Mac mini G4 1.5 GHzIn the OpenGL Hardware Lighting test, the old G4 Mac mini with Radeon 9200 is actually 20% faster than the new Intel Mac mini. In fact, even the CPU-dependent OpenGL Software Lighting test on the Intel Mac mini is faster. While it's true that the Cinebench OpenGL test may not be representative of gaming performance, this does illustrate just how much of a limitation the new Intel Mac mini's integrated graphics can be.

The good news is that the other benches confirm the great superiority of the Core Solo CPU over the G4. Clock-for-clock, Core Solo is 40% faster. Furthermore, we must not forget about the 1.66 GHz Core Duo Mac mini, which scores 471 in the CPU rendering test, over 3X as fast as the old 1.5 GHz G4 Mac mini.
