Ryzen AI 9 HX 370 vs Ryzen 9 8945HS: Choosing the Right Mobile Powerhouse

The landscape of high-performance laptops has shifted dramatically toward local artificial intelligence and hybrid computing architectures. As we navigate the current market, two processors often stand at the center of the debate for power users: the AMD Ryzen AI 9 HX 370 and the AMD Ryzen 9 8945HS. While both carry the "Ryzen 9" pedigree, they represent two different eras of AMD's mobile strategy. The former is a cornerstone of the Strix Point "Zen 5" generation, while the latter is the refined peak of the Hawk Point "Zen 4" series. Choosing between them requires more than a glance at clock speeds; it demands an understanding of how NPU throughput, core counts, and integrated graphics have evolved.

The Architectural Leap: Zen 5 vs. Zen 4

The most fundamental difference between these two chips is the underlying architecture. The Ryzen 9 8945HS utilizes the Zen 4 architecture, a highly successful and efficient design that focused on high clock speeds and consistent performance across all cores. Every core in the 8945HS is a full-performance core, designed to handle identical instruction sets with the same cache access speeds.

In contrast, the Ryzen AI 9 HX 370 introduces the Zen 5 and Zen 5c hybrid architecture. This is a significant pivot for AMD. By combining high-performance Zen 4 cores with more area-efficient Zen 5c cores, AMD has managed to increase the total core count to 12 without exponentially increasing the chip's physical footprint or power draw. Zen 5 brings an IPC (Instructions Per Clock) improvement of approximately 16% over its predecessor. This means that even at the same clock speed, the HX 370 can execute more tasks per second than the 8945HS. The inclusion of Zen 5c cores allows the system to offload background tasks to more efficient silicon, reserving the high-performance Zen 5 cores for demanding foreground applications like gaming or video rendering.

Core Counts and Multitasking Dynamics

When looking at the numbers, the gap is clear. The Ryzen 9 8945HS features a traditional 8-core, 16-thread configuration. For years, this was the gold standard for premium thin-and-light performance laptops. It provides ample headroom for heavy multitasking, such as running multiple browser tabs alongside office suites and creative software.

However, the Ryzen AI 9 HX 370 ups the ante with 12 cores and 24 threads. This 50% increase in thread count is a game-changer for professional workloads. In multi-threaded benchmarks like Cinebench R23 or the newer 2024 versions, the HX 370 consistently outperforms the 8945HS by margins ranging from 25% to 35%. This isn't just about benchmark scores; it translates to faster video exports in Premiere Pro, quicker compile times for software developers, and smoother performance when running virtual machines. The ability of the HX 370 to juggle two dozen simultaneous threads makes it the superior choice for anyone whose workflow involves heavy computational parallelization.

The Integrated Graphics Revolution: Radeon 890M vs. 780M

Integrated graphics performance has reached a point where discrete GPUs are no longer a strict necessity for casual gaming or light creative work. The Ryzen 9 8945HS comes equipped with the Radeon 780M, an iGPU based on the RDNA 3 architecture with 12 Compute Units (CUs). Even today, the 780M is a formidable performer, capable of running most modern AAA titles at 1080p with low-to-medium settings.

The Ryzen AI 9 HX 370, however, debuts the Radeon 890M. This iGPU is built on the refined RDNA 3.5 architecture and boosts the CU count to 16—a 33% increase. Furthermore, the maximum clock speed has been nudged higher. In practical gaming scenarios, the Radeon 890M provides a significant frame rate boost, often allowing users to move from "Low" to "Medium" or "High" settings at 1080p while maintaining a smooth 60 FPS. For handheld gaming enthusiasts or those using ultra-portable laptops without a dedicated graphics card, the transition from the 780M to the 890M represents one of the biggest generational leaps in integrated graphics history. It bridges the gap between "playable" and "enjoyable" in demanding titles like Cyberpunk 2077 or the latest open-world RPGs.

AI Performance and the 50 TOPS Threshold

As we enter the era of the AI PC, the Neural Processing Unit (NPU) has become as vital as the CPU and GPU. The "AI" in the Ryzen AI 9 HX 370's name isn't just marketing—it signifies a massive upgrade in local AI processing power. The HX 370 features the XDNA 2 NPU, which delivers up to 50 TOPS (Trillion Operations Per Second) of AI performance.

This is a stark contrast to the Ryzen 9 8945HS, which features the first-generation XDNA NPU capable of 16 TOPS. While 16 TOPS was sufficient for basic tasks like background blur in video calls or eye-contact correction, it falls short of the requirements for Microsoft’s Copilot+ PC certification. The 50 TOPS provided by the HX 370 allows for much more sophisticated local AI workloads. This includes running large language models (LLMs) locally with higher tokens-per-second, real-time AI image generation, and more advanced features in creative suites that rely on neural networks for object tracking and masking. If you plan on keeping your laptop for the next three to four years, the 50 TOPS NPU in the HX 370 provides a level of future-proofing that the 8945HS simply cannot match.

Power Efficiency and Thermal Management

Both processors are designed with a configurable TDP (cTDP) ranging from 15W to 54W. However, their efficiency curves differ due to the architectural changes. The 8945HS is manufactured on a 4nm process and is incredibly mature. It runs cool in most chassis designs and offers excellent battery life during standard office tasks. Because all its cores are Zen 4, its power delivery is predictable.

The Ryzen AI 9 HX 370 also uses a 4nm process but benefits from the Zen 5c cores. These "compact" cores are designed to operate at lower voltages and frequencies while maintaining high efficiency. In light-duty tasks—streaming video, browsing the web, or document editing—the HX 370 can often achieve better battery life than the 8945HS by aggressively parking the power-hungry Zen 5 cores. However, when pushed to its 54W limit, the HX 370 generates more heat due to the higher core density. Users should ensure that the laptop chassis housing the HX 370 has a robust cooling solution to prevent thermal throttling during sustained workloads.

Memory Support and Data Throughput

Data bottlenecking is a concern in modern systems. The Ryzen 9 8945HS typically supports DDR5-5600 or LPDDR5x-7500 memory. This provides plenty of bandwidth for most applications. However, the Ryzen AI 9 HX 370 pushes this further, with support for LPDDR5x-8000.

This higher memory frequency is particularly beneficial for the integrated Radeon 890M GPU, which relies on system RAM for its video memory. The extra bandwidth provided by the HX 370's memory controller allows the GPU to access data faster, reducing micro-stuttering in games and speeding up texture loading. Additionally, the HX 370 features a larger L3 cache (24MB vs 16MB), which helps reduce latency in gaming and complex calculations by keeping more data close to the processor cores.

Practical Benchmarking Trends

While individual results vary based on laptop cooling and power limits, clear trends have emerged. In single-core performance, the Ryzen AI 9 HX 370 generally holds a 10-15% lead over the 8945HS. This is felt in the snappiness of the operating system and the speed of launching applications.

In multi-core tests like Cinebench, the lead expands to nearly 30% because of the 12-core vs 8-core disparity. In graphics-heavy benchmarks like 3DMark Time Spy, the Radeon 890M consistently scores 20-25% higher than the Radeon 780M. Perhaps most importantly, in AI-specific benchmarks like Procyon AI Inference, the HX 370 can be two to three times faster than the 8945HS when utilizing the NPU. This data suggests that the HX 370 isn't just a minor refresh; it is a comprehensive upgrade across every major subsystem.
