“Golden Pig Upgrade” just posted a new review for the AMD Ryzen 7 7745 HX processor. While the Ryzen 7000HX series was officially released last month, it seems like there’s uncertainty about the availability of laptops that use the “Dragon Range” series. Although we’ve seen tests for the 12-core Ryzen 9 7845HX and 16-core Ryzen 9 7945HX models, there aren’t many reviews for the 8-core and 6-core models.
A Chinese content creator and reviewer called “Golden Pig Upgrade” has just released the first test of the Ryzen 7 7745HX. It turns out that despite having fewer cores than Intel’s top-of-the-line SKUs, it is just as speedy and, in some cases, even more efficient.
The Ryzen 7 7745HX has a base clock of 3.6 GHz that can boost up to 5.1 GHz. It’s classified as a hybrid between desktop and laptop design because it’s built with a package that’s similar to desktop Raphael, but it’s specifically designed to fit into laptops. Even though it’s a desktop-class CPU, it has an unlocked power limit that allows it to operate within a power range of 45 to 75 watts, and even higher when overclocked.
The reviewer used a Lenovo laptop that had a GeForce RTX 4060 Laptop GPU (140W) and DDR5-5200 memory. While it’s not the most powerful GPU that NVIDIA has to offer, it’s still a pretty capable gaming system.
The reviewer tested the HX CPU using various CPU-related benchmarks such as Cinebench, SuperPI, y-cruncher, and 3DMark. The results showed that despite having significantly fewer cores than Intel’s Core i7-13650HX (14 cores) and Core i7-13700HX (16 cores), the Ryzen 7 7745HX performs almost as well as Intel CPUs in tests like Cinebench or Adobe Premiere Pro. In fact, it is slightly faster in Adobe Lightroom and Photoshop.
Because AMD Ryzen CPU uses less power compared to Intel, the discrete GPU has more power to work with in games, which results in slightly better gaming performance.
The reviewer noted that the AMD CPU can get an additional 3 to 5% performance boost through overclocking with AMD PBO (Precision Boost Overdrive), which can be activated in the BIOS. Besides overclocking, the power efficiency of this CPU is impressive, especially during gaming. When playing at 1080p resolution, the CPU consumes an average of 50.9W, while Intel CPUs consume 46.5W and 79W respectively. Although the Core i7-13650HX has a slight lead when playing at 1440p, it’s only by a few watts.
