The Intel Core i5-1334U: A Mid-Range Mobile CPU for Thin and Light Laptops

Core i5

The Intel Core i5-1334U 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). The P-cores support Hyper-Threading leading to 12 supported threads when combined with the E-cores. The clock rate ranges from 1.3 to 4.6 GHz on the performance cluster and 0.9 to 3.4 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). 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.


The Core i5-1334U is very similar to the older Core i7-1250U (+100 MHz P-Cores base clock rate). The faster i7 like the i7-1365U models offer only higher clock rates (and a faster iGPU). Compared to the similar i5-1335U, the 1334U only supports slower LPDDR5-5200 (vs 6400 of the faster models) and is therefore slightly slower.


The integrated memory controller supports various memory types up to LPDDR5-5200. 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.

Integrated Graphics

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.

Comparison with other models

The Raptor Lake-U series includes several other models in addition to the Core i5-1334U, each with its own set of features and specifications. Some notable models in this series include the Core i7-1365U, Core i7-1355U, Core i5-1345U, Core i5-1335U, Core i5-1334U, Core i3-1315U, Core i3-1305U, and the Intel Processor U300.


The Intel Core i5-1334U is a powerful and efficient mobile CPU that is ideal for use in thin and light laptops. It offers a good balance of performance and energy efficiency, and is well-suited for a wide range of applications. Its advanced architecture, support for various memory types, and integrated graphics capabilities make it a versatile option for users looking for a high-performing mobile processor.

However, it's worth noting that the 15W TDP may limit sustained performance compared to the higher TDP of the P-series or H-series. Additionally, its support for only "Essentials" vPro management features may also be a limitation for some users or use cases that require advanced management features.

Overall, the Intel Core i5-1334U is a solid choice for users looking for a mid-range mobile CPU that offers a good balance of performance and efficiency, and is well-suited for a wide range of tasks and applications.
