The 8 cores in the non-3D block run at the same 5.4Ghz boost clock as the 7945HX, but AMD hasn’t released details of the lower maximum boost clock for the 3D V-Cache block. In the case of AMD’s 16-core Ryzen 9 7945HX3D, only one of the 2 blocks of 8 cores gets the additional stacked 元 3D V-Cache because it has a negative impact on clock speed. The 3D V-Cache packaging technology stacks additional cache layers on top of the CPU, which means you can increase the CPU’s memory without increasing the size of the die or shrinking the logic circuits. The 7945HX3D uses what AMD calls “3D V-Cache Technology” to double the amount of 元 cache from 64MB to 128MB compared to the conventional 7945HX. ![]() ![]() ![]() The ROG Strix Scar 17X3D comes with a new variant of AMD’s Ryzen 9 7945HX Dragon Range processor called the 7945HX3D.
