In my experience, most modern games aren't CPU-bound anymore; more and more work is being pushed onto the GPU with every generation. My brother has a quad-core AMD CPU (don't remember which) with a powerful GPU, and his CPU is very rarely the bottleneck—there are few games he can't max out at 1080. Also, according to AMD's benchmarks, the Ryzen CPUs are very close to Intel's in single-threaded performance.

This. Gaming hasn't been bottlenecked by the CPU in a long time. Anything from an i5 up performs pretty much the same with the same GPU.

Entirely depends on the game.

If AMD makes a comeback, how did they do it? Not enough competition and Intel got complacent or what? Or did they just reach the limits and it's not possible anymore to keep the lead and prevent AMD from catching up?

They actually have a history of this. They did it with Athlon too.

AMD has a history of having dysfunctional R&D:

386DX - copied Intel design verbatim (1:1 microcode). Got sued, won only because Intel had multiple source agreements with IBM.

K6 - purchased NexGen. Designed 100% by outsiders.

K7 - once again hired somebody else's engineers. This time almost whole DEC Alpha design team.

K8 - DEC people had some more steam left in them.

K9-Zen period - no more companies to take over and claim credit for their designs, add terrible management bleeding engineering talent while burning money on stupid ideas like Seamicro = in house garbage with 50% Intel IPC.

Zen - finally managed to rehire competent ex DEC engineer Jim Keller after his successful career at Apple.

The IPC difference between Broadwell (6900K) and Kaby Lake (7700K) isn't that big. 5-10%. The only redeeming quality of the 7700K is that Intel was able to raise the turbo freq to 4.5 GHz, while the 1700X only boosts to 3.8 GHz. So yeah single-threaded perf will be higher with Intel.

Isn't the IPC difference basically 0 and the 7 series only has slightly higher frequencies due to the optimization cycle? So clock for clock 6 and 7 series CPU should yield the same performance. I should add that the above is the main reason the kaby lake release is so lackluster. There is very little reason to upgrade your desktop to a 7 series (laptops get power optimization and 4k playback support). It's also the…

You're talking about Skylake 6-series, the 6900K is Broadwell-E not Skylake despite being 6-branded.

I think the low TDPs have to be the scariest thing for Intel. Really interested to see what they can do in the 15-25W range for notebooks and their server stuff.

I have to wonder if the AMDs console win for the current generation gave them this badly needed R&D to reach decent TDP.

How so? The R&D budget is even lower than before AMD got the console deals.

SOme games still will require a beasty CPU.

Total War is one example.

The linked benchmarks are putting the $350 1700X about on par with the $1100 6900K when it comes to both single-threaded and multi-threaded performance. Both of those processors are 8-core/16-thread chips. Also the 1700K is a 95W TDP compared to the 6900K's 140W TDP.

Again, the 6900K is a two years old µarch, and not one which was considered a great release in the first place. The 1700X will not be competing against the 6900K because nobody gives a rat's ass about the 6900K, the 1700X will be competing against the 7700K and its ilk.

Uh oh, looks like Ryzen even beats Kaby Lake per clock and per core! https://news.ycombinator.com/item?id=13715973

Agreed... upgraded to an i7-4790K about 2 years ago, and really, other than software (x265) video encoding, I've been extremely happy... getting a big boost in performance for about the same price (for the cpu) as I paid 2 years ago would make me relatively happy. Now, just need a refresh on the GTX 1080, so that 4K gaming can be consistent at >= 60fps. ASIDE: I've been using nvenc with vbr2 for h.265 with very good…

Why not just add a second 1080? I've been thinking about doing that for a little while now that I got a good 4k display.

I could do that.. it's been a while since I've done SLI.. last time, I was running linux and dual displays, and had a LOT of issues (went back to windows), it was very bad. Might give it another try though... though not planning an upgrade for another year... got the 1080, and a 40" 4k late last year... I try to space out my upgrades. Carry over video card, then upgrade that later.

Its still better than nothing. AMD management is dysfunctional, they treat engineering as a cost and were cutting it badly during K9-K10 era.

I'm far too broke to shell out cash for a new Mobo and CPU right now, but I'm excited to see what this does to Intel's prices for older CPUs. I'd love to upgrade my i5-2400 soon-ish.

Unless you are regularly doing CPU intensive tasks you can probably stick with it a few more years. I noticed since I bought a SSD that most of time the hard drive is limiting the CPU. Until my DVD reader burned my desktop motherboard I was using a core2quad and it was still fast enough. No lag whatsoever. Now I'm using a laptop with the first gen I5 and I feel no need to upgrade it (I'm using it as a desktop battery…

In terms of general use, yeah definitely no problem with the CPU at all. It's zippy enough. But I also do a lot of CPU-intensive gaming (Cities: Skylines w/ tons of mods, RimWorld, Banished, etc.).
