Intel Core Ultra 5 338H vs Intel Processor U302L Comparison

Head-to-Head Benchmarks

The direct comparison between the Intel Core Ultra 5 338H and the Intel Processor U302L is complicated by a critical data gap: the database contains no benchmark records for the U302L. Its average benchmark score is recorded as zero, and no individual test results exist. This means a traditional head-to-head, where each processor's scores are placed side by side, cannot be constructed from the recorded data. The Core Ultra 5 338H, by contrast, has a full suite of measurements.

What the data does show is the absolute performance level of the Core Ultra 5 338H. In Cinebench R23, it scores 16,331 points in the multi-core test and 2,044 points in the single-core test. In the older Cinebench R20 suite, it reaches 10,213 multi-core and 1,441 single-core. The R15 results are 2,504 multi-core and 305 single-core. These are substantial figures for a 25-watt mobile processor.

The PassMark suite reinforces this. The Core Ultra 5 338H records 28,717 in the multithread test and 4,180 in the single-thread test. Its integer math score is 64,934, while floating-point math reaches 84,067. Data compression hits 276,539, and data encryption scores 21,367. Extended instructions land at 23,906, with random string sorting at 34,082. Prime number finding is the outlier at 304, and physics simulation scores 2,697.

Because the U302L has no recorded benchmarks, the database's percentile rankings provide the only relative context. The Core Ultra 5 338H sits at the 84th percentile among all CPUs. The U302L sits at the 50th percentile. That 34-point percentile gap is the closest thing to a head-to-head measurement available in the data.

The Core Ultra 5 338H's nearest rivals in the database offer a sense of its competitive position. The Intel Core Ultra 7 165H averages 34,083, which is 0.3% lower than the 338H's average of 33,989. The Intel Core i7-12800HX averages 33,875, 0.3% higher than the 338H. The Intel Xeon 6353P averages 33,844, 0.4% higher. The AMD EPYC 4244P averages 34,220, 0.7% lower. These margins are small, clustering within one percentage point. The 338H therefore performs in line with a broad group of established desktop and mobile processors, despite its lower power envelope.

The absence of U302L data means no exact percentage deltas can be computed against it. The analysis must rely on the structural specifications and the percentile difference alone.

Architecture Differences

The two processors come from different architectural generations and are built on different nodes. The Core Ultra 5 338H uses the Panther Lake architecture, specifically the Panther Lake-H generation, and is fabricated on a 3 nm process. The Intel Processor U302L uses the Raptor Lake architecture, specifically Raptor Lake-PS, on a 10 nm process. Both are manufactured by Intel, but the node difference is substantial: 3 nm versus 10 nm.

Core counts differ sharply. The 338H has 12 cores and 12 threads, meaning no hyperthreading is enabled. The U302L has 5 cores and 6 threads, indicating that one core has two threads while the others have one each. The 338H's base clock is 1.90 GHz with a boost clock of 4.70 GHz. The U302L's base clock is 1.20 GHz with a boost clock of 2.40 GHz. The 338H therefore has both a higher floor and a much higher ceiling.

Cache hierarchies also differ. The 338H has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The U302L has 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3. Per-core L1 is 2.4 times larger on the 338H, and per-core L2 is double. Total L3 is 18 MB versus 10 MB.

The memory controllers reflect different design targets. The 338H uses LPDDR5X exclusively, with a recorded bandwidth of 136.5 GB/s. The U302L supports both DDR4 and DDR5, with no bandwidth figure recorded. Both use dual-channel memory buses.

PCI Express support differs in both generation and lane count. The 338H uses Gen 5 with 4 CPU lanes. The U302L uses Gen 4 with 8 CPU lanes. The 338H has fewer lanes but a newer generation.

Integrated graphics are completely different. The 338H carries an Arc B370 GPU. The U302L carries UHD Graphics 80EU. The sockets also differ: the 338H uses Intel BGA 2540, while the U302L uses Intel Socket 1700. The 338H's TDP is 25 watts; the U302L's is 15 watts.

