Compare Intel Core 2 Duo T5800 vs T6400

What are the differences if any between these two chips? Specs appear identical with exception of "manufacturing technology."

  1. Hi

    The T5800 is a 65nm, the T6400 is a 45nm, go with the 45nm much better CPU.

    Why much better ? What do you base this on ?
    As far as I can see from Intel's page, T6400's VCore range is wider (1000 mV - 1250 mV) than T5800's, so, even though it may be a tad cooler on idle, on usage it will heat up more than T5800 (its max temperature is 105C compared to T5800's, which is only 90C). So why's it better?
  4. Maybe because under the same load, the 45nm will be cooler...

    Nicolas Sarkozy already answered your question, the 45nm operates at a lower temperature.

    In idle mode, I guess, but the Intel page itself states that at maximum load, the 45nm will be hotter.
    Anyway, I'm looking for a well-backed argument, one that contains maybe isn't assertive enough.
  7. in idle mode, it will be cooler, but when using full load it will be hotter.
