AMD Ryzen 9 7945HX3D: Boosting Gaming Performance
The AMD Ryzen 9 7945HX3D is now available, the first laptop processor to use 3D V-Cache technology. The chip uses extra L3 cache to boost frame rates in games, and the boost is exclusive to the Asus ROG Strix Scar 17 X3D, which will launch on August 22. The announcement is exciting, but we’d love to see more chips with the extra cache, and the Asus deal is a shame.
The Ryzen 9 7945HX3D has 16 cores, 32 threads, and a boost clock of 5.4GHz, though it’ll typically run at 5GHz. It has 128MB of L3 cache and a TDP of 55-75W, and the extra cache should improve performance without requiring more energy or cooling.
AMD claims the Ryzen 9 7945HX3D will deliver gaming performance around 15% higher on average compared to its non 3D V-Cache equivalent. The boost will be more noticeable in laptops with lower TDPs and clock speeds, and games benefit the most from higher levels of cache.
It’s exciting to see the first chip, but we’d love to see more chips with 3D V-Cache in the future. The exclusive deal with Asus for the Ryzen 9 7945HX3D is a shame, but there’s hope for more mobile processors with 3D V-Cache in the future.
The extra performance boost is more visible in laptops with lower TDPs and clock speeds, and the desktop Ryzen 9 7950X3D has already proven it can handle the extra complexity from having one chiplet with the L3 cache bump. We’d love to see a more affordable eight-core laptop chip with 3D V-Cache.
