AMD Dragon Range with 8 cores as fast as 14-16 core Intel 13th Gen Core HX series

A new review of the AMD Ryzen 7 7745 HX processor has been posted by Golden Pig Upgrade

Officially, AMD Ryzen 7000HX series were already released last month, but the availability of laptops powered by the “Dragon Range” series is questionable. We have already seen tests featuring 12-core Ryzen 9 7845HX and 16-core Ryzen 9 7945HX models, but for some reason there are hardly any reviews of the 8-core and 6-core models.

The first test of Ryzen 7 7745HX has now been published by a Chinese content creator and reviewer, “Golden Pig Upgrade”. As shown, despite featuring fewer cores than Intel flagship SKUs, it is just as fast and even has some advantages in terms of efficiency.

The Ryzen 7 7745HX has a base clock of 3.6 GHz and boost up to 5.1 GHz. This processor is considered a hybrid between desktop and laptop design because it uses a similar package to desktop Raphael, but it is designed to fit into laptops. Since this is a desktop-class CPU with an unlocked power limit, it can operate within 45 to 75 watt power range and even higher when overclocked.

According to the reviewer, a Lenovo laptop equipped with GeForce RTX 4060 Laptop GPU (140W) and DDR5-5200 memory was used. Although this is not the most powerful GPU from NVIDIA, one should still consider this a capable gaming system.

This HX CPU was then tested in various CPU related tests such as Cinebench, SuperPI, y-cruncher or 3DMark. The tests have shown that despite featuring much fewer cores than Core i7-13650HX (14 cores) and Core i7-13700HX (16 cores), the Ryzen 7 7745HX is almost as fast as Intel CPUs in tests such as Cinebench or Adobe Premiere Pro, while being slightly faster in Adobe Lightroom and Photoshop.

Since AMD Ryzen CPU consumes less power than Intel, the discrete GPU has more power in games, which translates into minimally better gaming performance.

According to the reviewer, AMD CPU can gain a further 3 to 5% thanks to overclocking through AMD PBO (Precision Boost Overdrive). This feature can be enabled through the BIOS. Overclocking aside, the power efficiency is really good for this CPU, especially in gaming. The CPU consumes 50.9W on average while Intel CPUs 46.5W and 79W respectively at 1080p resolution. At 1440p, the Core i7-13650HX goes into lead, but only by a few watts.
