Yes, it can handle large image files in Photoshop. Jobs told the Seybold crowds that the G4's speed is based on a core architecture that incorporates a 128-bit Velocity Engine that processes four 32-bit floating point operations in one computing cycle. To prove his point, Jobs did a demo with the G4, in which a 500MHz G4 proved to be approximately three times faster than a comparably equipped 600MHz Pentium III at handling a variety of Photoshop operations.
