Where Each One Wins

The Intel Core 3 305 demonstrates clear strengths in mobile-oriented workloads based on its recorded benchmark results. Its PassMark data compression score of 146857 shows robust throughput for data-intensive tasks. The floating point math result of 42284 and integer math score of 32295 indicate solid computational capability for general processing. The extended instructions score of 13543 supports workloads that leverage modern CPU instruction sets.

The Core i5-14501E has no recorded benchmark wins in the database, so its performance profile cannot be established from measurements. What the data does show is that the Core i5-14501E targets a different market segment entirely. It is classified as a desktop processor with a 65 TDP, whereas the Core 3 305 is a mobile part with a 15 TDP. The Core i5-14501E offers 12 threads compared to the Core 3 305's 6 threads, and it boosts to 5.20 GHz versus 4.30 GHz. These specifications suggest the desktop chip would likely perform differently in multi-threaded scenarios, but without benchmark data, this remains speculative.

The Core 3 305's PassMark physics score of 1233 and prime number finding score of 115 are the only direct productivity measurements recorded. The random string sorting score of 17623 rounds out its algorithmic performance picture. Since the Core i5-14501E has zero recorded scores, the Core 3 305 wins every measurable category by default.

Architecture Differences

The two processors come from fundamentally 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 foundry. The Intel Core i5-14501E belongs to the Raptor Lake architecture, specifically Raptor Lake-R, manufactured on a 10 nm process. The Core 3 305's generation is listed as "Core 3 (Wildcat Lake)" while the Core i5-14501E is part of "Core i5 (Raptor Lake Refresh)".

Cache configurations differ substantially between the two. The Core 3 305 has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Core i5-14501E lists 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 24 MB of shared L3 cache. The desktop chip's larger L3 pool reflects its higher-thread-count design and desktop performance ambitions.

Memory support marks a clear division. The Core 3 305 supports DDR5 and LPDDR5X memory with a single-channel bus and 59.7 GB/s bandwidth. The Core i5-14501E supports both DDR4 and DDR5 through a dual-channel memory bus, though no bandwidth figure is recorded. The Core i5-14501E also supports ECC memory while the Core 3 305 does not.

PCIe capabilities differ significantly. The Core 3 305 provides Gen 4 with 6 lanes from the CPU, while the Core i5-14501E offers Gen 5 with 16 lanes. Integrated graphics also diverge: the Core 3 305 uses Intel Xe3 Graphics with 1 Xe core, while the Core i5-14501E uses UHD Graphics 770.

The Core i5-14501E has a recorded die size of 215 mm², while the Core 3 305 has no die size listed. Both processors are actively in production, but their release dates differ. The Core i5-14501E appeared on 2024-06-30, while the Core 3 305 arrived later on 2026-04-15.
