Dual Processors

it doesn't work like that, you dont add speeds together. you still have a 3GHz system. the only difference is that that you can execute more threads at a seemingly greater speed. also, you cant even compare the performance as a equivalent by adding the speeds as the increase in system speed isn't linear, you get overheads etc.
 
pentium dual core cpus are very different from AMD dual core cpus. Intel`s cores are connected to gether alowing them to commuincate with each other. So its acting as one big core with 2 segments. While AMD`s cores are separate (A TRUE DUAL CORE CPU). So they cannot communicate, acting as 2 individual cpus.

So when Intel says 3GHZ thats the overall & when amd say 2ghz for example this will be 2x 2ghz.

Not the best explanation i know but i hope this helps

you got that the wrong way around :D
 
amd dual cores use an internal hypertransport link allowing them to communicate with each other. intel cpu's are contructed as two spearate cores which act independantly while having to share the front side bus for data for each core.
amd were looking at dual core long before intel, this is why we had the hypertransport interconnect system. it allows very fast communication between devices such as the memory, graphics as well as cpus. although it allows external communications to devices it allows two cores to directly communicate with each other and thus be linked directly
 
if youre planning on getting a g5...my god, it wont even matter. you can throw anything at that computer and it wont even flinch. especially with 16gb of ram....that is just freakish.

i think he's on about a G5 server, although i cant be sure
 
g5 servers are slow in comparison to opteron or xeon. i read an extensive review and comparison a while back...
also the g5 pales in comparison to pc's when it comes to gaming, which will slow it down considerably.
but for music and graphics, they are still on top i believe. in fact they are still dream stations

here we go.

page 6 compares multiple clients on apple, opteron, and xeon with and w/o ht. ouch.

Thats becuase G5's of for MAC's, and MAC gamers dont exist, due to the whole 6 mac games exsiting.
 
If I put dual processors of 3 Ghz each will I have 6 GHz on my PC all together?

Yes but only in a literal sense, you will only have 3GHz per thread

NO, its usally summin like 1.5 ghz per core. What CPU are you refering too ?

Uh... we're talking about dual procs, not dual cores

The Apple PowerMac G5 with two Dual Core CPUs

So are we talking dual G5s or a single-dual core? :)

Chip in question is a G5

Actually that's incorrect (or correct in a meaningless context). The individual Prescott cores are unable to directly communicate with with each other and are forced to communicate via FSB. The AMD X2s however are able to communicate with each other via a x-bar

So when Intel says 3GHZ thats the overall & when amd say 2ghz for example this will be 2x 2ghz.

Neither AMD nor INtel use clock speeds as a a marketing label anymore

amd dual cores use an internal hypertransport link

I pretty sure it a x-bar, the hypertransport is for external access

Id like to see it do 8 DVD encodes concurrently.
