The Intel Core i5-1335U is a mid-range mobile CPU for thin and light laptops based on the Alder Lake architecture (Raptor Lake-U / RPL-U series). It was announced in early 2023 and offers 2 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). This article will provide an overview of the key features and specifications of the Intel Core i5-1335U, as well as its performance and power consumption characteristics.

Performance

The Core i5-1335U has a clock rate that ranges from 1.3 to 4.6 GHz on the performance cluster and 0.9 to 3.4 GHz on the efficient cluster. The P-cores support Hyper-Threading leading to 12 supported threads when combined with the E-cores. The performance of the E-cores should be similar to old Skylake cores. All cores can use up to 12 MB L3 cache. The CPU supports only "Essentials" vPro management features. Compared to the P-series (28W) or H-series (45W), the 15W TDP may limit the sustained performance.

Architecture

The integrated memory controller supports various memory types up to LPDDR5-6400. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU still only supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.

The integrated graphics card is based on the Xe-architecture and offers 80 of the 96 EUs (Execution Units) operating at up to 1.25 GHz.

Power consumption

This Core i5 CPU is rated at a TDP of 15W (base power, PL1) and a maximum turbo power of 55W (PL2). The RPL-U processors are built in a further improved Intel 7 process (10nm SuperFin) that allows higher clock rates.

Additionally, it is worth noting that the i5-1335U is a part of the Raptor Lake-U series of processors. This series includes several other processors that differ in terms of clock speed, core count, and TDP. For example, the Core i7-1365U offers a slightly higher clock rate and has 10/12 cores while the Core i5-1345U has a lower clock rate but similar core count. The Core i3-1315U and i3-1305U have 6/8 and 5/6 cores respectively and are lower end compared to the i5-1335U.

Another important aspect of the i5-1335U is its support for thread director. The Thread Director is a feature of the Alder Lake architecture that allows the operating system to decide which thread to use on the performance or efficient cores for the best performance. This can help improve the overall performance of the system, especially when running multi-threaded applications.

The i5-1335U also has an integrated GPU based on the Xe architecture, and offers 80 of the 96 EUs (Execution Units) operating at up to 1.25 GHz. The GNA 3.0 and DL Boost (via AVX2) support can accelerate AI tasks, quick sync 8 allows hardware-accelerated video encoding and decoding, this is similar to what's in the Rocket Lake CPUs.

Finally, it's worth noting that the i5-1335U has a TDP of 15W and is built using the 10nm SuperFin process which allows for higher clock rates than previous generations. While the 15W TDP may limit the sustained performance, it also makes the i5-1335U more power-efficient and suitable for thin and light laptops.

In conclusion, The Intel Core i5-1335U is a powerful and versatile mobile CPU that is designed for thin and light laptops. With its advanced Alder Lake architecture, integrated Xe GPU, and support for various memory types, it can handle a wide range of tasks and applications. The 15W TDP and thread director feature makes it a great option for power-sensitive and high-performance applications. It's a versatile processor with wide range of options to choose from in the Raptor lake-U series, depending on the specific needs.
