The first preview of AMD’s Ryzen 9 7945HX “Dragon Range” flagship CPU has been published by NotebookCheck and we see some stunning performance & efficiency numbers.
AMD’s Flagship Ryzen 9 7945HX “Dragon Range” CPU Knocks Out Intel’s 13th Gen Laptop CPUs In Performance & Efficiency
The Ryzen 9 7945HX is going to be AMD’s fastest laptop chip ever made. It will rock the 5nm Zen 4 core architecture and offer a total of 16 cores and 32 threads, the same as the Ryzen 9 7950X CPU from the desktop lineup. These 16 cores will be running at a base frequency of 2.5 GHz and boost up to 5.4 GHz which is highly impressive for a mobility part. The CPU comes with 80 MB of cache & also offers a TDP range of 55-75W+. As further icing on the cake, AMD enables overclocking across its entire Dragon Range lineup which would make for some really powerful laptops.
The folks over at NotebookCheck were able to test the chip out in the ASUS ROG Zephyrus Duo 16 laptop and the results speak for themselves. Starting with the overall performance figures, Ryzen 9 7945HX “Dragon Range” CPU was able to come on par in single-thread and end up faster than the fastest Intel 13th Gen Laptop CPU in multi-threaded benchmarks. While the performance lead has a lot to talk about, what’s even more impressive is the wattage.

AMD Ryzen 9 7945HX “Dragon Range” Laptop Gaming Performance (Credits: Notebookcheck):
Intel’s flagship consumed anywhere from 180-190W and even spiked beyond 200W with average temperatures hovering around 85C. Within a few seconds of operation, the CPU was throttling to sub 3.8 GHz clocks. Meanwhile, AMD’s chip never broke past 120W which was its peak and temps were close to 80C but the chip remained steady with a 4.3-4.4 GHz clock speed.
The benchmark results above obviously do not give us a full picture yet, but the initial results are extremely positive. AMD managed to close the gap in terms of single-core performance with lower power consumption. The new Zen 4 chip is even faster in multi-core benchmarks and still consumes considerably less power at just 120 Watts, which means laptop manufacturer get more headroom for the cooling of the GPU, for example.
The results even compared to the previous-gen ROG Zephyrus Duo 16 which packed an AMD Ryzen 9 6900HX CPU are superb. The older chip did consume 80W power or 33% lower than the 7945HX but the Dragon Range CPU offers more than twice the performance uplift too.

In gaming benchmarks, the AMD Ryzen 9 7945HX CPU was very competitive given its higher chip efficiency and value proposition. The gaming performance mostly depends on the memory config and the power limits of the GPU itself. Having lower temps and power would mean that a certain range of laptops might utilize the available headroom to provide even higher performance in their designs.
This is just one result but it bodes really well for AMD’s Ryzen 7045 “Dragon Range” laptops which are heading out to retail now. Reviews for the Dragon Range line of laptops are expected soon so stay tuned.
