Intel Core 3 305 vs Intel Processor U301L Comparison

Head-to-Head Benchmarks

The database contains a complete set of benchmark results for the Intel Core 3 305, while the Intel Processor U301L has no recorded scores in the current dataset. This makes a direct statistical comparison impossible, but the available data for the Core 3 305 positions it clearly in the performance hierarchy. The Core 3 305 achieves an average benchmark score of 18,302 across all recorded tests, placing it in the 72nd percentile of all CPUs in the database. Its nearest rivals include the Intel Core i3-14100 with an average score of 18,318 and a delta of -0.1%, the Intel Core 5 330 with 18,345 and -0.2%, and the Intel Core 7 360 with 18,374 and -0.4%. The AMD Ryzen 5 2600E sits just below with 18,230 and a delta of +0.4%. The Core 3 305 is therefore statistically indistinguishable from these four rivals, with all deltas under 0.5%.

For the Core 3 305, multi-threaded performance is strong in Cinebench tests. The Cinebench R23 multi-core score is 13,123 points, while the single-core score is 1,852 points. The Cinebench R20 results show 5,511 for multi-core and 777 for single-core, and the older Cinebench R15 test yields 1,322 multi-core and 186 single-core. PassMark tests further characterize the chip: integer math scores 32,295, floating point math scores 42,284, and extended instructions score 13,543. Data compression reaches 146,857, and data encryption scores 11,019. The single-thread PassMark score is 3,977, while multithreaded PassMark shows 15,439. Physics simulation scores 1,233, find prime numbers scores 115, and random string sorting scores 17,623.

Because the U301L has no benchmark entries, the data cannot show any head-to-head wins for either part. The Core 3 305's scores stand alone as the only measurable performance data in this comparison.

Architecture Differences

The two processors come from different design lineages. The Intel Core 3 305 uses the Wildcat Lake codename and is built on a 3 nm process node at Intel's own foundry. The Intel Processor U301L uses the Raptor Lake architecture with the Raptor Lake-PS codename and is manufactured on a 10 nm process, also at Intel. The Core 3 305 belongs to the Core 3 (Wildcat Lake) generation, while the U301L belongs to the Intel Processor (Raptor Lake) generation.

Core counts differ. The Core 3 305 has 6 cores and 6 threads. The U301L has 5 cores and 6 threads, indicating that one of its cores supports two threads via hyperthreading, while the Core 3 305 uses a 1:1 core-to-thread ratio. Clock speeds diverge significantly. The Core 3 305 has a base clock of 1.50 GHz and a boost clock of 4.30 GHz. The U301L has a base clock of 1.20 GHz and a boost clock of 2.20 GHz. The boost differential of 2.10 GHz favors the Core 3 305 substantially.

Cache hierarchies are organized differently. The Core 3 305 has an L1 cache of 192 KB, an L2 cache of 2.5 MB, and a shared L3 cache of 6 MB. The U301L lists its L1 cache as 80 KB per core and its L2 cache as 1.25 MB per core, with a shared L3 cache of 8 MB. The total L2 capacity for the U301L would scale with its 5 cores, though the database records per-core figures. The Core 3 305's larger shared L3 of 6 MB versus the U301L's 8 MB is a notable inversion, though the different core counts and cache organizations make direct comparisons complex.

Memory support differs. The Core 3 305 supports DDR5 and LPDDR5X memory over a single-channel interface with a recorded bandwidth of 59.7 GB/s. The U301L supports both DDR4 and DDR5 across a dual-channel interface, though its bandwidth figure is not recorded. PCIe connectivity also differs: the Core 3 305 provides Gen 4 with 6 lanes from the CPU, while the U301L provides Gen 4 with 8 lanes from the CPU. Neither supports ECC memory.

Integrated graphics differ. The Core 3 305 uses Intel Xe3 Graphics with 1 Xe core. The U301L uses UHD Graphics 64EU. Both target the mobile market segment and are currently in active production. Neither has an unlocked multiplier. The Core 3 305 uses the Intel BGA 1516 socket, while the U301L uses the Intel Socket 1700. The release dates differ: the Core 3 305 launched on 2026-04-15, and the U301L launched on 2024-04-07.

Where Each One Wins

Without benchmark data for the U301L, the analysis of wins must rely on architectural specifications. The Core 3 305 wins on raw clock speed. Its boost clock of 4.30 GHz versus 2.20 GHz on the U301L suggests a large advantage in burst workloads and single-threaded tasks. The base clock of 1.50 GHz versus 1.20 GHz also favors the Core 3 305 for sustained frequency in lightly threaded scenarios. The 3 nm process node versus the 10 nm node implies a more advanced manufacturing technology, which typically correlates with better transistor density and power characteristics at equivalent clock speeds.

The U301L wins on platform flexibility. It supports both DDR4 and DDR5 memory, whereas the Core 3 305 is limited to DDR5 and LPDDR5X. For systems still using DDR4 memory, the U301L offers a compatibility path that the Core 3 305 does not. The dual-channel memory interface on the U301L could benefit memory-bandwidth-sensitive workloads, although the Core 3 305's recorded bandwidth of 59.7 GB/s suggests it is not bandwidth-starved. The U301L also provides more PCIe lanes from the CPU: 8 lanes versus 6 lanes on the Core 3 305, which could matter for configurations with multiple Gen 4 devices. The U301L has a larger shared L3 cache of 8 MB versus 6 MB on the Core 3 305, potentially aiding workloads with larger working sets that fit in cache.

The Core 3 305 has 6 cores versus 5 on the U301L, giving it one additional physical core. In fully parallel workloads that scale with core count, the Core 3 305 has a structural advantage. The U301L's 6 threads match the Core 3 305's 6 threads because one U301L core is hyperthreaded, but physical core count remains lower. The Core 3 305's newer graphics architecture, Intel Xe3 Graphics with 1 Xe core, versus the U301L's UHD Graphics 64EU, suggests a generational difference in integrated graphics capability, though no graphics benchmarks are recorded for either part.

The two processors share several characteristics: both are mobile parts, both have a TDP of 15 watts, both lack ECC support, both have locked multipliers, and both come from Intel. The Core 3 305 is the newer and faster part on paper, with a higher base and boost clock, one additional core, and a more advanced process node. The U301L counters with a larger L3 cache, dual-channel memory support, more PCIe lanes, and a lower launch MSRP. The lack of benchmark data for the U301L means its actual performance relative to the Core 3 305 cannot be quantified from the database, but the architectural differences are clear.
