My everyday (apart from the BlackBerry which is gold) is a12 y.o. single core ppc 7450 aka a ppcg4e@ 1.67ghz with morphos, an up to date os.This ppc g4e is oblivious to meltdown, but technically marginally vulnerable to spectre, but under testing,under attack has shown just go to 100% cpu usage and what the tests pull from the pipeline often isn't even accurate.If I get an attack it'll just goto 100% cpu and I'll have to reboot
And speed wise with all these patches killing branch prediction,my machine is now as fast as the latest.
There IS security in obscurity. ;)

Well, there it is from gpuboss benchmarks. Most of those historical stats would be before the meltdown patches came out. Mine is after, probably along with the smaller count of other bottom scores. Still runs pretty nice especially considering its 7 year old architecture, though.
