Question What is the generational improvement between 2nd-Gen Core (Sandy Bridge) quads, and 6th-Gen (Skylake) quads?

I told my friend that the newer Skylake system with DDR4-2666 and an i5-6600 was 30% faster than his older i5-2400 Sandy Bridge system with DDR3.

Was I accurate?

Close. Anandtech's review concluded Sky Lake was around 25% faster than Sandy Bridge.

Overall, Skylake is not an earth shattering leap in performance. In our IPC testing, with CPUs at 3 GHz, we saw a 5.7% increase in performance over a Haswell processor at the same clockspeed and ~ 25% gains over Sandy Bridge. That 5.7% value masks the fact that between Haswell and Skylake, we have Broadwell, marking a 5.7% increase for a two generation gap.

That was before all the Spectre and Meltdown stuff, which had much harsher penalties on generations older than Haswell if I recall correctly. Note that modern Windows versions should update the Microcode on their own, so using an old BIOS version won't save you from the mitigations performance penalty.

If you're going to bring Smeltdown into it, people really shouldn't be using anything older than Comet Lake if they can avoid it.
