[Comparison] AMD Ryzen AI 9 HX 370 vs Ryzen 9 8945HS – The New Zen 5 is 5% better for Everyday Tasks
How much did AMD improve its CPUs with the jump from Zen 4 to Zen 5? Today we’re figuring that out, by comparing the brand new AMD Ryzen AI 9 HX 370 in the ASUS Zenbook S 16 to the Ryzen 9 8945HS. The new architecture is available in the Ryzen AI 300-series, which are all AI-powered processors, with the CPU, iGPU, and an NPU, so AMD can cover the requirements for the new Copilot+ PCs.
There’s a drastic change in terms of the cores and threads, as well as to the cores themselves. Power limits are as flexible as they’ve ever been now too, but more on that when we get to the specs.

Specs table
Looking at the specs, we see the Zen 5 CPU bring 4 more cores and 8 extra threads. The clock speeds on the Ryzen 9 8945HS are higher, with the base and the boost speeds, all thanks to the more consistent TDP, which hovers between 35W and 45W. However, with a more powerful laptop and cooling setup, the CPU will easily go above these values and reach 5.00 GHz with no problem. The AI chip (NPU) of the Ryzen AI 9 is a lot more powerful with 50 TOPS vs 16 TOPS (Trillion Operations Per Second), allowing you to utilize and develop local AI models.

CPU benchmarks
In Cinebench 2024, the result is 5% in favor of the Ryzen AI 9 HX 370. The Geekbench 6 results are: 1% advantage in Multi-core for AI 9 and 5% advantage in Single-core performance.
The Single-core test represent everyday tasks like responsiveness in the OS, while Multi-core is important for Heavy work applications.
Single-core performance ensures smooth operation and responsiveness in operating systems, providing a better user experience.
Results are from the Geekbench 6 Single-Core test (higher is better)
Multi-core performance is essential for handling complex and demanding tasks, such as Video editing, CAD, and Scientific simulations.
Results are from the Geekbench 6 Multi-Core test (higher is better)
Here, we evaluate the CPU's performance using a real-world 3D rendering task, assessing its ability to handle complex computations and rendering workloads efficiently.
Results are from the Cinebench 2024 Multi-Core test (higher is better)
