Can someone quantify this difference to me?

[episodic]

Processor: Intel Pentium Dual Core E6700 (3.20GHz 2MB)



Processor: Intel Core i3-2100 (3.1GHz , 3 MB Cache)



Everything else being equal, how much faster is the i3 than the dual core e6700. I understand clockspeed doesn't equal speed of processor exactly.

Increase the Pentium's scores by ~ 15% and there you will have it.

Edit: Note this may not work for the synthetic benchmarks. But for FPS and timed benchmarks it should be in the ballpark.

the I3 is much faster than the old C2D.

This is probably the closest comparison you'll find.

The I3 is much better than those old C2D and Pentium Dual core processors.

Well 15% better at similar clockspeed would mean a 3.1ghz i3 would be like an 3.565ghz Petium dual core....I dont know if I would say much better....so over a 3.2ghz PDC that would be a little more then 10%.

I have always long felt 10% is about neglible, and I wouldn't upgrade a system for anything less then 30% improvement....

My last systems....

A64 to a X2 4400+
x2 4400+ to a E6400@3.4ghz
E6400@3.4ghz to dual opteron 265's at 275 speed (not much ocing options)
dual opterons to QX6700ES at 3.2ghz
QX6700ES to i2500K@4.5ghz

For typical daily use probably wouldn't notice much difference.

But if you're seriously stressing it, such as for video encoding, you're going to see about 35-40% faster results with the i3 (partly due to IPC, partly due to the HT that gives you more 'cores' than the Pentium offers).
