Apple power mac g5 quad 2.5 ghz

With two dual-core processors, the Quad has—as its name is intended to suggest—the equivalent of four standard G5 chips, twice as many as any previous Apple system. Dedicated collectors of Mac minutiae may recall, however, that onetime clone-maker DayStar Digital marketed a system with four PowerPC e chips , at speeds ranging up to MHz, for a few months in Just as Mac OS X divides chores between the two CPUs in older dual-processor Power Macs and between the two processing engines in the new single-chip, dual-core G5 systems, all four engines in the Quad can share the load.

And when they do, a faster memory system should ensure that the bus gets loaded in a hurry. If you give just a quick glance at the Macworld Lab benchmark results for the Quad, you might wonder what the fuss is all about—on the Speedmark test suite, the new system barely managed to edge out the previous Mac performance champ, the 2.

Speedmark 4 scores are relative to those of a 1. All systems were running Mac OS X The Photoshop Suite test is a set of 14 scripted tasks using a 50MB file. A closer look at the results, however, shows why the Quad really is a big deal—for the markets it was designed to serve.

On many of the real-world tasks that make up the Speedmark suite, the Quad only marginally outperformed the other models we tested; on six of the 15 tests, it even lagged slightly behind the 2. Even our Photoshop CS2 test, a set of 14 scripted tasks using a 50MB image, showed a speedup of less than 10 percent relative to the 2.

Those are huge time-savings, the kind that can convince even tightwad corporate bean counters to authorize trading up to new hardware. The moral of all this: the benefits of the Quad, even more than previous Macs, depend on the applications you run and the tasks you perform most frequently. On some tasks in some programs, those benefits might not justify investment in a Quad. Apple Mac G5 A Dual 2. Apple Mac Pro A Dual 2. Apple Power Mac G5 1. Apple PowerMac G5 2.
