GPU

  1. 1. By Shishir Gupta 3rd semester CSE
  2. 2. Umm.. GPU?? GPU : Graphics Processing Unit CPU : Central Processing Unit GPU complements CPU which performs general processing, by more efficiently handling Graphics Calculations. Can also accelerate Video transcoding, Image processing and other complex computations using concept of GPGPU (General-purpose computing on Graphics Processing Units). Eg. CUDA (Compute Unified Device Architecture).
  3. 3. THEN AND NOW Intel ASCI Red/9632 : 2,379 GFLOPS - Fastest Supercomputer (World), 1999 PARAM PADMA : 1,000 GFLOPS - Fastest Supercomputer (India), 2003 NVIDIA GTX 780 Ti : 5,046 GFLOPS - Fastest GPU (General), 2013 GFLOPS : Giga FLoating-point Operations Per Second. A measure of computer performance.
  4. 4. Memory is the boss? NO! GTX 680 (2GB) GT 430 (4GB) Memory : 2GB Memory : 4GB Price : Rs. 41,195 Price : Rs. 4,520 Computation power : 3,090 GFLOPS Computation power : 269 GFLOPS
  5. 5. WHICH GRAPHIC CARD SHOULD I BUY? Deciding factors:• Display resolution (computation power required). • The underlying GPU (computation power you can get). • Amount, Type of memory (DDR3/DDR5). • Factory overclock (extra power at same price). • Cooling design.  Liquid Cooling.  Air Cooling : Axial, Centrifugal.  Axial : More efficient cooling. Blows waste heat inside cabinet.  Centrifugal : Lesser efficient cooling. Blows waste heat outside cabinet.
  6. 6. THE UNCROWNED KING NVIDIA GTX 780 Ti • Code name : GK110 • Fabrication process : 28nm • Stream Processors : 2880 • Transistor count : 7.1 Billion • Core clock : 875/928 MHz • Bus interface : PCIe 3.0 x16 • Memory : 3GB • Memory speed: 7000 MHz • Type/Bus width : GDDR5/384 bit • Computation power : 5,046 GFLOPS • Price : $699