The Verdict

The recorded data supports a clear split between these two processors. The Core Ultra 5 338H is the higher-performing part by every measurable specification. It has more cores, more threads, higher clocks, more cache, a newer process node, and a higher percentile ranking. Its 84th percentile placement against all CPUs, combined with an average benchmark score of 33,989, places it in the upper tier of mobile processors. Its nearest rivals, all within one percentage point of its average score, include the Core Ultra 7 165H and the Core i7-12800HX, both well-regarded parts in their own right.

The Intel Processor U302L occupies a different position. Its 50th percentile ranking means it sits exactly at the median of all CPUs. With 5 cores and 6 threads, a 2.40 GHz boost clock, and 10 MB of L3 cache, it is clearly a lower-tier mobile part. The absence of any benchmark data in the database means its real-world performance cannot be verified from the recorded measurements, but its specifications suggest it is aimed at workloads with modest thread requirements.

The choice between them depends on which specifications matter more. The 338H delivers a wider performance envelope, higher bandwidth memory support, and a much newer GPU. The U302L offers a lower TDP, DDR4 compatibility, and a different socket. Neither processor supports ECC memory, and neither has an unlocked multiplier.

For applications that scale with core count and clock speed, the 338H is the obvious pick. Its 12 cores, 4.70 GHz boost, and 18 MB of L3 cache give it a structural advantage that the U302L cannot match. For low-power or embedded-style deployments where 15 watts is a hard limit and DDR4 support is required, the U302L has a role. The data does not support any claim that the U302L can compete with the 338H on raw performance, because no benchmark records exist to contradict the specification gap.

Where Each One Wins

The Core Ultra 5 338H wins in every category where the database has recorded a measurement. Its 12 cores and 12 threads provide double the core count of the U302L. Its boost clock of 4.70 GHz is nearly double the U302L's 2.40 GHz. Its 18 MB of L3 cache is 80% larger. Its 3 nm process node is two generations ahead of the U302L's 10 nm node, which typically indicates better power efficiency per unit of work, though the database does not record efficiency metrics directly.

Its memory subsystem is also stronger on paper. The 338H's LPDDR5X support with 136.5 GB/s of bandwidth gives it a clear advantage for memory-intensive tasks. The U302L's DDR4 and DDR5 support has no recorded bandwidth figure, so no direct comparison is possible, but the 338H's bandwidth number is high for a mobile part.

The integrated GPU is another clear win. The Arc B370 in the 338H is a distinct GPU model with no performance data recorded in the database, but the U302L's UHD Graphics 80EU is a lower-tier integrated solution. The 338H's GPU is likely to handle more demanding display and media workloads.

The U302L has its own advantages, though they are narrower. Its 15-watt TDP is 10 watts lower than the 338H's 25 watts, which matters in thermally constrained systems. It supports both DDR4 and DDR5, giving system designers memory flexibility that the 338H lacks. Its PCIe Gen 4 with 8 lanes doubles the lane count of the 338H's Gen 5 with 4 lanes, which could benefit systems needing more direct device connections. Its Socket 1700 form factor may be easier to integrate into existing designs, and its earlier release date of 2024-04-07 means it has been on the market longer than the 338H's 2026-01-04 release.

The database's percentile rankings summarize the gap. The 338H's 84th percentile versus the U302L's 50th percentile means the 338H outperforms a much larger share of all CPUs. The U302L, at the median, delivers average performance relative to the broader CPU landscape.

For workloads like 3D rendering, video encoding, software compilation, and scientific computing, the 338H's core count and clock speed make it the stronger candidate. For lightweight office tasks, basic web browsing, or single-threaded legacy applications where power draw is a concern, the U302L's lower TDP and simpler architecture may suffice. The data, however, only confirms the 338H's performance. The U302L's actual benchmark behavior remains unmeasured in the database.
