There are really no actual performance gains between sandy bridge and kaby lake.
Its all in clock speed, which you could achieve with Sandy Bridge.
Isn't it funny that Ivy Bridge and Haswell and Broadwell couldn't hit the same clocks as Sandy Bridge and now Skylake can? SO that they can create a fake performance increase by slowly reaching the same performance they had before and pretending like their specialized architecture extensions which aren't used by 99% of applications are "gains".
Skylake is 23% faster than Sandy Bridge, clock for clock.
What about Skylake and Kabby Lake? They are both the same processor just KabyLake overclocked 7% faster and that's it.
Mostly it is process optimizations. It used to come in stepping, such as the Q6600 B3 vs G0 which happens naturally, as they continue to produce a CPU on a new process or uArch the yields get better and the process gets better which can result in lower power draw and normally higher clocks.
It looks like instead of keeping the same naming Intel is just re-launching them under a new retail name.
I can't blame them though. 10nm has proven difficult and I am sure 7nm will be even harder. Plus AMD, up until recently, has been mostly silent with a CPU that was just as old as Sandy Bridge but not nearly as good. Ryzen will probably help kick Intel into normal drive. I hope they go into overdrive but I don't think AMD could handle that. Their budget probably would not allow for it.
