Intel Core Ultra X9 378H vs Intel Processor U302L Comparison

The Verdict

The database comparison between the Intel Core Ultra X9 378H and the Intel Processor U302L presents a stark contrast in performance tiers. The Core Ultra X9 378H sits at the 89th percentile of all CPUs, while the U302L sits at the 50th percentile. The X9 378H carries an average benchmark score of 47,468, whereas the U302L has no recorded average benchmark score in the database, leaving it without a measurable performance baseline. The X9 378H's nearest rivals include the AMD Ryzen 9 PRO 5945 (average score 47,527, a 0.1% difference), the Intel Core i7-13700KF (average score 47,330, a 0.3% difference), the Intel Core Ultra 7 265T (average score 47,697, a 0.5% difference), and the Intel Core i9-12900F (average score 47,176, a 0.6% difference). These deltas show the X9 378H is effectively neck-and-neck with a group of high-end desktop and mobile processors, differing by less than a single percentage point in each case. The U302L, with no benchmark entries and no rival list, cannot be positioned against any comparable processor in the database.

The correct choice depends entirely on workload expectations. The X9 378H is the only option with recorded performance data, and it demonstrates strong multi-threaded and single-threaded capabilities across Cinebench and Passmark tests. The U302L offers no measured scores, so any performance claim about it would be unsupported by the database. For users who require proven computational throughput, the X9 378H is the sole candidate with evidence. For users who prioritize lower thermal design power, the U302L specifies 15 watts compared to the X9 378H's 25 watts, which may suit constrained mobile chassis, but the lack of benchmark data means its actual performance remains unknown.

Architecture Differences

The two processors come from different Intel generations and manufacturing nodes. The Core Ultra X9 378H uses the Panther Lake codename, belongs to the Ultra X9 (Panther Lake-H) generation, and is built on a 3 nm process by Intel. The Processor U302L uses the Raptor Lake codename, belongs to the Intel Processor (Raptor Lake) generation, and is built on a 10 nm process. The core counts differ substantially: the X9 378H has 16 cores and 16 threads, while the U302L has 5 cores and 6 threads. This indicates the X9 378H uses a design without simultaneous multithreading (16 threads equal 16 cores), whereas the U302L has a configuration where 6 threads exceed its 5 cores, implying at least one core supports two threads.

Clock speeds also separate the two. The X9 378H has a base clock of 2.00 GHz and a boost clock of 5.00 GHz. The U302L has a base clock of 1.20 GHz and a boost clock of 2.40 GHz. The X9 378H thus offers a 2.6 GHz higher boost ceiling. Cache hierarchies diverge as well: the X9 378H provides 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The U302L provides 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 10 MB of shared L3 cache. The X9 378H has nearly 1.8 times the L3 cache total. Memory support differs: the X9 378H supports LPDDR5X memory with dual-channel configuration and a memory bandwidth of 153.6 GB/s, while the U302L supports DDR4 and DDR5 with dual-channel configuration and no recorded bandwidth figure. Both disable ECC memory. PCIe interfaces differ: the X9 378H uses Gen 5 with 4 lanes (CPU only), while the U302L uses Gen 4 with 8 lanes (CPU only). Integrated graphics also differ: the X9 378H features Arc B390, while the U302L features UHD Graphics 80EU. Sockets are not shared: the X9 378H uses Intel BGA 2540, and the U302L uses Intel Socket 1700. Release dates differ by nearly two years: the X9 378H released on 2026-04-03, and the U302L released on 2024-04-07. The U302L has a launch MSRP of $285, while the X9 378H has no recorded launch MSRP. The U302L has a part number (SRPKGQ5CX), while the X9 378H has an unknown part number. Both are mobile segment parts, both are active in production, and both have locked multipliers.

Where Each One Wins

The X9 378H wins in every benchmark category where data exists. Its Cinebench R15 multicore score is 3,281, and its single-core score is 462. In Cinebench R20, it records 13,672 multicore and 1,929 single-core. In Cinebench R23, it reaches 32,553 multicore and 4,595 single-core. Passmark results show data compression at 386,591, data encryption at 29,840, extended instructions at 31,315, prime number finding at 357, floating point math at 114,500, integer math at 92,603, multithread at 38,298, physics at 3,404, random string sorting at 44,648, and single-thread at 4,453. The U302L has no benchmark entries in any test, so it cannot claim a single recorded win.

The U302L wins only in specifications that favor efficiency and platform compatibility. Its thermal design power of 15 watts is lower than the X9 378H's 25 watts, which suggests it can operate in cooler, quieter, or more power-constrained environments. Its PCIe Gen 4 with 8 lanes doubles the lane count of the X9 378H's Gen 5 with 4 lanes, though the older generation means lower per-lane bandwidth. Its support for DDR4 memory gives it compatibility with older memory modules, whereas the X9 378H exclusively supports LPDDR5X. Its earlier release date (2024-04-07 versus 2026-04-03) means it has been available longer. Its Socket 1700 platform may be more common in existing systems, but the database does not provide compatibility data for either socket beyond their names.

For compute-heavy workflows such as rendering, encryption, compression, and mathematical operations, the X9 378H is the clear performer based on its recorded scores. For workloads that rely on modest power draw and broad memory compatibility, the U302L offers a different profile, but without benchmark evidence, its actual compute capabilities cannot be quantified from the database.

Head-to-Head Benchmarks

The head-to-head benchmark list in the database is empty, and the win counts for both processors are zero. This means no direct comparative test results exist between the Intel Core Ultra X9 378H and the Intel Processor U302L. The only performance data available belongs to the X9 378H, whose individual benchmark scores can be examined independently.

The X9 378H's Cinebench R23 multicore score of 32,553 places it in a high-performance tier. Its single-core score of 4,595 in the same test indicates strong per-thread performance. The Cinebench R20 results show 13,672 multicore and 1,929 single-core, while R15 shows 3,281 multicore and 462 single-core. These scores scale consistently with the core count and clock speed.

Passmark results reinforce the pattern. The multithread score of 38,298 and single-thread score of 4,453 show a 8.6 times difference between multi and single-thread performance, which aligns with a 16-core design. Data compression at 386,591 and data encryption at 29,840 demonstrate strong throughput for those specific workloads. Floating point math at 114,500 and integer math at 92,603 show higher floating point capability. Random string sorting at 44,648 and extended instructions at 31,315 round out the suite. Physics at 3,404 and prime number finding at 357 are the lower scores in the set.

The nearest rivals for the X9 378H provide context for these numbers. The AMD Ryzen 9 PRO 5945 averages 47,527, which is 0.1% higher than the X9 378H's 47,468. The Intel Core i7-13700KF averages 47,330, which is 0.3% lower. The Intel Core Ultra 7 265T averages 47,697, which is 0.5% higher. The Intel Core i9-12900F averages 47,176, which is 0.6% lower. These deltas show the X9 378H performing statistically on par with a set of established high-end processors, none of which deviate from its average by more than 0.6%. The U302L has no average score and no rivals, so it cannot be placed in any comparative ranking.
