Constantly playing the “PowerPC really is fast… when you sacrifice virgin blood and make 110% use of AltiVec!” game is really kind of pointless for them. Over time, I’ve started to believe that there were two primary reasons Apple ditched PowerPC:ġ) Marketing. At least, that’s what I told myself when I found out the new Mactel can run XCode builds way faster than my DC 2.3 PowerMac, although ironically enough, Apple broke my must-have PPC-only app (Matlab) in 10.4.4. In the meantime, just be happy that you can run all your PowerPC software that doesn’t have a UB equivalent. That’s okay - x86 will come to save the PowerMac soon enough. Unfortunately, the G5 is more comfortable hanging out with circa-2003 processors instead of modern x86 chips. The PowerMac G5 is still a good machine - for it’s era. By your logic, the Quad is a pokey machine, because it doesn’t stand up well to an 8-way Opteron server…ĭon’t get me wrong. That seems to be the consensus on the macnn forums, which entertainingly enough is full of people who seem to actually like Macs, as opposed to people who have a weird attachment to PowerPC.Īnd the point of the comparison is? The Quad costs twice as much (without monitor), weighs twice as much, sucks down three times the electricity, and makes much more noise. On integer code, the new iMacs will beat anything short of a Quad. Second, its unfortunately not the whole story. Welcome to PC video gaming performance circa 2003.įirst, I’d hope the iMac isn’t faster than the DC PowerMacs, since the latter cost quite a bit more. That’s all the CPU load a second processor will take off when running a single-threaded application.Īctually, Apple’s OpenGL stack is so bad that games are quite often CPU dependent. What tiny CPU is used is the result of daemons running in the background, which kick in once in a long while (from the POV of the processor). Take a look at your CPU utilization with nothing running. Naturally if you don’t have another core the first one has to do all the work. If you have a single threaded app that calls OS services, those services will run on the same processor as the application. It’s a set of libraries and the kernel, which behaves like a shared library in that it runs on whatever core the thread that called it was running on. Second Mac OS X and other OS related stuff is on the other core as well even further freeing up the first core. Sound is like, what 3% of the total overhead? What is got you excited is you got a taste of PowerMac performance in a consumer box, but when the new 3D games arrive the temptation to get a Quad will show itself. My Dual 2 Ghz (3 years old) runs about 100 and the Quad is a monster. It also scores not that much better than a iMac G5 on X-Bench scores. So the Core Duo isn’t a great leap of performance power. However the Core Dual is 32 bit and is not faster than a most dual core PowerMac’s which are 64 bit and can beat the 4GB RAM limit. So yes you got a newer better iMac, it’s to be expected when you upgrade, the machine is 2x faster (in some tests) than a single core iMac G5, but that’s to be expected because DUH, it has another core. I can actually run 2 3D games at once above 40fps each. Because 3D games are mostly video card dependant. Third the hard drive has a bigger cache than before, which makes the map and game loading faster.įourth the video card in the new iMactels is much more powerful than the iMacG5įifth when UT2005 or 6 comes out it will run like a pig on your iMactel, but with my Dual 2 Ghz PowerMac G5 all I have to do is upgrade the video card. Metronome won't work in Classic because that would violate one of Apple's biggest rules and that's that you can't access hardware directly from the Classic layer and that's exactly what Metronome is trying to do.First of all UT2004 throws the sound on the other core to get some game engine performance. I've been told by my OS X guys, there isn't really a way to duplicate Metronome in OS X without adding a few kernel extensions and we'd rather not do that. "There is no Metronome for OS X because Apple System Profiler under OS X generally does a good job at reading the upgrade. Could you tell me where I could find the upgrade? Or another software utility for OS 10.2.6 and soon 10.3?" I'm looking for Metronome's upgrade for mac os 10, or any software utility which displays bus/processor speeds, secondary cache size and speed and the temperature for powerPc G4 processor. "Everything's ok and easy to install, but I don't find metronome OS X, only OS 9 (in apple menu items) that doesn't work in classic (doesn't open).
