Let's hope AMD can deliver.

The fact of the matter is that Kaby Lake does not reflect that past performance bump, even six years later. I have a before-last-gen system Haswell 5820K in my personal system running at 4.4GHz and Kaby Lake does nothing to make me want to buy a new processor.
On the desktop gaming front in terms of benchmarks, we have seen Kaby Lake pull a general 20% advantage. Keep in mind these are comparing Kaby Lake and Sandy Bridge at identical clocks. But I will suggest that when we go back and test real-world gaming, that delta will get a lot more narrow. I am very interested in collecting data on this in the coming weeks.
When it comes to synthetic benchmarks, who really cares outside of companies that build the technology that they try to sell to us?
However, when we look at deeply threaded encoding real world usages, the Kaby Lake surely shows some prowess. But this is going to come down to a user case that either you know you are in need of or not. If you are doing a huge "Movie Maker" cut at home and are in a rush, and it cuts your render time down from 4 hours to 3 hours with your new 4K camera, then maybe Kaby Lake would be worth it to you. But the fact that we have to truly look at Intel's latest processor compared to its 5 year old processor in these terms is just sad. And this is looking through enthusiast rose colored glasses!
The Bottom Line
If you own a highly clocked 2600K/2500K Sandy Bridge processor and it is still giving you stable performance, it is hard for me to make the argument that it is time for you to upgrade, especially if you are a GPU-limited gamer.
The big Kaby Lake selling point that we are told through our technology connections throughout the world, is that ~80% of retail Kaby Lake 7600K/7700K processor will do 5GHz with full core loads and good cooling. (We have yet to see that proven as only 1 of our 3 7700K processors has done a truly stable 5GHz.) Surely 5GHz is a pinnacle that many of us enthusiasts have been waiting for...for years. Hell, it has only been 13 years since we showed HardOCP readers a Pentium 4 at 4.44GHz, right?
If you are looking for a new motherboard that has a laundry list of new features that tickles your fancy, I have no problem suggesting that Z170/Z270 is as good a jump-off point as any. You likely already know if you want or need those features on the Z270, or Z170 motherboards. From a purely CPU-centric scope, Intel has been failing the hardware enthusiast for years and looks to continue on that tradition with Kaby Lake. Intel has sorely beat AMD over the years, but now Intel is not even concerned with surpassing its own products.
AMD, it is your turn. We think we know where you are in terms of IPC; you had best get your pricing structure in line. Don't get greedy, deliver a solid non-beta platform, expand on core-width and chipset functionality going forward, and you are going to win a lot of us enthusiasts back. You get me close to parity with my Haswell, and I am building a new Ryzen system just on enthusiast principle alone.
Let's hope AMD can deliver.
