Dual core vs Dual cpu?

[Nvidia2000]

I'm just wondering is there big difference in dual cpu/dual core? Let's say Opteron 180 vs 2x Opteron 250 (both socket 940).

i belive in general dual core is a bit faster in chip to chip communication. atleast in AMD chips and intel yonah and upcomming chips. because they can communicate with a crossbar or bus thats directly on the chip and dont have to go via the HTT/FSB. though, because they both share the same HTT/FSB, memory bandwidth is a problem. a good comparison are the presler/X2. netburst, if clocked high enough, can keep up with AMD chips. but because de intel dual cores need to go via the FSB to communicate with eachother because their really 2 chips on the same die instead of true dualcore, the chip to chip communication latency is very high and their much slower.

so i guess for desktop PC's dual core is better, because memory isnt much of a problem (the most that will be used, like a game, only uses max 2 gigs. so nothing there) but for servers dual proc would still be better because of more memory bandwidth.

best of all would still be dual dualcore's but thats a different story all together

I saw some benchmarks, and they bear out my own observations, essentially no difference at all. Its hard to really tell, as they mothboard,memory, etc... will make a difference in the platforms.

Dual CPU=Dual Core->HT

I think for day-to-day usage, Dual-Core CPUs perform better than Dual-CPU setup. I'll try to find a benchmark for you. I'm pretty sure I've seen at least one before.

Dual core is also easier to build and use in a home setup. There are many more motherboard and other basic build options for a dual core CPU than a dual CPU setup.

 

[formulav8]

Dual Core shares the same memory bandwidth.

Dual CPU's has it own memory bandwidth.

So, in high bandwidth situations the dual cpu would be best. But if core communication latency is important, then the dual core will be better.

So, its really based on your needs.

Thanks classy. Awesome.
I got so very much information about this subject and it even gave information on the OCZ Power Supplys that interests me.
