cpu - Less pieces of high GHz core or more pieces of less GHz cores
2014-07

I am planning to buy a used computer for video editing, now I have found one with 2x E5310 CPU for a decent price.
And I havn't found any information which is better for video editing (Sony Vegas, Adobe Premiere apps): Less cores with higher clock rate, or more cores with lower clock rate?
This CPU is the second (2x 4 cores with 1.6GHz)
Any advice welcome!

Its all dependent on software and OS you are using. Some software better working with multicores some with higher frequency. AFAIK best option would be to get quad core. I cant tell if that will work for video editing, but that worked well with 3d graphics(2x3.1ghz => 4x2.2) In your case i wouldnt exchange for E5310, because that cpu is very old, and might not support some features, that would increase speed of rendering your video.

The big question regarding core count vs raw frequency is a question as to whether the apps are multithreaded, and whether the main operation the app can perform is multithreadable. A single thread app will only run faster if you increase teh frequency, but if the task is broken into multiple threads then more cores is better.
in your case, those apps are all multithreadable, but the act of rendering is often a single thread, so frequency is very important. Having the right instruction set is also critical for this kind of task (SSE4 for instance).
in the end, you are not doing a trival task, so I would look for a quad core at > 3GHZ, preferably with hyperthreading (giving you 8-threads of seemingly-simultaneous processing). I recommend the I7 2600 (4x 3.4GHZ HT).

In this case processor is just an identifier (which starts at 0). You have two processors, so they're 0 and 1. CPU cores means the number of cores in each physical processor (two here).

It is two processor cores on one die essentially like having a dual processor system in one processor.
The central processing unit (CPU) is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions.
