Specification Differences

The two processors differ in several fundamental specifications. The Intel Core 3 305 has 6 cores and 6 threads, while the Intel Core 7 160UL has 10 cores and 12 threads. The base clocks differ: the Core 3 305 runs at 1.50 GHz, while the Core 7 160UL runs at 1.80 GHz. The boost clocks show the Core 7 160UL with a higher 5.20 GHz compared to the Core 3 305's 4.30 GHz. Both processors have a TDP of 15 watts.

The socket types are different. The Core 3 305 uses Intel BGA 1516, which is a mobile socket, while the Core 7 160UL uses Intel Socket 1700, a desktop socket. This aligns with their market segments: the Core 3 305 is classified as Mobile, and the Core 7 160UL is classified as Desktop. The memory support also differs, with the Core 3 305 supporting DDR5 and LPDDR5X in a single-channel configuration, while the Core 7 160UL supports DDR4 and DDR5 in a dual-channel configuration. The Core 3 305 has a memory bandwidth of 59.7 GB/s, while the Core 7 160UL's memory bandwidth is not recorded. The PCIe configurations differ as well: the Core 3 305 has Gen 4 with 6 lanes, while the Core 7 160UL has Gen 4 with 8 lanes.

The integrated graphics are different. The Core 3 305 uses Intel Xe3 Graphics with 1 Xe core, while the Core 7 160UL uses Iris Xe Graphics with 96 execution units. The release dates show the Core 7 160UL launched in April 2024, while the Core 3 305 has a release date of April 2026. The Core 3 305 has a recorded launch MSRP of $309, while the Core 7 160UL has no launch MSRP listed.

Architecture Differences

The architectural divide between the two processors is substantial. The Intel Core 3 305 is based on the Wildcat Lake codename and is built on a 3 nm process node. It has no recorded architecture name but is listed as part of the Core 3 (Wildcat Lake) generation. The Intel Core 7 160UL is based on the Raptor Lake architecture, specifically the Raptor Lake-PS codename, and is built on a 10 nm process node. This process node difference is likely a major factor in the performance gap, as the 3 nm node allows for much greater transistor density and power efficiency.

The cache hierarchies are structured differently. The Core 3 305 has a total L1 cache of 192 KB, an L2 cache of 2.5 MB, and a 6 MB shared L3 cache. The Core 7 160UL has an L1 cache of 80 KB per core, an L2 cache of 1.25 MB per core, and a 12 MB shared L3 cache. The Core 7 160UL's larger L3 cache is a significant advantage in theory, but the benchmark data does not show this translating into better performance outside of the integer math test. The Core 3 305's smaller but more efficient cache design, combined with the newer process node, appears to be more effective in practice.

The instruction set performance, as measured by the PassMark extended instructions test, shows a massive difference. The Core 3 305 scores 13,543, which is 132.2% higher than the Core 7 160UL's 5,832. This suggests the Wildcat Lake architecture has significantly better support for modern instruction extensions, which could explain its dominance in encryption, floating-point math, and physics simulations. The Core 7 160UL, despite having more cores and a higher boost clock, cannot compensate for this architectural deficit in most workloads.

The Verdict

The benchmark data indicates that the Intel Core 3 305 is the superior processor for the vast majority of tasks, despite having fewer cores and threads. Its consistent 39.8% lead across Cinebench tests, both single and multi-core, shows that its 3 nm architecture is far more efficient than the older 10 nm Raptor Lake design. For workloads involving rendering, data compression, encryption, physics, and general single-threaded performance, the Core 3 305 is the clear choice based on the recorded scores.

The Intel Core 7 160UL should be considered only for tasks that are heavily dependent on integer math operations. Its 32% lead in the PassMark integer math test is its only advantage. For users whose primary workload involves such calculations, the Core 7 160UL may offer better performance. However, this is a narrow use case, and the Core 3 305's dominance in every other recorded benchmark makes it the more versatile processor. The Core 3 305 also holds a higher percentile ranking, 72nd versus 69th, and a higher average benchmark score of 18,302 versus 14,232. The data clearly points to the Core 3 305 as the stronger overall performer in this comparison.
