AMD’s 3D V-Cache Tech: Taking Gaming CPUs to New Heights


In the realm of gaming CPUs, innovation may not always be rampant. However, AMD has recently made waves with its 3D V-Cache technology which has positioned it as the frontrunner in the best gaming CPU competition. And now, AMD is taking this technology to laptops, starting with the introduction of the AMD Ryzen 9 7945HX3D, the world’s first mobile processor to incorporate 3D V-Cache.

The Power of AMD’s 3D V-Cache in Mobile Processors

The AMD Ryzen 9 7945HX3D is equipped with a staggering 144MB of cache on top of the chip, resulting in significant improvements in gaming performance. With 16 cores, up to a 5.4GHz boost clock speed, and a 55-watt power design, this mobile processor packs a formidable punch. According to AMD, the benefits of their 3D V-Cache technology shine even more prominently in mobile processors. Previous chips like the Ryzen 7 7800X3D and the Ryzen 5 5600X3D have demonstrated its prowess. However, AMD claims that the 3D V-Cache in the Ryzen 9 7945HX3D provides a remarkable 23% boost when operating under a 40W power limit, and an 11% boost under a 70W limit. These enhancements prove to be especially advantageous for mobile processors.

Unleashing the Potential: Gen-on-Gen Improvements

AMD proudly presents the Ryzen 9 7945HX3D as a 15% faster alternative to its baseline Ryzen 9 7945HX. This increase in performance spans across various games, with minor improvements in titles like Final Fantasy 14 and DOTA 2, as well as significant gains of up to 44% in games such as Cyberpunk 2077 and Deus Ex: Mankind Divided. While AMD’s claims do raise eyebrows, it is essential to await third-party benchmarks to validate these assertions fully.


It’s worth noting that the Ryzen 9 7945HX, the predecessor of the Ryzen 9 7945HX3D, has already shown impressive performance. In the Asus Scar 17 review, the base Ryzen 9 7945HX outperformed even the formidable Intel Core i9-13980HX with its monstrous 24 cores. Paired with a mobile RTX 4090, the laptop offered desktop-level gaming performance, achieving well over 100 frames per second (fps) in the most demanding games at 1080p. It is no coincidence that AMD has chosen to debut the Ryzen 9 7945HX3D within the Scar 17, set to launch on August 22. Leakers may have spilled the beans prematurely, but their information has been confirmed, leaving gamers excited to experience the Scar 17 and its upgraded components.

Awaiting Validation From Third-Party Benchmarks

While these developments sound promising, it is wise to wait for third-party benchmarks to substantiate AMD’s marketing claims fully. AMD conducted its testing of the Ryzen 9 7945HX3D at 1080p resolution, but it remains to be seen how much benefit the 3D V-Cache technology provides at higher resolutions. It’s also important to note that AMD referenced Intel’s Core i9-13980HX in its marketing materials, but without providing comparative performance data.

As with any new technological advancement, it is crucial to rely on independent testing and real-world usage scenarios to validate the claims made by the manufacturer. Once the Ryzen 9 7945HX3D becomes available, tech enthusiasts and gamers alike will eagerly await the comprehensive evaluations that will determine the true potential and market impact of this remarkable mobile processor. Until then, the gaming community can look forward to future encounters with 3D V-Cache and its promising applications in the world of computing.
