All the power of a Ryzen 9 7950X with a TDP of 55W?
AMD revealed Dragon Range, their new family of mobile processors, at CEX earlier this year, and the Ryzen 9 7945HX is one of the more impressive examples. It is based on the Zen 4 chiplet and the 16 cores/32 threads run at a 2.5GHz base, 5.4GHz boost, but is advertised as having a 55W+ TDP, which includes an integrated AMD 610M GPU with RDNA2. To test the effectiveness of this chip, KitGuru tested a 2023 Asus ROG Strix Scar 17 G733PY gaming laptop in a series of CPU tests.
The CPU itself hit less than 100W peak in their tests, but outperformed Intel’s 12th-generation moving parts in many tests. There are even some gaming tests where it outperforms the i9-12900K, although to be fair it has a lot more to do with the RTX 4090 than the Ryzen 9 7945HX. AMD’s claimed power draw is certainly accurate, with a Vcore of 1.2V to 1.3V drawing less than its desktop equivalent, but still manages to deliver similar performance.
If you’re looking for a production laptop that runs software that takes advantage of a powerful CPU, a Ryzen 9 7945HX-based laptop will give you that performance, while consuming relatively more power.
