The new AMD Ryzen 9 7845HX Dragon Range CPU benchmarks show some significant performance figures when using PBO in an extremely efficient design. The AMD Ryzen 9 7845HX CPU has 12 cores and 24 threads in terms of specifications. The CPU has a base clock of 3.0 GHz and a boost clock of 5.2 GHz, with a total cache of 76 MB (64 L3 + 12 L2). The CPU has a TDP of 55-75W+ and an integrated Radeon 610M GPU with two compute units clocked at 2.2 GHz. On the laptop platform, the CPU has a fully unlocked (Precision Boost Overdrive & Curve Optimizer) design and supports EXPO memory profiles.
Benchmarks of the latest ASUS ROG laptop with an AMD Ryzen 9 7845HX Dragon Range CPU and an NVIDIA GeForce RTX 4060 GPU have been shared by a user on Chiphell Forums. The chip is said to consume around 110W of power by default. The chip can run up to 5.25 GHz single-core and 4.7 GHz multi-core boost clocks in its default state, with a multi-threaded score of around 25 thousand points. Using ASUS ROG laptops’ Enhanced mode, the CPU can reach up to 93 degrees Celsius with 130W of power for minor performance boosts.
Manual overclocking with PBO2 appears to be the real deal. According to the user, the ASUS BIOS allows for similar overclocking to desktops with PBO2, Curve Optimizer, and Maximum Frequency Boost technology. With the manual overclock enabled, the CPU achieved single-core core frequencies of up to 5.45 GHz and multi-core workloads of around 5.1 GHz.
AMD’s Ryzen 9 7845HX scored 28542 points in multi-core tests and 1960 points in single-core tests, representing a 14% improvement over the default score.
The chip’s overclocked score puts it on par with Intel’s high-end Core i9 Raptor Lake-HX processors, which have up to 24 cores and 32 threads. Furthermore, the chip consumed less than 130W of power (127W to be precise). This is comparable to the performance of a Ryzen 9 7900X Desktop CPU, but the AM5 chip consumes close to 200W by default.
The same is true for Intel’s high-end chips. Given how well the 7845HX 12-core chip performed, the Ryzen 9 7945HX 16-core Dragon Range CPU will easily break through the 30K barrier in Cinebench R23 when overclocked.
AMD Dragon Range CPUs are also optimised for idle power, consuming around 13W in overclocked (PBO2) mode and just under 10W in their default mode. Overall, the AMD Dragon Range lineup has demonstrated excellent CPU performance and efficiency thanks to its Zen 4 core architecture.
