Ok I am a bit confused on everything about the G5.
1.Isn't the PowerMac already Dual Core(meaning two cores in one CPU) or does it just have 2 G5 CPU's?
2. What do you mean by quad? Is it 4 actual CPU's? Or two CPU's that both have 2 different cores?
3.Is hyperthreading mean it is one CPU that has four cores?
4.I think I understand but am just getting mixed up....someone please enlighten me.
1) Current PowerMac models have 2 separate G5 CPUs which are single-core.
2) Could potentially mean either as it essentially boils down to the same thing, although two dual-core CPUs is more likely than 4 single-core chips. Either way its 4 logical cores.
3) Hyperthreading is Intel's marketing term for a technology that improves processor performance under certain workloads by providing useful work for execution units that would otherwise be idle, for example during a cache miss. When running optimal code it is like having double the number of logical units, but in practice this level of efficiency is very rarely achieved.
4) Hope that helped!
Edit: doh! Beaten to it!
