AMD has just launched its latest mobile processor, the Ryzen 9 7945HX3D, and it’s already stirring up the tech world. This powerful CPU comes with a whopping 128MB of L3 cache, a significant upgrade from its predecessor, and features a dual-chiplet design. With its impressive specs, the Ryzen 9 7945HX3D is set to outperform Intel’s i9-13980HX and deliver enhanced efficiency.

One of the standout features of the Ryzen 9 7945HX3D is its 3D stacked SRAM on one of the compute dies. This innovative technology allows for faster data access and improved performance. In terms of clock speed, the Ryzen 9 7945HX3D boasts a boost clock of 5.4GHz, similar to its non-V-Cache counterpart. Both versions of the CPU have a TDP limit of around 100W, making them twice as efficient as Intel’s Core i9-13980HX.

For now, the Ryzen 9 7945HX3D will be exclusive to ASUS notebooks. Notebookcheck recently tested the ROG Strix SCAR 17 X3D, powered by this new AMD processor, and the results were impressive. The Ryzen 9 7945HX3D showcased significant gains over its predecessor, the 7945HX, and consistently outperformed Intel’s Core i9-13980HX. Despite consuming more power, the Intel chip fell short in various games, with performance deltas ranging from 19% to 38%.

In head-to-head comparisons, the ASUS ROG Strix Scar 17 with the Ryzen 9 7945HX3D was found to be 19% faster than the Strix Scar 18 equipped with Intel’s Core i9-13980HX. Even when compared to the non-V-Cache variant of the Ryzen 9 7945HX, the 7945HX3D still held a significant advantage, with a 33% lead and a 20% performance difference.

When it comes to gaming, the Ryzen CPUs have always had an edge over Intel’s products, and the Ryzen 9 7945HX3D is no exception. In Cyberpunk 2077, a popular and demanding game, the Core i9-13980HX trailed behind, giving the Ryzen 9 7945HX and the 7945HX3D a lead of 12% and 13%, respectively.

Another CPU-intensive game, Shadow of the Tomb Raider, showcased the Ryzen 9 7945HX3D’s superiority. The Intel Core i9-13980HX struggled to maintain performance, averaging 144 FPS on the Strix Scar 18. In comparison, the Ryzen 9 7945HX3D delivered an astounding 89% improvement, solidifying its position as the fastest mobile processor for gaming.

Far Cry 5, a popular open-world game, also saw the Ryzen 9 7945HX3D dominate. While the Core i9-13980HX was marginally faster than the Ryzen 9 7945HX by 8%, it couldn’t compete with the 7945HX3D, which boasted a remarkable lead of 38%.

Overall, AMD’s Ryzen 9 7945HX3D Mobile V-Cache CPU is a game-changer in the mobile processor market. With its impressive performance gains over its predecessor and Intel’s flagship i9-13980HX, this CPU is set to revolutionize gaming on Laptops. ASUS notebook users will be the first to experience the power of the Ryzen 9 7945HX3D, and it’s safe to say that other manufacturers will soon follow suit. Gamers can expect smoother gameplay, improved efficiency, and an overall enhanced experience with this processor.
