Voidness said:Come on people. It's basically dual dual-core processors, that's 4 CPUs. We might be getting this as early as Wednesday if the Powermacs get the PowerPC 970MP. Although It won't have Hyperthreading, which is pretty much useless in most cases.
Fabio_gsilva said:And what about those processors named Ituran, or Ituran2? They can't be used on future Powermacs???
A "core" is everything you've always called a CPU - registers, ALUs, cache, etc.Evangelion said:No, you are quite mistaken. It's propably two CPU's, each with two cores and hyperthreading.
two dualcore CPU's, four cores, eight logical processors. Simple, really.
AidenShaw said:There's almost no way to determine from a program (short of calling specific core-aware APIs) whether a dual-CPU machine contains two single-CPU chips or one dual-CPU chip (dual-core chip). (Not quite the same for HT - you can easily check performance and see that your two CPUs aren't about twice as fast.)
Benjamin Rozens said:Now come on - think
You have got a cool quad chip
a 30 inch LCD screen (I here it maybe plasma)
I repeat "a core is a CPU".Evangelion said:I think it's pretty safe to assume that ANY quad-CPU workstation now or in the near future, mean 2x dual-core CPU's. Everyone is moving to dualcore, and having 2x dualcore CPU's makes alot more sense than having 4x single-core CPU's.
You mean dual-core, quad-proc G5s, don't you?rxse7en said:Just give me dual-core, dual-proc G5s tomorrow and MacIntel can feck off for another five years.
AidenShaw said:You mean dual-core, quad-proc G5s, don't you?
A "dual-core, dual-proc" would be a single chip, with 2 CPUs like today's dual G5s.
It would be a great way to make a dual-CPU iMac G5....
Hattig said:He was correct.
A dual processor system, where each processor has two cores.

AMD64 Dual-Core Technology directly connects two processor cores on to a single die for reduced latencies between processors
http://researchweb.watson.ibm.com/journal/rd/494/sinharoy.html
This paper describes the implementation of the IBM POWER5 chip, a two-way simultaneous multithreaded dual-core chip, and systems based on it.
...
Figure 1 shows a high-level system structure for POWER4 and POWER5 systems. POWER4 systems were designed to handle up to 32 physical processors on 16 chips.

You should have said:
I think it's pretty safe to assume that ANY quad-CPU workstation now or in the near future, mean 2x dual-core chips. Everyone is moving to dual-core, and having 2x dual-CPU chips makes alot more sense than having 4x single-CPU chips.
"Dual-core" is simply a cheaper way of getting dual-CPU, and a much cheaper way of qetting quad-CPU.
AidenShaw said:AMD says dual-core is "two processors on a single die"....
IBM thinks that a core is a processor as well:
My main point is that a "core" is logically everything that you've always called a CPU.
In common language, calling a single dual-core system a "dual CPU" and a dual-dual a "quad CPU" is simpler, clearer, and much less prone to confusion.
There's no need to check bus loads - a core is everything a CPU has always been, regardless of how it's connected or built.
That'll do !rxse7en said:Just give me quad-core G5 tomorrow and MacIntel can feck off for another five years.

Platform said:Do you mean Ithanium![]()
If so, don't think so becasue they are very rare and has had little development.![]()
Evangelion said:Well duh! My point is that people are getting extatic at the idea of "quad-CPU intel PowerMac", while we are expecting 2x dualcore G5 PM's, which ARE "quad-CPU PowerMacs". Quad-CPU machines are nothing strange these days, and I fail to see what the fuzz is about.
I think it's pretty reasonable to talk about CPU and cores. CPU is the chip that's in the computer and that chip may have one or more cores in it. But if we started calling the individual cores as CPU's, we would start to REALLY confuse things! Add to that the weirdoes who call the computer itself (in case of PM, the tower) CPU's. Then we would have something like "My CPU has two CPU's in it with two CPU's in each CPU". No, I maintain that it's best to talk about CPU's and cores, with each CPU having one or more cores in it. In the past it did make sense to think that core == CPU == core, since each CPU was just a single core. But things are changing. When people think about CPU's, they think about the processors in their computer. It does not matter in the end how many cores that CPU has, to Joe Sixpack that is a technical detail he's not interested in. When he looks in to his 1x dualcore-machine, to him, it will have a single CPU.

http://en.wikipedia.org/wiki/Central_processing_unit
A central processing unit (CPU) refers to part of a computer that interprets and carries out, or processes, instructions and data contained in the software.
The more generic term processor can be used to refer to a CPU as well; see processor (disambiguation) for other uses of this term.
Microprocessors are CPUs that are manufactured on integrated circuits, often as a single-chip package. Since the mid-1970s, these single-chip microprocessors have become the most common and prominent implementations of CPUs, and today the term is almost always applied to this form.
The term "Central processing unit" is, in general terms, a functional description of a certain class of programmable logic machines. This broad definition can easily be applied to many early computers that existed long before the term "CPU" ever came into widespread usage. The term and its acronym have been in use at least since the early 1960s.
