Why are GPUs so big, while CPUs are so small?
In: Engineering
Wait a minute, are we talking about graphics cards or GPUs? GPUs are the big chips on the graphics card that do the actual work.
Why are GPUs so big and CPUs so small? Because GPUs contain a lot more transistors than CPUs. Why do they contain more transistors? Because it is much easier to throw more “workers” at the things GPUs do, so it makes sense for GPUs to have more “workers”. Graphics (and some other computing problems) is usually a bunch of relatively simple computations, but a shit ton of them (e.g. calculating the color of a pixel on screen is not complex, it’s just that there are so many pixels). CPUs on the other hand usually do a few computations that are relatively complex (with many steps that also depend on the result of previous steps and sometimes steps are taken depending on the results of previous steps and sometimes they are not taken).
