AMD has announced the new Ryzen 9 7945HX3D, the world’s first notebook CPU with the company’s 3D V-Cache technology.
The 7945HX3D is essentially the 7945HX but with double the L3 cache. While the L1 and L2 cache remain at 1MB and 16MB, respectively, the L3 cache goes from the 7945HX’s sizable 64MB to an impressive 128MB for a total of 145MB cache.
Introduced first on the Ryzen 7 5800X3D desktop processor last year, the AMD 3D V-Cache technology essentially stacks an extra layer of memory on the CPU die. While most apps show no improvement from the added cache, games tend to benefit tremendously from it. The extra memory on die means games don’t have to access the slower and physically distant system memory as often, resulting in faster processing of each frame and higher frame rates overall.
