The Intel Core i5-1345U is a mid-range mobile CPU designed for thin and light laptops. It is based on the Alder Lake architecture (Raptor Lake-U/RPL-U series) and was announced in early 2023.

Performance Cores:

The CPU features 2 performance cores (P-cores), which are based on the Golden Cove architecture. These cores support Hyper-Threading, allowing for 12 supported threads when combined with the 8 efficient cores (E-cores) based on Gracemont architecture. The clock rate of the P-cores ranges from 1.6 to 4.7 GHz and the clock rate of the E-cores ranges from 1.2 to 3.5 GHz. The E-cores are similar in performance to the old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 12 MB L3 cache.

Architecture:

The integrated memory controller supports various memory types up to LPDDR5-6400. The Thread Director, which is 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 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:

The Core i5-1345U is rated at a TDP of 15W (base power, PL1) and a maximum turbo power of 55W (PL2). It is built in a further improved Intel 7 process (10nm SuperFin) that allows higher clock rates.

Other Features:

The CPU supports "Enterprise" vPro management features. Compared to the P-series (28W) or H-series (45W), the 15W TDP may limit the sustained performance. It also supports 64 bit support and x86 architecture

Comparison to Other Models

The CPU is similar to the older Core i7-1255U (+100 MHz P-Cores base clock rate). Faster i7 models like the i7-1365U models offer only higher clock rates (and a faster iGPU)

Performance:

The Core i5-1345U is a powerful CPU that is capable of delivering high performance for a wide range of tasks. The P-cores, with their high clock speeds and Hyper-Threading support, are well suited for demanding workloads such as gaming, video editing, and software development. The E-cores, with their lower clock speeds and more efficient architecture, are ideal for less demanding tasks such as web browsing, email, and word processing. Together, the P-cores and E-cores work together to provide a balanced performance that is well suited for both personal and professional use.

Architecture:

The Alder Lake architecture used in the Core i5-1345U is a significant improvement over previous generations of Intel CPUs. This architecture features a new design that allows for more cores and more efficient use of those cores. The Thread Director, which is in hardware, allows the operating system to decide which threads to use on the P-cores and E-cores for the best performance. This feature helps to ensure that the CPU is always running at optimal performance levels, regardless of the task at hand.

The integrated memory controller in the Core i5-1345U supports various memory types up to LPDDR5-6400, providing fast and efficient access to memory. Additionally, the CPU includes advanced features such as GNA 3.0 and DL Boost, which are specifically designed to accelerate AI and deep learning workloads.

Power Consumption:

The Core i5-1345U is rated at a TDP of 15W (base power, PL1) and a maximum turbo power of 55W (PL2). This means that the CPU can consume up to 55W of power when it is running at its highest clock speeds. While this may seem like a high power consumption, it is important to note that this is typical for a CPU of this performance level. Additionally, The RPL-U processors are built in a further improved Intel 7 process (10nm SuperFin) that allows higher clock rates which helps to improve performance while maintaining a low power consumption.

Conclusion:

Overall, the Intel Core i5-1345U is a powerful and versatile CPU that is well suited for a wide range of applications. Its Alder Lake architecture and advanced features such as GNA 3.0 and DL Boost make it an excellent choice for those who require high performance and power efficiency. Additionally, with its integrated memory controller, support for various memory types, and advanced thread management capabilities, the Core i5-1345U is an excellent choice for both personal and professional use.
