Here is a report from the field. Exactly one week ago I bought a Mac. My very first Mac. A dual 1GHz G4 + 1GRam and all the other normal stuff. I’m absolutely impressed!!! After the initial shock of everything being new and different I must admit that this is the easiest “thing” to use, administer, configure and it is by far the prettiest interface and hardware out there. I still have the AMD and Intel boxez (indeed) but they have not seen much use lately. The only drawback, which to me is significant, is that linux+XWindows doesn’t run on this Mac (yet). The video card ... again, other than that Yellowdog linux boots just fine. The interesting thing is that the G4-1GHz outperforms the PIII-1GHz, P4-1.8GHz and Xeon 1.7GHz. My test was an FFT routine (class) I use at work. The code is not optimized in any shape or form for the G4. The worst case is when doing 64K-samples FFT (using floats). G4 - 18 fft/sec Xeon 1.7 - 6.04 fft/sec P4 1.8 - 5.93 fft/sec pIII 1 - 5 fft/sec Yes ... the cache got the best out of the Intel Chipsen. ;-) Until this point the G4 was still better than the rest of them. All of the CPUs scaled “n log(n)” in the range of 1K-...-32K samples. If interested I can send you the source code to test yourself. It, almost, seems that one can write a chess program using “float” instead of “int” and still get the same performance. BTW Does anyone have test(s) you would like to try on a G4?! If reasonable I might do it. Regards. hristo
