What exact model are you looking at?
1 core can run multiple threads, just not all at the same time

 

[lilly_lilly]

exclude models and hyper threading technology...just in general, which matters more; as per question

 

[rgd1101]

Since you can't have less thread then the # of core, not sure what you are trying to ask.
If you exclude hyper threading, there even less sense about your question.

Given that the cores are equal in power (Intel vs Intel, AMD vs AMD), more cores > more threads for multitasking or processes that scale to multiple threads.

For instance, i3 (2C, 4T) vs i5, the i5 will handle heavy workloads or multitasking a bit more swiftly.

Now if you're comparing say, an 8-core AMD FX to a 4-core i5, the Intel cores are SO much more powerful that they bridge the gap in most heavily threaded workloads, and the single-threaded performance is way ahead.

thx that solved my doubt... that u can't have less thread than core

Look at tom's CPU hierarchy article in today's news.

For mostly apps than games, Intel is worth the little extra cost. They benefit apps more than gaming.

AMD is a good option if you are mostly gaming, but will be a little slower in some apps.
