The Ryzen 9 7945X3D is essentially a desktop Ryzen 9 7950X3D repackaged for laptops. [credit: AMD ] For a couple of years now, AMD has offered special versions of its desktop processors with an extra 64MB chunk of L3 cache included. This cache is layered over top of the existing CPU silicon, earning it the name "3D V-Cache," and it has proven especially successful for accelerating cache-sensitive software like games. Today, AMD is announcing the first 3D V-Cache processor for laptops, the Ryzen 9 7945X3D.
