I currently own a Dimension E520 with a Pentium D 915 2.80GHz processor and i would like advice on if an Intel E6400 Core 2 Duo 2.13GHz processor would show any significant performance improvement after the upgrade.
My PC Specifications Are:
Pentium D 915 2.80GHz (4MB L2 Cache)
3GB DDR2 R.A.M
8400GS Graphics Card
305W Power Supply (Soon upgrading to 500W)
Please not that i checked if the E6400 is compatible with the motherboard and it is i would just like to know if the upgrade is worth it.
I would go with the E6400, the Pentium D 915 does not really have an efficient CPU architecture compared to the E6400. The processor is compatible with your motherboard so you should not have a problem. Take a look at this benchmark, it shows two different CPUs than the ones listed here but they are very closely related. It will show you clock speeds don't mean that much but architecture matters first.
Back when we released the Intel® Core™ 2 Duo E6400 2.13GHz I was checking to see how it would compare to our older processors. I found that Tom's had a bunch of benchmarks for the Intel Pentium® D 965 Extreme Edition 3.73GHz which was the fastest processor that we released before the Intel Core 2 Duo's. Comparing the two of these processor in 20 benchmarks that they had at the time the Intel Core 2 Duo E6400 beat the Intel Pentium® D 965 Extreme Edition 3.73GHz in 16 out of 20 benchmarks and only just lost on the other 4. In other words moving to the Intel Core 2 Duo's will give you a fairly major boost in performance.
