GPU Flashcards
What does GPU stand for?
graphics processing unit
What is a GPU
A specialised electronic circuit designed for the manipulation of memory for the output of the computer (or any machine)
Cpu are what?
CPUs are general purpose processors
GPUs are what
GPUs are designed specifically for graphics
What is the architecture of a GPU?
parallel architecture of small cores designed to tackle tasks simultaneously
GPU is often considered what?
a co-processor to the CPU
Explain why a GPU is more suitable than a CPU for rendering 3d graphics?
CPUs are general purpose processors (1)
whereas GPUs are designed specifically for graphics (1). And so likely to have built in circuitry/instructions for common graphics operations (1).
GPUs are able to perform an instruction on multiple pieces of data at one time (1)
often we want to do this when processing graphics (e.g. transforming points in a polygon or shading pixels) (1)
which means it can perform transformations to onscreen graphics quicker than a CPU (1).
if gpu wasn’t present what would happen
the performance of the CPU would drop, as it normally reduces the workload
What else is GPU used in?
physical/scientific modelling encoding digital distribution CAD computer finance fluid dynamics
