Intel Core i3-1315U vs Intel Core i3-1305U

The Intel Core i3-1315U and the Intel Core i3-1305U are energy-efficient 13th generation mobile processors from Intel, based on the Raptor Lake U architecture.

Both were introduced in early 2023 for thin and light laptops, focusing on performance and battery life. Both CPUs are manufactured using the 10 nm process. The Intel Core i3-1315U integrates 2 Performance-cores (P-cores) and 4 Efficiency-cores (E-cores), resulting in 6 cores and 8 threads.

The Intel Core i3-1305U has 1 Performance-core and 4 Efficiency-cores, totaling 5 cores and 6 threads. Both feature 10 MB of Level 3 Cache and the integrated Intel Iris Xe Graphics 64 (Alder Lake) graphics unit with a maximum memory throughput of 83 GB/s. In terms of performance, the Intel Core i3-1315U shows significantly higher performance in some single-core tests.

In multi-core applications, it also demonstrates significantly better performance, reflecting its higher core and thread count. In other single-core and multi-core tests, the processors are comparable. For gaming scenarios, both offer similar entry-level performance with the Intel Iris Xe Graphics 64 (Alder Lake).

The Intel Core i3-1315U might have minimal advantages in CPU-intensive games due to its higher CPU performance, although the integrated graphics unit usually remains the limiting factor. Both U-series processors are optimized for energy efficiency. The Intel Core i3-1315U might require slightly more energy under full load.

A price-performance evaluation is difficult as they are built into complete systems. Generally, the Intel Core i3-1315U offers noticeably higher overall performance for a small additional cost.
