well this is where amd and intel have massively differed.
intel are releasing new gen cpus every year, but most of the recent one's have only been minor performance improvements, the last big performance improvement was sandy bridge. Although haswell has a moderate performance gain, and also with that said sandy bridge itself is now 30% or so behind on IPC as due to the sheer amount of incremental upgrades stacked up.
amd have been stuck on the same cpu tech for god knows how long, which is why they so uncompetitive, as the cpu's they currently sell are based on tech that is quite a few years old, on the flip side it means zen their next gen cpu will be a large performance jump from their existing tech which is a very bad buy right now.
so not having the latest intel generation of cpu is not a big deal providing you got something released in the last 3 years or so. The bigger changes have been on the chipset, for newer tech like sata3, pci express v3, m.2, ddr4, usb3 etc.
I think AMD's IPC is similar to core2duo chips. Since that gen intel had 2 large gains, from core2duo to the first gen core chips (core i5 750 gen) as that gen introduced on board memory controllers, then another nice jump with sandy bridge as starting that gen intel unlocked turbo mode v2.
