It's as fast as a similarily clocked 4790k in single thread performance, faster in both 4 thread and multithreaded performance. Like... why would I drop nearly $700 on a skylake platform to gain that 18% in single core performance. Not to mention it still smashes anything AMD has to offer... and my CPU is 5 years old. How's AMD still in business?
I feel like you and I are going to joust a bit between AMD and Intel from time to time.

Incoming AMD data dump.
Up to the Phenom II chips AMD was relatively or equally competitive with Intel. The next chip, Bulldozer was a big change in direction from a design standpoint as they focused heavily on using multiple "real" cores (not threads like Intel) and at a high clock speed while not being terribly efficient. The single core performance was roughly on par or even a little lower than the Phenom's in some instances, but they did have incredible multithread performance considering the cost and when they came out. I think the 8120's were $200 or so when new.
Vishera followed and somewhat improved core performance but overall was just a minor refresh and AMD has been a budget option since. The real problem here is that AMD was expecting or hoping that high core count would be useful and viable sooner than it was. Intel stuck with quad cores for a long time, and still are really with their i5's and HT'd i7's. Programming for multiple cores is more intensive than fewer, and that coupled with Intel holding more market share gave little incentive for software to make much use of all 8 cores. Windows at the time also had some slight issues with managing extra cores (core parking I think it was) and didn't really have much performance benefit from them.
AMD's survived the past few years off of their APU's, which were decent budget . The PS4 and Xbone both are powered by custom AMD APU's, so that certainly helped keep them afloat. Also they've been making GPU's that compete or even beat Nvidia throughout all of that. Their stock has doubled since the start of 2016, Polaris is anticipated to increase their GPU market share (which is already going up), and Zen is coming out at the end of 2016. Zen, if rumors and some benchmarks hold true, will compete with Intel again in performance and price. The single core performance is supposed to be I think somewhere around Broadwell/Skylake while offering higher core and thread counts.

I really am not terribly biased towards AMD products, believe it or not, I just respect them as a company and how they do business. Especially compared to Nvidia and Intel to a lesser degree. My first computer was on a budget and naturally had a Phenom II, a good choice at the time, and 5770 to match. I only got my 8320 since I couldn't afford a new board. That combined with my good GPU experiences with them just made me stick with them.
They definitely stumbled on the CPU front with Bulldozer/Vishera but to their credit they were just too ahead of the game in some regards. DirectX12 has made my mediocre old CPU breathe again and still hammer through new games with comfort. That combined with consoles moving to more cores has if anything made my CPU more viable now than it was a few years ago. GTA V runs better than GTA IV for me because it actually can
use my processor to it's extent rather than half of it at the most.
They do seem to get longevity for their products right at least. AMD cards have routinely increased in performance as they age compared to Nvidia's competition when they launched.
Hopefully they will be back in the CPU game in the next year. If not, I'm getting an Intel chip.
Edit: Sorry for the book, it just kinda kept going.
