Intel Core 3 305 vs Intel Processor U302L Comparison

Head-to-Head Benchmarks

The database shows a clear performance gap between the Intel Core 3 305 and the Intel Processor U302L, though direct comparison is limited by a lack of recorded benchmark data for the U302L. The Core 3 305 has a substantial number of measured results across Cinebench and Passmark tests, while the U302L currently has no benchmark entries in the database. This absence of data for the U302L means the head-to-head comparison relies on the Core 3 305's recorded scores and the architectural specifications of both processors.

The Core 3 305 posts a Cinebench R23 multi-core score of 13123 and a single-core score of 1852. Its Cinebench R20 results show 5511 in multi-core and 777 in single-core, while Cinebench R15 delivers 1322 and 186 respectively. These figures position the Core 3 305 at the 72nd percentile among all CPUs in the database, with an average benchmark score of 18302. The nearest rival, the Intel Core i3-14100, scores 18318, a delta of -0.1%, meaning the Core 3 305 trails by only a tenth of a percent. The Intel Core 5 330 sits at 18345 (delta -0.2%), the Intel Core 7 360 at 18374 (delta -0.4%), and the AMD Ryzen 5 2600E at 18230 (delta 0.4%). These deltas indicate the Core 3 305 sits within a narrow competitive band, effectively matching the Core i3-14100 and slightly trailing the Core 5 330 and Core 7 360 while edging out the Ryzen 5 2600E.

Passmark results for the Core 3 305 show a multi-thread score of 15439 and a single-thread score of 3977. Data compression reaches 146857, data encryption hits 11019, and extended instructions score 13543. Floating point math delivers 42284, integer math scores 32295, and physics reaches 1233. Random string sorting completes at 17623, while finding prime numbers scores 115. These numbers represent the only measured performance data available for this comparison, as the U302L has no recorded benchmark scores.

The U302L's lack of benchmark data means its performance cannot be quantified against the Core 3 305. Its percentile rank of 50th among all CPUs, however, provides a general placement that is notably lower than the Core 3 305's 72nd percentile. This percentile difference suggests the Core 3 305 should outperform the U302L across most workloads, but without direct measurements, the exact margins remain unspecified in the database.

Architecture Differences

The two processors diverge significantly in their underlying designs. The Intel Core 3 305 uses the Wildcat Lake codename, built on a 3 nm process node, while the Intel Processor U302L uses the Raptor Lake architecture, specifically the Raptor Lake-PS codename, on a 10 nm node. Both are manufactured by Intel, but the process node difference represents a substantial generational leap for the Core 3 305. The Core 3 305's generation is listed as "Core 3 (Wildcat Lake)" while the U302L is listed as "Intel Processor (Raptor Lake)".

Core and thread counts differ as well. The Core 3 305 has 6 cores and 6 threads, while the U302L has 5 cores and 6 threads. The U302L's extra thread relative to its core count indicates hyper-threading on some cores, whereas the Core 3 305 operates with one thread per core. Clock speeds favor the Core 3 305 substantially: its base clock is 1.50 GHz and boost clock reaches 4.30 GHz, compared to the U302L's 1.20 GHz base and 2.40 GHz boost. That boost clock gap of nearly 2 GHz gives the Core 3 305 a major frequency advantage in single-threaded and lightly threaded workloads.

Cache configurations also differ considerably. The Core 3 305 has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The U302L lists L1 cache as 80 KB per core, L2 cache as 1.25 MB per core, and 10 MB of shared L3 cache. While the U302L's per-core L2 allocation is larger, the Core 3 305's total L2 cache (2.5 MB across 6 cores) is smaller than the U302L's total L2 (which would be roughly 6.25 MB across 5 cores based on the per-core figure). The U302L's 10 MB shared L3 cache exceeds the Core 3 305's 6 MB shared L3, suggesting the U302L may have an advantage in cache-heavy workloads despite its lower clock speeds.

Memory support differs as well. The Core 3 305 supports DDR5 and LPDDR5X memory with a single-channel memory bus and a memory bandwidth of 59.7 GB/s. The U302L supports DDR4 and DDR5 with a dual-channel memory bus, though its memory bandwidth is not recorded in the database. The dual-channel configuration of the U302L could provide higher memory throughput in practice, but without a bandwidth figure, this remains qualitative. The Core 3 305's single-channel bus is a notable limitation, particularly for memory-intensive applications.

PCIe connectivity also varies. The Core 3 305 provides PCIe Gen 4 with 6 lanes (CPU only), while the U302L offers PCIe Gen 4 with 8 lanes (CPU only). The U302L's additional PCIe lanes could support more expansion devices or faster data transfer to peripherals. Integrated graphics differ as well: the Core 3 305 uses Intel Xe3 Graphics with 1 Xe core, while the U302L uses UHD Graphics 80EU. The Xe3 architecture represents a newer graphics generation, though the 80EU count on the U302L suggests more execution units. Neither processor supports ECC memory.

