www.squarespace.com/?associateTag=bwana In this video I answer a question via email (help@bwana.tv) from Xinchro who asks what is the difference between a dual core and dual processor. One of the major differences between dual core and dual processor is that one shares system resources while the other one has its own resources. Dual core processors have two cores on the same processor while dual processors are two physical processors. Dual core is popular lately since it's a low cost option for most people whereas dual processors are more expensive. Software wise, all this depends on whether your software supports multi-threading. Most major programs do not support multi-threading yet (like most games) but the support is slowly coming to fruition. There is also the possibility of a combination of dual cores and dual processors. For example, the newer Mac Pros have 4 cores (quad core) and you can buy a single quad-core or a dual quad-core (for a total of 8 cores). There's much more to this topic, but this is the quickest way I can explain it without going into massive, confusing detail. Thanks for the question, Xinchro.

I think you missed the mark on the dual core vs dual processors discussions. Dual processors might have their own caches, the caches on the dual cores and quad cores today are usually large enough to handle the sharing. Dual processors cannot wait on each other for work (resource sharing), while dual cores can. Having one bus instead of two is better. The only reason to go to a dual processor is because the current quad cores are not enough (ie. Mac Pro, Unix Servers, Mainframes, etc). In those big boxes the interconnects tend to be much more streamlined and the operating systems can take advantages of both the cores and multiple processors on the planar boards.

Like I said, there's much more to this discussion and wanted to highlight the major differences without adding more confusion. Your more detailed explanation would have definitely confused him. My goal is to simplify as much as possible.

Many people are confused and used to ask the difference between Core 2 duo and dual core or Core duo. So i wrote an article long back explaining everything in layman’s language. Read it here
