Many thanks Head1985 for taking the time to compile all of this! I'm sitting on an i7 4790K @4.92 GHz with 2400 MHz CL11 RAM, and I was getting the twitch to upgrade after finding my 1080Ti is often CPU bottlenecked in AC: Origins @1440p. However, after seeing your results I am now convinced to stick with what I have got, possibly for a few more years!

If you're just gaming then that is wise. You'll be far better served using that upgrade twitch money on a better GPU.

He has a 1080Ti - there is no better GPU*.

*$1.2K GPU aside.

Indeed, I went quickly from 970 to 1070 to 1080 to 1080Ti as (used) bargains came along, but I've had the 1080Ti for a year now and even a used 2080Ti is priced at 200%-300% the price of what I paid for my 1080Ti with only a 30% performance uplift (and much less where CPU bottlenecked). Most of the time I am running games at 1440p at 100-165 FPS; CPU-bound drops and stutters are the only place where I could see improvement, but not sure that is worth forking out for until I hit games struggling more widely.

If I were in your shoes I would wait to see what next year brings (unless you have a must play game that is not fun playing due to performance reasons).
It seems unlikely Intel will bring much (maybe a 10 core?) but maybe AMD will release higher clock zen2 skus. 4.5+GHz all cores on 8+ cores should be a nice upgrade (I find it odd that the 3950X will have the higher boost clock). Can always go with a 9900K but it is hard to buy it when one can get 12 cores for the same price on a platform with newer features.

The more costly chips get the better binned dies, which happen to clock higher.
Sure. But it seems they are binning for speed/max boost and not cores.

You would expect some of the lower count cores skus to reach same or higher max/boost clocks from past generations.
I wonder if we will see a "refresh" next year with higher clocks.

Hmm I've seen reports of 3700x running better without SMT, could you test a couple games see if theres a few % in that?

@Head1985

If you don't mind me asking, what settings did you use to benchmark Fallout4? 1080p Ultra? Medium? Custom settings?

Better grab a chair and sit while waiting.

10nm only for mobile and server cpu's.

Really new Intel desktop cpu only with 7nm and that will be in 2022.
7nm production will start in 2021 but only for new gpu's and server cpu's.

Meanwhile AMD will have Zen3/Ryzen4000 in 2020 @ 7nm+ and Zen 4/Ryzen 5000@ 5nm in 2021.
So what? Zen2 has just proven to be on par performance per clock wise to Skylake - a 4 year old microarchitecture, mind you?. So it is reasonable to wait for the next larger IPC jump for the next upgrade. If Ryzen3/4 can catch Sunnycove and its successors in this regard is still unclear.

The 6700k@4.5-4.7Ghz with 3200 c14 ddr4 is 5-20% faster than Haswell in many titles, so you'd see much more of a gain than the OP. Haswell is quite old in the tooth IMO.

Yea, not to mention it still trails in clockspeed.

Really, which games? AVX loaded ones? I'd guess differences are smaller at 1440p. Indeed, it seems that my 4790K benchmark scores are generally close to a 7700K @4.7 GHz. In the worse case scenario, just behind a stock 7700K in Cinebench (AVX load). Some of the single-thread scores are up there with the 8700K and 9700K, hence solid gaming performance in all but heavily threaded games. The reality is that there was little progress from 4790K to 7700K, so if you find a 4790K that overclocks well then you approximate 7700K performance (minus ~200 MHz clock-to-clock, minus ~400 MHz AVX clock-to-clock):

CPU-Z: single 535, multi 2765
Geekbench: single 5791, multi 20079
Cinebench R20: single 475, multi 2330
Cinebench R15: single 200, multi 988
PassMark 9.0: single CPU 2947, 13804 CPU overall, 3391 RAM overall.
7-Zip: 29057 MIPS

@Head1985

Thanks! That's the tool I used to use some time ago when I last played Fallout4. I had forgotten the name of it. Anyway now I can replicate your settings this weekend.
