The Verdict

The data presents a clear hierarchy. The Core 5 223PE outperforms the Core 3 305 in every recorded benchmark. The overall average score difference is substantial: 40585 versus 18302, meaning the Core 5 223PE delivers roughly 2.2 times the average benchmark performance. The percentile rankings confirm this separation, with the Core 5 223PE at the 87th percentile and the Core 3 305 at the 72nd percentile.

The Core 5 223PE is the choice for any workload where maximum throughput matters. Its multi-threaded scores are consistently about double those of the Core 3 305. The Cinebench R23 multi-core result alone, 26455 versus 13123, indicates that rendering, compilation, and other heavily threaded tasks will complete in roughly half the time. The integer math advantage of 67.6 percent is particularly relevant for compute-heavy applications that rely on integer operations.

The Core 3 305 remains a functional processor in its own right. The data shows it competes within a narrow band around the 18300 average score mark, trading blows with the Intel Core i3-14100, the Intel Core 5 330, the Intel Core 7 360, and the AMD Ryzen 5 2600E. Its single-threaded PassMark score of 3977 is within reach of the Core 5 223PE's 4219, so for workloads that are strictly single-threaded and do not stress the broader processor pipeline, the gap narrows to 5.7 percent.

The Core 3 305 uses a 15 watt TDP, while the Core 5 223PE uses a 65 watt TDP. The Core 3 305 is a mobile segment part built on a 3 nm process, while the Core 5 223PE is a desktop segment part built on a 10 nm process. These figures contextualize the performance difference: the Core 3 305 achieves its results within a much lower power envelope, while the Core 5 223PE spends more power to deliver significantly higher throughput.

Where Each One Wins

The Core 5 223PE wins every benchmark category in this comparison, so no workload in the recorded data favors the Core 3 305. The closest contest is PassMark single-thread performance, where the Core 5 223PE leads by only 5.7 percent. For tasks that are purely single-threaded and measured by the PassMark single-thread methodology, the two processors are nearly equivalent. The Core 3 305 is not far behind in this narrow slice, but it still trails.

The Core 5 223PE shows its largest advantages in integer math (67.6 percent ahead), data compression (57.6 percent ahead), and random string sorting (50.8 percent ahead). These workloads benefit from the Core 5 223PE's higher core count and thread count. The Core 5 223PE has 8 cores and 16 threads, while the Core 3 305 has 6 cores and 6 threads. The doubling of threads explains the roughly 50 percent advantages seen across most multi-threaded tests.

The Core 5 223PE also holds a clear edge in memory bandwidth. It supports dual-channel memory with 89.6 GB/s of bandwidth, while the Core 3 305 supports single-channel memory with 59.7 GB/s. This bandwidth advantage contributes to the data compression and random string sorting results, both of which are memory-sensitive workloads.

The Core 3 305's closest performance category is prime number finding, where it trails by 27.7 percent. This workload is less parallel-friendly and does not benefit as much from additional cores or memory bandwidth. The Core 3 305's 6 cores at a 4.30 GHz boost clock produce a respectable result here.

For applications that are heavily single-threaded and do not use integer math or memory bandwidth heavily, the Core 3 305 is a viable option. Its 5.7 percent single-thread PassMark deficit means that everyday responsiveness, light productivity, and older software that relies on single-core performance will feel similar on both processors. For anything that scales across cores, the Core 5 223PE is the clear pick.
