4th gen i3 vs 1st gen i7

Solution
It depends. For single-core processes, the I3 might prove to be the better because of its higher instructions per clock. However, overall the I7 still beats the I3 in terms of having 4 physical cores instead of 2. I'd say they are pretty similar, what are you looking to use it for? Make not that using 1st gen I7 means older motherboard.

It depends on exactly which i3 and i7 you want to compare. Most of the time though, the i3 will be faster since the newer architectures have ~25% better IPC, ~15% higher clock frequency, more up-to-date IO, new instruction sets, more power-efficient design and a few other extras..
 
An old-school i7 will generally work with motherboards which only support SATA II and PCI-E 2.0, which are obsolete. You can get better general Windows performance with a newer motherboard and i3, especially on a SATA III-compatible SSD, but still get slightly better gaming performance with a 1st gen i7.
