Does a motherboard with two CPU's have better performance than a motherboard with a single CPU? :stare:

It's mainly server type boards that use dual cpu's and they are awesome at multitasking but for normal home use it's unlikely to be worth the cost. For highly threaded solutions they are obviously better but otherwise not.

Hmm that reminds me I have a dual xeon motherboard floating around somewhere at home, really should install it and use it.

I find them to be particularly useful when you're at your local lan. Then you can brag about all the extra performance you'll never use.

Dual hexacore ftw

Which is faster , in everyday use
a Slow CPU speed Dual Core (lets say 1.6Ghz or 2Ghz)
a Fast CPU Speed Single core (3Ghz)

Im betting on the Single core

So they would be good for gaming? I suppose it depends on the CPU type though.
Thanks guys.

1101 depends on what you're doing, dual cores multitask better but single threaded apps get no advantage from them. On the whole the dual core would feel quicker.

Chaz, not really. Games still mainly use 2 cores or less and server type CPUs are designed for server type workloads not gaming. A fast dual core chip on a cheap desktop board would game as well or better than a dual CPU motherboard with two CPUs.

Ok thanks. I will get away from dual CPU boards.

In everyday use? Probably the dual core.

Do you mean Dual-Core in a single CPU or two single-core CPUs running in SMP?

Two Dual core CPU's on one mobo. Two sockets in one motherboard.

2 dual cores on 1 motherboard seems kind of pointless. Surely 1 quad core would be *better*.

I know eh. A quad core would be better.

Likely to be cheaper at any rate

What about dual quads. You got to remember dual core were out before quad. We have 3 dual core2 and a dual quad.

It would be cheaper to go with a single CPU rather than two CPU's.

It is important to distinguish between multiple cores vs multiple cpus, if you are considering what type of system to get for a workstation don't even bother with multiple CPUs, its not cost effective.

As for the whole "most apps aren't mutli threaded" it is not 2007 any more, there are actually very few apps now that don't take advantage of multiple cpu cores (unless you never update your apps), and you are foolish if you think that no new or recent games are multi threaded.

Also consider this, are two hands better than one? think of a complicated task, and how much longer would it take to do it with only one hand, multi-core CPUs feel a lot faster because they can effectively handle multiple tasks at once, but try doing multiple tasks on a single threaded CPU and things start to go real slow, so comparing a dual core 1.6 to a single 3Ghz is pointless, regardless of what software you use, you are always multitasking, it has almost always been that way because we have an OS that uses CPU time, then you run software on top.

Exactly. Thanks.
