• Q 11. What do you need for GPU acceleration?

  
  

  A: The product will automatically use GPU acceleration as long as your computer has NVIDIA or ATI display card. No other item is needed.

  
  

  GPU: Graphics Processing Pnit, also occasionally called visual processing unit (VPU), is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the building of images in a frame buffer intended for output to a display. Their highly parallel structure makes them more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel. Password Unlocker Bundle now supports GPU, which helps to accelerate password recovery on MS Word/Excel/PPT/PDF files and RAR/WINRAR archives.

  
  

  Nvidia is best known for its graphics processing units (GPUs). Nvidia and chief rival AMD Graphics Technologies (formerly ATI Technologies) have dominated the high performance GPU market, pushing other manufacturers to smaller, niche roles.
