E2140 1.8Ghz Dual Core Vs. E4400 1.8Ghz Core 2 Duo

Explained in another thread I need to replace a dying computer for someone. Am looking at some refurbished Dell machines.

One has an Intel E2140 1.8Ghz Dual-Core processor and the other has Core 2 Duo E4400 1.8Ghz. Is there a big difference between the two? I notice the first has 1MB cache, the other has 2MB cache. Would I be wise to stay away from one as opposed to the other for any particular reason?

  1. cache dont really matter much performance is about the same surprisingly
  2. E2140 is 1.6ghz, and has half the cache. E4400 is 2.0ghz. It will be slightly faster, mainly due to the extra hz.
  3. If you can get a Refurbished Dell with a 6xxx processor it would be great.

    The E4xxx and E2xxx series have a very slow default FSB that can't be increased on Dells. They are great chips for custom builds, but not as hot on retail systems.
  4. The Refurbed Dells with AMD CPUs may actually be some of the better deals.
  5. Funny you should ask, Toms just did a review on it :lol:

    Different processor but they clocked them all to 2.4GHz to show cache differences.
