Dual Processors

Apokarteron · 12-18-2005, 05:23 PM

If I put dual processors of 3 Ghz each will I have 6 GHz on my PC all together?

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

The Apple PowerMac G5 with two Dual Core CPUs

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

Really ?, please can you corret ??. This is what ive been told by micromart pc mag

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

WOW, cheers for clearing that up for me Lee

and sorry for the confusion Apokarteron !!
