Intel i3 core 2.13G vs 2 duo 2.2G?

no comparison i3 will crush a duo

The Core 2 days are long over. Core i3, i5, and i7 have now taken the reigns.

The i class processors are to core 2 what core 2 was to Pentium 4. Faster, cooler, and way more expensive.

It'll all be obsolete by the time UPS get to your house anyway.

i3 is 32nm so it will run a lot faster + cooler. Though, my wolfdale at 3.8 will crush the i3 at 2.13   lets not overclock the i3 plz.

How many cores and threads does the i3 have?

the i3 is a dual core with HT, so 2 cores, 4 threads.

The i3 and C2D (and i5 and i7) have the same performance on single task at identical clock. Check SuperPi benchmarks: less than 5% difference.

Power consumption has improved a bit, but less than I hoped.

You may prefer a socket that has future and has upgrade capabilities.
