AMD Ryzen 9 7845HX 12-Core Dragon Range CPU On Par With Desktop Ryzen 9 7900X At 130W Using PBO

New AMD Ryzen 9 7845HX Dragon Range CPU benchmarks show some big performance figures when using PBO in an extremely efficient design.

In terms of specifications, the AMD Ryzen 9 7845HX CPU features 12 cores and 24 threads. The CPU has a base clock of 3.0 GHz and a boost clock of 5.2 GHz while adopting 76 MB of total cache (64 L3 + 12 L2). The CPU has a 55-75W+ TDP range and features an integrated Radeon 610M GPU with two compute units clocked at 2.2 GHz. The CPU features a fully unlocked (Precision Boost Overdrive & Curve Optimizer) design and also supports EXPO memory profiles on the laptop platform.

A user over at Chiphell Forums has shared benchmarks of the latest ASUS ROG laptop rocking an AMD Ryzen 9 7845HX Dragon Range CPU and an NVIDIA GeForce RTX 4060 GPU. It is reported the chip consumes around 110W of power by default. In its default state, the chip runs up to 5.25 GHz single-core and 4.7 GHz multi-core boost clocks while offering a multi-threaded score of around 25 thousand points. Using the Enhanced mode offered by ASUS ROG laptops, the CPU can hit up to 93 degrees with 130W power for minor performance increases.

The real deal seems to be manual overclocking using PBO2. The user states that the ASUS BIOS has the option to allow similar overclocking to desktops with PBO2, Curve Optimizer and also supports Maximum Frequency Boost technology. With the manual overclock applied, the CPU achieved core frequencies of up to 5.45 GHz on a single-core and around 5.1 GHz for multi-core workloads. AMD's Ryzen 9 7845HX achieved a score of 28542 points in the multi-core and 1960 points in single-core tests which is a 14% improvement over the default score.

The overclocked score puts the chip on par with Intel's high-end Core i9 Raptor Lake-HX chips that feature up to 24 cores and 32 threads. Furthermore, the chip still consumed under 130W of power (127W to be precise). This is around the same performance you get from a Ryzen 9 7900X Desktop CPU but the difference is that the AM5 chip consumes close to 200W by default.

The same is the case with Intel's high-end chips. It is going to be very easy for the Ryzen 9 7945HX 16-core Dragon Range CPU to break easily past the 30K barrier in Cinebench R23 when overclocked considering how well the 7845HX 12-core chip did.

AMD Dragon Range CPUs are also optimized for idle power with the chips consuming around 13W in the overclocked (PBO2) state and just under 10W when running in their default state. Overall, the AMD Dragon Range lineup has shown to offer fantastic CPU performance and efficiency with its Zen 4 core architecture. AMD has already announced the official availability of its first high-end laptops as we reported here.
