GPUs are good for split join parallelism. They don't even really have real branching and you mostly have to loop a constant amount of times. Meanwhile any data without dependencies can be dealt with on a CPU core. Not only that, huge amounts of software could use a lot more concurrency if it was structured differently. Even a web browser (to my knowledge) doesn't split up DOM layout, parsing individual files, decompressing images, decompressing video etc. into separate threads for each file.
