB of L2 per core, and 30 MB of shared L3 cache. The U302L has 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3 cache. The L3 advantage is significant: 30 MB versus 10 MB.

Memory support separates the two as well. The 250KF Plus supports DDR5 only with dual-channel memory and a recorded memory bandwidth of 115.2 GB/s. The U302L supports both DDR4 and DDR5 with dual-channel memory, but no memory bandwidth figure is recorded. ECC memory is supported on the 250KF Plus but not on the U302L.

PCIe capabilities differ. The 250KF Plus uses Gen 5 with 20 lanes from the CPU, while the U302L uses Gen 4 with 8 lanes from the CPU. The 250KF Plus has no integrated graphics, while the U302L includes UHD Graphics 80EU.

The production status for both is active, but the release dates differ. The U302L was released on 2024-04-07, and the 250KF Plus was released on 2026-03-10. The market segments also differ: the 250KF Plus is a desktop part, while the U302L is a mobile part.

The Verdict

The data clearly separates these two processors into different classes. The Intel Core Ultra 5 250KF Plus is a desktop processor with 18 cores, a 5.30 GHz boost clock, 30 MB of L3 cache, DDR5 support, ECC memory support, PCIe Gen 5 with 20 lanes, and a 93rd percentile ranking in the database. It has a full suite of benchmark scores confirming strong multi-core and single-core performance, with an average benchmark score of 66,159.

The Intel Processor U302L is a mobile processor with 5 cores, a 2.40 GHz boost clock, 10 MB of L3 cache, DDR4 and DDR5 support, no ECC support, PCIe Gen 4 with 8 lanes, integrated UHD Graphics 80EU, and no recorded benchmark scores. Its average benchmark score is 0, and its percentile ranking of 50 is not backed by any measured data.

For users selecting between these two based on the database, the 250KF Plus is the only one with measured performance. The U302L's lack of benchmark data means it cannot be positioned against the 250KF Plus in any performance comparison. The 250KF Plus also offers a higher core count, higher clocks, larger cache, newer process node, and broader PCIe bandwidth.

The U302L does have advantages in specific areas: it supports DDR4 memory, includes integrated graphics, has a much lower TDP of 15 watts versus 125 watts for the 250KF Plus, and targets the mobile segment. The 250KF Plus targets desktop systems and requires a discrete GPU.

The launch MSRP for the 250KF Plus is $184. The launch MSRP for the U302L is $285.

Where Each One Wins

The Intel Core Ultra 5 250KF Plus wins in every benchmark category where data exists. Its Cinebench R23 multi-core score of 42,718 and single-core score of 6,030 indicate strong performance in both heavily threaded and lightly threaded workloads. PassMark results show particular strength in data compression at 553,155 and floating point math at 159,824, which suggests good handling of scientific and financial workloads. The 93rd percentile ranking places it above the vast majority of processors in the database.

The 250KF Plus also wins on platform capabilities. PCIe Gen 5 with 20 lanes provides higher bandwidth for modern GPUs and NVMe storage. ECC memory support suits workstation or server-adjacent use cases where data integrity matters. The unlocked multiplier allows overclocking, and the higher boost clock of 5.30 GHz gives it a significant frequency advantage over the U302L's 2.40 GHz.

The Intel Processor U302L wins in efficiency and integration. Its TDP of 15 watts is dramatically lower than the 250KF Plus's 125 watts, making it suitable for mobile systems with limited cooling and battery constraints. The integrated UHD Graphics 80EU means a discrete GPU is not required, which is an advantage for compact or low-power builds. DDR4 support offers flexibility with older or cheaper memory modules, and the smaller 5-core configuration draws less power in light workloads.

The U302L also has an earlier release date of 2024-04-07, meaning it has been available in the market longer than the 250KF Plus, which was released on 2026-03-10. The U302L's mobile market segment and Socket 1700 compatibility differentiate it from the 250KF Plus's desktop Socket 1851 platform.

For users building a desktop system with performance as the priority, the 250KF Plus is the measured choice. For users building a low-power mobile system that relies on integrated graphics and can work with DDR4 memory, the U302L has the relevant specifications, though no benchmark data exists to quantify its performance.
