The i3-1315U: A Balance of Performance and Efficiency in the Raptor Lake-U Series

Core i3

The Intel Core i3-1315U is a mid-range mobile CPU for thin and light laptops that is part of the Raptor Lake-U series. The CPU was announced in early 2023 and offers a total of 6 cores and 8 threads. In this article, we will take a closer look at the performance, features, and specifications of the i3-1315U.


The i3-1315U is a mobile CPU that is designed for thin and light laptops. It offers 2 performance cores (P-cores) and 4 efficient cores (E-cores). The P-cores are based on the Golden Cove architecture and support Hyper-Threading, which allows for 8 supported threads when combined with the E-cores. The E-cores are based on the Gracemont architecture and should have performance similar to old Skylake cores.

The clock rate of the CPU ranges from 1.2 to 4.5 GHz on the performance cluster and from 0.9 to 3.3 GHz on the efficient cluster. This means that the i3-1315U has a 100 MHz higher Boost clock speed than the previous i3-1215U, which should result in slightly better performance. Additionally, the CPU has access to up to 10 MB of L3-cache.


The i3-1315U supports a wide range of memory types, including DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The CPU also includes a Thread Director, which allows the operating system to decide which thread to use on the performance or efficient cores for the best performance.

For AI tasks, the i3-1315U includes GNA 3.0 and DL Boost (via AVX2) to improve performance. The Quick Sync version 8 is also included and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs)

The integrated graphics card is based on the Xe-architecture and offers 64 of the 96 EUs (Execution Units) operating at up to 1.25 GHz. It's based on Alderlake 12th Gen.

Power consumption is rated at 15 W base power (TDP, PL1) and 55 W max. Turbo power (PL2). The SoC is manufactured in a further improved 10nm SuperFin process at Intel, known as Intel 7.


When comparing to other models in the Raptor Lake-U series, the i3-1315U has lower clock speeds and fewer cores than the i5 and i7 models. Additionally, it does not include vPro features. However, it still offers similar performance to old Skylake cores, making it a good option for thin and light laptops.

In addition, the i3-1315U also supports a number of advanced features that are designed to improve performance and efficiency. For example, the CPU includes support for Intel's Speed Optimizer, which allows the system to automatically adjust the power states and performance of the CPU in order to optimize performance and reduce power consumption.

Another important feature of the i3-1315U is its support for Intel's Turbo Boost Technology. This technology allows the CPU to automatically increase its clock speed in order to provide better performance when needed. This means that when the system is running demanding applications or multitasking, the CPU can increase its clock speed to provide better performance, and then lower it again when the system is idle to save power.

The i3-1315U also includes support for Intel's Advanced Vector Extensions 2 (AVX2), which are designed to improve performance in applications that are heavily vectorized. AVX2 allows the CPU to perform more operations in parallel, which means that it can complete tasks more quickly and efficiently.

Finally, the i3-1315U also supports Intel's Hyper-Threading Technology, which allows the CPU to handle more threads at the same time. This means that the system can run multiple applications or perform multiple tasks at the same time more efficiently.

The i3-1315U is an ideal CPU for laptops that require moderate computing power, like office works, internet browsing, streaming, and basic multimedia tasks. It's an option that provides an efficient and balance performance that doesn't break the bank, and has a lower power consumption than most high-end processors. And even though, it's not the top of the line, it's a processor that will fulfill the needs of the majority of the users.
