The company's public presentations -- Stevenotes in particular—often featured lengthy segments pitting a high-powered Compaq or Dell computer against the Power Macintosh in a series of benchmarks and scripted tasks, usually in Adobe Photoshop. These presentations often showed the Power Macintosh besting Intel's Pentium chips by margins significantly exceeding 50%, but independent benchmarks did not bear this out. InfoWorld reviewer Jennifer Plonka reported that the 400 MHz G3 was 11% slower than a comparably-specced Pentium II-450 in an Office applications suite test, while Photoshop 5.0 was faster by 26%. And in 2003, Maximum PC ran a variety of gaming, Photoshop and LightWave 3D benchmarks, and reported that the Dual 1.25 GHz G4 system was about half the speed of a dual-processor Intel Xeon Prestonia 2.8 GHz system. A related criticism leveled at Power Mac systems from this time, particularly the G4 Mirrored Drive Doors, was the increased fan noise level compared to older systems.
