Intel Core i5-14401E vs Intel Processor U302L Comparison

Head-to-Head Benchmarks

The Intel Core i5-14401E and Intel Processor U302L are both Raptor Lake parts on the Intel Socket 1700 platform, but they target very different segments. The recorded benchmark data shows a decisive gap between them, though the comparison is limited by the fact that the U302L has no benchmark entries in the database.

The i5-14401E delivers a Cinebench R23 multi-core score of 18,161 and a single-core score of 2,564. Its Cinebench R20 results are 7,627 multi-core and 1,076 single-core. In Cinebench R15, it posts 1,830 multi-core and 258 single-core. The U302L has no recorded scores in any of these tests, so the database cannot produce head-to-head delta percentages or win counts. The winsA and winsB fields are both zero, reflecting this absence of direct comparative data.

What the database does show is the i5-14401E's position against other processors. Its average benchmark score of 5,253 places it at the 60th percentile among all CPUs. The nearest rivals are tightly clustered: the Intel Xeon E5-2699A v4 scores 5,259, which is 0.1% faster; the Intel Core i7-11700B scores 5,241, 0.2% slower; the Intel Core i9-10850K scores 5,240, 0.2% slower; and the Intel Core i5-13400T scores 5,210, 0.8% slower. This indicates the i5-14401E sits within a narrow performance band around the 5,200 to 5,260 average score range.

The U302L, by contrast, has an average benchmark score of 0 and a percentile ranking of 50, which is misleading because the percentile is assigned without any actual test data. The database records no nearest rivals for the U302L, meaning there is no comparative performance context available. This is a mobile processor with a 15 TDP, while the i5-14401E is a desktop part with a 65 TDP, and the benchmark absence likely reflects the U302L's role in low-power systems where synthetic CPU workloads are not the primary focus.

Where Each One Wins

The i5-14401E wins in every measurable category simply because it has measured data. Its 6 cores and 12 threads provide a clear advantage in multi-threaded workloads. The Cinebench R23 multi-core score of 18,161 is roughly seven times the single-core score of 2,564, showing strong scaling across its 12 threads. This makes it suited for rendering, compilation, and other parallel tasks.

The U302L, with 5 cores and 6 threads, would logically fall behind in such workloads, but the database cannot quantify the difference. Its boost clock of 2.40 GHz is well below the i5-14401E's 4.70 GHz, and its base clock of 1.20 GHz is less than half of the i5-14401E's 2.50 GHz. The U302L's single-core performance would presumably be limited by those clocks, but without benchmark scores, the database can only note the specification gap.

The U302L's wins are in power consumption and mobility. Its 15 TDP is drastically lower than the 65 TDP of the i5-14401E. It is classified as a mobile part, which means it is designed for laptops and compact systems where heat and battery life matter more than raw throughput. The i5-14401E is a desktop part, requiring a larger cooling solution and more power delivery. The U302L also supports only 8 PCIe Gen 4 lanes from the CPU, while the i5-14401E provides 16 Gen 5 lanes, so the U302L is not intended for high-bandwidth expansion cards.

Architecture Differences

Both processors use Intel's 10 nm process node and are built on the Raptor Lake architecture. The i5-14401E carries the Raptor Lake-R codename and belongs to the Core i5 (Raptor Lake Refresh) generation, while the U302L uses the Raptor Lake-PS codename and is labeled simply as Intel Processor (Raptor Lake). Both are fabricated by Intel.

The core configurations differ significantly. The i5-14401E has 6 cores and 12 threads, meaning it uses hyper-threading across all cores. The U302L has 5 cores and 6 threads, which indicates only one of its cores supports hyper-threading, or the design uses a heterogeneous layout. The database does not specify performance versus efficiency core counts, so the exact arrangement is not confirmed.

Cache hierarchies share the same per-core L1 and L2 sizes: 80 KB and 1.25 MB per core respectively. The L3 cache differs, with the i5-14401E offering 20 MB shared versus the U302L's 10 MB shared. This gives the i5-14401E twice the last-level cache, which benefits workloads with large working sets and inter-core communication.

Memory support is identical in type: both support DDR4 and DDR5 with dual-channel memory buses. ECC memory support differs, with the i5-14401E supporting ECC while the U302L does not. This makes the i5-14401E suitable for workstation or server-adjacent builds where error-correcting memory is required.

Integrated graphics also differ. The i5-14401E uses UHD Graphics 730, while the U302L uses UHD Graphics 80EU. The 80EU designation suggests a higher execution unit count, but the database does not provide specific EU numbers for the i5-14401E, so a direct comparison of graphics capability is not possible from the recorded data.

PCIe support is a major differentiator. The i5-14401E provides Gen 5 with 16 lanes from the CPU, while the U302L provides Gen 4 with 8 lanes. This impacts storage and GPU bandwidth, with the i5-14401E supporting the latest high-speed devices.

The Verdict

The data clearly favors the Intel Core i5-14401E for any workload that requires processing power. Its 6 cores, 12 threads, 4.70 GHz boost clock, and 20 MB L3 cache put it in a different performance class than the U302L. The Cinebench scores, while only recorded for the i5-14401E, establish a baseline of strong multi-core and single-core capability. The 60th percentile ranking and the tight cluster of nearest rivals around the 5,250 average score mark confirm that this processor competes with established desktop CPUs like the Core i9-10850K and Core i7-11700B.

The Intel Processor U302L is a different kind of product. Its 5 cores, 6 threads, 1.20 GHz base clock, and 2.40 GHz boost clock, combined with a 15 TDP, make it a low-power mobile processor. The absence of benchmark data means the database cannot quantify its performance, but the specifications suggest it is designed for efficiency rather than speed. Its 10 MB L3 cache and 8 PCIe Gen 4 lanes are adequate for a mobile platform but limited for desktop use.

The choice depends on the intended system. For a desktop build where performance is the priority, the i5-14401E is the only option with recorded evidence to support it. For a mobile or ultra-low-power system, the U302L's 15 TDP and mobile classification make it the appropriate part, though no benchmark data exists to validate its real-world speed. The i5-14401E also supports ECC memory and PCIe Gen 5, while the U302L does not, further cementing the desktop part as the more capable processor.
