Graphics Processing Units (GPU?s) are specialized hardware desgined to discharge computation from the CPU for intensive graphics applications. They have many cores (thread processors), currently the Tesla K40 (Kepler GK110) has 2880 cores at 745 Mhz (Builtin boost to 810, 875Mhz). The difference between the GPUs architecture and standard multicore processors is that GPUs have much more computing units (ALU?s (Arithmetic-Logic Unit) and SFU?s (Special Function Unit), but few control units.The programming model is SIMD (Single Instruction Multiple Data). GPUs compete with many-core processors (e.g. Intel?s Xeon Phi) Knights-Corner, Xeon-Phi 60 cores).