Socket compatibility is distinct: the Core 3 305 uses Intel BGA 1516, while the U302L uses Intel Socket 1700. This means the two processors are not interchangeable in the same motherboard. The Core 3 305's release date is recorded as April 15, 2026, while the U302L's is April 7, 2024. The Core 3 305 launches with an MSRP of $309, and the U302L with an MSRP of $285. Both processors have active production status and locked multipliers.

Where Each One Wins

Based on the recorded data, the Intel Core 3 305 wins in raw computational performance. Its Cinebench scores, Passmark multi-thread and single-thread scores, and 72nd percentile ranking all indicate superior throughput compared to the U302L's 50th percentile placement. The Core 3 305's boost clock of 4.30 GHz versus the U302L's 2.40 GHz gives it a decisive advantage in single-threaded tasks, which is reflected in its Cinebench R23 single-core score of 1852 and Passmark single-thread score of 3977. For workloads like web browsing, office productivity, and lightly threaded applications that depend on high clock speeds, the Core 3 305 should deliver noticeably faster response times.

The Core 3 305 also wins in multi-core workloads. Its 6 cores and 6 threads, combined with the 3 nm process node and higher boost clock, produce a Cinebench R23 multi-core score of 13123. This performance level places it near the Intel Core i3-14100 and Intel Core 5 330 in the database's nearest rivals list, suggesting it can handle moderately parallel tasks like video encoding, 3D rendering, and software compilation effectively. The Passmark multi-thread score of 15439 reinforces this capability.

The Intel Processor U302L has potential advantages in specific areas, though the lack of benchmark data prevents quantitative confirmation. Its larger shared L3 cache of 10 MB compared to the Core 3 305's 6 MB could benefit workloads with large working sets that reuse data frequently, such as database queries or certain scientific simulations. The dual-channel memory bus, compared to the Core 3 305's single-channel bus, could provide higher memory bandwidth for memory-bound tasks, though the Core 3 305's recorded 59.7 GB/s bandwidth sets a baseline that the U302L may or may not exceed. The U302L's 8 PCIe Gen 4 lanes versus the Core 3 305's 6 lanes could support additional NVMe storage or other expansion cards, making it a more flexible platform for systems with multiple peripherals.

The U302L's higher per-core L2 cache allocation (1.25 MB per core versus the Core 3 305's total 2.5 MB) could also help in certain cache-sensitive workloads. However, the U302L's lower clock speeds and older 10 nm process node likely offset these advantages in most real-world scenarios. The Core 3 305's newer 3 nm process node should provide better power efficiency per unit of performance, though both processors share a 15 W TDP.

The Verdict

The data clearly favors the Intel Core 3 305 for users prioritizing raw performance. Its 72nd percentile ranking, substantial Cinebench and Passmark scores, and higher clock speeds make it the stronger choice for both single-threaded and multi-threaded workloads. The 3 nm process node and newer Wildcat Lake architecture provide a modern foundation that should deliver efficient operation within the 15 W TDP. The Core 3 305's nearest rival comparisons show it performs essentially on par with the Intel Core i3-14100 and slightly below the Intel Core 5 330 and Core 7 360, making it a competitive mid-range mobile processor.

The Intel Processor U302L, with its 50th percentile ranking and no recorded benchmark scores, lacks demonstrated performance credentials. Its advantages are structural rather than measured: the dual-channel memory bus, larger shared L3 cache of 10 MB, and 8 PCIe Gen 4 lanes could benefit specific use cases like memory-heavy applications or systems with multiple expansion devices. The larger per-core L2 cache allocation may also help in certain workloads. However, the 10 nm process node and lower boost clock of 2.40 GHz represent significant handicaps that likely negate these structural advantages in most scenarios.

For users who need a processor with proven performance in compression, encryption, floating-point math, integer math, and multi-threaded rendering tasks, the Intel Core 3 305 is the only option with measurable data supporting its capability. Its Cinebench R23 multi-core score of 13123 and Passmark multi-thread score of 15439 indicate solid throughput for a 15 W mobile processor. The single-thread scores of 1852 and 3977 respectively confirm strong responsiveness in everyday tasks.

The U302L may appeal to users who require dual-channel memory support or additional PCIe lanes without needing maximum clock speeds. Its compatibility with DDR4 memory could also make it a more practical choice for systems using older memory modules. However, the lack of benchmark data means these potential advantages cannot be verified, and its lower percentile ranking suggests it sits below the Core 3 305 in overall capability.

The database shows no head-to-head benchmark results or wins for either processor, leaving the Core 3 305 as the default performance pick based on the available measurements. The U302L remains an unquantified option whose suitability depends entirely on workload characteristics that favor its cache and memory configuration. For most users, the Core 3 305's recorded performance and newer architecture make it the more compelling choice.
