I was thinking lately, is there an established difference between the Intel i3, i5 and i7 series of CPU's. I know that i7>i5>i3 in terms of speed, obviously, but is there a set difference between them such as architecture or layout of threads?

I don't know the architecture of the hardware, as I just know the performance. The i7 is hyperthreaded, so 4 cores, 8 virtual. i5 is 4 cores, 4 virtual (no HT) and i3 is 2 cores, 4 virtual. Depending on the applications you run, that's what matters in these processors.

Also you can't really run an i3 with a 7970, it will bottleneck. They're not only different in cores, but also strength and speed.

i3, i5, and i7 are all marketing terms.

There is some consistency differentiation on the desktop models, as i7 microprocessors generally have 4+ cores with Hyperthreading, i5 microprocessors generally have 4 cores without hyperthreading, i3 microprocessors have two cores with hyperthreading, and Pentium microprocessors have two cores without hyperthreading or Turbo Boost.

Mobile models, for notebooks, ultrabooks, and tablets do not follow such a pattern.
