Intel Core Ultra 5 225H: Is It Worth Paying Extra for the 235H?

The Core Ultra 5 225H is priced lower than the 235H model, but its processor performance is nearly identical. It features the same configuration of 14 cores, with differences mainly in clock speeds and integrated graphics. Therefore, the decision between such laptops is often determined by factors other than the numbers in the processor name, such as price, cooling, and memory configuration.

14 Cores and 14 Threads

The processor uses three types of cores:

• 4 performance P-cores;
• 8 efficient E-cores;
• 2 low-power LP E-cores.

The maximum frequency of the P-cores reaches 4.9 GHz, while the E-cores can go up to 4.3 GHz. The third-level cache is 18 MB. The base power is 28 W, with a maximum turbo limit of 115 W.

Each core handles one thread: the Arrow Lake-H mobile processors do not utilize Hyper-Threading technology. In terms of thread count, this is lower than the Core Ultra 5 125H, which supported 18 threads. However, the number of threads alone does not define performance: the 225H benefits from newer cores and significantly higher frequencies for the E-cores.

In web browsing and office applications, the advantage over the U-series is nearly negligible, but in prolonged multi-threaded tasks, the 225H is significantly faster.

225H and 225U - Processors of Different Classes

The Core Ultra 5 225U features two P-cores, a base power of 15 W, and weaker integrated graphics. The 225H has four P-cores, a higher power limit, and the Arc 130T.

In browsing, office applications, and video playback, the difference is usually minor. The advantage of the 225H is more noticeable in resource-intensive tasks:

• photo processing;
• video editing and exporting;
• compiling large projects;
• working with virtual machines.

The performance of two laptops with the same processor can vary significantly. In thinner chassis, power limits are typically lower, while more effective cooling allows the processor to maintain higher frequencies for longer.

Arc 130T is Suitable for Gaming, but Does Not Replace a Discrete Graphics Card

The Core Ultra 5 225H comes with Intel Arc 130T, featuring seven Xe-cores and a frequency of up to 2.2 GHz. It supports hardware AV1 processing and accelerates playback, editing, and exporting video in compatible applications.

The Arc 130T is designed for esports, moderate modern games, and demanding older releases on lower settings. In new resource-intensive games, you will need to reduce resolution and image quality, as well as utilize XeSS or other scaling options.

The performance of the Arc 130T is especially influenced by memory bandwidth. A single DDR5 module can significantly reduce gaming speed. Therefore, a 2 × 8 GB configuration may be faster than a single 16 GB module with the same total capacity.

The Core Ultra 5 225H supports DDR5-6400 and LPDDR5X-8400. In laptops without a discrete graphics card, it is crucial to check the memory configuration carefully.

83 TOPS Does Not Mean a Powerful NPU

Intel specifies a total AI block performance of up to 83 TOPS. Of these, 63 TOPS are provided by the integrated graphics, and the NPU only delivers 13 TOPS.

The NPU is intended for background tasks such as image blurring, gaze correction, and noise reduction, reducing the load on the CPU and GPU. However, for Copilot+ PC, this is insufficient: Microsoft requires at least 40 TOPS from the neuroprocessor.

In terms of NPU capabilities, the Core Ultra 5 225H significantly lags behind platforms designed for Copilot+ PC. The chip's strengths lie in its high CPU performance and the Arc 130T, not the neural block.

Core Ultra 5 225H vs. 235H

Both processors utilize the same core configuration and differ primarily in clock speeds. Their CPU configuration, cache size, and base power are identical.

The differences focus on clock speeds and graphics:

With identical power limits, the gap in CPU tasks is small: the core configuration is the same, while the maximum frequencies differ by 100 MHz.

The more noticeable advantage of the 235H is related to the Arc 140T graphics, which has eight Xe-cores instead of seven. This is more significant for games relying on integrated graphics than the slight increase in CPU frequency.

If the model with the 235H is not much more expensive and is comparable in screen, memory, and cooling system, the extra payment makes sense. With a noticeable price difference, it is more beneficial to choose the Core Ultra 5 225H. Better cooling, dual-channel memory, or a larger SSD are more advantageous than a minor frequency boost.

Who Should Consider a Laptop with Core Ultra 5 225H

Such a laptop would be suitable for programming, photo editing, video editing, and gaming on integrated graphics.

When choosing, the following factors are especially important:

• dual-channel RAM;
• effective cooling system;
• ability to replace or expand memory;
• screen with accurate color reproduction;
• a second M.2 slot for a drive.

If minimal thickness and battery life are priorities, processors from the U series or Core Ultra 200V are more appropriate. For regular 3D rendering, complex video editing, and new demanding games, a laptop with a discrete graphics card is necessary.

Conclusion

The Intel Core Ultra 5 225H is the entry-level model of the Arrow Lake-H series without significant cuts to the processor features. Its CPU configuration is the same as that of the 235H, but its frequencies are 100 MHz lower, and the Arc 130T has seven Xe-cores instead of eight.

Final performance heavily depends on the power limits, cooling, and memory of the specific laptop. Poor cooling or single-channel memory can negate the advantage of the 235H.

In comparable cases concerning chassis and memory, it makes sense to choose the Core Ultra 5 235H only with a small premium or for the sake of stronger integrated graphics.
