Intel Core Ultra 5 225H vs Intel Core Ultra 5 325: Which is Better for a Laptop?

The Intel Core Ultra 5 325 is newer than the Core Ultra 5 225H, but it is not a direct replacement. The 225H model belongs to the high-performance H-series and features 14 cores, while the 325 model has 8 cores and is designed for more compact and energy-efficient laptops.

The Core Ultra 5 225H performs better under sustained processor load and offers more PCIe lanes. In contrast, the Core Ultra 5 325 features modern Xe3 graphics, a powerful NPU, and a significantly lower power consumption limit.

Key Differences

The Core Ultra 5 225H features four performance cores, eight energy-efficient cores, and two low-power cores. The Core Ultra 5 325 lacks standard E-cores and consists of four P-cores and four LP-E-cores. The 225H also has a higher turbo frequency and 6 MB more cache memory.

The compute tile of the 225H is manufactured using TSMC's N3B process, whereas the 325 uses Intel's 18A. However, the more modern manufacturing process does not compensate for the reduced core count.

CPU Performance

In available benchmarks, the Core Ultra 5 225H often comes out on top, especially under full load.

In single-threaded tests, the 225H holds an advantage of about 5%, while in multi-threaded tests, it’s about 10-15%. This is an expected outcome, as the additional eight E-cores significantly accelerate rendering, compilation, archiving, and video encoding.

The numbers remain approximate since the processors were tested in different laptops. Cooling, memory, and the power limits set by the manufacturer can influence results. In a thin model, the 225H may perform slower than in a larger laptop with a more efficient cooling system.

In browsers, office applications, and video playback, the difference will be minimal. Both processors have four performance cores and handle short daily tasks quickly.

Integrated Graphics

The Core Ultra 5 225H is equipped with Intel Arc 130T featuring seven Xe cores and a frequency of up to 2.2 GHz. The Core Ultra 5 325 uses next-generation Xe3 graphics with four cores and a frequency of up to 2.45 GHz.

In terms of core count, the Arc 130T has the advantage, but comparing different architectures directly is not appropriate. In 3DMark Time Spy, the Xe3 graphics within the Core Ultra 5 325 scores around 2800-3100 points, while the Arc 130T scores about 2400 points. The new architecture can compensate for the reduced configuration and excel in specific graphical tests.

However, a synthetic benchmark alone is not enough for a definitive conclusion. The performance of integrated graphics is highly dependent on memory bandwidth, drivers, and available power. The balance can vary across different games.

Both graphics systems are suitable for:

• undemanding online gaming;
• photo processing;
• hardware-accelerated video;
• operation without a discrete graphics card.

The main limitation of both processors remains the graphics. The four-core Xe3 in the Core Ultra 5 325 should not be confused with the more powerful Arc B370 and B390 used in higher-end Panther Lake versions.

NPU and AI Features

The Core Ultra 5 325 has an NPU with a performance of 47 TOPS compared to 13 TOPS for the Core Ultra 5 225H, an over three-and-a-half times difference.

The 325 model meets a key requirement of Copilot+ PC by having a compatible NPU with a minimum performance of 40 TOPS. However, the ultimate support depends on the laptop's configuration, Windows version, and manufacturer certification.

The NPU inside the 225H is suitable for noise cancellation, camera effects, and certain local algorithms. However, for new Windows features and heavier AI applications, its 13 TOPS are already insufficient. In this comparison, the 325's advantage has practical significance beyond just the specification numbers.

Power Consumption and Cooling

The base power of the processors is nearly identical: 28 W for the 225H and 25 W for the 325. The maximum turbo power difference is more pronounced - 115 W versus 55 W.

The Core Ultra 5 225H can draw more power and maintain high performance longer but requires serious cooling. Therefore, it is better suited for large workstation laptops and models with discrete graphics cards.

The Core Ultra 5 325 has a maximum power cap about 52% lower. It is easier to install in a thin chassis, although the processor itself does not guarantee quiet operation or high battery life. These parameters also depend on the screen, battery, and fan settings.

Memory and Platform Capabilities

Both processors support up to 128 GB of DDR5-6400. The Core Ultra 5 225H also works with LPDDR5X-8400, while the 325 supports LPDDR5X-7467.

In terms of PCIe lanes, the advantage of the older model is even more significant: up to 28 lanes versus 12. The Core Ultra 5 225H is better suited for laptops with discrete graphics cards, multiple SSDs, and additional controllers.

However, the actual set of ports ultimately depends on the laptop manufacturer. Having 28 PCIe lanes does not mean that every model with the 225H will have two drive slots or an extended set of ports.

Which Processor to Choose

The Intel Core Ultra 5 225H is preferable if you need:

• higher multi-threaded performance;
• regular rendering, compilation, or video encoding;
• a laptop with a discrete graphics card;
• multiple storage drives;
• maximum speed when plugged in.

The Intel Core Ultra 5 325 is more rational if you value:

• a thin and light laptop;
• a lower power consumption limit;
• an NPU meeting Copilot+ requirements;
• modern integrated Xe3 graphics;
• everyday use without heavy multi-threaded loads.

Conclusion

The Intel Core Ultra 5 325 is technologically newer but lags behind the Core Ultra 5 225H in pure CPU performance. The difference in multi-threaded tasks typically hovers around 10-15%. The 225H model also offers more cache memory, PCIe lanes, and support for faster LPDDR5X.

The Core Ultra 5 325 excels in other areas: it features Xe3 graphics, a 47 TOPS NPU, and a significantly lower maximum turbo power. This processor is designed for compact laptops, not a replacement for the high-performance H-series.

For heavy workloads and laptops with discrete graphics, the Core Ultra 5 225H is preferable. For thin systems focused on local AI features, the Core Ultra 5 325 is the better choice.
