Intel Core Ultra 9 285HX and AMD Ryzen AI 9 HX 375 are both targeting the high-performance laptop segment in 2026, but the two chips serve completely different philosophies. The 285HX pushes multi-core performance with 24 cores and a TDP of up to 160W, while the HX 375 prioritizes a more powerful NPU and significantly better power efficiency. A little-known fact: the Intel Core Ultra 9 285HX does not use Hyper-Threading, so the number of threads equals the number of cores, even though the chip has up to 24 cores. Below is a detailed analysis to help you choose the right machine for your actual needs.
Specifications and Benchmarks: Core Ultra 9 285HX vs. Ryzen AI 9 HX 375
The Intel Core Ultra 9 285HX series belongs to the Arrow Lake-HX architecture, manufactured on a 3 nm process, featuring 24 cores (8P + 16E) and 24 threads, without Hyper-Threading. Boost clock reaches 5,500 MHz, with a base TDP of 55W that can ramp up to 160W when needed. This chip is designed for mobile workstations and high-end gaming laptops requiring heavy multitasking, rendering, and continuous file exporting. The AMD Ryzen AI 9 HX 375 belongs to the Strix Point architecture on a 4 nm process, with 12 cores/24 threads (4 Zen 5 cores and 8 Zen 5c cores), a boost clock of 5,100 MHz, and a flexible TDP ranging from 15W to 54W. Its target segment is high-performance thin-and-light laptops that require long battery life and powerful AI capabilities.
| Specifications | Intel Core Ultra 9 285HX | AMD Ryzen AI 9 HX 375 |
|---|---|---|
| Architecture | Arrow Lake-HX | Strix Point (Zen 5) |
| Cores / Threads | 24 / 24 (No HT) | 12 / 24 |
| Boost Clock | 5,500 MHz | 5,100 MHz |
| TDP (base / turbo) | 55W / 160W | Default 28W (15-54W) |
| NPU TOPS | 13 TOPS | 55 TOPS (XDNA 2) |
| iGPU | Intel Arc Graphics 4-Core | Radeon 890M (RDNA 3.5) |
| Estimated Battery Life | 3-5 hours (heavy workload) | 8-12 hours (actual usage) |
The biggest difference lies in the NPU: the HX 375 features an XDNA 2 NPU reaching 55 TOPS, far surpassing the 13 TOPS of the 285HX. This figure directly determines the ability to run Copilot+ features and on-device AI tasks. The iGPU of the 285HX is a simple integrated Intel Arc Graphics 4-Core, while the HX 375 uses the Radeon 890M RDNA 3.5 with 16 graphics cores, making it significantly more powerful for integrated graphics.
In multi-core benchmark platforms, the 285HX with 24 cores scores very high in the laptop segment, accurately reflecting its advantage in rendering or compiling large source code. The HX 375 with 12 cores/24 threads achieves approximately 15,000 Geekbench multi-core points, staying close in single-core performance thanks to its 5,100 MHz boost clock, but clearly losing in heavy multi-threaded tasks due to having fewer physical cores. This is the core difference between the two design philosophies: the 285HX is for raw power, while the HX 375 is for a balance of AI and battery life.
Multitasking, AI Performance, and Daily Battery Life
Regarding office work and multitasking, the Intel Core Ultra 9 285HX handles things smoothly even if you open 30 Chrome tabs while running Premiere and After Effects simultaneously. The 24-core power is most evident when rendering 4K video, exporting large PSD files, or running virtual machines. A real downside: machines equipped with this chip are typically 2 kg or heavier and generate significant heat when pushed to 160W TDP. If you only need to attend online meetings, write documents, and watch movies, 24 cores are excessive.
Regarding AI features, the HX 375 has a clear advantage with its 55 TOPS NPU, meeting the requirements to run Copilot+ on Windows 11 and on-device AI tasks such as real-time background removal, live translation without internet, or local image generation. The 285HX with 13 TOPS does not meet the Copilot+ threshold (minimum 40 TOPS required), so its AI features rely more heavily on the cloud. If your workflow requires offline AI or high data security, this is a significant difference to consider.
For light gaming, the Radeon 890M iGPU on the HX 375 is significantly stronger than the Intel Arc Graphics 4-Core on the 285HX. Light titles like Valorant or League of Legends can run at 60+ FPS at 1080p resolution with the HX 375’s iGPU. The 285HX usually appears in laptops paired with a discrete GPU, so comparing iGPUs does not truly reflect the actual gaming experience of this machine line. Battery life is where the 285HX clearly loses: a 160W TDP at full load causes the machine to consume battery quickly, lasting only 3 to 5 hours under moderate tasks. The HX 375, with a maximum TDP of 54W, maintains 8 to 12 hours of actual usage depending on the machine configuration.

Frequently Asked Questions (FAQ)
When is the 285HX more powerful than the HX 375, and vice versa?
The 285HX leads significantly in multi-threaded tasks: Blender rendering, 4K video exporting, and running multiple virtual machines simultaneously, thanks to its 24 physical cores. However, in single-core tasks or light workloads, the gap narrows significantly because the HX 375 also has a boost clock of up to 5,100 MHz. The HX 375 wins in integrated graphics (Radeon 890M vs. Intel Arc 4-Core), AI NPU (55 TOPS vs. 13 TOPS), and performance per watt, making it ideal for thin-and-light machines used all day without needing a discrete GPU.
How do these two chips perform in terms of actual battery life and temperature during daily use?
At full load, the 285HX can consume up to 160W, generating significant heat and requiring a bulky cooling system; this is why laptops equipped with this chip are often 2 kg or heavier. Actual battery life is only 3 to 5 hours during work, much lower than thin-and-light laptops. The HX 375, with a TDP of 15W to 54W, allows the machine to stay cooler and provides 8 to 12 hours of battery life depending on the model, making it suitable for those who work away from power outlets.
What can the 55 TOPS NPU of the HX 375 actually do in daily work?
The 55 TOPS NPU meets the requirements to run Copilot+ on Windows 11 (Microsoft requires a minimum of 40 TOPS). In practice, this feature enables Recall, Live Captions for real-time translation without internet, on-device video call background removal, and certain local AI image generation tasks. The 285HX with 13 TOPS does not meet this threshold, so those AI features rely on cloud servers and require an internet connection. For users working in high-security environments or those with unstable internet connections, a powerful NPU is a clear practical advantage.
Approximately how much do laptops equipped with these two chips cost, and where can I find them in Ho Chi Minh City?
Laptops equipped with the 285HX are typically mobile workstations or high-end gaming machines, often paired with a discrete GPU and large batteries, so prices usually start from 40 million VND depending on the GPU and RAM configuration. HX 375 laptops appear in the high-performance thin-and-light segment, with prices typically ranging from 25 to 35 million VND depending on the brand. At Hung Phat in Ho Chi Minh City, you can check out the authentic, fully-warrantied Samsung Galaxy Book4 Ultra or contact us directly to ask about stock and pricing for June 2026; Hung Phat will advise you on the configuration that fits your specific budget.
