The change which you will hear most about is the Velocity Engine, which is marketing‑speak for a parallel‑processing influenced vector processing unit which is specifically designed to give a speed bump to the complex repetitive calculations that you find always quoted as being used in 'graphics and video' applications (the high‑end G4s will apparently do the MPEG decoding of their DVDs in software, not in a hardware accelerator!), and which computer‑using musicians might recognise as being the province of audio processing too. The G4's PowerPC 7400 processor chip may add only an extra 0 to the 740 chip used in the G3 machines, but there's a number of significant changes which mark this as the fourth generation of PowerPC processors. Once I could laugh off, but twice? G4ĪrtMatic: where sound and pictures meet, mix and mingle. My computer‑buying timing is beginning to look like more than just an accident.
Now I'm not a 'leading‑edge' chaser, and I've taken my time changing Operating Systems (most of my work is still done using MacOS 7.6.1, and it's only because the recently acquired 'Blue & White' G3 came with MacOS 8.6 that I've discovered how similar and yet different it is without the push, I suspect that I'd still be a pure System 7 user), but I'd really have appreciated just a little longer at the front of the race.Īnd, of course, despite all the rumours saying that they would arrive late this year, or early next year, the new G4 Macs were announced just a few weeks after I bought my G3. In my case, the 'same casing but miles faster' beige G3 Macs were gleefully announced just a few weeks after my 7300 arrived. Nature may abhor a vacuum, but computer development seems to hate contentment. For a few weeks the 200MHz 7300 was at the top of the Mac heap, and I got a warm feeling knowing that having several times the standard cache was getting me an extra few percent in speed. When I first bowed to the inevitable and bought a PowerMac, I weighed everything up carefully, and bought at the leading edge, just as you are supposed to.
