CPU Comparison

The Intel Core i7-1365U and Intel Core 5 320 are both 15 W mobile processors, yet the benchmark data reveals they are fundamentally different in character. The i7-1365U is a 10-core, 12-thread Raptor Lake-U part from 2023, while the Core 5 320 is a 6-core, 6-thread Wildcat Lake chip from 2026. What emerges from the head-to-head results is a split personality: the older chip wins on raw multi-core workloads in some tests, while the newer chip dominates in single-thread performance and a majority of synthetic tasks.

Head-to-Head Benchmarks

The most dramatic divergence appears in the Cinebench suite, where the two chips trade blows with massive margins. In Cinebench R23 multicore, the Intel Core i7-1365U scores 8946, a full 44.4% ahead of the Core 5 320’s 6197. This is the largest win for the i7 in the entire comparison. Similarly, in Cinebench R15 multicore, the i7-1365U posts 1466.5 against 1054, a 39.1% advantage. However, the story flips in Cinebench R20 multicore, where the Core 5 320 wins with 5462 versus 4882, a 10.6% margin. This inconsistency across Cinebench versions is curious, the older chip wins R15 and R23, but loses R20 despite the newer chip having fewer cores and threads.

Single-core results consistently favor the Core 5 320, though by smaller margins. In Cinebench R23 singlecore, the Core 5 320 scores 1926 versus 1887, a 2% edge. The gap widens in Cinebench R20 singlecore to 10.6% (771 vs 689) and narrows in R15 singlecore to 3.8% (276 vs 265.5). The PassMark single-thread test shows a more decisive 15.7% lead for the Core 5 320, with scores of 4045 and 3411 respectively.

The PassMark suite reveals the Core 5 320’s broader dominance. It wins 13 of the 17 head-to-head tests overall. The most striking PassMark results include extended instructions, where the Core 5 320 scores 13262 versus 8321, a 37.3% advantage. In find prime numbers, the Core 5 320 nearly doubles the i7-1365U, 110 to 58, a 47.3% gap. Floating point math also favors the Core 5 320 by 20.6% (42440 vs 33689), and physics by 20.9% (1221 vs 966).

The i7-1365U’s PassMark wins are fewer but notable. Integer math is its best showing, with 50881 versus 32323, a massive 57.4% lead. Data compression is nearly a tie, with the i7-1365U ahead by just 0.5% (149585 vs 148779). The passmark multithread test also goes to the Core 5 320, 15450 vs 14045, a 9.1% gap, despite the i7-1365U having twice the threads.

Where Each One Wins

The data suggests a clear use-case split. The Intel Core i7-1365U is the multi-threaded workhorse for specific integer-heavy and compression tasks. Its 57.4% lead in integer math indicates strong performance in workloads like data processing, spreadsheet calculations, or software compilation that rely on integer operations. The 0.5% edge in data compression, while slim, reinforces a slight advantage in archiving or file-handling scenarios. The 44.4% win in Cinebench R23 multicore also points to sustained multi-core rendering or video encoding potential.

The Intel Core 5 320 is the general-purpose performer with superior single-thread speed. The 15.7% lead in PassMark single-thread and consistent wins across single-core Cinebench tests suggest faster response in everyday applications, web browsing, and office productivity. Its 37.3% advantage in extended instructions and 47.3% in prime number finding indicate strength in encryption, scientific calculations, and workloads that leverage modern instruction sets. The 20.6% floating point math win and 20.9% physics win make it better suited for 3D modeling, physics simulations, and lighter content creation. The 13.2% data encryption lead (10984 vs 9531) further supports a security or networking use case.

Architecture Differences

The architectural divide is stark. The i7-1365U uses Intel’s 10 nm Raptor Lake process, while the Core 5 320 uses a 3 nm Wildcat Lake node. This node shrink likely explains the Core 5 320’s single-thread efficiency, but the core counts tell a different story. The i7-1365U has 10 cores and 12 threads, compared to the Core 5 320’s 6 cores and 6 threads. The i7-1365U also has a higher base clock of 1800 MHz versus 1500 MHz and a higher boost clock of 5.20 GHz versus 4.60 GHz.

Cache configurations differ significantly. The i7-1365U has 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The Core 5 320 has 192 KB of total L1, 2.5 MB of total L2, and 6 MB of shared L3. The i7-1365U’s larger L3 cache is a likely factor in its multi-core wins, while the Core 5 320’s newer architecture may compensate with better per-core efficiency.

Memory support also diverges. The i7-1365U supports DDR4 and DDR5 over a dual-channel bus. The Core 5 320 supports DDR5 and LPDDR5X over a single-channel bus, but with a specified memory bandwidth of 59.7 GB/s. The i7-1365U lists no memory bandwidth figure in the data. PCIe lanes differ: the i7-1365U has Gen 4 with 8 lanes, while the Core 5 320 has Gen 4 with 6 lanes.

Integrated graphics are another differentiator. The i7-1365U features Iris Xe Graphics with 96 execution units. The Core 5 320 features Intel Xe3 Graphics with 2 Xe cores. The sockets are incompatible: the i7-1365U uses Intel BGA 1744, while the Core 5 320 uses Intel BGA 1516.

The Verdict

The benchmark data does not point to a single superior chip; it points to two different design philosophies. The Intel Core i7-1365U is the choice for workloads that scale with threads and cache. Its 44.4% lead in Cinebench R23 multicore and 57.4% lead in integer math make it the stronger candidate for rendering, video encoding, or multi-tasking heavy environments. The larger 12 MB L3 cache and dual-channel memory support likely underpin these wins.

The Intel Core 5 320 is the better pick for responsiveness and modern instruction efficiency. Its 15.7% lead in single-thread, 37.3% lead in extended instructions, and 47.3% lead in prime number finding suggest it handles everyday tasks, encryption, and scientific computations with greater agility. The 3 nm process node and higher single-thread clocks (4.60 GHz boost) compensate for fewer cores. The Core 5 320 also wins the passmark multithread test (15450 vs 14045) and physics test (1221 vs 966), indicating it is not simply a single-core specialist.

The overall average benchmark scores are nearly identical: the i7-1365U averages 18177 and the Core 5 320 averages 18023, a negligible difference that places both at the 72nd percentile of all CPUs. The nearest rivals for the i7-1365U include the AMD Ryzen 7 5700U (delta 0%) and Intel Core i7-9700 (delta 0%), while the Core 5 320 sits near the AMD Ryzen 5 1600 (delta 0.2%) and Intel Core 5 120U (delta 0.7%). For users who know their workloads are multi-threaded and integer-intensive, the i7-1365U is the data-backed choice. For anyone seeking a well-rounded, single-thread-fast mobile chip, the Core 5 320 wins more tests and wins them broadly.
