AMD Ryzen 9 7845HX “dragon Range CPUs” Power ASUS ROG Laptops to Desktop Performance


Ryzen 9 7845HX “Dragon Range” processors are the most modern mobile central processing units (CPUs) manufactured by AMD. These processors are known as “Dragon Range” since they were developed primarily for the purpose of being put in high-end laptops that are utilized by enthusiasts. When partnered with specific ASUS ROG laptops, enabled with a power limit of up to 130 W, and combined with Precision Boost Overdrive 2, these 12-core/24-thread CPUs give performance that is comparable to that of desktop Ryzen 9 7900X processors. Because of the availability of the Precision Boost Overdrive 2 plugin, this is the consequence (PBO2).

The impressive single-threaded boost frequency of 5.25 GHz, and 4.70 GHz all-core frequency, and a Cinebench R23 multi-threaded score of approximately 25000 points are all results that can be achieved with the 7845HX even when it is operating at its factory default settings and drawing up to 110 W of power. Nevertheless, turning on the Advanced mode on an ASUS ROG laptop raises the power restrictions, allowing the 7845HX to draw up to 130 W of power. This results in temperatures of up to 93 degrees Celsius and significantly improves boost frequency residency. In addition to this, the 7845HX has been “unlocked,” and ASUS ROG laptops come equipped with powerful manual overclocking capabilities that are accessible through the UEFI setup application.

These capabilities are comparable to those that are available on various desktop systems. Manual overclocking in conjunction with PBO2, Curve Optimizer, and Maximum Boost Technology can improve the single-threaded boost to 5.45 GHz, while simultaneously increasing the multi-threaded boost to 5.10 GHz, if the right tweaks are applied. The Cinebench R23 score, which was previously at the stock frequency, has now increased by 14%, reaching a total of 28542 points as a consequence of this change. Its performance is comparable to that of the higher-powered desktop Ryzen 9 7900X processor, which has a higher thermal design power rating (TDP).
