AMD Ryzen AI 9 HX 470 vs Intel Core Ultra 9 285H: Comparison in Real Laptops

Both processors are designed for high-end, performance laptops, but they behave differently. The Ryzen AI 9 HX 470 focuses on sustained multi-threaded workloads and a powerful NPU, while the Core Ultra 9 285H can deliver high performance under generous power limits. Therefore, it is necessary to compare not only the chips but also the specific laptops.

Key Differences

The Ryzen AI 9 HX 470 has four full-size Zen 5 cores and eight compact Zen 5c cores. Thanks to SMT, the processor handles 24 threads.

The Core Ultra 9 285H has a larger number of physical cores but operates without Hyper-Threading. Its advantage is a higher peak frequency and the ability to significantly increase power in short bursts.

Processor Performance

There is no single winner between this pair in all tests.

In Cinebench R23, the Ryzen confidently leads in multi-threaded mode. Its 24 threads perform better in prolonged rendering, video encoding, and other tasks that can fully utilize all cores over an extended time.

In Geekbench, the situation is reversed. The Core Ultra 9 285H is approximately 11% faster in the multi-threaded test due to the combination of fast P-cores, a greater number of physical cores, and high turbo frequencies.

In terms of single-thread performance, the difference is within 2%. This difference would be imperceptible in browsers, office applications, and most everyday tasks.

Results in Specific Devices

It's impossible to predict a laptop's performance based solely on the processor model. This is especially true for the Core Ultra 9 285H.

Cinebench R23 Multi Core

The devices with Ryzen fall within a comparatively narrow range. Even the compact GEEKOM A9 Max lags behind the Lenovo Legion 7 by about 6%.

For the Core Ultra 9 285H, the variance is much wider. In one laptop, the processor may approach Ryzen's results, while in another, it could lose several thousand points due to power and cooling limitations.

This does not inherently make Intel weaker, but it complicates choosing the right device. The Core Ultra 9 285H should be evaluated alongside a specific laptop model rather than separately.

Where These Processors Are Found

The Ryzen AI 9 HX 470 is installed in various devices:

• ASUS ExpertBook P5 G2 - a work laptop without discrete graphics;
• Lenovo Legion 7 16AGP11 - a powerful model with GeForce RTX 5060 or RTX 5070;
• GEEKOM A9 Max - a compact mini-PC.

The Core Ultra 9 285H can also be found in several classes of devices:

• ASUS Zenbook Duo OLED - a premium laptop with dual displays;
• Lenovo Yoga Pro 7 - a compact high-performance model;
• ASUS ROG Zephyrus G16 - a thin gaming laptop.

Such a range of form factors explains the noticeable difference in results. The same processor can operate under vastly different power limits.

Radeon 890M vs Intel Arc 140T

The Arc 140T often performs better in 3DMark and individual compute tests. Meanwhile, the Radeon 890M frequently looks better in real gaming scenarios.

The outcome depends on the specific project, driver, memory speed, and power available to the processor. Therefore, there is no outright winner here.

For a laptop without a discrete graphics card, the Radeon 890M appears to be a more consistent gaming solution. The Arc 140T is more interesting for tasks that utilize Intel Quick Sync, OpenVINO, and other Intel platform optimizations.

In models with GeForce RTX 5060, RTX 5070, or more powerful graphics cards, the difference between the integrated GPUs has minimal impact on gaming performance.

NPU and Local AI Features

In terms of the power of the individual neural accelerator, AMD wins by a wide margin: up to 55 TOPS compared to 13 TOPS for Intel.

This difference is crucial for applications that truly utilize the NPU. These include local image processing, noise reduction, video conferencing effects, and some generative functions.

However, 55 TOPS does not imply a fourfold speed-up for any AI application. The actual result depends on software support. Purchasing the HX 470 solely for the NPU should be based on specific use scenarios rather than just a number in the specifications.

Power Consumption and Cooling

The Ryzen AI 9 HX 470 is designed for a range up to 54 W. The Core Ultra 9 285H can briefly increase power consumption to 115 W.

Intel does not operate at peak levels continuously, but to fully unleash the processor, significant cooling headroom is required. In a thin chassis, manufacturers might throttle the processor, resulting in significantly lower-than-expected performance.

The Ryzen is easier to maintain within the 40-54 W range. As a result, it often provides stable performance under sustained workloads without resorting to heavy cooling, like that found in gaming HX models.

Autonomy cannot be compared based solely on processor specifications. It is more influenced by factors such as display, battery, discrete graphics card, and the particular settings of the laptop.

Which Processor to Choose

Ryzen AI 9 HX 470 is better suited for:

• Extended rendering and encoding;
• Compilation and multi-threaded computing;
• Work laptops without discrete graphics;
• Local AI functions utilizing the NPU;
• Systems with power constraints up to 54 W.

Core Ultra 9 285H is better suited for:

• Software utilizing Intel Quick Sync;
• Tasks optimized for OpenVINO;
• Laptops with Thunderbolt 4 and PCIe 5.0;
• Models with efficient cooling;
• Short mixed workloads with active turbo mode.

Conclusion

AMD Ryzen AI 9 HX 470 excels in prolonged multi-threaded workloads and offers a significantly more powerful NPU. It often shows stable performance under moderate power consumption and is better suited for rendering, development, and local AI tasks.

Intel Core Ultra 9 285H can outperform in Geekbench and other short mixed workloads. It also provides advantages from the Intel platform, including Quick Sync, Thunderbolt 4, and PCIe 5.0.

The main difference lies in the dependency on the specific laptop. The Ryzen appears more predictable, while the Core Ultra 9 285H should be chosen in a verified model with effective cooling and appropriate power limits.
