When compared with GBA, the PSP is quite similar in terms of launch time and sales, but in terms of hardware configuration, the PSP proved to be much stronger when it was said to be as strong as the PS1 and could run games up to several GB in size. Introduced by Sony in E3 2003, the PlayStation Portable became a highlight throughout the year and soon after its release in late 2004, it became the most powerful gaming device of its time.
