For those who are not familiar with the author of this blog, he is a PowerPC enthusiast and the maintainer of TenFourFox, a Firefox port to PPC OS X. He's also currently working on a new PPC JIT for (modern) Firefox on Linux (a project for which he is looking for volunteers to assist him[1]) to bring it to speed parity with Chrome on PPC (which already has a PPC JIT).

As fun as this is (and as much as I appreciate putting good old hardware to use and as much as I like PPC): the power consumption alone wouldn't make this a winner :( I have a PowerBook G4 DVI, iBook G4, B&W G3, GbE G4, Dual G5 here, I want to get rid of them but I like them too much. Yet I can't run them for fun all day long either because the amount of power they eat >:( The problems of a hardware connoisseur.

Why the obsession with PPC? Don't you feel you could put your time + effort into something more modern that isn't dying?

o_O Compared to what? G3s and G4s are pretty light on power usage - IIRC they use around 10-15w? The G3s were even less. The i7 in my desktop uses at least 95w, and some reviews suggest it's more like 140w lol. Edit: Unless you're pairing them with CRT monitors...

Compared to say.. a 1W ARM CPU. Those are faster and use less energy.

Author here. Power consumption on this unit is about 21W. Is the CPU/watt ratio less than later units? You bet. But it's not bad, it's free, it's not in a landfill, and it's more than enough grunt for the basic tasks it's doing.

Yeah, those Mac Minis can go quite low. But still the CPU power from any PPC vs. an ARM or low-end x86 is a bit inverted. A low-end ARM or x86 that is faster than any of the PPCs while using less than half the power (in the 1W to 8W range) does make a dent.

Why do you say it's dying?

PPC is far from dead. You can buy brand-new POWER9 workstations with up to 44 cores (with SMT4 for 176 threads) from Raptor Computer Systems. They are also about as open as a modern computer can be with board schematics included with every system and only one component with closed firmware (the BCM5719 network controller, which is currently being reverse-engineered so an open firmware can be developed).

I have the same problem with two G5 Xserves. They’re just too cool to get rid of.

Wow, didn’t know that, amazing. What is the main use of those machines?
