Intel Core Ultra 5 325

Manufacturer: Intel

The Intel Core Ultra 5 325 is a laptop processor built around a hybrid core architecture that combines two distinct clusters of cores for handling varied workloads. It operates under a 25W thermal design power envelope, making it suited for thin-and-light mobile systems where thermal headroom is constrained. The chip supports 64-bit computing and connects to the platform via PCIe 5, reflecting a reasonably current platform foundation for a mobile part.

On the performance side, the processor runs base clocks of 2.1 GHz and 1.6 GHz across its two core groups, with a turbo clock speed reaching 4.5 GHz through Turbo Boost version 2, and it carries 12 MB of L3 cache alongside 8 threads total. Memory support extends to DDR5 at up to 7467 MHz across two channels, with a maximum capacity of 128 GB. The integrated graphics unit peaks at 2300 MHz and is compatible with DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, while supporting up to four simultaneous displays. Instruction set support includes AVX2, FMA3, AES, and SSE 4.1/4.2 among others, and the chip includes an NX bit for hardware-level memory protection.

Pros
  • Supports DDR5 memory at speeds up to 7467 MHz across two channels, enabling fast data throughput for a laptop processor
  • Can address up to 128 GB of RAM, offering substantial memory capacity for a mobile chip
  • Turbo clock speed reaches 4.5 GHz via Turbo Boost, providing a meaningful frequency uplift over base clocks when needed
  • Integrated graphics support up to four simultaneous displays with DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3 compatibility
  • PCIe 5 support ensures the platform can handle current-generation high-speed peripherals and storage
  • Includes NX bit for hardware-level memory protection against certain exploit-based attacks
Cons
  • Only 8 threads total across all cores, which may limit throughput in heavily multi-threaded workloads
  • L3 cache is limited to 12 MB, which can become a bottleneck for cache-sensitive applications
  • big.LITTLE configuration splits cores between 2.1 GHz and 1.6 GHz clusters, meaning half the cores run at a relatively low base frequency
  • Turbo Boost version 2 is an older iteration of the boost technology
  • 25W TDP, while typical for thin laptops, leaves limited sustained performance headroom under prolonged loads
Who is this for?

This processor is a solid fit for users who need a capable laptop chip for everyday productivity, light creative tasks, and general computing within a power-efficient 25W thermal envelope. The DDR5 support at up to 7467 MHz and a maximum of 128 GB RAM make it well-suited for workflows that benefit from fast memory throughput, such as data handling, multitasking across many browser tabs, or running moderately demanding applications. Users who need multi-display setups of up to four screens from an integrated graphics solution will also find this chip accommodating, as will those who rely on AES hardware acceleration or AVX2 for relevant compute tasks.

Who is this NOT for?

Users with demanding heavily multi-threaded workloads — such as video encoding, 3D rendering, or large-scale compilation tasks — may find the 8-thread count and modest base frequencies limiting under sustained loads. The integrated graphics, while feature-complete in terms of API support, are not suited for GPU-intensive tasks like gaming at meaningful settings or real-time creative rendering, where a dedicated graphics solution would be necessary. Similarly, professionals whose workflows are sensitive to cache performance may find the 12 MB L3 cache insufficient, and the relatively older Turbo Boost version 2 means the chip lacks more advanced frequency scaling found in newer boost implementations.

supported displays 4
OpenGL version 4.6
OpenCL version 3

The integrated graphics unit reaches a turbo frequency of 2300 MHz and supports up to four displays simultaneously. It is compatible with DirectX 12 Ultimate, along with OpenGL 4.6 and OpenCL 3, covering a broad range of graphics and compute workloads handled directly by the integrated solution.

Memory:

RAM speed (max) 7467 MHz
DDR memory version 5
memory channels 2
maximum memory amount 128GB

The processor supports DDR5 memory across two channels, with a maximum RAM speed of 7467 MHz. It can address up to 128 GB of total memory, providing ample headroom for memory-intensive workloads within a dual-channel configuration.

Features:

instruction sets MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, SSE 4.2
Has NX bit ✓

The processor supports a range of instruction sets including AVX2, FMA3, and AES, alongside MMX, F16C, AVX, SSE 4.1, and SSE 4.2, enabling hardware-level acceleration for a variety of computational and cryptographic tasks. It also includes an NX bit, which provides hardware-enforced memory protection to help prevent certain classes of malicious code execution.

Final Verdict

The Intel Core Ultra 5 325 is a laptop processor that strikes a reasonable balance between power efficiency and capability, anchored by its DDR5 support at speeds up to 7467 MHz and a flexible integrated graphics unit that handles up to four displays with modern API compatibility. Its 25W TDP keeps it well within the thermal constraints of thin mobile systems, and the turbo ceiling of 4.5 GHz provides adequate burst performance for everyday and moderately demanding tasks. Where it shows its limits is in sustained multi-threaded scenarios and GPU-intensive workloads, where its 8-thread configuration and integrated graphics reach their practical ceiling relatively quickly. For users whose priorities align with efficient everyday computing, capable memory bandwidth, and a feature-complete integrated graphics solution, the Core Ultra 5 325 represents a well-rounded mobile chip — provided expectations are set appropriately around its scope.
